Be sure to perform the lubricant checks described in
this section. There are two additional systems that need
lubrication.
Transfer Case
When to Check Lubricant
Refer to the Maintenance Schedule to determine
how often to check the lubricant. SeeScheduled
Maintenance on page 6-4.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the ller plug hole,
you will need to add some lubricant. Add enough
lubricant to raise the level to the bottom of the ller
plug hole. Use care not to overtighten the plug.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-11. (A) Drain Plug (B) Filler Plug

Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in a crash, the
headlamp aim may be affected. Aim adjustment to the
low-beam headlamps may be necessary if oncoming
drivers ash their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be re-aimed, it is
recommended that you take the vehicle to your
dealer/retailer for service.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
or cracking. SeeScheduled Maintenance on page 6-4
for more information.
Replacement blades come in different types and are
removed in different ways. To replace the wiper
blade assembly, do the following:
1. Pull the windshield wiper arm away from the
windshield.
2. Press the button in the middle of the wiper arm
connector, and pull the wiper blade away from
the arm connector.
3. Install the new wiper blade, and make sure the
wiper blade locks into place.
For the proper size and type seeMaintenance
Replacement Parts on page 6-13.
Backglass Wiper Blade
1. Pull the wiper blade assembly away from the
backglass. The backglass wiper blade will not
lock in a vertical position, so care should be
used when pulling it away from the vehicle.
2. Rotate the wiper blade assembly, hold the wiper
arm in position and push the blade away from the
wiper arm.
3. Replace the wiper blade.
4. Return the wiper arm and blade assembly to the
rest position on the glass.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure readings
to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and in ated to the in ation
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire in ation pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in ation
pressure label, you should determine the proper
tire in ation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is signi cantly under-in ated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and in ate them to the proper pressure.
Driving on a signi cantly under-in ated tire causes the
tire to overheat and can lead to tire failure. Under-in ation
also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-in ation
has not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will ash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur
for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that
the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
SeeTire Pressure Monitor Operation on page 5-59for
additional information.

Using the DIC, tire pressure levels can be viewed by
the driver. For additional information and details
about the DIC operation and displays seeDIC Operation
and Displays (With DIC Buttons) on page 3-54orDIC
Operation and Displays (Without DIC Buttons) on
page 3-60andDIC Warnings and Messages on
page 3-64.
The low tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be in ated to the proper pressure.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s original
equipment tires and the correct in ation pressure for
your vehicle’s tires when they are cold. SeeLoading the
Vehicle on page 4-22, for an example of the Tire and
Loading Information label and its location on your vehicle.
Also seeInflation - Tire Pressure on page 5-56.Your vehicle’s TPMS can warn you about a low tire
pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 5-63andTires on page 5-49.
Notice:Using non-approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using
an incorrect tire sealant is not covered by the
vehicle warranty. Always use the GM approved
tire sealant available through your dealer/retailer.
Your vehicle, when new, may have included a
factory-installed Tire Sealant and Compressor Kit.
This kit uses a GM approved liquid tire sealant.
SeeTire Sealant and Compressor Kit on page 5-73.
