152 Driving and Operating
Warning
Wet brakes can cause crashes. They
might not work as well in a quick stop
and could cause pulling to one side. You
could lose control of the vehicle.
After driving through a large puddle of
water or a car/vehicle wash, lightly apply
the brake pedal until the brakes work
normally.
Flowing or rushing water creates strong
forces. Driving through flowing water
could cause the vehicle to be carried
away. If this happens, you and other
vehicle occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive through
flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build
up under the vehicle's tires so they actually
ride on the water. This can happen if the
road is wet enough and you are going fast
enough. When the vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to slow
down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather
driving tips include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping equipment in
good shape.
Keep the windshield washer fluid reservoir
filled.
Have good tires with proper tread depth.
See Tires 0 263.
Turn off cruise control.

Hill and Mountain Roads

Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain. Tips include:
Keep the vehicle serviced and in good
shape.
Check all fluid levels and brakes, tires, and
cooling system.
Shift to a lower gear when going down
steep or long hills.
Warning
Using the brakes to slow the vehicle on a
long downhill slope can cause brake
overheating, can reduce brake
performance, and could result in a loss of
braking. Shift the transmission to a lower
gear to let the engine assist the brakes
on a steep downhill slope.
Warning
Coasting downhill in N (Neutral) or with
the ignition off is dangerous. This can
cause overheating of the brakes and loss
of steering assist. Always have the engine
running and the vehicle in gear.
Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
Pay attention to special road signs (e.g.,
falling rocks area, winding roads, long
grades, passing or no-passing zones) and
take appropriate action.
