At your dealer, you can be certain that you will receive
the highest level of service available. Your dealer has
specially trained service technicians, uses genuine
replacement parts, as well as, up to date tools and
equipment to ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 7‑11andMaintenance Replacement Partson
page 7‑13. We recommend the use of genuine parts
from your dealer.
Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service
for new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). See Tire Inspection
and Rotation on page 6‑78.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑18. An Emission Control Service.
When the Change Engine Oil Soon message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than
a year. The engine oil and filter must be changed at
least once a year and the oil life system must be reset.
Your dealer has trained service technicians who will
perform this work and reset the system. If the engine
oil life system is reset accidentally, service the vehicle
within 5 000 km/3,000 miles since the last service.
Reset the oil life system whenever the oil is changed.
See Engine Oil Life System on page 6‑20.

When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
The services described for MaintenanceIshould 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 6‑32.
.Windshield washer fluid level check.
SeeWindshield Washer Fluid on page 6‑41.
.Tire inflation check. See Inflation - Tire Pressureon page 6‑72.
.Tire wear inspection. See Tire Inspection and
Rotation on page 6‑78.
.Rotate tires. See Tire Inspection and Rotationon
page 6‑78.
.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 6‑22.
.Brake system inspection (or every 12 months,
whichever occurs first).
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 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.
.Engine cooling system inspection. Visual
inspection of hoses, pipes, fittings, and clamps
and replacement, if needed.
7-4
.Automatic transmission shiftlock control system
check. SeeOwner Checks and Serviceson
page 7‑9.
.Ignition transmission lock check. See Owner
Checks and Services on page 7‑9.
.Hood and liftgate gas strut support service.
Visually inspect gas strut for signs of wear,
corrosion, cracks, loss of lubricant, or other
damage. Check the hold open ability of gas strut.
Replace as necessary with genuine parts from
your dealer.
.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.
First Engine Oil Change After Every
80 000 km/50,000 Miles
.Engine air cleaner filter replacement. See Engine
Air Cleaner/Filter on page 6‑22.
.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 6‑24or Automatic
Transmission Fluid (6-Speed Transmission)on
page 6‑27.
.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.
7-6
.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.
First Engine Oil Change After Every
160 000 km/100,000 Miles
.Automatic transmission fluid change (normal
service). See Automatic Transmission Fluid
(4-Speed Transmission)
on page 6‑24or
Automatic Transmission Fluid (6-Speed
Transmission) on page 6‑27.
.Four‐wheel drive only: Transfer case fluid change
(normal 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.
.Spark plug replacement and spark plug wires
inspection. An Emission Control Service.
First Engine Oil Change After Every
240 000 km/150,000 Miles
.Engine cooling system drain, flush, and refill,
cooling system and cap pressure check, and
cleaning of outside of radiator and air conditioning
condenser (or every 5 years, whichever occurs
first). SeeEngine Coolant
on page 6‑32.
An Emission Control Service.
.Engine accessory drive belt inspection for fraying,
excessive cracks, or obvious damage and
replacement, if needed. An Emission Control
Service.
