CAUTION:
Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it's only shallow water, it can still wash away the ground from under your tires, and you could lose traction and roll the vehicle over. See "Driving Through Water" in the Index for more information on driving through water.
After Off-Road Driving
Remove any brush or debris that has collected on the underbody, chassis or under the hood. After operation in mud or sand, have the brake linings cleaned and checked. Check the body structure, steering, suspension, wheels, tires and exhaust system for damage. Also, check the fuel lines and cooling system for any leakage.

yellowblue Your vehicle will require more frequent service due to off-road use. 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.
Driving at Night
D Drive defensively. D Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
D Since you can't see as well, you may need to
slow down and keep more space between you and other vehicles. headlamps can light up only so much road ahead.
D Slow down, especially on higher speed roads. D If you're tired, pull off the road in a safe place
and rest.

Night Vision
No one can see as well at night as in the daytime. A 50-year-old driver may require at least twice as much light to see the same thing at night as a 20-year-old. For example, if you spend the day in bright sunshine you are wise to wear sunglasses. They may cut down on glare from headlamps, but they also make a lot of things invisible. It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (as from a driver who doesn't lower the high beams, or a vehicle with misaimed headlamps), slow down a little. Keep your windshield and all the glass on your vehicle clean -- inside and out. Dirty glass makes lights dazzle and flash more than clean glass would, making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a roadway when you are in a turn or curve. Keep your eyes moving; that way, it's easier to pick out dimly lighted objects. Just as your headlamps should be checked regularly for proper aim, so should your eyes be examined regularly. Some drivers suffer from night blindness -- the inability to see in dim light -- and aren't even aware of it.
