Shifting Into Park (P)
{CAUTION:
It can be 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. 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, use
the steps that follow. With four-wheel drive,
if your transfer case is in NEUTRAL, your
vehicle will be free to roll, even if your shift
lever is in PARK (P). So, be sure the
transfer case is in a drive gear — not in
NEUTRAL. If you are pulling a trailer, see
Towing a Trailer on page 422.1. Hold the brake pedal down with your right foot
and set the parking brake.
2. Move the shift lever into the PARK (P)
position by pulling the shift lever toward
you and moving it up as far as it will go.
3. Be sure the transfer case is in a drive
gear — not in NEUTRAL (N).
4. Turn the ignition key to LOCK.
5. Remove the key and take it with you. If you
can leave your vehicle with the ignition key in
your hand, your vehicle is in PARK (P).
157

If torque lock does occur, you may need to have
another vehicle push yours a little uphill to
take some of the pressure from the parking pawl
in the transmission, then you will be able to
pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system which locks the shift lever
in PARK (P) when the ignition is in the LOCK. You
have to fully apply your regular brakes before
you can shift from PARK (P) when the ignition is
in RUN. SeeAutomatic Transmission Operation on
page 145.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the
way up into PARK (P) as you maintain brake
application. Move the shift lever into another gear.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves, dry
grass, or other things that can burn.

passenger’s and/or driver’s mirror to tilt to a
preselected position when the vehicle is in
REVERSE (R).
The passenger’s and/or driver’s mirror will return to
its original position when the vehicle is shifted out of
REVERSE (R) and either a thirty second delay has
occurred, the vehicle speed is greater than 8 mph
(12 km/h), or the ignition is turned to off.
This feature can be turned on or off through the
Driver Information Center (DIC). SeeDriver
Information Center (DIC) on page 260for more
information.

Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close the sunroof, the ignition
needs to be turned to ON, or Retained Accessory
Power (RAP) must be active. When RAP is active,
the sunroof will work for 10 minutes after the
ignition is turned off, or until a front door is opened.

Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the
steering wheel until the desired lower speed is
reached, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time you do this, the vehicle will
go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your
vehicle will slow down to the previous set cruise
speed.
Using Cruise Control on Hills
How well your cruise control will work on hills
depends upon your speed, load, and the
steepness of the hills. When going up steep hills,
you may have to step on the accelerator pedal
to maintain the vehicle’s speed. When going
downhill, you may have to brake or shift to a lower
gear to keep the vehicle’s speed down. Of
course, applying the brake takes you out of cruise
control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the cancel button on the steering wheel.
Press the On/Off button on the steering
wheel.
Erasing Speed Memory
When you turn off the cruise control or the
ignition, the cruise control set speed memory is
erased.

control is located on the
instrument panel to
the left of the steering
wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
The exterior lamps control has four positions:
9(Off):Turn the control to this position to turn
off the automatic headlamps and daytime
running lamps (DRL). Turning the headlamp
control to the off position again will turn the
automatic headlamps or DRL back on.
For vehicles rst sold in Canada, the off position
will only work for vehicles that are shifted into
the PARK (P) position.AUTO (Automatic):Turn the control to this
position to automatically turn on the headlamps at

while the vehicle is off, the headlamps will continue
to stay on. Turn the control to the off position to
turn the headlamps off or the battery will be
drained.
215

Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
Headlamps on Reminder
A reminder chime will sound when the headlamps
or parking lamps are manually turned on and
your ignition is off and a door is open. To disable
the chime, turn the light off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional daytime running lamps
are required on all vehicles rst sold in Canada.The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only your DRL lamps will
be on. The taillamps, sidemarker, and other lamps
will not be on. The instrument panel will not be
lit up either.
When it begins to get dark, the automatic
headlamp system will switch from DRL to the
headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release.
For vehicles rst sold in Canada, the transaxle
must be in the PARK (P) position, before the DRL
lamps can be turned off.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
216

Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on the headlamps at the
normal brightness, along with the taillamps,
sidemarker, parking lamps, and the instrument
panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position
and then release. For vehicles rst sold in Canada,
the transaxle must be in the PARK (P) position,
before the automatic headlamp system can
be turned off.
The vehicle has a light sensor located on the top
of the instrument panel in the defroster grille
that regulates when the automatic headlamps turn
on. Be sure it is not covered, or the headlamps
will come on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.There is a delay in the transition between the
daytime and nighttime operation of the Daytime
Running Lamps (DRL) and the automatic headlamp
systems so that driving under bridges or bright
overhead street lights does not affect the system.
The DRL and automatic headlamp system will only
be affected when the light sensor detects a change
in lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately one minute for the automatic
headlamp system to change to DRL if it is
bright enough outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 219.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 280.
As with any vehicle, you should turn on the regular
headlamp system when needed.
