A WORD ABOUT YOUR KEYS
The dealer that sold you your new vehicle has the key

be used to order duplicate keys from your dealer. Ask
your dealer for these numbers and keep them in a safe
place.

12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Manual Transmission—If Equipped
When the steering wheel is in the LOCK position, the
steering and ignition systems are locked to provide
antitheft protection for your vehicle. It may be difficult to
turn the key from the LOCK position when starting your
vehicle. Move the steering wheel left and right while
turning the key until it turns easily. To remove the key,
depress and hold the release button located between the
ignition switch and the instrument panel. Turn the igni-
tion key to LOCK and remove the key.
Locking Doors With The Key
You can insert the key with either side up. To lock the
door, turn the key rearward, to unlock the door, turn the
key forward. See Section 7 of this manual for door lock
lubrication.

14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

STEERING WHEEL LOCK — IF EQUIPPED
Your vehicle may be equipped with a passive steering
wheel lock. This lock prevents steering the vehicle with-
out the ignition key. If the steering wheel is moved no
more than 1/2 turn in either direction and the key is not
in the ignition switch, the steering wheel will lock.
If You Wish To Manually Lock The Steering
Wheel:
With the engine running, turn the steering wheel upside
down, turn off the engine and remove the key. Turn the
steering wheel slightly in either direction until the lock
engages.
To Release The Steering Wheel Lock:
Insert the key in the ignition switch and start the engine.
If the key is difficult to turn, move the wheel slightly to
the right or left to disengage the lock.
NOTE: If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ON positions, and the
brake pedal is depressed.
SENTRY KEY — IF EQUIPPED
The Sentry Key Immobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys, which have an embedded
electronic chip (transponder), to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate

•The lap portion should be low on the hips and as snug
as possible.
•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
NEW ENGINE BREAK-IN
Your Cummins 24 Valve Turbo Diesel engine does not
require a break-in period due to its construction. Normal
operation is allowed, provided the following recommen-
dations are followed:
NOTE: Light duty operation such as light trailer towing
or no load operation, will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
•Warm up the engine before placing it under load.
•Do not operate the engine at idle for prolonged
periods.
•Use the appropriate transmission gear to prevent
engine lugging.
•Observe vehicle oil pressure and temperature indica-
tors.
•Check the coolant and oil levels frequently.
•Vary throttle position at highway speeds when carry-
ing or towing significant weight.
Because of the construction of the Cummins Diesel
engine, engine run-in is enhanced by loaded operating
conditions which allow the engine parts to achieve final
finish and fit during the first 6,000 miles (10 000 km).

To decrease speed while the speed control is on, press
and hold the DECEL button. Release the button when the
desired speed is reached, and the new speed will be set.
To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE: When driving uphill, at elevations above 2,000
ft. (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. If the vehicle speed drops below 35 mph (56
km/h), the speed control will automatically disengage. If
this happens, you can push down on the accelerator
pedal to maintain the desired speed.
Vehicles equipped with a 6–speed manual transmission
should be operated in 4th or 5th gear under the above
conditions. Vehicles equipped with a 4–speed automatic transmis-
sion may exhibit several 4-3 downshifts under the above
conditions. To reduce the frequency of the downshifts
and to improve vehicle performance, it is advisable to
lock out overdrive by pressing the O/D OFF button
located at the end of the gear shifter.
WARNING!
Speed Control can be dangerous where the system
can’t maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control. An accident could be the result. Don’t use
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered, or slippery.

8. Return to the vehicle and firmlypress, hold for two
seconds and release the programmed HomeLink button.
Repeat the press/hold/release sequence a second time,
and, depending on the brand of the garage door opener
(or other rolling code equipped device), repeat this
sequence a third time to complete the programming.
HomeLink should now activate your rolling code
equipped device.
NOTE: To program the remaining two HomeLink but-
tons, begin with Programmingstep two. Do not repeat
step one . For questions or comments, please contact
HomeLink at www.homelink.com or 1-800-355-3515 .
Canadian Programming/Gate Programming
Canadian radio-frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of
transmission which may not be long enough for
HomeLink to pick up the signal during programming. Similar to this Canadian law, some U.S. gate operators are
designed to
time-outin the same manner.
If you live in Canada or you are having difficulties
programming a gate operator by using the Program-
ming  procedures (regardless of where you live), replace
 Programming HomeLink step 3 with the following:
NOTE: If programming a garage door opener or gate
operator, it is advised to unplug the device during the
 cycling process to prevent possible overheating.
3. Continue to press and hold the HomeLink button
while you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
successfully been accepted by HomeLink. (The indicator
light will flash slowly and then rapidly.) Proceed with
 Programming step four to complete.
