Ignition Positions
With the key in the ignition
switch, you can turn to four
different positions.
{CAUTION:
On manual transmission vehicles, turning the
key to LOCK will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to
turn the engine off while the vehicle is moving,
turn the key only to ACC. Do not push the key
in while the vehicle is moving.LOCK (A):This position locks your steering wheel,
ignition and transmission on automatic transmission
vehicles. If your vehicle has a manual transmission, this
position locks your steering wheel. It is a theft-deterrent
feature. You will only be able to remove your key
when the ignition is turned to LOCK.
If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the shift lever
is in PARK (P).
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
it is, turn the steering wheel left and right while you
turn the key hard. If none of this works, then
your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in which
you can operate your electrical accessories or items
plugged into the accessory power outlets. It also unlocks
the steering wheel and ignition. Use this position if
your vehicle must be pushed or towed.
2-17

4n(4LO):This setting also engages your front axle to
give you extra traction. It sends the maximum power
to all four wheels. You might choose 4LO if you
were driving off-road in sand, mud or deep snow and
climbing or descending steep hills.
Indicator lights in the buttons show you which setting
you are in. The indicator lights will come on briey when
you turn on the ignition and one will stay on. If the
lights do not come on, you should take your vehicle in
for service. An indicator light will ash while shifting.
It will remain illuminated when the shift is completed.
If for some reason the transfer case cannot make
a requested shift, it will return to the last chosen setting.
Shifting from 2HI to 4HI
Press and release the 4HI button. This can be done at
any speed, and the front axle will lock automatically.
Shifting from 4HI to 2HI
Press and release the 2HI button. This can be done at
any speed, and the front axle will unlock automatically.
Shifting from 2HI or 4HI to 4LO
To shift from 2HI or 4HI to 4LO, the vehicle must be
stopped or moving less than 1.2 mph (2 km/h) with the
transmission in NEUTRAL (N) in vehicles equipped
with an automatic transmission or the clutch pedal
engaged in vehicles equipped with a manual
transmission. The preferred method for shifting into
4LO is to have your vehicle moving 1.2 mph (2 km/h).
Press and release the 4LO button. You must wait for
the 4LO indicator light to stop ashing and remain
illuminated before shifting your transmission into gear or
releasing the clutch pedal.
If the 4LO button is pressed when your vehicle is in
gear and/or moving, the 4LO indicator light will ash for
30 seconds and not complete the shift.
On automatic transmission equipped vehicles, if your
transfer case does not shift into 4LO, your transmission
indicator switch may require adjustment. With your
transmission in NEUTRAL (N), press and release the
4LO button. While the 4LO indicator light is ashing, shift
your transmission into PARK (P). Press 4LO again.
Wait until the 4LO indicator light remains illuminated
before shifting your transmission into gear. Press
the 4LO button again to complete the shift. This will get
you into 4LO, but you should take your vehicle in for
service to restore normal operation.

Shifting from 4LO to 2HI or 4HI
To shift from 4LO to 2HI or 4HI, your vehicle must be
stopped or moving less than 1.2 mph (2 km/h) with
the transmission in NEUTRAL (N) or the clutch pedal
engaged. The preferred method for shifting out of 4LO
is to have your vehicle moving 1.2 mph (2 km/h).
Press and release the 4HI button. You must wait for
the 4HI indicator light to stop ashing and remain
illuminated before shifting your transmission into gear
or releasing the clutch pedal.
If the 4HI button is pressed when your vehicle is in gear
and/or moving, the 4HI indicator light will ash for
30 seconds but not complete the shift.
On vehicles with an automatic transmission, if your
transfer case does not shift into 4HI, your transmission
indicator switch may require adjustment. With your
transmission in NEUTRAL (N), press and release the
4HI button. While the 4HI indicator light is ashing, shift
your transmission into PARK (P). Wait until the 4HI
indicator light remains illuminated before shifting your
transmission into gear. Press the 4HI button again
to complete the shift. This will get you into 4HI, but you
should take your vehicle in for service to restore
normal operation.
Shifting to NEUTRAL
Use NEUTRAL when you plan to tow your vehicle.
SeeRecreational Vehicle Towing on page 4-47
for towing instructions. To shift the transfer case into
NEUTRAL, set the parking brake, then press and hold
the 2HI and the 4LO buttons at the same time for
10 seconds.
Shifting out of NEUTRAL
After towing your vehicle, you will have to shift out of
NEUTRAL in order to drive. To shift out of NEUTRAL,
do the following:
1. Set the parking brake and apply the regular brake
pedal. SeeParking Brake on page 2-29for more
information.
2. Start a vehicle with an automatic transmission in
PARK (P). Use FIRST (1) for vehicles with a
manual transmission.
3. Put an automatic transmission in NEUTRAL (N) or
press the clutch pedal for vehicles with a manual
transmission.
4. Press the button for the desired transfer case
position (2HI, 4HI or 4LO).
5. Shift the transmission to the desired gear. After the
transfer case has shifted out of NEUTRAL, the
indicator light will go out.
A re-engagement sound is normal when shifting out
of NEUTRAL.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
systems, seeAir Bag Systems on page 1-60.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should ash for a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it xed so it will
be ready to warn you if there is a problem.

{CAUTION:
If the air bag readiness light ever comes on

bag could inate even though the switch is off.
If this ever happens, do not let anyone whom
the national government has identied as a
member of a passenger air bag risk group sit
in the right front passenger’s position (for
example, do not secure a rear-facing child
restraint in the right front passenger’s seat)
until you have your vehicle serviced.
Battery Warning Light
This light will come on
briey when you start the
vehicle, as a check to
show you it is working;

may have a problem with the electrical charging system.
Have it checked right away. Driving while this light is
on could drain your battery and result in a vehicle that
may stall.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and climate control system.
