•The digital gauge will likely indicate a higher
temperature when driving in hot weather, or up
mountain grades. It should not be allowed to
exceed the upper limits of the normal operating
range.
WARNING!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H,” turn the engine off immediately
and call an authorized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide
to look under the hood yourself, see “Maintaining
Your Vehicle.” Follow the warnings under the Cool-
ing System Pressure Cap paragraph. 3.

IMPORTANT:Do not continue driving with one or
more flat tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and steering. Repair
immediately using the dedicated tire repair kit and
contact your authorized dealership as soon as possible.
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 pres-
sure label, you should determine the proper tire infla-
tion 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. Accord-
ingly, 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 signifi-
cantly 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.
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 indi-
cator 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 rea-
sons, 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. 4

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary
areas are affected by improper tire pressure:
•Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause collisions.
• Underinflation increases tire flexing and can re-
sult in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.
(Continued)
WARNING! (Continued)
•Overinflated or underinflated tires can affect ve-
hicle handling and can fail suddenly, resulting in
loss of vehicle control.
• Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
• Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stabil-
ity of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.

STARTING AND OPERATING 219

(20°C) and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 23 psi
(159 kPa). This tire pressure is sufficiently low enough
to turn on the Tire Pressure Monitoring Telltale Light.
Driving the vehicle may cause the tire pressure to rise to
approximately 27 psi (186 kPa), but the Tire Pressure
Monitoring Telltale Light will still be on. In this situa-
tion, the Tire Pressure Monitoring Telltale Light will
turn off only after the tires are inflated to the vehicle’s
recommended cold tire pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings 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. Aftermarket wheels
can cause sensor damage. Using aftermarket tire
sealants may cause the Tire Pressure Monitoring
System (TPMS) sensor to become inoperable.
(Continued)
CAUTION! (Continued)
After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an autho-
rized dealership to have your sensor function
checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire 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.
