4n(Four-Wheel Low):This setting also engages the
front axle to give you extra traction. It sends the maximum
power to all four wheels. You might choose four-wheel
low if you were driving off-road in sand, mud, or deep
snow and while climbing or descending steep hills.
Shifting into Four-Wheel Low will turn Traction Control
and StabiliTrak
®off. SeeTraction Control System (TCS)
on page 5-8andStabiliTrak®System on page 5-6for
more information.
Indicator lights in the buttons show you which setting you
are in. The indicator lights will come on briefly when you
turn on the ignition and one will stay on the selected
setting. If the lights do not come on, you should take the
vehicle in for service. An indicator light will flash while
shifting. It will stay on when the shift is completed.
If the transfer case does not shift, it will return to the last
chosen setting.

The shift lock control system is designed to do the
following:
•Prevent the ignition key from being removed unless
the shift lever is in P (Park).
•Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN and the brake
pedal is applied.
The shift lock control system is always functional
except in the case of a dead battery or low voltage
(less than 9 V) battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 6-43for more information.
To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park):
1. Ease the pressure on the shift lever.
2. While holding down the brake pedal, push the shift
lever all the way into P (Park)
3. Move the shift lever to the desired position.
If you are still having a problem shifting, then have the
vehicle serviced.
Parking the Vehicle
(Manual Transmission)

out of the vehicle, move the shift lever into R (Reverse),
and firmly apply the parking brake. Once the shift
lever has been placed into R (Reverse) with the clutch
pedal pressed in, turn the ignition key to LOCK/OFF,
remove the key and release the clutch.
If you are parking on a hill, or if the vehicle is pulling a
trailer, seeTowing a Trailer on page 5-48.

Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check includes
the airbag sensor, the pretensioners, the airbag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 2-64.
The airbag readiness light
flashes for a few seconds
when the engine is started.
If the light does not come
on then, have it fixed
immediately.{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 4-37for
more information.

Passenger Airbag Status Indicator
If the vehicle has one of the passenger airbag status
indicators pictured in the following illustrations, then the
vehicle has a passenger sensing system for the right
front passenger position. The passenger airbag status
indicator is on the instrument panel. SeePassenger
Sensing System on page 2-73for important safety
information.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle’s sun visors refer to “ADVANCED
AIRBAGS”.
When the vehicle is started, the passenger airbag status
indicator will light ON and OFF, or the symbol for on and
off, for several seconds as a system check. Then, after
several more seconds, the status indicator will light either
ON or OFF, or either the on or off symbol to let you know
the status of the right front passenger frontal airbag.If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag is enabled (may inflate).
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger
frontal airbag.
If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be
a problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 4-22
for more information, including important safety
information. United States

The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 4-37for more
information. This light could indicate that there are

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into two
parts. If one part is not working, the other part can still
work and stop the vehicle. For good braking though,
both parts need to be working well.
If the warning light comes on, there could be a brake
problem. Have the brake system inspected right away.
This light comes on briefly when the ignition key is
turned to ON/RUN. If it does not, have it fixed so it will
be ready to warn if there is a problem.When the ignition is on, the brake system warning light
comes on when the parking brake is set. SeeParking
Brake on page 3-30for more information. The light stays
on if the parking brake does not release fully. If it stays on
after the parking brake is fully released, it means there is
a brake problem.
If the light comes on while driving, pull off the road and
stop. The brake pedal might be harder to push, or it
might go closer to the floor. It can take longer to stop.
If the light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 5-41.
{WARNING:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service. United StatesCanada

Antilock Brake System (ABS)
Warning Light
The Antilock Brake
System (ABS) light
comes on briefly when
the engine is started.

comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 4-25.
