or other airborne
obstructions.
.The vehicle's windshield is
dirty, cracked, or obstructed
by something that blocks the
view of the light sensor.
.The vehicle is loaded such
that the front end points
upward, causing the light sensor to aim high and not
detect headlamps and
taillamps.

.Do not damage shrubs,
flowers, trees, or grasses or
disturb wildlife.
.Do not park over things that
burn. See Parking over
Things That Burn0255.
Driving on Hills
Driving safely on hills requires
good judgment and an
understanding of what the
vehicle can and cannot do.
{Warning
Many hills are simply too
steep for any vehicle. Driving
up hills can cause the vehicle
to stall. Driving down hills
can cause loss of control.
Driving across hills can
cause a rollover. You could
be injured or killed. Do not
drive on steep hills.
Before driving on a hill, assess
the steepness, traction, and
obstructions. If the terrain ahead cannot be seen, get out
of the vehicle and walk the hill
before driving further.
When driving on hills:
.Use a low gear and keep a
firm grip on the steering
wheel.
.Maintain a slow speed.
.When possible, drive straight
up or down the hill.
.Slow down when
approaching the top of
the hill.
{Warning
Driving to the top of a hill at
high speed can cause a
crash. There could be a
drop-off, embankment, cliff,
or even another vehicle. You
could be seriously injured or
killed. As you near the top of
a hill, slow down and stay
alert.
.Use headlamps even during
the day to make the vehicle
more visible.
.Never go downhill forward
or backward with the
transmission in N (Neutral).
The brakes could overheat
and you could lose control.
.When driving down a hill,
keep the vehicle headed
straight down. Use a low
gear because the engine will
work with the brakes to slow
the vehicle and help keep
the vehicle under control.
{Warning
Heavy braking when going
down a hill can cause your
brakes to overheat and fade.
This could cause loss of
control and you or others
could be injured or killed.
Apply the brakes lightly
when descending a hill and
use a low gear to keep
vehicle speed under control.
.Avoid turns that take the
vehicle across the incline of
the hill. Driving across an
incline puts more weight on

238 Driving and Operating
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.
More frequent maintenance
service is required. See
Maintenance Schedule0425.
Driving on Wet Roads
Rain and wet roads can
reduce vehicle traction and
affect your ability to stop and
accelerate. Always drive
slower in these types of
driving conditions and avoid
driving through large puddles
and deep-standing or flowing
water.
{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 0364.

Driving and Operating 241
Warning (Continued)
.Open a window about
5 cm (2 in) on the vehicle
side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the
highest setting. See
“Climate Control Systems.”
For more information about
CO, see Engine Exhaust
0 256.
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the
engine off and partially close
the window. Moving about to
keep warm also helps.
If it takes time for help to
arrive, when running the
engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
If stuck too severely for the
traction system to free the
vehicle, turn the traction
system off and use the rocking
method. See Traction Control/
Electronic Stability Control

267.
{Warning
If the vehicle's tires spin at
high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the
(Continued)
Warning (Continued)
wheels as little as possible
and avoid going above
56 km/h (35 mph).
For All-Wheel Drive (AWD),
select Off-Road or AWD mode.
See Driver Mode Control
0 269 and
All-Wheel Drive 0263.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until
the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when
the transmission is in gear.
Slowly spinning the wheels in
