If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and the
parking brake is firmly set before you leave it. After you
move 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 first pulling it
toward you. If you can, it means that the shift lever
wasn't fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't 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 find it difficult to pull the
shift lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver's seat. To find out how, see ªShifting Into
PARK (P)º in the Index.
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).
Shifting Out of PARK (P)
(Automatic Transmission)
CAUTION:
Before shifting out of PARK (P) you must fully
apply your regular brakes. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. If you're pulling a trailer, see ªTowing a
Trailerº in the Index.
Your vehicle has a Brake-Transmission Shift Interlock
system (BTSI). You have to fully apply your regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. See ªAutomatic Transmissionº in
the Index.
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. Then,
move the shift lever to any gear you want.
If you ever hold the brake pedal down but still can't
shift out of PARK (P), try this:
1. Turn the key to OFF.

2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and shift to the drive gear you want.
5. Have the Brake
-Transmission Shift Interlock system
fixed as soon as you can.
Parking Your Vehicle
(Manual Transmission Only)
Before you get out of your vehicle, put your manual
transmission in REVERSE (R), turn off the engine, and
firmly apply the parking brake.
If you have four
-wheel-drive, be sure your transfer case
is in a drive gear. Your vehicle could roll if it isn't.
If you are parking on a hill, or if you are pulling a
trailer, see ªTowing a Trailerº in the Index.
CAUTION:
Shifting the transfer case to NEUTRAL (N) can
cause your vehicle to roll even if the manual
transmission is in gear. You or someone else could
be seriously injured. Be sure to set the parking
brake before placing the transfer case in
NEUTRAL (N). See ªParking Brakeº in the Index.
Parking Over Things That Burn
CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't park
over papers, leaves, dry grass or other things that
can burn.

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 firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Four-wheel drive vehicles with the transfer case in
NEUTRAL (N) will allow the vehicle 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 (N). Always
set your parking brake. Follow the proper steps to be
sure your vehicle won't move. See ªShifting Into
PARK (P)º in the Index.
If you're pulling a trailer, see ªTowing a Trailerº in
the Index.
Locking Rear Axle (If Equipped)
If you have this feature, your locking rear axle can give
you additional traction on snow, mud, ice, sand or
gravel. It works like a standard axle most of the time,
but when one of the rear wheels has no traction and the
other does, this feature will allow the wheel with
traction to move the vehicle.
Windows
Manual Windows
Turn the hand crank on each door to raise or lower
manual windows.

The driver's window also has an express-down feature
that allows the window to be lowered without holding
the switch. Press and hold the side of the window switch
marked AUTO for one second to activate the
express
-down mode. The express-down mode can be
canceled at any time by pressing the opposite side of the
switch. To open the window partway, lightly tap the
switch until the window is at the desired position.
Lockout Switch (Crew Cab)
If you have a Crew Cab and power windows, the power
window switch has a lockout feature. This feature
prevents the rear windows from operating when the
front driver's side switch is in LOCK. The windows can
still be operated using the driver's window switch.
When the switch is moved to NORM, the rear power
windows will operate again.
Swing-Out Windows (Extended Cab)
To open a rear swing-out
window, just flip the
latch open and swing
the glass out.
The latch will catch when the window is fully open and
will hold the window in the open position.
Sliding Rear Window (If Equipped)
To open the sliding rear window, unlock the latch lever
by moving the lever toward the front of the cab. Release
the lever from the latch plate and slide the window
toward the driver's side of the vehicle.
To close the window, slide the window toward the
passenger's side of the vehicle. The latch lever will
automatically snap locked on to the latch plate. Try to
open the window without releasing the latch lever to be
sure the window is in the locked position.

2-36 Turn Signal and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow
you to signal a turn or a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is finished, the lever will
return automatically.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.If you move the lever all the way up or down, and the
arrow flashes at twice the normal rate, a signal bulb
may be burned out and other drivers may not see your
turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check for burned
-out bulbs and a blown
fuse (see ªFuses and Circuit Breakersº in the Index).
Headlamp High/Low-Beam Changer
To change the headlamps from low to high beam or high
to low beam, pull the multifunction lever all the way
toward you. Then release it.
When the high beams
are on, this light on the
instrument panel also
will be on.

Compass Operation
Press the COMP switch once briefly to turn the compass
on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the compass heading.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause the
liquid cleaner to enter the mirror housing.
Compass Calibration
The compass may need calibration if:

After five seconds, the display does not show a
compass heading (ªNº for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item.

The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, the letter ªCº must be displayed in
the mirror compass windows. If ªCº is not displayed,push in the ªCOMPº button for approximately eight
seconds or until the letter ªCº is displayed.
The compass can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or

Drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.
Compass Variance
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, as during a long distance
cross
-country trip, it will be necessary to adjust for
compass variance. Compass variance is the difference
between earth's magnetic north and true geographic
north. If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance:
1. Press and hold the COMP button (located at the
bottom of the mirror) for three seconds until a zone
number appears in the display.
2. Find your current location and variance zone number
on the following zone map.

2-48 Camper-Type Outside Mirrors
(If Equipped)
If your vehicle is equipped with the camper-type
mirrors, they can be adjusted so you can have a clear
view of objects behind you.
1. To adjust the mirrors when hauling a slide-in camper
or towing a trailer, rotate the mirror by pushing the
mirror head toward the front of the vehicle.

2-50 Electric Outside Rearview Mirrors
(If Equipped)
Select the mirror you want
to move by moving the
center of the switch, located
on the driver's door armrest,
to L (left) or R (right).
Then, adjust the mirror angle by pressing the outer
arrows on the switch until the mirror is adjusted where
you want it.
Convex Outside Mirror
Your passenger's side mirror may be convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.
Storage Compartments
Your vehicle includes a number of storage
compartments for storage of often
-used items.
Some vehicles have storage areas in the instrument
panel. Use these spaces for items such as gloves or
small books.
Some models have a storage pocket on each of the
front doors.
Some vehicles have a storage area behind the seat.
Glove Box
To open your glove box, move the button toward the
passenger's side and pull the door open.
