Start/Stop*

Some engine and gearbox combinations come
fitted with a Start/Stop function which engages
in the event of e.g. stationary traffic or waiting at
traffic lights - the engine is then switched off
temporarily and restarts automatically when the
journey is due to continue.

Environmental care is one of Volvo Car Corpora-
tion's core values and it influences all of our
operations. This target orientation has resulted in
several separate energy-saving functions of
which Start/Stop is one, all with the collective
task of reducing fuel consumption, which in turn
helps to reduce exhaust emissions.

General information on Start/Stop

The engine is switched off - it becomes quieter and

cleaner...

The Start/Stop function gives the driver the
opportunity for a more active environmentally

conscious way of driving the car by means of
being able to allow the engine to stop automati-
cally, whenever appropriate.

The car's menu system MY CAR (p. 113) under
heading

Drive-E

contains information on Volvo's

Start/Stop system, as well as recommendations
for energy-saving driving techniques.

Manual or automatic gearbox

Note that there are differences in the Start/Stop
function depending on whether the gearbox is
manual or automatic.

Start/Stop* - function and operation

The Start/Stop function is activated automati-
cally when the engine is started with the key.

The Start/Stop function is acti-
vated automatically when the
engine is started with the key.
The driver is made aware of the
function by the function's
On/Off button symbol lighting
up in the combined instrument
panel and the On/Off button
lamp illuminating.

All of the car's normal systems

such as lighting, radio, etc. work as normal even
with an engine that has stopped automatically,
except that some equipment may have the func-
tion temporarily reduced, e.g. the climate control
system's fan speed or extremely high volume on
the audio system.

Auto-stopping the engine

The following is required for the engine to auto-
stop:

STARTING AND DRIVING

280

Conditions

M/A

Declutch, set the gear lever in neutral
position and release the clutch pedal -
the engine stops automatically.

Stop the car with the foot brake and
then keep your foot on the pedal - the
engine stops automatically.

M = Manual gearbox, A = Automatic gearbox.

If the ECO function is activated
then the engine may auto-stop
before the car is completely
stationary.

For certain engine variants the engine may auto-
stop before the car is stationary regardless of
whether the ECO function is activated.

When the engine is auto-stopped, the
combined instrument panel's symbol
for the Start/Stop function illuminates.

Auto-starting the engine

Conditions

M/A

With the gear lever in neutral position:

1. Depress the clutch pedal or press

the accelerator pedal - the engine
starts.

2. Engage a suitable gear and drive.

Release the foot pressure on the foot
brake - the engine starts automatically
and the journey can continue.

Maintain foot pressure on the foot
brake and depress the accelerator
pedal - the engine auto-starts.

The following option is also available on
a downhill gradient:

•

Release the foot brake and let the
car move off - the engine starts
automatically when the speed
exceeds normal walking pace.

M +

M = Manual gearbox, A = Automatic gearbox.

Deactivating the Start/Stop function

In certain situations, it may
advisable to temporarily switch
off the automatic Start/Stop
function - this is carried out
with a push of this button.

Disengaged function is indicated by
the combined instrument panel's
Start/Stop symbols and the button's
lamp extinguishing.

The Start/Stop function is disengaged until it is
reactivated with the button or until the next time
the engine is started with the key.

Start assistance HSA

The foot brake can also be released on an uphill
slope to auto-start the engine - the HSA (p. 278)
(Hill Start Assist) function prevents the car from
rolling backwards.

HSA means that the pressure in the brake sys-
tem remains temporarily available while the driv-
er's foot is moved from the brake pedal to the
accelerator pedal for driving off with the engine
having stopped automatically. The temporary
braking effect releases after a couple of seconds
or when the driver accelerates.

Drive mode ECO*

ECO

is an innovative Volvo function for auto-

matic-gearbox cars, capable of reducing fuel
consumption by up to 5%, depending on the
driver's driving style. The function gives the driver
the option of a more active environmentally con-
scious way of driving.

General

The following are changed
upon activation of the ECO
function:

•

Gearbox gearshift points.

•

Engine management and response from the
accelerator pedal.

•

Start/Stop function - the engine can also
auto-stop before the car has stopped down
to being completely stationary.

•

The Eco Coast function is activated - engine
braking ceases.

•

Climate control system settings - some elec-
tricity consumers are deactivated or operate
at reduced power.

When the ECO function is activated, several
parameters in the climate control system's
settings are changed, and several electricity
consumer functions are reduced. Certain set-
tings can be reset manually, but full function-
ality is only restored by deactivating the ECO
function.

ECO - Operation

ECO On/Off

ECO symbol

The ECO function is deactivated when the engine
is switched off, and must therefore be activated
after each time the engine is started. There are
exceptions for certain engines. However, it is

easily verified by means of both the combined
instrument panel's

ECO

symbol and the ECO-

button's lamp illuminating when the function is
activated.

ECO function On or Off

Disengaged ECO function is
indicated by the combined
instrument panel

ECO

symbol

and the ECO button lamp extin-
guishing. The function is then
switched off until it is reactiva-
ted with the ECO button.

Eco Coast - Function

The Eco Coast subfunction means in practice
that engine braking is deactivated, meaning in
turn that the car's kinetic energy is used to coast
for longer distances. When the driver releases
the accelerator pedal the gearbox is automatically
disengaged from the engine whose speed is
reduced to idling speed with minimum consump-
tion.

