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
0313.
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

manufacturer directions regarding
(Continued)
Caution (Continued)
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.
Caution
Do not power wash any component
under the hood that has this
e
symbol.
This could cause damage that
would not be covered by the vehicle
warranty.
Caution
Some automatic car washes can
cause damage to the vehicle, wheels
and ground effects. Automatic car
washes are not recommended, due
to lack of clearance for the
undercarriage and/or wide rear tires
and wheels.
If using an automatic car wash, follow
the car wash instructions. The
windshield wiper and rear window
wiper, if equipped, must be off.
Remove any accessories that may be
damaged or interfere with the car
wash equipment.
Rinse the vehicle well, before washing
and after, to remove all cleaning
agents completely. If they are allowed
to dry on the surface, they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.

VEHICLE CARE 297
Steering, Suspension, and
Chassis Components
Visually inspect steering, suspension,
and chassis components for damaged,
loose, or missing parts or signs of
wear at least once a year.
Inspect power steering for proper
attachment, connections, binding,
leaks, cracks, chafing, etc.
Visually check constant velocity joint
boots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood
hinges, liftgate hinges, and the steel
fuel door hinge, unless the
components are plastic. Applying
silicone grease on weatherstrips with a
clean cloth will make them last
longer, seal better, and not stick or
squeak.
Underbody Maintenance
At least twice a year, spring and fall,
use plain water to flush any corrosive
materials from the underbody. Take
care to thoroughly clean any areas
where mud and other debris can
collect.Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate
the fluid. Contaminated fluid will
decrease the life of the transfer case
and/or axles and should be replaced
Sheet Metal Damage
If the vehicle is damaged and requires
sheet metal repair or replacement,
make sure the body repair shop
applies anti-corrosion material to
parts repaired or replaced to restore
corrosion protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoid
corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon and
attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface. See
“Finish Care”previously in
this section.
Interior Care
To prevent dirt particle abrasions,
regularly clean the vehicle's interior.
Immediately remove any soils.
Newspapers or dark garments can
transfer color to the vehicle’s interior.
Use a soft bristle brush to remove
dust from knobs and crevices on the
instrument cluster. Using a mild soap
solution, immediately remove hand
lotions, sunscreen, and insect
repellent from all interior surfaces or
permanent damage may result.
Use cleaners specifically designed for
the surfaces being cleaned to prevent
permanent damage. Apply all cleaners
directly to the cleaning cloth. Do not
spray cleaners on any switches or
controls. Remove cleaners quickly.

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.Publication Ordering
