2-10 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 housing near
the key ring hole. Remove the bottom by twisting
the object.

2. Remove and replace the battery, positive (+) side
down. Use one Panasonic
type CR2032 battery:
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.
See ªResynchronizationº following.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.

Switchbanks
Instrument Panel Switchbank
This switchbank is located in the center of the
instrument panel.
The switchbank may include marker lamp defeat, high
idle, traction control, heated mirrors, power take
-off,
rear air suspension, two
-speed axle (electric), exhaust
brake, two
-speed axle (air), differential lock, rear axle
differential lock and inter
-axle differential lock. If your
vehicle does not have some of the features controlled
by these switches, there will be a blank switch marker in
its place.
For more information, see each of these features in
the Index.

Theft
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.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
Remember to remove your key and take it with you.
Always do this. When you take your key with you,
your ignition will be locked. Also remember to lock
the doors.

2-15
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.

2-31
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.
CAUTION:
Be careful when using the exhaust brake or you
could lock the wheels and lose control of the
vehicle. Operators not familiar with an exhaust
brake should not use this brake on slippery
surfaces before learning to use it on dry surfaces.
If the vehicle's wheels begin to lock when using
the exhaust brake on slippery surfaces, switch the
exhaust brake off immediately. The exhaust
brake will turn off if the anti
-lock brake system
is activated.
Tw o-Speed Rear Axle Electric Shift
Control (If Equipped)
If your vehicle is equipped with this feature, you'll find
a label on the headliner above the windshield or in
another place near the driver that shows how to use it.
Be sure to follow the directions carefully.
Use the following directions based on the type of shift
control you have.
Manual Transmission
The rear axle shift control
switch for a manual
transmission is located
on the shift lever.
When the switch is up, the rear axle is in the high range.
Push the switch down to change to low range.

Tilt Wheel (If Equipped)
A tilt wheel allows you to adjust the steering wheel
before you drive. You can raise it to the highest level
to give your legs more room when you exit and enter
the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the wheel and pull the lever. Then
move the wheel to a comfortable position and release
the lever to lock the wheel in place.

Inter-Axle Differential Lock Control
(If Equipped)
If your vehicle has this
feature, the switch is located
in the center of the
instrument panel.

like one or even all of the wheels may start to slip, you
can press the bottom of this switch. It locks your rear
differentials so that power is transmitted equally to both
rear axles.Let up on the accelerator before you turn on your
inter
-axle differential lock. When you turn on this
control, the diff lock indicator on the center of the
instrument panel will light.

Activating the inter-axle differential lock when
the rear wheels are actually spinning freely, as
they might on ice or snow, can cause you to lose
control of the vehicle. It can also damage the
axles. Turn on this control only when the wheels
are not spinning freely.
