Towing a Trailer
{WARNING:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well—or
even at all. The driver and passengers could
be seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer for advice and information about
towing a trailer with the vehicle.
Notice: Pulling a trailer improperly can damage the
vehicle and result in costly repairs not covered by
the vehicle warranty. To pull a trailer correctly,
follow the advice in this section and see your dealer
for important information about towing a trailer with
the vehicle. The vehicle can tow a trailer if it is equipped with
the proper trailer towing equipment. To identify the
trailering capacity of the vehicle, read the information
in
“Weight of the Trailer” that appears later in this
section. Trailering is different than just driving the
vehicle by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment,
and it has to be used properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of
these are important for the safety of the driver and
the passengers. So please read this section carefully
before pulling a trailer.
Load-pulling components such as the engine,
transmission, axles, wheel assemblies and tires are
forced to work harder against the drag of the added
weight. The engine is required to operate at relatively
higher speeds and under greater loads, generating
extra heat. The trailer also adds considerably to wind
resistance, increasing the pulling requirements.

Notice:Ignoring these steps could result in costly
damage to the vehicle that would not be covered by
the warranty.
Trying to start the vehicle by pushing or pulling it
will not work, and it could damage the vehicle.
1. Check the other vehicle. It must have a 12-volt battery with a negative ground system.
Notice: Only use a vehicle that has a 12-volt system
with a negative ground for jump starting. If the other
vehicle does not have a 12-volt system with a
negative ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not
touching each other. If they are, it could cause a
ground connection you do not want. You would
not be able to start your vehicle, and the bad
grounding could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in P (Park) or a manual transmission
in Neutral before setting the parking brake. Notice:
If the radio or other accessories are left 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 outlet(s).
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 hood on the other vehicle and locate the positive (+) and negative (−) terminal locations on
that vehicle.
You will not see the battery of your vehicle under
the hood. It is located under the rear passenger's
seat. You will not need to access the battery for
jump starting. The remote positive (+) terminal is
for that purpose. See Engine Compartment
Overview
on page 6‑14for location.

To replace the wiper blade assembly:1. Turn the ignition to ACC/ACCESSORY with the engine off.
2. Pull the windshield wiper assembly away from the windshield.
3. Squeeze the tabs on each side of the wiper bladeassembly and slide the assembly off the end of the
wiper arm.
4. Replace the blade assembly with a new one.
Allowing the wiper blade arm to touch the
windshield when no wiper blade is installed could
damage the windshield. Any damage that occurs
would not be covered by your warranty. Do not
allow the wiper blade arm to touch the windshield.
5. Repeat the steps for the other wiper.

If the warning light comes on, stop as soon as possible
and inflate the tires to the recommended pressure
shown on the tire loading information label. See
Loading the Vehicle on page 5‑18.
A message to check the pressure in a specific tire
displays in the Driver Information Center (DIC). 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. 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
on page 4‑42andDIC Warnings and Messageson
page 4‑49.
The low tire pressure warning light may come on in
cool weather when the vehicle is first started, and then
turn off as the vehicle is driven. This could be an early
indicator that the air pressure is getting low and needs
to be inflated to the proper pressure. A Tire and Loading Information label shows the size
of the original equipment tires and the correct inflation
pressure for the tires when they are cold. See
Loading
the Vehicle
on page 5‑18, for an example of the Tire
and Loading Information label and its location on your
vehicle. Also see Inflation - 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. See Tire Inspection and Rotation
on
page 6‑70and Tires on page 6‑57.
Notice: Tire sealant materials are not all the same.
A non-approved tire sealant could damage the
TPMS sensors. TPMS sensor damage caused by
using an incorrect tire sealant is not covered by the
vehicle warranty. Always use only the GM-approved
tire sealant available through your dealer or
included in the vehicle.
Factory-installed Tire Inflator Kits use a GM approved
liquid tire sealant. Using non-approved tire sealants
could damage the TPMS sensors. See Tire Sealant and
Compressor Kit
on page 6‑80for information regarding
the inflator kit materials and instructions.

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 pressure
warning light flashes for about one minute and then
stays on for the remainder of the ignition cycle. A DIC
warning message also displays. The malfunction light
and DIC warning message come on at each ignition
cycle until the problem is corrected. Some of the
conditions that can cause these 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 malfunction light and the DIC message
should go off after the road tire is replaced and
the sensor matching process is performed
successfully. See "TPMS Sensor Matching
Process" later in this section.
.The TPMS sensor matching process was not done
or not completed successfully after rotating the
tires. The malfunction light and the DIC message
should go off after successfully completing the
sensor matching process. See "TPMS Sensor
Matching Process" later in this section.
.One or more TPMS sensors are missing or
damaged. The malfunction light and the DIC
message should go off when the TPMS sensors
are installed and the sensor matching process is
performed successfully. See your dealer for
service.
.Replacement tires or wheels do not match the
original equipment tires or wheels. Tires and
wheels other than those recommended could
prevent the TPMS from functioning properly. See
Buying New Tires on page 6‑72.
.Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning properly, it cannot detect
or signal a low tire condition. See your dealer for
service if the TPMS malfunction light and DIC message
comes on and stays on.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
The identification code needs to be matched to a new
tire/wheel position after rotating the vehicle’s tires or
replacing one or more of the TPMS sensors. Also, the
TPMS sensor matching process should be performed
after replacing a spare tire with a road tire containing
the TPMS sensor. The malfunction light and the DIC
message should go off at the next ignition cycle. The
sensors are matched to the tire/wheel positions, using a
TPMS relearn tool, in the following order: driver side
front tire, passenger side front tire, passenger side rear
tire, and driver side rear. See your dealer for service or
to purchase a relearn tool.
There are two minutes to match the first tire/wheel
position, and five minutes overall to match all four tire/
wheel positions. If it takes longer, the matching process
stops and must be restarted.
The TPMS sensor matching process is:1. Set the parking brake.
2. Turn the ignition to ON/RUN with the engine off.
3. Press the Remote Keyless Entry (RKE) transmitter's lock and unlock buttons at the same
time for approximately five seconds. The horn
sounds twice to signal the receiver is in relearn
mode and TIRE LEARNING ACTIVE message
displays on the DIC screen. 4. Start with the driver side front tire.
5. Place the relearn tool against the tire sidewall,
near the valve stem. Then press the button to
activate the TPMS sensor. A horn chirp confirms
that the sensor identification code has been
matched to this tire and wheel position.
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. The horn sounds two times to
indicate the sensor identification code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active. The
TIRE LEARNING ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading
Information label.
