out. Do not carry more than 100 lbs. (45 kg) in your
rear area.

damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
If you put things inside your vehicle – like suitcases,
tools, packages or anything else – they will go as fast as
the vehicle goes. If you have to stop or turn quickly,
or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the rear area of your vehicle.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.

Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flames if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed
space. When you use anything from a container to clean
your vehicle, be sure to follow the manufacturer’s
warnings and instructions. And always open your doors
or windows when you are cleaning the inside.
Never use these to clean your vehicle:
•Gasoline
•Benzene
•Naphtha
•Carbon Tetrachloride
•Acetone
•Paint Thinner
•Turpentine
•Lacquer Thinner
•Nail Polish Remover
They can all be hazardous — some more than
others — and they can all damage your vehicle, too.

Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with a soft cloth. Then, let
the leather dry naturally. Do not use heat to dry.
•For stubborn stains, use a leather cleaner.
•Never use oils, varnishes, solvent-based or abrasive
cleaners, furniture polish or shoe polish on leather.
•Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the finish,
it can harm the leather.
Cleaning the Top of the
Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones
or waxes may cause annoying reflections in the
windshield and even make it difficult to see through the
windshield under certain conditions.
Cleaning Interior Plastic Components
Use only a mild soap and water solution on a soft cloth
or sponge. Commercial cleaners may affect the
surface finish.
Cleaning the Security Shade and
Convenience Net
Wash with warm water and mild detergent, rinse with
cold water and tumble dry on low. Do not use chlorine
bleach.
Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or a
liquid household glass cleaner will remove normal
tobacco smoke and dust films on interior glass. See
Vehicle Care/Appearance Materials on page 5-90.
Notice:If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch
the glass and/or cause damage to the rear window
defogger and the integrated radio antenna. When
cleaning the glass on your vehicle, use only a soft
cloth and glass cleaner.
