air suspension GMC SIERRA 1995 Owners Manual

After Off-Road Driving
Remove any brush or debris that has collected on the underbody, chassis or
under the hood. These accumulations can be
a fire hazard.
After operation
in mud or sand, have the brake linings cleaned and checked.
These substances can cause glazing and uneven braking. Check the body
structure, steering, suspension. wheels, tires, and exhaust system for
damage.
Also, check the fuel lines and cooling system for any leakage.
Your vehicle
will require more frequent service due to off-road use. Refer
to the Maintenance Schedule for additional information.
Driving at Night
Night driving is more dangerous than day driving. One reason is that some
drivers are likely
to be impaired - by alcohol or drugs, with night vision
problems,
or by fatigue.
Here are some tips on night driving.
0 Drive defensively.
