Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing
its job. See your dealer/retailer to have it repaired. Torn
or frayed safety belts may not protect you in a crash.
They can rip apart under impact forces. If a belt is torn
or frayed, get a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 3-26for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-100.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-27for more information.
Notice:If an airbag covering is damaged, opened,
or broken, the airbag may not work properly.
Do not open or break the airbag coverings. If there
are any opened or broken airbag covers, have
the airbag covering and/or airbag module replaced.
For the location of the airbag modules, seeWhat
Makes an Airbag Inflate? on page 1-64. See
your dealer/retailer for service.
1-78

A reading in the low pressure zone may be caused by
a dangerously low oil level or other problem causing low
oil pressure. Check your oil as soon as possible.
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

Average Speed
Press the trip/fuel button until AVERAGE SPEED
displays. This display shows the average speed of
the vehicle in miles per hour (mph) or kilometers per
hour (km/h). This average is calculated based on
the various vehicle speeds recorded since the last
reset of this value. To reset the value, press and hold
the set/reset button. The display will return to zero.

through the following menu items:
Oil Life
Press the vehicle information button until OIL LIFE
REMAINING displays. This display shows an estimate of
the oil’s remaining useful life. If you see 99% OIL LIFE
REMAINING on the display, that means 99% of the
current oil life remains. The engine oil life system will alert
you to change the oil on a schedule consistent with your
driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the
display. See “CHANGE ENGINE OIL SOON” under
DIC Warnings and Messages on page 3-48. You should
change the oil as soon as possible. SeeEngine Oil
on page 5-15. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be careful not
to reset the OIL LIFE accidentally at any time other than
when the oil has just been changed. It cannot be reset
accurately until the next oil change. To reset the engine
oil life system, seeEngine Oil Life System on page 5-18.

System (TPMS), this message displays when the
pressure in one or more of the vehicle’s tires needs to
be checked. This message also displays LEFT FRONT,
RIGHT FRONT, LEFT REAR, or RIGHT REAR to
indicate which tire needs to be checked. You can receive
more than one tire pressure message at a time. To read
the other messages that may have been sent at the same
time, press the set/reset button. If a tire pressure
message appears on the DIC, stop as soon as you can.
Have the tire pressures checked and set to those shown
on the Tire Loading Information label. SeeTires on
page 5-54,Loading the Vehicle on page 4-19, and
Inflation - Tire Pressure on page 5-62. The DIC also
shows the tire pressure values. SeeDIC Operation

Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
•start the engine,
•shift into a gear, and
•release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See this manual’s Maintenance Schedule
or Index for more information. Things that are especially
important in trailer operation are automatic transmission
fluid, engine oil, axle lubricant, belts, cooling system
and brake system. It is a good idea to inspect
these before and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
The optional heavy-duty trailer wiring package includes
a wiring harness, with a seven-pin connector at the
rear of the vehicle and a four-wire harness assembly
under the driver side of the instrument panel. The
four-wire harness assembly comes without a connector.
If the vehicle does not have a trailer hitch, the
seven-wire harness assembly with connector is taped
together and located in a frame pocket at the driver side
rear left corner of the frame.
If the vehicle has a trailer hitch, the seven-wire harness
assembly with connector is attached to a bracket on
the hitch platform. In both cases, the seven-wire harness
has a connector and includes a 30-amp feed wire.

Engine Air Cleaner/Filter
If your vehicle has the DURAMAX Diesel engine, see
the DURAMAX Diesel manual for more information.
The engine air cleaner/filter is located near the center of
the engine compartment. SeeEngine Compartment
Overview on page 5-14for more information on location.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the MaintenanceII
intervals and replace it at the first oil change after each
50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 6-4for more information. If you are
driving in dusty/dirty conditions, inspect the filter at each
engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter, remove the filter from
the vehicle and lightly shake the filter to release loose
dust and dirt. If the filter remains caked with dirt, a new
filter is required. Never use compressed air to clean
the filter.
To inspect or replace the engine air cleaner/filter, do the
following:
1. Unhook the retainer clips and remove the cover.
2. Lift the filter out of the engine air cleaner/filter
housing. Care should be taken to dislodge as
little dirt as possible.

How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. SeeRecommended
Fluids and Lubricants on page 6-13.
Using a funnel, add fluid down the transmission dipstick
tube only after checking the transmission fluid while
it is hot. A cold check is used only as a reference. If the
fluid level is low, add only enough of the proper fluid
to bring the level up to the HOT area for a hot check.
It does not take much fluid, generally less than
one pint (0.5 L). Do not overfill.
Notice:Use of the incorrect automatic transmission
uid may damage the vehicle, and the damages
may not be covered by the vehicle’s warranty.
Always use the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 6-13.
•After adding fluid, recheck the fluid level as described
under “How to Check Automatic Transmission Fluid,”
earlier in this section.
•When the correct fluid level is obtained, push the
dipstick back in all the way; then flip the handle down
to lock the dipstick in place.
Cooling System
If your vehicle has a diesel engine, see “Van Models”
under “Cooling System” in the DURAMAX®Diesel
Supplement.
The Cooling System allows the engine to maintain the
correct working temperature.
A. Radiator Pressure Cap
B. Coolant Recovery Tank
C. Engine Cooling Fan(s)
