The vehicle can tow in
D (Drive). Shift the
transmission to a lower gear if
the transmission shifts too
often under heavy loads and/
or hilly conditions.
When towing at higher
altitudes, engine coolant will
boil at a lower temperature
than at lower altitudes. If the
engine is turned off
immediately after towing at
high altitude on steep uphill
grades, the vehicle could show
signs similar to engine
overheating. To avoid this, let
the engine run, preferably on
level ground, with the
transmission in P (Park) for a
few minutes before turning
the engine off. If the overheat
warning comes on, see Engine
Overheating0342.Parking on Hills
{Warning
To prevent serious injury or
death, always park your
vehicle and trailer on a level
surface when possible.
When parking your vehicle and
your trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into
the curb if facing downhill
or into traffic if facing
uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, gradually
release the brake pedal to
allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking
brake and shift into
P (Park). 5. Release the brake pedal.
Leaving After Parking on
a Hill
1. Apply and hold the brake
pedal.
.Start the engine.
.Shift into the
desired gear.
.Release the parking
brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer
Towing
The vehicle needs service
more often when used to tow
trailers. See Maintenance
Schedule 0425. It is especially
important to check the
automatic transmission fluid,
engine oil, axle lubricant, belts,

322 Driving and Operating
Towing Equipment
Hitches
Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going
by, and rough roads can affect
the trailer and the hitch.
Proper hitch equipment for
your vehicle helps maintain
control of the vehicle-trailer
combination. Many trailers can
be towed using a
weight-carrying hitch which
has a coupler latched to the
hitch ball, or a tow eye latched
to a pintle hook. Other trailers
may require a
weight-distributing hitch that
uses spring bars to distribute
the trailer tongue weight
between your vehicle and
trailer axles. See“Maximum
Trailer Tongue Weight” under
Trailer Towing 0318 for
weight limits with various hitch
types. Never attach rental hitches or
other bumper-type hitches.
Only use frame-mounted
hitches that do not attach to
the bumper.
Hitch Cover
To remove hitch cover,
if equipped:
1. Remove the two fasteners on the lower tabs.
2. Pull the lower edge of the cover to about a 45 degree
angle.
3. Pull the cover downward to disengage the upper
attachments. To reinstall the hitch cover:
1. Hold cover at a 45 degree angle to the vehicle and
push the upper tabs into
the slots in the bumper.
2. Push the bottom of the cover forward until the
lower tabs line up with the
lower slots.
3. Snap the hitch cover into place by pushing the upper
corners forward.
4. Reinstall the two fasteners on the lower tabs.
Consider using mechanical
sway controls with any trailer.
Ask a trailering professional
about sway controls or refer
to the trailer manufacturer's
recommendations and
instructions.
Tires
.Do not tow a trailer while
using a compact spare tire
on the vehicle.

Brake Fluid
The brake master cylinder
reservoir is filled with GM
approved DOT 4 brake fluid as
indicated on the reservoir cap.
See Engine Compartment
Overview0331 for the
location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on
a level surface, the brake fluid
level should be between the
minimum and maximum marks
on the brake fluid reservoir.
There are only two reasons
why the brake fluid level in the
reservoir may go down:
.Normal brake lining wear.
When new linings are
installed, the fluid level goes
back up.
.A fluid leak in the brake
hydraulic system. Have the
brake hydraulic system fixed.
With a leak, the brakes will
not work well.
Always clean the brake fluid
reservoir cap and the area
around the cap before
removing it.
Do not top off the brake fluid.
Adding fluid does not correct a
leak. If fluid is added when the
linings are worn, there will be
too much fluid when new
brake linings are installed. Add
or remove fluid, as necessary,
only when work is done on the
brake hydraulic system.
{Warning
If too much brake fluid is
added, it can spill on the
engine and burn, if the
engine is hot enough. You or
others could be burned, and
the vehicle could be (Continued)
Warning (Continued)
damaged. Add brake fluid
only when work is done on
the brake hydraulic system.
When the brake fluid falls to a
low level, the brake warning
light comes on. See Brake
System Warning Light 0128.
Brake fluid absorbs water over
time which degrades the
effectiveness of the brake
fluid. Replace brake fluid at the
specified intervals to prevent
increased stopping distance.
See Maintenance Schedule
0 425.
What to Add
Use only GM approved DOT 4
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0429.

346 Vehicle Care
{Warning
The wrong or contaminated
brake fluid could result in
damage to the brake
system. This could result in
the loss of braking leading to
a possible injury. Always use
the proper GM approved
brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Immediately wash
off any painted surface.
Battery - North
America
The original equipment battery
is maintenance free. Do not
remove the cap and do not
add fluid.Refer to the replacement
number on the original battery
label when a new battery is
needed. For replacement of
the battery, see your dealer.

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. Do not mix the compact spare
tire or wheel with other
wheels or tires. They will not
fit. Keep the spare tire and its
wheel together.
Caution
Tire chains will not fit the
compact spare. Using them
can damage the vehicle and
the chains. Do not use tire
chains on the compact
spare.
