Four-Wheel-Drive Vehicles
Use the following procedure to dolly tow a
four-wheel-drive vehicle from the rear:
1. Attach the dolly to the tow vehicle following the
dolly manufacturer’s instructions.
2. Drive the rear wheels onto the dolly.
3. Firmly set the parking brake. SeeParking Brake on
page 3-30.
4. Put an automatic transmission in P (Park) or a
manual transmission in 1 (First).5. Secure the vehicle to the dolly following the
manufacturer’s instructions.
6. Use an adequate clamping device designed for
towing to ensure that the front wheels are locked
into the straight position.
{WARNING:
Shifting a full-time four-wheel-drive vehicle’s
transfer case into N (Neutral) can cause the
vehicle to roll even if the automatic transmission is
in P (Park) or the manual transmission is in any
gear. You or others could be injured. Make sure
the parking brake is firmly set before the transfer
case is shifted to N (Neutral).
7. Shift the transfer case to N (Neutral). See “Shifting
into N (Neutral)” underFour-Wheel Drive on
page 3-25.
8. Turn the ignition to LOCK/OFF.
If the vehicle being towed will not be started or
driven for six weeks or more, remove the battery
cable from the negative terminal (post) of the battery
to prevent the battery from draining.
After towing, see “Shifting Out of N (Neutral)” under
Four-Wheel Drive on page 3-25.

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
the engine oil and filter based on vehicle use. Whenever
the oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where the oil is changed prior to a CHANGE OIL
message being turned on, reset the system.
To reset the Engine Oil Life system:
1. With the engine off, turn the ignition to ON/RUN.
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.
If the CHANGE OIL message comes back on when the
vehicle is started, the engine oil life system has not
reset. Repeat the procedure. SeeDIC Warnings
and Messages on page 4-37.
What to Do with Used Oil
Used engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good hand
cleaner. Wash or properly dispose of clothing or rags
containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Recycle it by taking it to a
place that collects used oil.

Notice:If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlets. Turn off the
radio and all lamps that are not needed. This will
avoid sparks and help save both batteries. And it
could save the radio!
4. Open the hoods and locate the positive (+) and
negative (−) terminal locations on the other vehicle.
Your vehicle has a remote positive (+) and a remote
negative (−) jump starting terminal. SeeEngine
Compartment Overview on page 6-12for more
information on the terminal locations.
{WARNING:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the batteries have enough water. You do
not need to add water to the ACDelco
®battery
(or batteries) installed in your new vehicle. But if a
battery has filler caps, be sure the right amount of
fluid is there. If it is low, add water to take care of
that first. If you do not, explosive gas could be
present.
Battery fluid contains acid that can burn you.
Do not get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.

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 6-67for
additional information.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor
System (TPMS). The TPMS is designed to warn the
driver when a low tire pressure condition exists. TPMS
sensors are mounted onto each tire and wheel assembly
on your vehicle, excluding the spare tire. The TPMS
sensors monitor the air pressure in your vehicle’s tires
and transmit the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the low
tire pressure warning light
located on the instrument
panel cluster.
At the same time, a Driver Information Center (DIC)
message is displayed on the DIC display screen.
The low tire pressure warning light and the DIC warning
message come on at each ignition cycle until the tires are
inflated to the correct inflation pressure. For additional
information and details about the DIC operation and
displays seeDIC Operation and Displays on page 4-33
andDIC Warnings and Messages on page 4-37.
6-67
The low tire pressure warning light may come on in
cool weather when the vehicle is first 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 inflated 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 inflation pressure for
your vehicle’s tires when they are cold. SeeLoading the
Vehicle on page 5-33, for an example of the Tire and
Loading Information label and its location on your vehicle.
Also seeIn ation - Tire Pressure on page 6-64.
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 6-71andTires on page 6-57.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not covered
by your warranty. Do not use liquid tire sealants.TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
flashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until
the problem is corrected. Some of the conditions that
can cause the malfunction light and DIC message to
come on are:
•One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re-install the
road tire containing the TPMS sensor.
•The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicle’s tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See “TPMS Sensor Matching Process” later in this
section.
6-68
The TPMS sensor matching procedure is outlined
below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Turn the exterior lamp switch from AUTO to OFF
four times within three seconds. A double horn chirp
will sound and the TPMS low tire warning light starts
flashing. The double horn chirp and flashing TPMS
warning light indicates the TPMS matching process
has started. The TPMS warning light should continue
flashing throughout the matching procedure.
The LOW TIRE message displays on the Driver
Information Center (DIC).
4. Start with the driver side front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for 10 seconds,
then stop and listen for a single horn chirp. The
single horn chirp should sound within 15 seconds,
confirming that the sensor identification code has
been matched to this tire and wheel position. If you
do not hear the confirming single horn chirp, turn the
ignition switch to LOCK and start over beginning with
Step 2.6. Proceed to the passenger side front tire, and repeat
the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat
the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the
procedure in Step 5.
9. After hearing the confirming horn chirp for the driver
side rear tire, check to see if the TPMS low tire
warning light and the DIC LOW TIRE messages
have turned off. If yes, the TPMS sensors have been
relearned. Turn the ignition switch to LOCK/OFF.
If the low tire warning light and the SERV TPM
message on the DIC are on after completing Step 5
for the driver side rear tire, the sensor relearn
process has not been successful. Turn the ignition
switch to LOCK/OFF and repeat the matching
process beginning with Step 2.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.
