INSTRUMENT CLUSTER WARNING LIGHTS
- Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
If the “ESC Activation/Malfunction Indicator Light” comes on continuously with the
engine running, a malfunction has been detected in the ESC system. If this light
remains on after several ignition cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h), we recommend you drive to
the nearest service center and have the vehicle serviced immediately.
The “ESC Activation/Malfunction Indicator Light” starts to flash as soon as the tires
lose traction and the ESC system becomes active. If the light begins to flash during
acceleration, ease up on the accelerator and apply as little throttle as possible. Be
sure to adapt your speed and driving to the prevailing road conditions. The light also
flashes when Traction Control System (TCS) is active. To improve the vehicle's
traction when starting off in deep snow, sand or gravel, it may be desirable to switch
the ESC system to Partial Off mode by momentarily pushing the ESC Off
switch.
– Tire Pressure Monitoring System (TPMS) Light
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.
WHAT TO DO IN EMERGENCIES
101

IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST
THE AIR PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE
VEHICLE PLACARD OR TIRE INFLATION PRESSURE LABEL LOCATED ON THE
DRIVER'S DOOR.
NOTE:
AFTER INFLATION, THE VEHICLE MAY NEED TO BE DRIVEN FOR 20 MINUTES
BEFORE THE FLASHING LIGHT WILL TURN OFF.
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 malfunc-
tion 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 malfunc-
tion 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.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C), and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermar-
ket wheels can cause sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a TPMS, as damage to the sensors
may result.

WARNING!
• Overloading of your tires is dangerous. Overloading can cause tire failure,affect vehicle handling, and increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never overload them.
•
Improperly inflated tires are dangerous and can cause collisions. Under-inflation is
the leading cause of tire failure and may result in severe cracking, component
separation, or “blow out”. Over-inflation reduces a tire’s ability to cushion shock.
Objects on the road and chuck holes can cause damage that results in tire failure.
Unequal tire pressures can cause steering problems. You could lose control of your
vehicle. Over-inflated or under-inflated tires can affect vehicle handling and can fail
suddenly, resulting in loss of vehicle control.
SPARE TIRES — IF EQUIPPED
NOTE:
For vehicles equipped with Tire Service Kit instead of a spare tire, please refer to “Tire
Service Kit” in “What To Do In Emergencies” on your DVD for further information.
CAUTION!
Because of the reduced ground clearance, do not take your vehicle through an
automatic car wash with a compact or limited-use temporary spare installed.
Damage to the vehicle may result.
Spare Tire Matching Original Equipped Tire And Wheel — If Equipped
Your vehicle may be equipped with a spare tire and wheel equivalent in look and function
to the original equipment tire and wheel found on the front or rear axle of your vehicle. This
spare tire may be used in the tire rotation for your vehicle. If your vehicle has this option,
refer to an authorized tire dealer for the recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use only. You can identify if your
vehicle is equipped with a compact spare by looking at the spare tire description on
the Tire and Loading Information Placard located on the driver’s side door opening or
on the sidewall of the tire. Compact spare tire descriptions begin with the letter “T”
or “S” preceding the size designation. Example: T145/80D18 103M.
T,S=T emporary Spare Tire
Since this tire has limited tread life, the original equipment tire should be repaired
(or replaced) and reinstalled on your vehicle at the first opportunity.
Do not install a wheel cover or attempt to mount a conventional tire on the compact spare
wheel, since the wheel is designed specifically for the compact spare tire. Do not install
more than one compact spare tire and wheel on the vehicle at any given time.

WARNING!
Compact spares are for temporary emergency use only. With these spares, do not
drive more than 50 mph (80 km/h). Temporary use spares have limited tread life.
When the tread is worn to the tread wear indicators, the temporary use spare tire
needs to be replaced. Be sure to follow the warnings, which apply to your spare.
Failure to do so could result in spare tire failure and loss of vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary emergency use only. This tire may look like the
originally equipped tire on the front or rear axle of your vehicle, but it is not. This
spare tire may have limited tread life. When the tread is worn to the tread wear
indicators, the temporary use full size spare tire needs to be replaced. Since it is not
the same as your original equipment tire, replace (or repair) the original equipment
tire and reinstall on the vehicle at the first opportunity.
Limited-Use Spare — If Equipped
The limited-use spare tire is for temporary emergency use only. This tire is identified
by a label located on the limited-use spare wheel. This label contains the driving
limitations for this spare. This tire may look like the original equipped tire on the front
or rear axle of your vehicle, but it is not. Installation of this limited-use spare tire
affects vehicle handling. Since it is not the same as your original equipment tire,
replace (or repair) the original equipment tire and reinstall on the vehicle at the first
opportunity.
WARNING!
Limited-use spares are for emergency use only. Installation of this limited-use
spare tire affects vehicle handling. With this tire, do not drive more than the speed
listed on the limit-use spare wheel. Keep inflated to the cold tire inflation
pressures listed on your Tire and Loading Information Placard located on the
driver’s side B-Pillar or the rear edge of the driver’s side door. Replace (or repair)
the original equipment tire at the first opportunity and reinstall it on your vehicle.
Failure to do so could result in loss of vehicle control.
