SERVICING AND MAINTENANCE
SCHEDULED SERVICING
3.6L AND 5.7L ENGINES
These vehicles are equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent short-trips,
trailer tow, and extremely hot or cold ambient
temperatures will influence when the “Change Oil”
or “Oil Change Required” message is displayed.
Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
The “Oil Change Required” message will be
displayed in the instrument cluster and a single
chime will sound, indicating that an oil change is
necessary. An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to “Instrument
Cluster Display” Ú
page 69.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for fleet
customers.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check tire pressure and look for unusual wear
or damage. Rotate tires at the first sign of irreg -
ular wear, even if it occurs before your next
scheduled service.
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering (if
equipped) and fill as needed.
Check function of all interior and exterior lights.
Maintenance Plan — 3.6L And 5.7L

TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect
thestability of the vehicle and can produce a
feeling of sluggish response or over
responsiveness in the steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption. Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
ride. Overinflation produces a jarring and
uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on
the driver's side B-pillar or rear edge of the driver's
side door.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly inflated
even when they are underinflated.
Inspect tires for signs of tire wear or visible
damage.
WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and can
result in overheating and tire failure.
Overinflation reduces a tire's ability to cushion
shock. Objects on the road and chuckholes
can cause damage that result in tire failure.
Overinflated or underinflated tires can affect
vehicle handling and can fail suddenly,
resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle to
drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation p ressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.

22_LD_OM_EN_USC_t.book Page 273
276SERVICING AND MAINTENANCE
NOTE:Wheel valve stem must be replaced as well when
installing new tires due to wear and tear in existing
tires.
Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed Úpage 275. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
See the Tire Sizing Chart example found in the “Tire
Safety Information” section of this manual for
more information relating to the Load Index and
Speed Symbol of a tire Ú page 264.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels. It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
TIRE TYPES
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Traction
levels may vary between different all season tires.
All season tires can be identified by the M+S, M&S,
M/S or MS designation on the tire sidewall. Use all
season tires only in sets of four; failure to do so
may adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in
snow or on ice. If your vehicle is equipped with
Summer tires, be aware these tires are not
designed for Winter or cold driving conditions.
Install Winter tires on your vehicle when ambient
temperatures are less than 40°F (5°C) or if roads
are covered with ice or snow. For more
information, contact an authorized dealer.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for your
vehicle. Some combinations of unapproved
tires and wheels may change suspension
dimensions and performance characteristics,
resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpre
-
dictable handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire over -
loading and failure. You could lose control and
have a collision.
Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different
size may result in false speedometer and
odometer readings.

TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles
operate at different loads and perform different
steering, driving, and braking functions. For these
reasons, they wear at unequal rates.
These effects can be reduced by timely rotation of
tires. The benefits of rotation are especially
worthwhile with aggressive tread designs such as
those on all season type tires. Rotation will
increase tread life, help to maintain mud, snow
and wet traction levels, and contribute to a
smooth, quiet ride.
For the proper maintenance intervals Úpage 234.
The reasons for any rapid or unusual wear should
be corrected prior to rotation being performed. The suggested rotation method is the “rearward
cross” shown in the following diagram. This
rotation pattern does not apply to some directional
tires that must not be reversed.
Tire Rotation (Rearward Cross)
DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can cause
unpredictable handling. You could lose control
and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe
the following precautions:
Because of restricted traction device clearance
between tires and other suspension compo -
nents, it is important that only traction devices
in good condition are used. Broken devices can
cause serious damage. Stop the vehicle imme -
diately if noise occurs that could indicate device
breakage. Remove the damaged parts of the
device before further use.
Install device as tightly as possible and then
retighten after driving about ½ mile (0.8 km).
Autosock traction devices do not require
retightening.
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns and
large bumps, especially with a loaded vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed of
the device manufacturer’s if it is less than
30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION!
