GETTING TO KNOW YOUR INSTRUMENT PANEL95
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 and can lead to tire failure. Underinflation
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 underinflation 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 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 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
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a
failure with the tow hook. Contact an
authorized dealer for service.
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.

Cruise Control Ready Indicator Light —
If Equipped With Base Instrument Cluster
This light will turn on when the Cruise
Control has been turned on, but not set
Úpage 117.
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II. This
system monitors the performance of the
emissions, engine, and automatic transmission
control systems. When these systems are
operating properly, your vehicle will provide
excellent performance and fuel economy, as well
as emissions well within current government
regulations.
If any of these systems require service, the OBD II
system will turn on the Malfunction Indicator Light
(MIL). It will also store diagnostic codes and other
information to assist your service technician in
making repairs. Although your vehicle will usually
be drivable and not need towing, see an authorized
dealer for service as soon as possible.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
C
YBERSECURITY

Your vehicle is required to have an OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may need
to access this information to assist with the
diagnosis and service of your vehicle and
emissions system Ú page 164.
CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
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, infor -
mation stored in your vehicle systems,
including personal information.

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
Maintenance (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.

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 position, 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 ignition 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 illuminated 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. If your OBD II system is
not ready, you should see
an authorized dealer or repair facility. If your
vehicle was recently serviced or had a battery
failure or replacement, you may need to do nothing
more than drive your vehicle as you normally would
in order for your OBD II system to update. A
recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system
is ready or not, if the MIL is illuminated during
normal vehicle operation you should have your
vehicle serviced before going to the I/M station.
The I/M station can fail your vehicle because the
MIL is on with the engine running.

104STARTING AND OPERATING
(Continued)
brake is fully disengaged, the Brake Warning Light
in the instrument cluster and the LED indicator on
the switch will extinguish.
NOTE:When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. Apply
the parking brake before placing the gear selector
in PARK, otherwise the load on the transmission
locking mechanism may make it difficult to move
the gear selector out of PARK. The parking brake
should always be applied whenever the driver is
not in the vehicle.
If exceptional circumstances should make it
necessary to engage the parking brake while the
vehicle is in motion, maintain upward pressure on
the EPB switch for as long as engagement is
desired. The BRAKE warning lamp will illuminate,
and a continuous chime will sound. The rear stop
lamps will also be illuminated automatically while
the vehicle remains in motion.
To disengage the parking brake while the vehicle is
in motion, release the switch. If the vehicle is
brought to a complete stop using the parking
brake, when the vehicle reaches approximately
3 mph, (5 km/h) the parking brake will remain
engaged.
WARNING!
Do not rely on the parking brake to operate
effectively if the rear brakes have been
immersed in water or mud.
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible injury
or damage.
When leaving the vehicle, always remove the
key fob from the ignition and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil
-
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter ’n Go™ in the ACC or ON/
RUN position. A child could operate power
windows, other controls, or move the vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle, or it may roll and cause
damage or injury. Also be certain to leave the
transmission in PARK. Failure to do so may
allow the vehicle to roll and cause damage or
injury.
WARNING!CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.
WARNING!
Driving the vehicle with the parking brake
engaged, or repeated use of the parking brake
to slow the vehicle, may cause serious damage
to the brake system. Be sure the parking brake
is fully disengaged before driving; failure to do
so can lead to brake failure and a collision.

STARTING AND OPERATING111
AUTOSTICK
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This feature can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
Operation
When the gear selector is in the AutoStick position
(beside the DRIVE (D) position), it can be moved
forward and rearward. This allows the driver to
manually select the transmission gear being used.
Moving the gear selector forward (-) triggers a
downshift and rearward (+) an upshift. The current
gear is displayed in the instrument cluster.
In AutoStick mode, the transmission will shift up or
down when the driver moves the gear selector
rearward (+) or forward (-), unless an engine
lugging or overspeed condition would result. It will
remain in the selected gear until another upshift or
downshift is chosen, except as described below.
6-speed transmissions will automatically
upshift when necessary to prevent engine
over-speed.
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans -
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear (or THIRD gear, in 6-speed
models, or in 4WD LOW, SNOW mode, or SAND
mode, where available). Tapping (+) (at a stop)
will allow starting in SECOND gear. Starting out
in SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.
NOTE:When Selec-Speed or Hill Descent Control is
enabled, AutoStick is not active.
To disengage AutoStick, return the gear selector to
the DRIVE position. You can shift in or out of the
AutoStick position at any time without taking your
foot off the accelerator pedal.
TRANSMISSION LIMP HOME MODE
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission may operate only in a fixed
gear, or may remain in NEUTRAL (N). The
Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode may allow the
vehicle to be driven to an authorized dealer for
service without damaging the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK (P), if possible. If not, shift the transmission to
NEUTRAL.
3. Push and hold the ignition until the engine turns off.
4. Wait approximately 30 seconds.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can reduce
the potential for overheating your engine by taking
the appropriate action.
On highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase engine
idle speed.
NOTE:There are steps that you can take to slow down an
impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off. The
A/C system adds heat to the engine cooling
system and turning the A/C off can help remove
this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and
aids in removing heat from the engine cooling
system.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.CAUTION!
Driving with a hot 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” and you hear
continuous chimes, turn the engine off
immediately and call for service.WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the
hood, do not open the hood until the radiator
has had time to cool. Never try to open a cooling
system pressure cap when the radiator or
coolant bottle is hot.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate in the
instrument cluster. This means that service is
required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow and
extremely hot or cold ambient temperatures will
influence when the “Change Oil” or “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú
page 77.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), one
year or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle
time is generally only a concern for fleet
customers.
NOTE:The Oil Change Indicator will not illuminate under
these conditions. Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for
unusual wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs before
the oil indicator system turns on.
Check the fluid levels of the coolant reservoir,
and brake master cylinder reservoir, and fill as
needed.
Check function of all interior and exterior lights.
