1997 CHEVROLET EXPRESS ECU

Downloaded from www.Manualslib.com manuals search engine 5. Put the flat end of the extension on an angle through
the hole in the rear door frame, above the bumper.
Turn the ratchet clockwise until the tire is against the
underside
of the vehicle.
You will hear two “clicks” when the tire is up all the
way. Try to move the tire with your hands to make
sure
it is securely in place.
Return the jacking equipment to the proper location.
Secure the items and replace the jack cover.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you
must use caution.
I
A CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transmission
or other parts of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels
as little as possible. Don’t
spin the wheels above
35 mph (55 kmk) as shown
on the speedometer.

Downloaded from www.Manualslib.com manuals search engine Tire Chains
NOTICE:
Use tire chains only where legal and only when
you must. Use chains that are the proper size
for your tires. Install them on the tires of the
rear axle.
Tighten them as tightly
as possible with the ends
securely fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and retighten
them.
If the contact continues, slow down until it
stops. Driving too fast
or spinning the wheels with
chains on will damage your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst
into flame 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’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline
0 Benzene
0 Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
0 Lacquer Thinner
Nail Polish Remover
They can all be hazardous
-- some more than
others
-- and they can all damage your vehicle, too.
