Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), System

Driving

Vehicle Stability Assist (VSA®), aka Electronic
Stability Control (ESC), System

VSA® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine and motor output and selectively applying the
brakes.

When VSA® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic system. You will also see
the indicator blink.

■

VSA® Operation

Vehicle Stability Assist (VSA®), aka Electronic Stability Control
(ESC), System

The VSA® may not function properly if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.

When the VSA® system indicator comes on and stays
on while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by an authorized
Honda Clarity Plug-In Hybrid dealer immediately.

The indicators for the Vehicle Stability Assist (VSA®)
System, Vehicle Stability Assist (VSA®) OFF, low tire
Pressure/TPMS and Collision Mitigation Braking
System

(CMBS

) may come on along with a

message in the driver information interface after
reconnecting the 12-volt battery. Drive a short
distance at more than 12 mph (20 km/h). The
indicator should go off. If it does not, have your
vehicle checked by an authorized Honda Clarity Plug-
In Hybrid dealer.

VSA® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.

The main function of the VSA® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.

This button is on the driver side control panel.
To partially disable VSA® functionality/
features, press and hold it until you hear a
beep.

Your vehicle will have normal braking and
cornering ability, but traction control function
will be less effective.

To restore VSA® functionality/features, press
the

(VSA® OFF) button until you hear a

beep.

VSA® is turned on every time you turn the
power system on, even if you turned it off the
last time you drove the vehicle.

■

VSA® On and Off

Vehicle Stability Assist (VSA®), aka Electronic Stability Control
(ESC), System

In certain unusual conditions when your vehicle gets
stuck in shallow mud or fresh snow, it may be easier
to free it with the VSA® temporarily switched off.

When the

button is pressed, the traction control

function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA® off if
you are not able to free it when the VSA® is on.

Immediately after freeing your vehicle, be sure to
switch VSA® on again. We do not recommend driving
your vehicle with the VSA® system switched off.

You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after turning the power
system on or while driving. This is normal.

Tire Pressure Monitoring System (TPMS)

Continued

Driving

Tire Pressure Monitoring System (TPMS)

Instead of directly measuring the pressure in each tire, the TPMS on this vehicle
monitors and compares the rolling radius and rotational characteristics of each
wheel and tire while you are driving to determine if one or more tires are
significantly under-inflated. This will cause the low tire pressure/TPMS indicator to
come on and a message to appear on the driver information interface.

You must start TPMS calibration every time you:
• Adjust the pressure in one or more tires.
• Rotate the tires.
• Replace one or more tires.

Before calibrating the TPMS:
• Set the cold tire pressure in all four tires.

2 Checking Tires P. 499

Make sure:
• The vehicle is at a complete stop.
• The gear position is in

(

• The power mode is in ON.

■

TPMS Calibration

Tire Pressure Monitoring System (TPMS)

The system does not monitor the tires when driving
at low speed.

Conditions such as low ambient temperature and
altitude change directly affect tire pressure and can
trigger the low tire pressure/TPMS indicator to come on.

Tire pressure checked and inflated in:

•

Warm weather can become under-inflated in
colder weather.

•

Cold weather can become over-inflated in warmer
weather.

The low tire pressure/TPMS indicator will not come
on as a result of over inflation.

The TPMS may not function properly if tire type and
size are mixed. Make sure to use the same size and
type of tire.

2 Checking and Maintaining Tires P. 499

The low tire pressure/TPMS indicator may come on
with a delay or may not come on at all when:

•

You rapidly accelerate, decelerate, or turn the
steering wheel.

•

You drive on snowy or slippery roads.

•

Snow chains are used.

The low tire pressure/TPMS indicator may come on
under the following conditions:

•

There is a heavier and uneven load on the tires,
such as when towing a trailer, than the condition at
calibration.

•

Snow chains are used.

message appears, repeat steps 4-6.

• The calibration process finishes

automatically.

TPMS Calibration

•

The calibration process requires approximately 30
minutes of cumulative driving at speeds between
30-65 mph (48-105 km/h).

•

During this period, if the power system is turned on
and the vehicle is not moved within 45 seconds, you
may notice the low tire pressure/TPMS indicator
comes on briefly. This is normal and indicates that
the calibration process is not yet complete.

If snow chains are installed, remove them before
calibrating the TPMS.

If the low tire pressure/TPMS indicator comes on even
when the properly inflated specified regular tires are
installed, have your vehicle checked by an authorized
Honda Clarity Plug-In Hybrid dealer.

We recommend that the tires be replaced with the
same brand, model, and size as the originals. Ask an
authorized Honda Clarity Plug-In Hybrid dealer for
details.

Driving

Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation

Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label.

(If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale

when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.

Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

428

When Driving

Tire Pressure Monitoring System (TPMS) - Required Federal Explanation

Driving

Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the
telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.

When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.

TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.

Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

LaneWatch

LaneWatch is an assistance system that allows you to check the passenger side rear
areas displayed on the audio/information screen when the turn signal is activated to
the passenger’s side. A camera in the passenger side door mirror monitors these
areas and allows you to check for vehicles, in addition to your visual check and use
of the passenger door mirror. You can also keep the system on for your convenience
while driving.

LaneWatch

Important Safety Reminder
Like all assistance systems, LaneWatch has
limitations. Over reliance on LaneWatch may result in
a collision.

The LaneWatch function can be affected by weather,
lighting (including headlights and low sun angle),
ambient darkness, camera condition, and loading.

The LaneWatch may not provide the intended display
of traffic to the side and rear under the following
conditions:

•

Your vehicle’s suspension has been altered,
changing the height of the vehicle.

•

Your tires are over or under inflated.

•

Your tires or wheels are of varied size or
construction.

WARNING

Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.

Do not rely only on LaneWatch while
driving.

Always look in your mirrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.

■

Reference Lines

Three lines that appear on the screen can give
an idea of how far the vehicles or objects on
the screen are from your vehicle, respectively.
If an object is near line 1 (in red), it indicates
that it is close to your vehicle whereas an
object near line 3 farther away.

LaneWatch

The LaneWatch camera view is restricted. Its unique
lens makes objects on the screen slightly look
different from what they are.

LaneWatch display does not come on when the gear
position is in

(

For proper LaneWatch operation:

•

The camera is located in the passenger side door
mirror. Always keep this area clean. If the camera
lens is covered with dirt or moisture, use a soft,
moist cloth to keep the lens clean and free of debris.

•

Do not cover the camera lens with labels or stickers
of any kind.

•

Do not touch the camera lens.

Reference Lines

The area around the reference line 1 (red) is very close to
your vehicle. As always, make sure to visually confirm
the safety of a lane change before changing lanes.

The distance between your vehicle and lines 1, 2 and
3 on the screen vary depending on road conditions
and vehicle loading. For example, the reference lines
on the screen may seem to appear closer than the
actual distances when the rear of your vehicle is more
heavily loaded.

Consult an authorized Honda Clarity Plug-In Hybrid
dealer if:

•

The passenger side door mirror, or area around it is
severely impacted, resulting in changing the
camera angle.

•

The LaneWatch display does not come on at all.
