Rear Compartment
Fuse Block
The rear compartment fuse
block is in the cargo area, on
the driver side of the vehicle
behind the lower trim panel. To access the fuses in the
Rear Electrical Center, remove
the center cargo bin, then
small side bin. See Rear
Storage
0109. See your dealer
if additional assistance is
needed.
The label for this fuse block is
in the spare tire area, on the
foam under the cargo floor.
The vehicle may not be
equipped with all of the fuses,
relays, and features shown.

Vehicle Care 445
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 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 electrical connections,
binding, cracks, chafing, etc.
Visually check constant
velocity joint boots and axle
seals for leaks.
Body Component
Lubrication
Lubricate all key lock cylinders,
door hinges, 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.
