Distance Alert*

The Distance Alert

function can help the driver

become aware if the time interval to the vehicle
in front is too short.

However, the vehicle must be equipped with a
head-up display in order to display the Distance
Alert, which will then be indicated by a symbol
on the windshield as long as the time interval to
the vehicle ahead is shorter than the set time
interval.

Distance Alert is active at speeds above 30 km/h
(20 mph) and only reacts for vehicles ahead mov-
ing in the same direction as your vehicle. No dis-
tance information is provided for oncoming, slow-
moving or stationary vehicles.

NOTE

•

Distance Alert is only available in vehicles
that can display information on the wind-
shield with a head-up display.

•

Distance Alert is deactivated while Adap-
tive Cruise Control or Pilot Assist is
active.

WARNING

Distance Alert only reacts of the time interval

to the vehicle ahead is shorter than the preset

value – vehicle speed is not affected.

WARNING

•

The radar sensor has a limited field of
vision. In some situations, it may detect a
vehicle later than expected or not detect
other vehicles at all.

•

The radar sensor cannot cover all driving
situations and traffic, weather and road
conditions.

•

The driver is responsible for maintaining a
safe distance and speed and must inter-
vene if the various driver support systems
do not maintain a suitable speed or suita-
ble distance to the vehicle ahead.

•

Maintenance of radar sensor components
may only be performed by a trained and
qualified Volvo technician.

•

Strong sunlight, reflections from the road
surface, strong lighting contrasts or using
sunglasses may make the warning light in
the windshield difficult to see. Poor
weather or winding roads can affect the
radar sensor's capacity to detect vehicles
ahead.

•

A vehicle's size (e.g., a motorcycle) can
also affect the radar sensor's capacity to
detect another vehicle. This may result in
the warning light illuminating at a shorter
distance than the one that has been set
or not illuminating at all.

•

High speeds may also result in the warn-
ing light illuminating at a shorter distance
than the one that has been set due to
limitations in the radar sensor's range.

NOTE

The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit limitations".

Adaptive Cruise Control*

Adaptive Cruise Control (ACC

) helps the

driver maintain a constant speed with a set time
interval to the vehicle ahead.

Adaptive Cruise Control helps provide a more
relaxed driving experience on long trips on high-
ways or long, straight roads with even traffic
flows.

The camera/radar sensor measures the distance to the
vehicle ahead

The driver sets a speed and a time interval to the
vehicle ahead. If the camera/radar sensor detects
a slower-moving vehicle ahead, your vehicle's
speed will be automatically adapted according to
the set time interval to that vehicle. When there
are no longer slower-moving vehicles ahead, the
vehicle will return to the set speed.

DRIVER SUPPORT

293

WARNING

•

The Adaptive Cruise Control function is
supplementary driver support intended to
facilitate driving and help make it safer –
it cannot handle all situations in all traffic,
weather and road conditions.

•

The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).

•

Adaptive Cruise Control is not a substi-
tute for the driver's attention and judg-
ment. The driver is always responsible for
ensuring the vehicle is driven in a safe
manner, at the appropriate speed, with an
appropriate distance to other vehicles,
and in accordance with current traffic
rules and regulations.

NOTE

Depending on market, this function may be
either Standard or Optional.

Adaptive Cruise Control regulates speed by
accelerating and braking. It is normal for the

brakes to emit a slight sound when they are
being used to adjust speed.

Adaptive Cruise Control always attempts to regu-
late speed smoothly. The driver must apply the
brakes in situations requiring immediate braking.
For example, when there are great differences in
speed between vehicles or if the vehicle ahead
brakes suddenly. Due to limitations in the radar
sensor, braking may occur unexpectedly or not at
all.

Adaptive Cruise Control is designed to follow a
vehicle ahead in the same lane and maintain a
time interval to that vehicle set by the driver. If the
radar sensor does not detect a vehicle ahead, it
will instead maintain the speed set by the driver.
This will also happen if the speed of the vehicle
ahead exceeds the set speed for your vehicle.

•

Adaptive Cruise Control can follow another
vehicle at speeds from a standstill up to
200 km/h (125 mph).

