Maintaining Your Airbag Systems
WARNING!
•Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper, vehicle body struc-
ture, or frame.
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.
Airbag Light
You will want to have the airbags ready to
inflate for your protection in an impact. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system promptly:
•The airbag light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
•The light remains on or flickers after the 6 to 8 second
interval.
•The light flickers or comes on and remains on while
driving.
NOTE:If the speedometer, tachometer or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready

nature, such as would identify a particular driver, ve-
hicle, or crash, will be treated confidentially. Confidential
data will not be disclosed by DaimlerChrysler Corpora-
tion to any third party except when:
1. Used for research purposes, such as to match data
with a particular crash record in an aggregate database,
provided confidentiality of personal data is thereafter
preserved
2. Used in defense of litigation involving a
DaimlerChrysler Corporation product
3. Requested by police under a legal warrant
4. Otherwise required by law
Data Parameters that May Be Recorded:
•Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
•Airbag disable lamp status (if equipped)
•Timeof airbag deployment (in terms of ignition
cycles and vehicle mileage)
•Airbag deployment level (if applicable)
•Seatbelt status
•Brake status (service and parking brakes)
•Accelerator status (including vehicle speed)
•Engine control status (including engine speed)
•Cruise control status
Child Restraint
Everyone in your vehicle needs to be buckled up all the
time — babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.

•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).

Exhaust Gas
WARNING!
Exhaust gases contain carbon monoxide, a poten-
tially toxic gas that by itself is colorless and odorless.
To avoid inhaling these gases, the following precau-
tions should be observed:
•Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
•If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into
the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
•The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system;
exhaust fumes detected inside the vehicle; or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
mispositioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust system
each time the vehicle is raised for lubrication or oil
change. Replace or adjust as required.

To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other abrasive materials to clean the lenses.
Daytime Running Lights (Canada Only and Fleet
Vehicles)
The headlights on your vehicle will illuminate when the
engine is started. This provides a constantLights ON
condition until the ignition is turned OFF. The lights
illuminate at less than 50% of normal intensity. If the
parking brake is applied the Daytime Running Lights
will turn off.
Lights-on Reminder
If the headlights, parking lights, or cargo lights are left
on, after the ignition is turned off, a chime will sound
when the driver’s door is opened.
Fog Lights — If Equipped
The foglights are turned ON by placing the head-
light rotary control in the parking light or head-
light position and pushing in the headlight rotary
control. The fog lights will operate only when the parking
lights are ON or when the vehicle headlights are ON low
beam. An indicator light located in the instrument cluster
will illuminate when the fog lights are on. The fog lights
will turn off when the switch is pushed a second time,
when the headlight switch is rotated to the OFF position,
or the high beam is selected.

NOTE:The default for the compass variance is zone 8.
To set the variance: Turn the ignition ON and set the
display to “Compass/Temperature.” Press and hold the
RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature, therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph (30
km/h) or during stop and go driving.

The outlet(s) has/have a fused direct feed from the
battery so it/they receive power whether the ignition is
ON or OFF.
All accessories connected to this/these outlet(s) should
be removed or turned OFF when the vehicle is not in use
to protect the battery against discharge.
NOTE:If desired, all of the power outlets can be
converted by your authorized dealer to provide power
with the ignition switch in the ON position only.CAUTION!
Electrical Outlet Use With Engine Off
•Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e. cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
•Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these inter-
mittently and with greater caution.
•After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.
