306 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.
Never attach rental hitches or other
bumper-type hitches. Only use
frame-mounted hitches that do not
attach to the bumper.
Always seal any holes in your vehicle
if the trailer hitch removed. If not
sealed, dirt, water, and carbon
monoxide (CO) from the exhaust may
enter your vehicle. SeeEngine Exhaust
0 231.
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.
.Tires must be properly inflated to
support loads while towing a trailer.
See Tires 0342 for instructions on
proper tire inflation.
Safety Chains
Always attach chains between the
vehicle and the trailer, and attach the
chains to the holes on the trailer hitch
platform. Instructions about safety
chains may be provided by the hitch
manufacturer or by the trailer
manufacturer.
Cross the safety chains under the
tongue of the trailer to help prevent
the tongue from contacting the road if
it becomes separated from the hitch.
Always leave just enough slack so the
combination can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
Loaded trailers over 450 kg (1,000 lb)
must be equipped with brake systems
and with brakes for each axle. Trailer
braking equipment conforming to
Canadian Standards Association (CSA)
requirement CAN3-D313, or its
equivalent, is recommended. State or local regulations may require
trailers to have their own braking
system if the loaded weight of the
trailer exceeds certain minimums that
can vary from state to state. Read and
follow the instructions for the trailer
brakes so they are installed, adjusted,
and maintained properly. Never
attempt to tap into your vehicle's
hydraulic brake system. If you do,
both the vehicle anti-lock brakes and
the trailer brakes may not function,
which could result in a crash.
Turn Signals When Towing a
Trailer
When properly connected, the trailer
turn signals will illuminate to indicate
the vehicle is turning, changing lanes,
or stopping. When towing a trailer,
the arrows on the instrument cluster
will illuminate even if the trailer is not
properly connected or the bulbs are
burned out.

marks:
California Proposition
65 Warning
{Warning
Most motor vehicles, including this
one, as well as many of its service
parts and fluids, contain and/or
emit chemicals known to the State
of California to cause cancer and
birth defects or other reproductive
harm. Engine exhaust, many parts
and systems, many fluids, and
some component wear by-products
contain and/or emit these
chemicals. For more information go

correct order, making sure that the
cables do not touch each other or
other metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle and
removing the jumper cables, allow it
to idle for several minutes.
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty. Do not lash or
hook to suspension components.
Use the proper straps around the
tires to secure the vehicle. Do not
drag a locked wheel/tire. Use tire
skates or dollies under any locked
wheel/tire while loading the vehicle. (Continued)
Caution (Continued)
Do not use a sling type lift to tow
the vehicle. This could damage the
vehicle.
GM recommends a flatbed tow truck
to transport a disabled vehicle. Use
ramps to help reduce approach angles,
if necessary. A towed vehicle should
have its drive wheels off the ground.
Contact Roadside Service or a
professional towing service if the
disabled vehicle must be towed. See
Roadside Service 0405.
Tow Eye
Caution
Improper use of the tow eye can
damage the vehicle. If equipped, use
the tow eye to load a disabled
vehicle onto a flatbed tow truck
from a flat road surface, or to move
the vehicle a short distance. Use
caution and low speeds. The
transmission must be
in (N) Neutral when moving the
vehicle. If the vehicle is equipped with a tow
eye, only use the tow eye to pull the
vehicle onto a flatbed car carrier from
a flat road surface. Do not use the tow
eye to pull the vehicle from snow,
mud, or sand.
Front Tow Eye
Carefully open the cover in the fascia
by using the small notch that conceals
the tow eye socket.
Install the tow eye into the socket and
turn it until it is fully tightened. When
the tow eye is removed, reinstall the
cover with the notch in the original
position.

372 VEHICLE CARE
Rear Tow Eye
If equipped, carefully open the cover
by using the small notch that conceals
the rear tow eye socket.
Install the tow eye into the socket and
turn it until it is fully tightened. When
the tow eye is removed, reinstall the
cover with the notch in the original
position.
Recreational Vehicle
Towing
Caution
Dolly towing or dinghy towing the
vehicle may cause damage because
of reduced ground clearance.
Always put the vehicle on a flatbed
truck or trailer.
The vehicle was neither designed nor
intended to be towed with any of its
wheels on the ground. If the vehicle
must be towed, see Towing the Vehicle
0 371.
Appearance Care
Exterior Care
Locks
Locks are lubricated at the factory.
Use a de-icing agent only when
absolutely necessary, and have the
locks greased after using. See
Recommended Fluids and Lubricants
0392.
Washing the Vehicle
To preserve the vehicle's finish, wash
it often and out of direct sunlight.
Caution
Do not use petroleum-based, acidic,
or abrasive cleaning agents as they
can damage the vehicle's paint,
metal, or plastic parts. If damage
occurs, it would not be covered by
the vehicle warranty. Approved
cleaning products can be obtained
from your dealer. Follow all
manufacturer directions regarding
correct product usage, necessary
safety precautions, and appropriate
disposal of any vehicle care
product.
Caution
Avoid using high-pressure washes
closer than 30 cm (12 in) to the
surface of the vehicle. Use of power
washers exceeding 8 274 kPa
(1,200 psi) can result in damage or
removal of paint and decals.

CUSTOMER INFORMATION 409
limiting compensation for damage
repairs by using aftermarket collision
parts. Some insurance companies will
not specify aftermarket collision parts.
When purchasing insurance, we
recommend that you ensure that the
vehicle will be repaired with GM
original equipment collision parts.
If such insurance coverage is not
available from your current insurance
carrier, consider switching to another
insurance carrier.
If the vehicle is leased, the leasing
company may require you to have
insurance that ensures repairs with
Genuine GM Original Equipment
Manufacturer (OEM) parts or Genuine
Manufacturer replacement parts. Read
the lease carefully, as you may be
charged at the end of the lease for
poor quality repairs.
If a Crash Occurs
If there has been an injury, call
emergency services for help. Do not
leave the scene of a crash until all
matters have been taken care of. Move
the vehicle only if its position puts
you in danger, or you are instructed to
move it by a police officer.Give only the necessary information
to police and other parties involved in
the crash.
For emergency towing see
Roadside
Service 0405.
Gather the following information:
.Driver name, address, and telephone
number
.Driver license number
.Owner name, address, and
telephone number

.Vehicle make, model, and
model year

0 59.
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.
