246 Driving and Operating
To lock the rear axle:1. Press the rear axle locking switch with the vehicle moving
less than 40 km/h (25 mph).
2. Wait for the light in the switch to stop flashing and remain
illuminated to show that the
rear axle is locked.
The locking rear axle will be
disengaged when the vehicle speed
exceeds 40 km/h (25 mph). The
Off-Road Mode allows the axle lock
to remain engaged at higher vehicle
speeds.
After pressing the switch to unlock
the axle, it may remain locked due
to torque in the driveline. The axle is
more easily unlocked by turning the
steering wheel to the right and to
the left while traveling at a low
speed.
Locking Front Axle
If equipped, the locking front axle
can give the vehicle additional
traction when traveling in off-road
situations such as mud, snow, steep
hills, and uneven terrain.
Caution
If you try to lock the axle while the
vehicle is stuck and the tires are
spinning, the vehicle’ s drivetrain
could be damaged. The repairs
would not be covered by the
vehicle warranty. Always lock the
axle before attempting situations
and/or navigating terrain that
could cause the vehicle to
become stuck.
Caution
If the vehicle’ s axle is locked
while driving on pavement, the
drivetrain could be damaged.
Repairs would not be covered by
the vehicle warranty. Do not use
the locking axle on pavement.
Before the front axle can be locked,
the rear axle must be locked and
the transfer case must be in 4
n.
To lock the front and rear axles:
1. Place the transfer case in 4
n.
This is the only mode that
allows the front axle to lock.
See Four-Wheel Drive 0231
for more information regarding
the transfer case and
four-wheel drive low operation.
2. Press the rear axle locking switch with the vehicle stopped
or moving less than 40 km/h
(25 mph).

262 Driving and Operating
Warning (Continued)
or the trailer brakes are
inadequate for the load, the
vehicle may not stop as expected.
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.
See Vehicle Load Limits 0210 for
more information about the vehicle's
maximum load capacity.
To identify the trailering capacity of
the vehicle, read the information in
“Weight of the Trailer” 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 your safety and that of
your passengers. Read this section
carefully before pulling a trailer.
Weight of the Trailer
Safe trailering requires monitoring
the weight, speed, altitude, road
grades, outside temperature, the
dimensions of the front of the trailer,
and how frequently the vehicle is
used to pull a trailer. Take into
consideration any special equipment
on the vehicle, and the amount of
tongue weight the vehicle can carry.
See
“Weight of the Trailer Tongue”
later in this section for more
information.
Trailer Weight Rating (TWR) is
calculated assuming the tow vehicle
has the driver, a front seat
passenger, and all required trailering
equipment. Weight of additional optional equipment, passengers,
and cargo in the tow vehicle must
be subtracted from the trailer weight
rating.
Use the following chart to determine
how much the vehicle can weigh,
based upon the vehicle model and
options.

and then try to turn the tire.
If the tire moves, use the wheel
wrench to tighten the cable.
8. Reinstall the spare tire lock, if the vehicle has one.
To store the jack and tools, reverse
the steps for removing them.
1. Wheel Wrench
2. Jack Handle
3. Jack Handle Extensions
4. Wing Nut
For extended cab models, be sure
to replace the wheel wrench (1),
jack handle (2), and two jack handle
extensions (3) in the bag, as shown,
so it can be properly stored in the
storage compartment. Be sure to fully tighten the wing
nut (4) so the tool bag cover can be
properly and securely closed.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check
that the spare tire is correctly
inflated after being installed on the
vehicle. The compact spare tire is
designed for temporary use only.
The vehicle will perform differently with the spare tire installed and it is
recommended that the vehicle
speed be limited to 80 km/h
(50 mph). To conserve the tread of
the spare tire, have the standard tire
repaired or replaced as soon as
convenient and return the spare tire
to the storage area.
When using a compact spare tire,
the AWD (if equipped), ABS, and
Traction Control systems may
engage until the spare tire is
recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible
wheel slip.
Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact
spare can get caught on the rails
which can damage the tire, wheel,
and other parts of the vehicle.
Do not use the compact spare on
other vehicles.

Managing the Vehicle Damage
Repair Process
In the event that the vehicle requires
damage repairs, GM recommends
that you take an active role in its
repair. If you have a pre-determined
repair facility of choice, take the
vehicle there, or have it towed there.
Specify to the facility that any
required replacement collision parts
be original equipment parts, either
new Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be covered by
the GM vehicle warranty.
Insurance pays the bill for the repair,
but you must live with the repair.
Depending on your policy limits,
your insurance company may
initially value the repair using
aftermarket parts. Discuss this with the repair professional, and insist on
Genuine GM parts. Remember,
if the vehicle is leased, you may be
obligated to have the vehicle
repaired with Genuine GM parts,
even if your insurance coverage
does not pay the full cost.
If another party's insurance
company is paying for the repairs,
you are not obligated to accept a
repair valuation based on that
insurance company's collision policy
repair limits, as you have no
contractual limits with that company.
In such cases, you can have control
of the repair and parts choices as
long as the cost stays within
reasonable limits.
