Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle
could move suddenly if the shift lever is
not fully in PARK (P) with the parking
brake rmly set. And, if you leave the
vehicle with the engine running, it could
overheat and even catch re. You or
others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. After you have moved the shift lever
into PARK (P), hold the regular brake pedal down.
Then, see if you can move the shift lever away
from PARK (P) without rst pulling it toward you.
If you can, it means that the shift lever was
not fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift
your transmission into PARK (P) properly,
the weight of the vehicle may put too much
force on the parking pawl in the transmission.
You may nd it difficult to pull the shift lever out
of PARK (P). This is called torque lock. To prevent
torque lock, set the parking brake and then shift
into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into
Park (P) (Automatic Transmission) on page 135.
When you are ready to drive, move the shift
lever out of PARK (P) before you release the
parking brake.
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, so you can pull the shift
lever out of PARK (P).
136

Shifting Out of Park (P)
(Automatic Transmission)
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
position. In addition, you have to fully apply the
regular brakes before you can shift from PARK (P)
when the ignition is in ON. SeeAutomatic
Transmission Operation on page 124.
If you cannot shift out of PARK (P), ease pressure
on the shift lever by pushing the shift lever all
the way into PARK (P) as you maintain brake
application. Then, move the shift lever into
the gear you want.
If you ever hold the brake pedal down but still
cannot shift out of PARK (P), try this:
1. Turn the key to ACC. There is no shift
interlock in this key position.
2. Apply and hold the brake until the end of
Step 4.3. Shift the transmission to NEUTRAL (N).
4. Start the vehicle and then shift to the gear
you want.
5. Have the system xed as soon as you can.
Parking Your Vehicle
(Manual Transmission)
Your vehicle has a manual transmission.
Before you get out of your vehicle, move the
shift lever into REVERSE (R), and rmly apply
the parking brake. Once the shift lever has
been placed into REVERSE (R) with the clutch
pedal pressed in, turn the ignition key to LOCK,
remove the key and release the clutch.
If you are parking on a hill, or if your vehicle is
pulling a trailer, seeTowing a Trailer on page 306.

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 139.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is
at the highest setting. One place this
can happen is a garage. Exhaust — with
CO — can come in easily. NEVER park
in a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 286.
{CAUTION:
It can be dangerous to get out of your
vehicle if the automatic transmission 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 it is on fairly
level ground, always set the parking brake
and move the automatic transmission
shift lever to PARK (P), or the manual
transmission shift lever to NEUTRAL.
140

{CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to
roll, even if the automatic transmission
shift lever is in PARK (P). So, be sure the
transfer case is in a drive gear — not in
NEUTRAL. Always set the parking brake.
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P)
(Automatic Transmission) on page 135.
If you are pulling a trailer, seeTowing a Trailer
on page 306.
Mirrors
Manual Rearview Mirror
While sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind
your vehicle. Grip the mirror in the center to move
it up or down and side to side. The control at
the bottom of the mirror is the day/night feature
that allows adjustment to the mirror so that
the glare of headlamps from behind is reduced.
Push the control for daytime use; pull it for
night use.

Move the cruise lever from on to resume/
accelerate. Hold it there until you get up to the
speed desired, and then release the lever.
To increase your speed in very small amounts,
move the lever briey to resume/accelerate.
Reducing Speed While Using
Cruise Control

Press and hold the set button until you reach
the lower speed desired, then release it.
To slow down in very small amounts, briey
press the set button.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle
speed. When you take your foot off the pedal,
the vehicle will slow down to the cruise control
speed you set earlier.
Using Cruise Control on Hills
How well the cruise control will work on hills
depends upon the vehicle speed, load, and the
steepness of the hills. When going up steep hills,
you might want to step on the accelerator
pedal to maintain the vehicle speed. When going
downhill, you might have to brake or shift to a
lower gear to keep the vehicle speed down.
Of course, applying the brake turns off the cruise
control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
To turn off the cruise control, do one of the following:
Step lightly on the brake pedal.
Move the cruise control lever to off.
Lightly tap or press the clutch, if you have a
manual transmission.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
the cruise control set speed memory is erased.

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) if you
have an automatic transmission.
The light sensor determines it is daytime.
Your vehicle will have either the parking lamps or
reduced intensity low beams used as the DRL.
When the DRL are on, only those lamps will be on.
The taillamps, sidemarkers, and other lamps will
not be on. The instrument panel will not be lit
up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular
headlamps.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on after the
transmission has been shifted from PARK (P) to
DRIVE (D). The headlamps, taillamps, sidemarker,
parking lamps, roof marker lamps, and the
instrument panel lights will turn on at normal
brightness. The radio lights will become more dim
when the headlights are off compared to when
the headlights are on.
Your vehicle has a light sensor located on the
top of the instrument panel. Be sure it is not
covered, or the system will be 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.
