■Automatic shutoff
FCW may automatically shut itself off and the FCW indicator comes and stays on when:
• The temperature inside the system is high.
• The windshield is blocked by dirt, mud, leaves, wet snow, etc.
• You drive off-road or on a mountain road, or curved and winding road for an
extended period.
• You drive in bad weather (rain, fog, snow, etc.).
• The radar sensor cover is blocked by dirt, mud, leaves, wet snow, etc.
• An abnormal tire condition is detected (wrong tire size, flat tire, etc.).
Once the conditions that caused FCW to shut off improve or are addressed (e.g.,
cleaning), the system comes back on.
1 Automatic shutoff
To help reduce the likelihood that high interior
temperatures will cause the camera system to shut
off, when parking, find a shady area or face the front
of the vehicle away from the sun. If you use a
reflective sun shade, do not allow it to cover the
camera housing. Covering the camera can
concentrate heat on the camera.
If the CAMERA HOT message appears:•Use the climate control system to cool down the
interior and, if necessary, the defroster mode when
windows are fogged.•Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the FCW system.Models with information display

uuWhen Driving uVehicle Stability Assist (VSA® ), aka Electronic Stability Control (ESC), System
Driving
Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), SystemHelps 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 output and selectively applying the brakes.
When VSA® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.■
VSA ® Operation
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
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 ® 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 a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and cor ner 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.

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.

Important Safety Reminder
Like all assistance systems, LaneWatch has
limitations. Over reliance on LaneWatch may result in
a collision.
The LaneWatch function can be af fected 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 in jury 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.

uuWhen Driving uTire Pressure Monitoring System (TPMS)
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 multi-information display
*.
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.

TPMS Calibration
1 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 i ndicator 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. 523
The low tire pressure/TP MS indicator may come on
with a delay or may not come on at all when:•You rapidly accele rate, decelerate, or turn the
steering wheel.•You drive on snowy or slippery roads.•Snow chains are used.
The low tire pressure/TP MS indicator may come on
under the following conditions:•A compact spare tire is used.•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.

installed.•The calibration process requires approximately 30
minutes of cumulative driving at speeds between
30-60 mph (48-97 km/h).•During this period, if the ignition is turned on and
the vehicle is not moved within 45 seconds, you
may notice the low tire pressure indicator comes on
briefly. This is normal and indicates that the
calibration process is not yet complete.
You can cali brate the system using the audio/
information screen. 2 Customized Features P. 298
If the 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 the vehicle checked by a dealer.
We recommend that the tires be replaced with the
same brand, model, and size as the originals. Ask a
dealer for details.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Tire Pressure Monitoring System (TPMS) - Required Federal ExplanationEach tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufa cturer 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 tire s 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. Un der-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle's
handling an d stopping ability.U.S. models
