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
Lubricants0429.
Washing the Vehicle
To preserve the vehicle's
finish, wash it often and out of
direct sunlight.
Caution

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
(Continued)
Caution (Continued)
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.
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.
Cleaning Underhood
Components
Caution
Do not power wash any
component under the hood
that has this
esymbol.
This could cause damage
that would not be covered
by the vehicle warranty.
Solvents or aggressive
cleaners may harm underhood
components. The usages of
these chemicals should be
avoided.

416 Vehicle Care
Caution
To avoid surface damage on
wheels and wheel trim, do
not use strong soaps,
chemicals, abrasive polishes,
cleaners, or brushes. Use
only GM approved cleaners.
Do not drive the vehicle
through an automatic car
wash that uses silicon
carbide tire/wheel cleaning
brushes. Damage could
occur and the repairs would
not be covered by the
vehicle warranty.
Brake System
Visually inspect brake lines
and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Inspect disc brake pads
for wear and rotors for
surface condition. Inspect
drum brake linings/shoes for
wear or cracks. Inspect all
other brake parts.
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 hinges,
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.