This function is intended for use in the event of
an anticipated reduction in speed, e.g. to coast
into a zone with a lower speed limit.

Eco Coast enables proactive driving where the
driver can use the so-called "Pulse & Glide"
technique and a minimum of braking.

Not possible on the V40 CROSS COUNTRY with AWD.

STARTING AND DRIVING

288

A combination of Eco Coast and temporarily
deactivated ECO function can also collectively
contribute to reduced consumption. Accordingly:

•

Active Eco Coast: Long coasting without
engine braking = Low consumption

and

•

Deactivated ECO function: Short coasting
with engine braking = Minimum consump-
tion.

General information on climate control
(p. 126)

However, to achieve optimal low fuel con-
sumption, Eco Coast in combination with
short coasting distances should generally be
avoided.

Activating Eco Coast

The function is activated when the accelerator
pedal is fully released, in combination with the
following parameters:

•

ECO button activated

•

Gear selector in D position

•

Speed within the range of
approx. 65-140 km/h (40-87 mph)

•

The road's downhill gradient is not steeper
than approx. 6%.

Deactivate Eco Coast

In certain situations it may be desirable to deacti-
vate the Eco Coast function. Examples of such
situations include:

•

on steep downhill gradients - to be able to
use engine braking.

•

before an imminent overtaking manoeuvre -
in order to be able to complete it in the saf-
est possible way.

Deactivating Eco Coast and returning to engine
braking can be performed as follows:

•

Press the ECO button.

•

Move the gear lever to manual "S+/-" posi-
tion.

•

Change gear with the steering wheel paddle
shifters.

•

Actuate the accelerator or brake pedal.

Eco Coast - Limitations

The function is not available if:

•

cruise control is activated

•

the road's downhill gradient is steeper than
approx. 6%

•

manual gear changing is performed with the
steering wheel paddle shifters

•

engine and/or gearbox are not at normal
operating temperature

•

the gear selector is moved from D- to "S+/-"
position

•

speed is outside the range of
approx. 65-140 km/h (40-87 mph).

More information and settings

The car's menu system MY CAR contains further
information on the ECO concept - see the sec-
tion MY CAR (p. 113).

All Wheel Drive

(AWD)*

All Wheel Drive (AWD – All Wheel Drive) means
that the car is driven by all four wheels. All-wheel
drive is always engaged.

AWD principle

The power is automatically distributed between
the front and rear wheels. An electronically con-
trolled clutch system distributes the power to the
wheels that have the best grip on the current
road surface. This provides the best traction and
prevents wheel spin. Under normal driving condi-
tions, the majority of power is transmitted to the
front wheels.

All-wheel drive improves driving safety in rain,
snow and icy conditions.

Hill Descent Control (HDC) (p. 289)

Hill Descent Control (HDC)

HDC can be compared to an automatic engine
brake. When you release the accelerator on
downhill gradients the car is normally braked by
means of the engine striving for low engine
idling speeds, so-called engine braking. But the
steeper the roadway and the more load in the
car, the faster the car coasts despite engine
braking - the HDC function compensates for this
with automatic brake intervention.

General information on HDC

The function makes it possible to increase/
reduce speed on steep downhill gradients, with a
foot only on the accelerator pedal, without using
the footbrake. The sensitivity of the accelerator
pedal decreases and becomes more precise by
means of the full actuation of the pedal being
restricted to adjusting engine speed within a lim-
ited range. The brake system brakes itself and
provides the car with a low and even speed, so
allowing the driver to fully focus on steering.

HDC is particularly helpful on steep gradients
with an uneven road surface and slippery sec-
tions. E.g. when launching a boat on a trailer from
a ramp.

V40 CROSS COUNTRY

The figure is schematic - details may vary depending on market and model.

HDC is only possible on the V40 CROSS COUNTRY AWD.

STARTING AND DRIVING

* Option/accessory.

290

WARNING

HDC does not work in all situations but is

designed merely as a supplementary aid.
The driver always bears ultimate responsibility

for ensuring that the vehicle is driven safely.

Function

HDC On/Off.

HDC is activated or deactivated with one of the
centre console's switches. The lamp within it illu-
minates when the function is activated.

When HDC is working normally the com-
bined instrument panel's symbol illumi-

nates combined with the text message

Hill

descent control ON

With manual transmission, the function works
only on first gear and reverse gear.

With automatic transmission, gear 1 must be
selected in manual gearshift mode (+S-), or R
must be selected. This is indicated by the number

in the combined instrument panel, see

Automatic gearbox - Geartronic

* (p. 274).

HDC cannot be activated on an automatic
gearbox in position D.

Operation

HDC allows the car to roll at a maximum of
10 km/h (6 mph) forwards with engine braking
and 7 km/h (4 mph) backwards. However, any
speed within the gear's speed register can be
selected using the accelerator pedal. When the
accelerator pedal is released, the car is braked
quickly to 10 or 7 km/h (6 or 4 mph) respec-
tively, irrespective of the hill's gradient and with-
out the need for the foot brake.

The brake lights come on automatically when the
function is operating. The driver can brake or stop
the car at any time by using the footbrake.

HDC is deactivated:

•

with the centre console's On/Off button

•

if a gear other than 1 or R is selected on a
manual gearbox

•

if a gear other than 1 or R is selected in
manual gearshift mode on an automatic
gearbox.

The function can be disengaged at any time. If it
takes place on a steep downhill gradient then the
braking effect will not release directly, but slowly
instead.