WARNING

•

Adaptive Cruise Control is not a collision
avoidance system. The driver is always
responsible and must intervene if the sys-
tem fails to detect a vehicle ahead.

•

Adaptive Cruise Control does not brake
for people or animals and does not brake
for small vehicles, such as bikes and
motorcycles. Similarly, it does not brake
for low trailers, oncoming, slow-moving or
stationary vehicles and objects.

•

Do not use Adaptive Cruise Control in
demanding situations, such as in city traf-
fic, at intersections, on slippery surfaces,
with a lot of water or slush on the road, in
heavy rain/snow, in poor visibility, on
winding roads, or on on/off ramps.

CAUTION

Maintenance of Adaptive Cruise Control com-
ponents may only be performed by a work-
shop – an authorized Volvo workshop is rec-
ommended.

NOTE

•

The greater the vehicles' speed, the
greater the distance between them for a
set time interval.

•

Only use the time intervals permitted by
local traffic regulations.

•

If the Adaptive Cruise Control does not
seem to respond with a speed increase
when activated, it may be because the
time interval to the vehicle ahead is
shorter than the set time interval.

WARNING

•

Only use a time interval suitable for the
current traffic conditions.

•

The driver should be aware that short
time intervals give them limited time to
react and act to any unforeseen traffic
situation.

Setting how ACC should maintain
distance* to the vehicle ahead

A number of different settings can be made for
how Adaptive Cruise Control should maintain a
time interval to the vehicle ahead. Settings are
made using the DRIVE MODE controls.

Select one of the following:

•

Eco

- ACC will focus on providing optimal

fuel economy, which will increase the time
interval to the vehicle ahead.

•

Comfort

- ACC will focus on following the

set time interval to the vehicle ahead as
smoothly as possible.

•

Dynamic

- ACC will focus on following the

set time interval to the vehicle ahead more
exactly, which could mean faster acceleration
and heavier braking.

For more information, see "Drive modes".

Additional information is provided in the sections
"Managing Cruise Control speed" and "ECO

). If any of these other systems stops

working, Adaptive Cruise Control will automati-
cally switch off.

WARNING

With automatic standby mode, the driver is

warned by an acoustic signal and a message

on the instrument panel.

•

The driver must then regulate vehicle
speed, apply the brakes if necessary, and
maintain a safe distance to other vehicles.

Adaptive Cruise Control may go into standby
mode if:

•

your vehicle's speed goes below 5 km/h
(3 mph) and ACC cannot determine if the
vehicle ahead is stationary or if it is another
object, e.g. a speed bump.

•

your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
ACC no longer has a vehicle to follow.

•

the driver opens the door.

•

the driver unbuckles the seat belt.

•

the engine speed (rpm) is too low/high.

•

one or more of the wheels lose traction.

Passing assistance with Adaptive

Cruise Control

Adaptive Cruise Control (ACC

) can assist the

driver when passing other vehicles.

How passing assistance works

When ACC is following another vehicle and you
indicate that you intend to pass that vehicle by
using the turn signal

, Adaptive Cruise Control

will begin accelerating toward the vehicle ahead
before your vehicle has moved into the passing
lane.

The function will then delay a speed reduction to
avoid early braking as your vehicle approaches a
slower-moving vehicle.

The function remains active until your vehicle has
passed the other vehicle.

WARNING

Please note that this function can be acti-

vated in more situations than just passing

another vehicle, such as when a direction indi-

cator is used to indicate a lane change or

before exiting to another road – the vehicle

will then briefly accelerate.

Starting passing assistance with

Adaptive Cruise Control

Several conditions must be met for passing
assistance to be possible.

Requirements for passing assistance

In order to activate passing assistance:

•

your vehicle must be following a vehicle
ahead (target vehicle)

•

your vehicle's current speed must be
at least 70 km/h (43 mph)

•

the set speed for ACC must be high
enough to safely pass another vehicle.

Starting parking assistance

To start passing assistance:

–

Turn on the left turn signal.
> Passing assistance will start.

