Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on the vehicle may damage the paint finish
and/or tires. When applying a tire dressing, always
wipe off any overspray from all painted surfaces on
the vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to parts repaired or
replaced to restore corrosion protection.
Original manufacturer replacement parts will provide
the corrosion protection while maintaining the
vehicle warranty.
Finish Damage
Any stone chips, fractures or deep scratches in the
finish should be repaired right away. Bare metal will
corrode quickly and may develop into major repair
expense.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer/retailer.
Larger areas of finish damage can be corrected in your
dealer's/retailer's body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are not
removed, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, floor pan,
and exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close areas
of the frame should be loosened before being flushed.
Your dealer/retailer or an underbody car washing
system can do this.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on the vehicle. This damage
can take two forms: blotchy, ring-shaped discolorations,
and small, irregular dark spots etched into the paint
surface.
Although no defect in the paint job causes this, we will
repair, at no charge to the owner, the surfaces of new
vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.

Maintenance Schedule
Introduction
This maintenance section applies to vehicles with a
gasoline engine. For diesel engine vehicles, see the
maintenance schedule section in the DURAMAX Diesel
manual.
Notice:Maintenance intervals, checks, inspections,
recommended fluids, and lubricants are necessary
to keep this vehicle in good working condition.
Damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Proper vehicle maintenance helps to keep the vehicle
in good working condition, improves fuel economy, and
reduces vehicle emissions for better air quality. Because of all the different ways people use vehicles,
maintenance needs vary. The vehicle might need
more frequent checks and services. Please read the
information under Scheduled Maintenance. To keep the
vehicle in good condition, see your dealer/retailer.
The maintenance schedule is for vehicles that:
.carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
See
Loading the Vehicle on page 5‑30.
.are driven on reasonable road surfaces within legal
driving limits.
.are driven off‐road in the recommended manner.
SeeOff-Road Driving on page 5‑11.
.use the recommended fuel. See Gasoline Octaneon page 6‑7.

When the Change Engine Oil Soon message
displays, certain services, checks, and inspections are
required. The services described for MaintenanceI
should be performed at every engine oil change.
The services described for Maintenance IIshould be
performed when:
.Maintenance Iwas performed the last time the
engine oil was changed.
.It has been 10 months or more since the Change
Engine Oil Soon message has displayed or since
the last service.
Maintenance I
.Change engine oil and filter. See Engine Oilon
page 6‑18. An Emission Control Service.
.Engine coolant level check. See Engine Coolanton page 6‑31.
.Windshield washer fluid level check. See
Windshield Washer Fluid on page 6‑38.
.Tire inflation check. SeeInflation - Tire Pressureon page 6‑72.
.Tire wear inspection. See Tire Inspection and
Rotation on page 6‑80.
.Rotate tires. See Tire Inspection and Rotationon
page 6‑80.
.Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system
must be repaired and the fluid level checked.
.Engine air cleaner filter inspection (vehicles
driven in dusty conditions only). See Engine Air
Cleaner/Filter on page 6‑21.
.Brake system inspection (or every 12 months,
whichever occurs first).
.For vehicles with Allison Transmission®only:
At the first engine oil change only, replace external
transmission filter.
Maintenance II
.Perform all services described in Maintenance I.
.Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts or
signs of wear.
.Lubricate the front suspension, steering linkage,
and parking brake cable guides. Control arm
ball joints on 2500/3500 series vehicles require
lubrication but should not be lubricated unless their
temperature is−12°C (10°F) or higher, or they
could be damaged. Control arm ball joints on
1500 series vehicles are maintenance‐free.
Vehicles used under severe commercial operating
conditions require lubrication on a regular basis
every 5 000 km/3,000 miles.

Once a Month
.Tire inflation check. SeeInflation - Tire Pressureon page 6‑72.
.Tire wear inspection. See Tire Inspection and
Rotation on page 6‑80.
Once a Year
.Starter switch check. See Owner Checks and
Services on page 7‑11.
.Parking brake and automatic transmission P (Park)
mechanism check. See Owner Checks and
Services on page 7‑11.
.Automatic transmission shiftlock control system
check. See Owner Checks and Serviceson
page 7‑11.
.Ignition transmission lock check. See Owner
Checks and Services on page 7‑11.
.Engine cooling system and pressure cap pressure
check. Radiator and air conditioning condenser
outside cleaning. See Cooling System
on
page 6‑30.
.Exhaust system and nearby heat shields
inspection for loose or damaged components.
.Accelerator pedal check for damage, high effort,
or binding. Replace if needed.
First Engine Oil Change After Every
40 000 km/25,000 Miles
.Fuel system inspection for damage or leaks.
.Four‐wheel drive only: Transfer case fluid change
(extreme duty service) for vehicles mainly driven
off‐road in four‐wheel drive. Vehicles used for
farming, mining, forestry, Department of Natural
Resources (DNR), and snow plowing occupations
meet this definition. Check vent hose at transfer
case for kinks and proper installation. Check to be
sure vent hose is unobstructed, clear, and free of
debris. During any maintenance, if a power washer
is used to clean mud and dirt from the underbody,
care should be taken to not directly spray the
transfer case output seals. High pressure water
can overcome the seals and contaminate the
transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and should
be replaced.

First Engine Oil Change After Every
80 000 km/50,000 Miles
.Engine air cleaner filter replacement. SeeEngine
Air Cleaner/Filter on page 6‑21.
.Automatic transmission fluid change (severe
service) for vehicles with Gross Vehicle Weight
Rating (GVWR) over 3 901 kg (8,600 lbs) or mainly
driven in heavy city traffic in hot weather, in hilly or
mountainous terrain, when frequently towing a
trailer, or used for taxi, police, or delivery service.
See Automatic Transmission Fluid (4-Speed
Transmission)
on page 6‑23or Automatic
Transmission Fluid (6-Speed Transmission)on
page 6‑26.
.Four‐wheel drive only: Transfer case fluid change
(severe service) for vehicles mainly driven when
frequently towing a trailer, or used for taxi, police,
or delivery service. Check vent hose at transfer
case for kinks and proper installation. Check to be
sure vent hose is unobstructed, clear, and free of
debris. During any maintenance, if a power washer is used to clean mud and dirt from the underbody,
care should be taken to not directly spray the
transfer case output seals. High pressure water
can overcome the seals and contaminate the
transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and should
be replaced.
.Evaporative control system inspection. Check all
fuel and vapor lines and hoses for proper hook‐up,
routing, and condition. Check that the purge valve,
if the vehicle has one, works properly. Replace as
needed.
An Emission Control Service. The U.S.
Environmental Protection Agency or the California
Air Resources Board has determined that the
failure to perform this maintenance item will not
nullify the emission warranty or limit recall liability
prior to the completion of the vehicle's useful life.
We, however, urge that all recommended
maintenance services be performed at the
indicated intervals and the maintenance be
recorded.
