The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
Your vehicle has Retained Accessory Power (RAP)
which allows certain features of your vehicle to
continue working for up to 20 minutes after
the ignition key is turned to LOCK.
The radio, front wipers, power windows, and a
sunroof if your vehicle has one, will work when the
ignition key is in ON or ACC. Once the key is turned
from ON to LOCK, these features continue working
for up to 20 minutes or until a door is opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position -- this is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
only when your vehicle is stopped.
Manual Transmission
The shift lever should be in the NEUTRAL position
and the parking brake engaged. Hold the clutch
pedal to the oor and start the engine. Your
vehicle will not start if the clutch pedal is not all
the way down. That is a safety feature.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as the engine gets warm. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently to allow the
oil to warm up and lubricate all moving parts.
103

Automatic Transmission Operation
The automatic transmission has a shift lever on
the console.
It features an electronic shift position indicator
within the instrument cluster. This display must be
powered anytime the shift lever is capable of
being moved out of PARK (P). This means that if
your key is turned off, but not in LOCK, there
will be a small current drain on your battery which
could discharge your battery over a period of
time. If you need to leave your key in the ignition
but not in LOCK for an extended period, it is
recommended that you disconnect the battery
cable from the battery to prevent discharging your
battery.
There are several different positions for your shift
lever.PARK (P):This position locks your rear wheels.
It is the best position to use when you start the
engine because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can
move suddenly. You or others could be
injured. To be sure your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake and
move the shift lever to PARK (P).
SeeShifting Into Park (P) (Automatic
Transmission) on page 117. If you are
pulling a trailer, seeTowing a Trailer on
page 297.
106

REVERSE (R):To back up, press the clutch pedal.
After the vehicle stops, shift into REVERSE (R).
Slowly let up on the clutch pedal as you press the
accelerator pedal. If it is hard to shift, let the shift
lever return to NEUTRAL and release the clutch
pedal. Then press the clutch again and shift into
REVERSE (R). Do not attempt to shift into the fth
gear position prior to shifting into REVERSE (R).
Your transmission has a lock out feature which
prevents a fth gear to reverse gear shift.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transmission. The repairs would not be covered
by your warranty. Shift to REVERSE (R) only
after your vehicle is stopped.
Use REVERSE (R), along with the parking brake,
for parking your vehicle.
Up-Shift Light
This light will show you
when to shift to the next
higher gear for best
fuel economy.When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions
permit. For the best fuel economy, accelerate
slowly and shift when the light comes on.
While you accelerate, it is normal for the light to
go on and off if you quickly change the position of
the accelerator. Ignore the shift light when you
downshift.
If your vehicle has four-wheel drive and has a
manual transmission, disregard the shift light when
the transfer case is in four-wheel low.
For more information, seeUp-Shift Light
(Manual Transmission) on page 181.
Shift Speeds
{CAUTION:
If you skip a gear when you downshift,
you could lose control of your vehicle.
You could injure yourself or others.
Do not shift down more than one gear
at a time when you downshift.
110

Press and release the Four-Wheel High or
Four-Wheel-High Lock button. If your vehicle has
a manual transmission, the clutch pedal must
be pressed to the oor while you press the
Four-Wheel High or Four-Wheel-High Lock
button, or the shift will not be completed.
You must wait for the Four-Wheel High or
Four-Wheel-High Lock indicator light to stop
ashing and remain lit before shifting your
transmission into gear.
It is normal for your vehicle to have engagement
noise and bump when shifting between
Four-Wheel Low and Four-Wheel High ranges
or from NEUTRAL with the engine running.
If the Four-Wheel High or Four-Wheel-High Lock
button is pressed when your vehicle is in gear
and/or moving too fast, the Four-Wheel High
or Four-Wheel-High Lock indicator light will ash
for 15 seconds but will not complete the shift
unless your vehicle is moving less than 3 mph
(5 km/h) and the transmission is in NEUTRAL (N).Shifting Into NEUTRAL
To shift the transfer case to NEUTRAL, do the
following:
1. Set the parking brake.
2. Start the vehicle by turning the ignition to
START.
3. Put the transmission in NEUTRAL (N).
If your vehicle has a manual transmission,
press and hold the clutch pedal down
while you perform Steps 5 through 9.
4. Shift the transfer case to Four-Wheel High.
{CAUTION:
Shifting an all-wheel-drive vehicle’s
transfer case into NEUTRAL can cause
your vehicle to roll even if the automatic
transmission is in PARK (P) or the manual
transmission is in any gear. You or others
could be injured. Make sure the parking
brake is rmly set before you shift the
transfer case to NEUTRAL.

clutch. This is to ensure the transfer case is
in NEUTRAL. If not, repeat this procedure
starting at Step 3.
7. Turn the engine off, by turning the key to ACC.
8. Place the transmission shift lever in PARK (P)
for an automatic transmission, or FIRST (1)
for vehicles that have a manual transmission.
9. Turn the ignition to LOCK.Shifting Out of NEUTRAL
To shift out of NEUTRAL:
1. Set the parking brake and apply the regular
brake pedal.
2. Shift the transmission to NEUTRAL (N) for an
automatic transmission, or press the clutch
pedal for vehicles that have a manual
transmission. Then turn the ignition to ON
with the engine off.
3. Press the button for the desired transfer
case shift position (Four-Wheel High,
Four-Wheel-High Lock or
Four-Wheel-Low Lock).
After the transfer case has shifted out of
NEUTRAL the light will go out.
4. Release the parking brake.
Notice:Shifting the transmission into gear
before the indicator light stops ashing could
cause damage to the transfer case. Always
wait until the indicator light stops ashing
before putting the transmission back in gear.
