1-18 In Brief
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine
oil and filter.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN,with the engine off.
2. Press and release the stem in the lower center of the
instrument cluster until the
“Oil Life” message is displayed.
3. Once the alternating “Oil Life”
and “Reset” messages appear,
press and hold the stem
until several beeps sound.
This confirms that the oil life
system has been reset.
4. Turn the key to LOCK/OFF.
See Engine Oil Life System
on
page 10‑11.
Fuel E85 (85% Ethanol)
Vehicles that have the
5.3L V8 engine (Code P) have
a yellow fuel cap and can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
See Fuel E85 (85% Ethanol)
on
page 9‑66. In all other engines,
use only the unleaded gasoline
described under Recommended
Fuel on page 9‑64.
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving
tips to get the best fuel economy
possible.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for long
periods of time.
.When road and weather
conditions are appropriate, use
cruise control, if equipped.
.Always follow posted speed
limits or drive more slowly when
conditions require.
.Keep vehicle tires properly
inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
.Follow recommended scheduled
maintenance.

Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the oil
must be warm and the vehicle must
be on level ground.
The engine oil dipstick handle
is a yellow loop. See Engine
Compartment Overview
on
page 10‑6for the location of the
engine oil dipstick.
1. Turn off the engine and give the oil several minutes to drain back
into the oil pan. If this is not
done, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the tip
down, and check the level.
11-2 Service and Maintenance
.Are driven off-road in the
recommended manner. See
Off-Road Driving on page 9‑7.
.Use the recommended fuel.
SeeRecommended Fuelon
page 9‑64.
{WARNING
Performing maintenance work can
be dangerous. Some jobs can
cause serious injury. Perform
maintenance work only if you
have the required know-how and
the proper tools and equipment.
If in doubt, see your dealer to
have a qualified technician do
the work. See Doing Your Own
Service Work on page 10‑4.
At your dealer/retailer, you can be
certain that you will receive the
highest level of service available. Your dealer/retailer 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 in
Recommended Fluids
and Lubricantson page 11‑8and
Maintenance Replacement Partson
page 11‑10. We recommend the
use of genuine parts from your
dealer/retailer.
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
Rotation on page 10‑57.
Scheduled
Maintenance
When the Change Oil Message
Displays
Change engine oil and filter. See
Engine Oilon page 10‑9. An
Emission Control Service.
When the “Change Oil” 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
11-4 Service and Maintenance
.Windshield wiper blade
inspection for wear, cracking,
or contamination and windshield
and wiper blade cleaning,
if contaminated. SeeExterior
Care
on page 10‑92. Worn
or damaged wiper blade
replacement. See Wiper Blade
Replacement on page 10‑32.
.Body hinges and latches, key
lock cylinders, folding seat
hardware, and rear compartment
hinges, linkage, and handle
pivot points lubrication. See
Recommended Fluids and
Lubricants
on page 11‑8.
More frequent lubrication may
be required when vehicle
is exposed to a corrosive
environment. Applying silicone
grease on weatherstrips with a
clean cloth makes them last
longer, seal better, and not stick
or squeak.

First Engine Oil Change After
Every 80 000 km/50,000 Miles
.Engine air cleaner filter
replacement. See Engine Air
Cleaner/Filter on page 10‑17.
.Automatic transmission fluid
change (severe service) for
vehicles 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
on
page 10‑12.
.Four‐wheel drive only: Transfer
case fluid change. 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.
