114 GETTING TO KNOW YOUR INSTRUMENT PANEL
Service 4WD Warning Light — If Equipped
This warning light will illuminate to
signal a fault with the 4WD system. If
the light stays on or comes on during
driving, it means that the 4WD system is not
functioning properly and that service is
required. We recommend you drive to the
nearest service center and have the vehicle
serviced immediately.
Service Adaptive Cruise Control (ACC)
Warning Light
This light will turn on when the ACC is
not operating and needs service
Ú page 146.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to
indicate a fault in the Forward Collision
Warning System. Contact an
authorized dealer for service Ú page 250.
Service Stop/Start System Warning Light
If Equipped
This warning light will illuminate when
the Stop/Start system is not
functioning properly and service is
required. Contact an authorized dealer for
service.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that
the tire pressure is lower than the
recommended value and/or that slow pressure
loss is occurring. In these cases, optimal tire
duration and fuel consumption may not be
guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
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 TPMS that illuminates a
low tire pressure telltale when one or more of
your tires is significantly underinflated.
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
underinflated tire causes the tire to overheat
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause damage
to the vehicle control system. It also could
affect fuel economy and driveability. If the
MIL is flashing, severe catalytic converter
damage and power loss will soon occur.
Immediate service is required.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair
kit and contact an authorized dealer as soon
as possible.
