NOTE:When having the Sentry Key System serviced,
bring all vehicle keys to the dealer.
Customer Key Programming
You can program new keys to the system if you have two
valid keys by doing the following:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds a chime
will sound and the Vehicle Theft Alarm Indicator Light
will begin to flash. Turn the ignition switch OFF and
remove the second key.4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds a single chime will sound and the Vehicle Theft
Alarm Indicator Light will stop flashing, turn on again
for 3 seconds, and then turn off.
The new Sentry Key has been programmed.The Keyless
Entry Transmitter will also be programmed during this
procedure.Repeat this procedure to program up to a
total of 8 keys. If you do not have a programmed sentry
key, contact your dealer for details.
NOTE:If a programmed key is lost, see your dealer to
have all remaining keys erased from the systems
memory. This will prevent the lost key from starting your
vehicle. The remaining keys must then be repro-
grammed. All vehicle keys must be taken to the dealer at
the time of service to be reprogrammed.

Buckle up even though you are an excellent driver, even
on short trips. Someone on the road may be a poor driver
and cause a collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save lives, and that
they can reduce the seriousness of injuries in a collision.
Some of the worst injuries happen when people are
thrown from the vehicle. Seat belts reduce the possibility
of ejection and the risk of injury caused by striking the
inside of the vehicle.Everyonein a motor vehicle should
be belted at all times.Lap/Shoulder Belts
All seating positions except the Quad Cab front center
seating position have combination lap/shoulder belts.
The belt webbing retractor is designed to lock during
very sudden stops or collisions. This feature allows the
shoulder part of the belt to move freely with you under
normal conditions. But in a collision, the belt will lock
and reduce the risk of your striking the inside of the
vehicle or being thrown out.

3. When the belt is long enough to fit, insert the latch
plate into the buckle until you hear a “click.”WARNING!
•A belt buckled into the wrong buckle will not protect you
properly. The lap portion could ride too high on your body,
possibly causing internal injuries. Always buckle your belt
into the buckle nearest you.
•A belt that is too loose will not protect you as well. In a
sudden stop you could move too far forward, increasing the
possibility of injury. Wear your seat belt snugly.
•A belt that is worn under your arm is very dangerous.
Your body could strike the inside surfaces of the vehicle in
a collision, increasing head and neck injury. And a belt
worn under the arm can cause internal injuries. Ribs aren’t
as strong as shoulder bones. Wear the belt over your
shoulder so that your strongest bones will take the force in
a collision.
•A shoulder belt placed behind will not protect you from
injury during a collision. You are more likely to hit your
head in a collision if you do not wear your shoulder belt.
The lap and shoulder belt are meant to be used together.

bags to inflate, it signals the inflators on the crash side of
the vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the side pillar molding out of the way and covers
the window. The airbag inflates in about 30 milliseconds
(about one-quarter of the time it takes to blink your eyes)
with enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the window bag inflates. This especially applies to
children. The window bag is only about 3
12inches (8.9
cm) thick when it is inflated.
NOTE:At no time should any supplemental restraint
system (SRS) component or SRS related component or
fastener be modified or replaced with any part except
those which are approved by DaimlerChrysler/Mopar.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position everyone for
the best interaction with the front airbag.
Enhanced Accident Response System
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 10 seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•If the belt still can’t be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the latch plate
around, and insert the latch plate into the buckle
again. If you still can’t make the child restraint secure,
try a different seating position.
•Buckle the child into the seat according to the child
restraint manufacturer’s directions.
•When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants or seat backs
and cause serious personal injury.
WARNING!
Improper installation can lead to failure of an infant
or child restraint. It could come loose in a collision.
The child could be badly injured or killed. Follow
the manufacturer’s directions exactly when installing
an infant or child restraint.

23. SERV 4WD Indicator
The 4WD indicator will be illuminated whenever the
4WD mode is engaged for either the manual or electric
shift 4WD systems. The SERV 4WD indicator monitors
the electric shift 4WD system. If the SERV 4WD light
stays on or comes on during driving, it means that the
4WD system is not functioning properly and that service
is required.
24. Water In Fuel Indicator
Indicates there is water detected in the fuel
filter. Refer to the Maintenance section, Drain-
ing Fuel/Water Separator Filter, for water
drain procedure. (See page 427 for more information.)
25. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only)
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It mayalso occur when operating the vehicle in a high torque
converter slip condition, such as 4-wheel-drive operation
(e.g. snow plowing, off- road operation). If this light
comes on, stop the vehicle and run the engine at idle or
faster, with the transmission in NEUTRAL until the light
goes off.
26. Wait To Start Indicator
The Wait To Start Indicator will illuminate when
the ignition is turned to the run position and the
intake manifold temperature is below 66 degrees F.
Follow engine starting procedure for proper engine start-
ing and operating. Wait until the Wait To Start Indicator
turns OFF then start the vehicle.
NOTE:The Wait To Start Indicator may not illuminate if
the engine coolant temperature is warm enough.

Stopping The Engine
Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine 3 to 5 minutes
before shutting it down. This idle period will allow the
lubricating oil and coolant to carry excess heat away from
the combustion chamber, bearings, internal components,
and turbocharger. This is especially important for turbo-
charged, charge air cooled engines.
NOTE:During engine shutdown on vehicles equipped
with manual transmissions, it is normal for the diesel
engine to resonate heavily for a moment during engine
shut off. When the engine is connected to a manual
transmission, this resonance causes load gear rattle from
the transmission. This is commonly referred to as “shut
down rattle”. The manufacturer recommends performing
engine shut down with the clutch pedal pushed to the
floor (clutch disengaged). When engine shut down is
performed in this manner the rattle is reduced (not
eliminated).Driving

Engine Speed Control
CAUTION!
Prevent overspeeding the engine going down hill.
When descending steep grades, use a combination of
gears and service brakes to control vehicle/engine
speed. Overspeed can cause severe engine damage.
Operating Precautions
Avoid Overheating The Engine
The temperature of the coolant (a mixture of 50%
ethylene-glycol and 50% water) must not exceed the
normal range of the temperature gauge (240°F/116°C)
with a 16 psi (110 kPa) radiator cap.
Usually the coolant temperature indicated during opera-
tion will be to the left of center in the normal range of the
gauge.
Avoid Low Coolant Temperature Operation
Continual operation at low coolant temperature below
the normal range on the gauge (140°F/60°C) can be
harmful to the engine. Low coolant temperature can
cause incomplete combustion which allows carbon and
varnish to form on piston rings and injector nozzles.
Also, the unburned fuel can enter the crankcase, diluting
the lubricating oil and causing rapid wear to the engine.
Cooling System Tips — Automatic Transmission
To reduce potential for engine and transmission over-
heating in high ambient temperature conditions, take the
following actions:
•City Driving —
when stopped, put transmission in neutral and increase
engine idle speed.
•Highway Driving —
reduce your speed.
