behind the seat. Secure the items
and replace the jack cover.
NOTICE:

bed.
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. The method
known as “rocking” can help you get out when you’re
stuck, but
you must use caution.

Spinning your wheels can destroy parts of your vehicle as well as
the tires.
If you spin the wheels too fast while shifting your
transmission back and forth, you can destroy your transmission.

Don’t add anything to your oil. Your GM dealer is ready to advise if you
think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
0 It’s below freezing outside and most trips are less than 10 miles (16
km).
The engine is at low speed most of the time (as in door-to-door
delivery, or in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
0 The vehicle is frequently operated off-road.
If any one of these is true for your vehicle, then you need to change your oil
andfilter every 3,000 miles (5 000 km) or 3 months - whichever comes
first.
If none of them is true, change the oil every
7,500 miles (12 500 km) or 12
months - whichever comes first. Change the filter at the first oil change
and at every other oil change after that.
Four-wheel Drive Remote Oil Filter
If your vehicle has four-wheel drive, you will have a remote oil filter
located under the radiator support. There is a special access \
door in the
vehicle body skirt shield.
Engine Coolant Heater (Engine Block Heater)
An engine coolant heater can be a big help if you have to park outside in
very cold weather,
0 “F (-1 8 O C) or colder. If your vehicle has this option,
see “Engine Coolant Heater
” in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or properly throw away clothing or rags
containing wed engine oil. (See the manufacturer’s warnings about the use
and disposal of oil products.)
