80 GETTING TO KNOW YOUR INSTRUMENT PANEL
Change Engine Oil — If Equipped
Your vehicle may be equipped with an engine oil change
indicator system. The “Change Engine Oil” message will
display in the instrument cluster display. The engine oil
change indicator system is duty cycle based, which means
the engine oil change interval may fluctuate, dependent
upon your personal driving style.
Unless reset, this message will continue to display each time
you turn the ignition switch to the ON/RUN position. To
turn off the message temporarily, push and release the
MENU button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure.
1. Turn the ignition switch to the ON position (do not start the engine).
2. Fully push the accelerator pedal slowly, three times, within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:
If the indicator message illuminates when you start the
vehicle, the oil change indicator system did not reset. If
necessary, repeat this procedure.

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
tires or wheels on your vehicle to ensure that the replace
-
ment or alternate tires and wheels allow the TPMS to
continue to function properly.
Vehicle Security Warning Light
This warning light will illuminate when the vehicle
security alarm system has detected an attempt to
break into the vehicle. 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.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an
authorized dealer to have your sensor function checked.

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
replacement. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
WARNING!
• ONLY an authorized service technician should connect equipment to the OBD II connection port in order to
read the VIN, diagnose, or service your vehicle.
• If unauthorized equipment is connected to the OBD II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information stored in your vehicle systems, including personal
information.

ESC Activation/Malfunction Indicator Light And ESC
OFF Indicator Light The ESC Activation/Malfunction Indicator Light in
the instrument cluster will come on when the igni -
tion switch is turned to the MAR (ON/RUN) posi -
tion for four seconds. 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 (km) at speeds greater
than 30 mph (48 km/h), see an authorized dealer as soon as
possible to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light (located in
the instrument cluster) starts to flash as soon as the tires lose
traction and the ESC system becomes active. The ESC Activa
-
tion/Malfunction Indicator Light also flashes when TCS is
active. If the ESC Activation/Malfunction Indicator 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.
NOTE:
• The ESC Activation/Malfunction Indicator Light and the ESC OFF Indicator Light come on momentarily each time
the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system will be ON even if it was turned off previously.
The ESC OFF Indicator Light indicates the Electronic
Stability Control (ESC) is partially off.
• 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 103
AUXILIARY DRIVING SYSTEMS
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.
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 tire pressure warning (TPMS
Warning Light) illuminates, you must increase the tire pres -
sure to the recommended cold placard pressure in order for
the TPMS Warning Light to turn off. The system will auto -
matically 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 infor -
mation.
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the recom -
mended cold placard pressure in order to turn the TPMS
Warning Light off.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F (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 approx -
imately 23 psi (158 kPa). This tire pressure is sufficiently low
enough to turn on the TPMS Warning Light. Driving the
vehicle may cause the tire pressure to rise to approximately
4

104 SAFETY
27 psi (186 kPa), but the TPMS Warning Light will still be on.
In this situation, the TPMS Warning Light will turn off only
after the tires are inflated to the vehicle’s recommended cold
placard pressure value.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.
• The TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure using an accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
CAUTION!
• The TPMS has been optimized for the original equip -
ment 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. After -
market wheels can cause sensor damage.
• Using aftermarket tire sealants may cause the Tire Pres -
sure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended 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 TPMS sensor.

• Seat Belt Pretensioners
Air Bag Warning Light
The Occupant Restraint Controller (ORC) monitors the
readiness of the electronic parts of the air bag system
whenever the ignition switch is in the AVV/START or
MAR/ACC/ON/RUN position. If the ignition switch is in the
STOP/OFF/LOCK position the air bag system is not on and the air
bags will not inflate.

The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.

The ORC turns on the Air Bag Warning Light in the instrument
panel for approximately four to eight seconds for a self-check when
the ignition switch is in the MAR/ACC/ON/RUN position. After
the self-check, the Air Bag Warning Light will turn off. If the ORC
detects a malfunction in any part of the system, it turns on the Air
Bag Warning Light, either momentarily or continuously. A single
chime will sound to alert you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnostics
also record the nature of the malfunction. While the air bag
system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.
• The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in the
MAR/ACC/ON/RUN position.
• The Air Bag Warning Light remains on after the four to eight-second interval.
• The Air Bag Warning Light comes on intermittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine related gauges
are not working, the Occupant Restraint Controller (ORC)
may also be disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an authorized
dealer service the air bag system immediately.

STARTING AND OPERATING 189
Consider the following items when computing the weight on
the rear axle of the vehicle:
• The tongue weight of the trailer.
• The weight of any other type of cargo or equipment put inor on your vehicle.
• The weight of the driver and all passengers.
NOTE:
Remember that everything put into or on the trailer adds to
the load on your vehicle. Also, additional factory-installed
options or dealer-installed options must be considered as
part of the total load on your vehicle. Refer to the “Tire And
Loading Information” placard for the maximum combined
weight of occupants and cargo for your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended.
Perform the maintenance listed in “Scheduled Servicing”.
Refer to “Scheduled Servicing” in “Servicing And Mainte -
nance” for the proper maintenance intervals. When towing a
trailer, never exceed the GAWR or GCWR ratings.
CAUTION!
Always load a trailer with 60% of the weight in the front
of the trailer. This places 10% of the GTW on the tow
hitch of your vehicle. Loads balanced over the wheels or
heavier in the rear can cause the trailer to sway severely
side to side which will cause loss of control of the vehicle
and trailer. Failure to load trailers heavier in front is the
cause of many trailer collisions.
CAUTION!
• Do not tow a trailer at all during the first 500 miles (805 km) the new vehicle is driven. The engine, axle or
other parts could be damaged.
• Then, during the first 500 miles (805 km) that a trailer is towed, do not drive over 50 mph (80 km/h) and do not
make starts at full throttle. This helps the engine and
other parts of the vehicle wear in at the heavier loads.
