Four-Wheel Drive
Transfer Case
When to Check Lubricant
Refer toMaintenance Schedule on
page 11-2 to determine when to
check the lubricant.
How to Check Lubricant
Active Transfer Case
A. Fill Plug
B. Drain Plug To get an accurate reading, the
vehicle should be on a level
surface.
If the level is below the bottom of
the fill plug (A) hole, some lubricant
will need to be added. Add enough
lubricant to raise the level to the
bottom of the fill plug (A) hole. Use
care not to overtighten the plug.
When to Change Lubricant
Refer to
Maintenance Schedule on
page 11-2 to determine how often to
change the lubricant.
What to Use
Refer to Recommended Fluids and
Lubricants on page 11-12 to
determine what kind of lubricant
to use.
Front Axle
When to Check and Change
Lubricant
It is not necessary to regularly
check front axle fluid unless a leak
is suspected, or an unusual noise is
heard. A fluid loss could indicate a
problem. Have it inspected and
repaired.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.

traction or performance as winter
tires on snow or ice-covered roads.
SeeWinter Tires on page 10-41.
Winter Tires
This vehicle was not originally
equipped with winter tires. Winter
tires are designed for increased
traction on snow and ice-covered
roads. Consider installing winter
tires on the vehicle if frequent
driving on snow or ice-covered
roads is expected. See your dealer
for details regarding winter tire
availability and proper tire selection.
Also, see Buying New Tires on
page 10-56.
With winter tires, there may be
decreased dry road traction,
increased road noise, and shorter
tread life. After changing to winter
tires, be alert for changes in vehicle
handling and braking.
If using winter tires:
.Use tires of the same brand and
tread type on all four wheel
positions.
.Use only radial ply tires of the
same size, load range, and
speed rating as the original
equipment tires.
Winter tires with the same speed
rating as the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
Summer Tires
This vehicle may come with high
performance summer tires. These
tires have a special tread and
compound that are optimized for
maximum dry and wet road
performance. This special tread and
compound will decrease
performance in cold climates, and
on ice and snow. We recommend
installing winter tires on the vehicle
if frequent driving in cold
temperatures or on snow or ice
covered roads is expected. See
Winter Tires on page 10-41.
All-Terrain Tires
This vehicle may have All-Terrain
Tires. These tires provide good
performance on most road surfaces,
weather conditions, and for off-road
driving. See Off-Road Driving on
page 9-5.
The tread pattern on these tires may
wear more quickly than other tires.
Consider rotating the tires more
frequently than at 12 000 km
(7,500 mi) intervals if irregular wear
is noted when the tires are
inspected. See Tire Inspection on
page 10-53.
Tire Sidewall Labeling
Useful information about a tire is
molded into the sidewall. The
examples show a typical
passenger and light truck tire
sidewall.

Vehicle Care 10-55
Warning (Continued)
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for New
Tires
Factors, such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. Some
commercial truck tires may not have
treadwear indicators. SeeTire
Inspection on page 10-53 andTire
Rotation on page 10-54 for
additional information.
The rubber in tires ages over time.
This also applies to the spare tire,
if the vehicle has one, even if it is
never used. Multiple factors
including temperatures, loading
conditions, and inflation pressure maintenance affect how fast aging
takes place. GM recommends that
tires, including the spare if
equipped, be replaced after six
years, regardless of tread wear. The
tire manufacturer date is the last
four digits of the DOT Tire
Identification Number (TIN) which is
molded into one side of the tire
sidewall. The first two digits
represent the week (01-52) and the
last two digits, the year. For
example, the third week of the year
2010 would have a four-digit DOT
date of 0310.
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle. Park
a vehicle that will be stored for at
least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be free
of grease, gasoline or other
substances that can deteriorate
rubber.

Warning (Continued)
tire service center repair or
replace the flat tire as soon as
possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road, if possible. Turn on the hazard
warning flashers. See
Hazard
Warning Flashers on page 6-5.
{Warning
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:
1. Set the parking brake firmly.
2. Put the shift lever in P (Park).
3. For vehicles with four-wheel-drive with a
N (Neutral) transfer case
position, be sure the
transfer case is in a drive
gear —not in N (Neutral).
4. Turn off the engine and do not restart while the vehicle
is raised.
(Continued)
Warning (Continued)
5. Do not allow passengers toremain in the vehicle.
6. Place wheel blocks on both sides of the tire at the
opposite corner of the tire
being changed.
When the vehicle has a flat tire (B),
use the following example as a
guide to assist in the placement of
the wheel blocks (A).

jack and wheel blocks from the
bracket.
4. Turn the wing nut retaining the wheel blocks (C)
counterclockwise to remove the
wheel blocks and the wheel
block retainer.
