At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
•Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
•Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
•Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
•If you are still having trouble, see your dealer or a
qualified technician for service.
Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 30 feet
(9 m) away using the remote keyless entry transmitter
supplied with your vehicle.
To unlock the driver’s door, press the UNLOCK button
one time. If you press the button again within five
seconds, all of the doors will unlock. When the UNLOCK
button is pressed, the interior dome lamps are turned
on for about 40 seconds or until the ignition switch
is activated. Press the LOCK button to lock all doors.

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.1. Insert a thin object, such as a coin, into the slot
between the covers of the transmitter near the
key ring hole. Remove the bottom by twisting
the object.
2. Remove and replace the battery. Use three-volt
type CR2032 battery (or equivalent).
3. Align the covers and snap them together.
4. Check the operation of the transmitter. If the
transmitter does not work after battery replacement,
it may need to be resynchronized to your vehicle.
SeeResynchronizationfollowing.

Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver. The
receiver will not respond to a signal it has been sent
previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and simultaneously press and hold the LOCK
and UNLOCK buttons on the transmitter for at least five
seconds. The door locks should cycle to confirm
resynchronization. If the locks do not cycle, see your
dealer for service.
Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.

Express-Down Feature
The driver’s window also has an express-down feature
that allows the window to be lowered without holding
down the switch. Press and hold the rear of the window
switch labeled AUTO for one second to activate the
express-down mode.
The express-down mode can be cancelled at any time
by pressing the front of the switch. To open the
window part way, lightly tap the switch until the window
is at the desired position.
Lockout Feature
If you have a crew cab model with power windows, the
driver’s door will have a window lockout feature.
When engaged, this feature will prevent all window
switches, except the driver’s window switches,
from operating. This switch is located above the four
window switches on the driver’s door. When the switch
is not engaged, all windows will return to normal
operation.
Sliding Rear Window
To open the sliding rear window, pull the latch 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 will
automatically lock into place. Try to open the window
without releasing the latch to be sure the window
is in the locked position.
Sun Visors
To block out glare, you can swing down the visors. You
can also swing them out to block glare from the side.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities,
and even commercial vehicles are no exception.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.

Ignition Positions
With your key in the ignition switch, you can turn it to
five different positions.
A (ACCESSORY):This position allows you to use
things like the radio, power windows and the windshield
wipers when the engine is off. To get into ACCESSORY,
push in the key and turn it toward you. Your steering
wheel will remain locked, just as it was before you
inserted the key.
B (LOCK):This position locks your ignition, steering
wheel and transmission. It’s a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.C (OFF):This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the
steering wheel like LOCK. Use OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being pushed).
D (RUN):This is the position for driving.
E (START):This position starts your engine.
Engine Starter Over-Crank Protection
Your vehicle may have an engine starter over-crank
protection system. If the starter motor overheats
and shuts off due to over-cranking, the motor must cool
down before it will reset and allow starter operation.
It can take up to six minutes before the starter will
work again.
Starting Your Gasoline Engine
Engines start differently. The 8th digit of your Vehicle
Identification Number (VIN) shows the code letter
for your engine. SeeVehicle Identi cation Number (VIN)
on page 5-85. Follow the proper steps to start the
engine.
To start a diesel engine, seeStarting Your Diesel
Engine on page 2-14.

Diesel Engine Exhaust Brake
The exhaust brake is available on vehicles equipped
with a diesel engine. It is located in the exhaust system.
The exhaust brake is used to help slow the vehicle
and may assist the vehicle’s foundation brakes. The use
of the exhaust brake will assist the braking of the
vehicle and prolong the life of the foundation brake
lining material.
The exhaust brake switch
is located in the instrument
panel switchbank.
Push the bottom of the switch to turn the exhaust brake
on. When you push the top of the switch, the exhaust
brake will turn off.There is an indicator light on the instrument panel
similar to the symbol on the switch, that will come on
when the exhaust brake is active. SeeExhaust
Brake Indicator Light on page 3-40for more information.
When using the exhaust brake, the proper gear range
selection is important. The exhaust brake will be
most effective if the gear range selected is the lowest
possible range that does not allow the engine rpm to go
more than 200 rpm above rated (full load) rpm. If you
have a Caterpillar
®diesel engine, do not exceed
2900 rpm. If you have a DURAMAX™ (LG4) diesel
engine, do not exceed 2400 rpm. If you have a
DURAMAX™ (LB7) diesel engine, do not exceed
3600 rpm.
If you have an automatic transmission and press this
button, the transmission will downshift to a factory
default setting of fourth gear. To change the default
setting, or for more information on factory default
settings, contact your dealer for assistance.
The accelerator and clutch pedals must be released in
order for the exhaust brake to engage. The exhaust
brake will not function when the cruise control feature is
active, and will automatically shut off when the
anti-lock brake system is active.

Outside Power Mirrors
If you have outside power mirrors, they can be adjusted
from the inside of the vehicle.
The control for this
feature is located on the
driver’s door.
Select the mirror you want to move by turning the
switch clockwise to adjust the passenger’s side mirror,
or counterclockwise to adjust the driver’s side mirror.
The center position is neutral.
Then, adjust the mirror by pressing the outer arrows on
the switch until the mirror is in the desired position.
Outside Convex Mirrors
Your vehicle has convex mirrors on the lower quarter of
both the driver’s and passenger’s side rearview
mirrors. 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 or left lane,
you could hit a vehicle. Check your regular
outside mirrors (or your inside mirror, if you
have one) before changing lanes.
