Driving At Night - GMC Sierra Denali 2009 Owner's 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 and check the fuel lines and cooling
system for any leakage.
The vehicle requires 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 because
some drivers are likely to be impaired — by alcohol or
drugs, with night vision problems, or by fatigue.
Night driving tips include:
•
Drive defensively.
•
Do not drink and drive.
•
Reduce headlamp glare by adjusting the inside
rearview mirror.
•
Slow down and keep more space between you and
other vehicles because headlamps can only light up
so much road ahead.
•
Watch for animals.
•
When tired, pull off the road.
•
Do not wear sunglasses.
•
Avoid staring directly into approaching headlamps.
•
Keep the windshield and all glass on your vehicle
clean — inside and out.
•
Keep your eyes moving, especially during turns or
curves.
No one can see as well at night as in the daytime. But, as
we get older, these differences increase. A 50-year-old
driver might need at least twice as much light to see the
same thing at night as a 20-year-old.
