7. Temperature Gauge• The pointer shows engine coolant temperature. Thepointer positioned within the normal range indicates
that the engine cooling system is operating satisfacto -
rily.
• The pointer will likely indicate a higher temperature when driving in hot weather, up mountain grades, or
when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
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. Refer to “Cooling System Pressure
Cap” in “Servicing And Maintenance” for further
information if you decide to look under the hood.
CAUTION!
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

Oil Life Reset
Your vehicle is equipped with an engine oil change indicator
system. The “Oil Change Required” message will display in
the instrument cluster display for five seconds after a single
chime has sounded, to indicate the next scheduled oil change
interval. The engine oil change indicator system is duty cycle
based, which means the engine oil change interval may fluc -
tuate, dependent upon your personal driving style.

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 Tire Pressure Monitoring System (TPMS) that illumi-
nates 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.
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 pres
-
sure telltale.
Your vehicle has also been equipped with a TPMS malfunc -
tion 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 indi -
cator 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
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.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system. Failure
to pass could prevent vehicle registration.For states that require an Inspection and Mainte -
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not on
when the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a depleted battery or a battery replace -
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following: 1. Cycle the ignition switch to the ON position, but do not
crank or start the engine.
NOTE:
If you crank or start the engine, you will have to start this test
over.
2. As soon as you cycle the ignition switch to the ON posi -
tion, you will see the “Malfunction Indicator Light (MIL)”
symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn OFF the igni -
tion or start the engine. This means that your vehicle's
OBD II system is not ready and you should not proceed
to the I/M station.
• The MIL will not flash at all and will remain fully illu -
minated until you place the ignition in the off position
or start the engine. This means that your vehicle's OBD
II system is ready and you can proceed to the I/M
station.

202 SAFETY
(Continued)
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.
WARNING!
• Electronic Stability Control (ESC) cannot prevent the natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC equipped
vehicle must never be exploited in a reckless or
dangerous manner which could jeopardize the user’s
safety or the safety of others.
• Vehicle modifications, or failure to properly maintain your vehicle, may change the handling characteristics
of your vehicle, and may negatively affect the perfor -
mance of the ESC system. Changes to the steering
system, suspension, braking system, tire type and size
or wheel size may adversely affect ESC performance.
Improperly inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle modification or
poor vehicle maintenance that reduces the effective -
ness of the ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal injury and
death.

SAFETY 227
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
NOTE:
The TPMS Warning Light will illuminate in the instrument
cluster and a chime will sound when tire pressure is low in
one or more of the four active road tires. In addition, the
instrument cluster will display a graphic showing the pres -
sure values of each tire with the low tire pressure values in a
different color, or the Uconnect radio will display a TPMS
message, when this occurs you must increase the tire pres -
sure to the recommended cold placard pressure in order for
the TPMS Warning Light to turn off.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three hours,
or driven less than 1 mile (1.6 km) after a three hour period.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires” in “Servicing And Maintenance” for infor -mation on how to properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is driven - this is
normal and there should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire pres
-
sure as long as the condition exists, and will not turn off until
the tire pressure is at or above the recommended cold
placard pressure. Once the low TPMS Warning Light illumi -
nates, increase the tire pressure to the recommended cold
placard pressure in order for the TPMS Warning Light to
turn off. The system will automatically update and the TPMS
Warning Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