Limitations of passing assistance

with Adaptive Cruise Control

Passing assistance functionality may be reduced
in certain situations.

WARNING

The driver should be aware that if conditions

suddenly change when using Parking Assis-

tance, the function may implement an unde-

sired acceleration in certain conditions.
Some situations should be avoided, e.g. if:

•

the vehicle is approaching an exit in the
same direction as passing would normally
occur

•

the vehicle ahead slows before your vehi-
cle has had time to switch to the passing
lane

•

traffic in the passing lane slows down

•

a vehicle for right-hand traffic is driven in
a country with left-hand traffic (or vice
versa).

Situations of this type can be avoided by tempo-
rarily putting ACC

in standby mode.

Switching target vehicles with

Adaptive Cruise Control

At certain speeds, models with automatic trans-
missions and Adaptive Cruise Control (ACC

)

can switch target vehicles.

Switching target vehicles

If the target vehicle ahead turns suddenly, there may be
stationary traffic ahead.

When Adaptive Cruise Control is actively follow-
ing another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a moving
vehicle to a stationary vehicle, Adaptive Cruise
Control will brake for the stationary vehicle.

WARNING

When Adaptive Cruise Control follows another

vehicle at speeds over approx. 30 km/h

(20 mph) and changes target vehicle – from a

moving vehicle to a stationary one – Adaptive

Cruise Control will ignore the stationary vehi-

cle and instead accelerate to the stored

speed.

•

The driver must then intervene and apply
the brakes.

Automatic standby mode when switching
targets

Adaptive Cruise Control will be disabled and go
into standby mode:

•

if your vehicle's speed goes below 5 km/h
(3 mph) and Adaptive Cruise Control cannot
determine if the target object is a stationary
vehicle or another object, e.g. a speed bump.

•

if your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so that
Adaptive Cruise Control no longer has a vehi-
cle to follow.

Automatic braking with Adaptive

Cruise Control

The Adaptive cruise control (ACC

) has a spe-

cial brake function in slow traffic and while sta-
tionary.

Braking function in slow traffic and at a
standstill

In slow-moving, stop-and-go traffic or when stop-
ped at a traffic light, driving will resume automati-
cally if the vehicle is stopped for less than
approx. 3 seconds. If it takes more than 3 sec-
onds for the vehicle ahead to begin moving again,
Adaptive Cruise Control will go into standby
mode and the Auto-hold brake function will acti-
vate.

–

Adaptive Cruise Control can be reactivated in
one of the following ways:

•

Pressing the

button on the steering

wheel keypad.

•

Pressing the accelerator pedal.

> Adaptive Cruise Control will resume fol-

lowing the vehicle ahead if it begins to
move within approx. 6 seconds.

NOTE

ACC can keep the vehicle stationary for no
more than 5 minutes – after that time the
parking brake is applied and Adaptive Cruise
Control is deactivated.

The parking brake must be released before
Adaptive Cruise Control can be reactivated.

Deactivation of the Auto-hold brake function

In certain situations, Auto-hold will be deactivated
when the vehicle is at a standstill and Adaptive
Cruise Control will go into standby mode. This
means that the brakes will be released and the
vehicle could begin to roll. The driver must
actively apply the brakes to keep the vehicle sta-
tionary.

This can occur if:

•

the driver depresses the brake pedal

•

the parking brake is applied

•

the gear selector is moved to the P, N or R
positions

•

the driver puts Adaptive Cruise Control in
standby mode.

Auto Activate Parking Brake

In certain situations, the parking brake will be
applied to keep the vehicle at a standstill.

ited functionality in certain situations.

Steep roads and/or heavy loads

Adaptive Cruise Control is primarily intended to
be driven on flat roads. The function may not be
able to maintain the correct time interval to the
vehicle ahead when driving down steep hills. The
driver should be extra attentive and prepared to
apply the brakes.

•

Do not use Adaptive Cruise Control if the
vehicle is carrying a heavy load or towing a
trailer.

Other limitations

•

The

Off Road

drive mode cannot be

selected if Adaptive Cruise Control is acti-
vated.
