If the windshield wiper lever is then moved
to OFF before the driver door is opened or
within 10 minutes, the wipers will restart
and move to the base of the windshield.
If the ignition is turned off while the wipers
are performing wipes due to windshield
washing, the wipers continue to run until
they reach the base of the windshield.
Rear Window Wiper/Washer
The rear window wiper/washer controls are
on the end of the windshield wiper lever.
Turn the controls to adjust the setting.
OFF :Turns the wiper off.
INT : Turns on the rear wiper with a delay
between wipes.
ON : Turns on the rear wiper.
1:Push the windshield wiper lever
forward to spray washer fluid on the rear
window. The wipers will clear the rear
window and either stop or return to your
preset speed. For more washer cycles, press
and hold the lever.
The rear window wiper/washer will not
operate if the liftgate is open or ajar. If the
liftgate is opened while the rear wiper is on,
the wiper returns to the parked position and
stops.
Rear Wiper Arm Assembly Protection
When using an automatic car wash, move
the rear wiper control to OFF to disable the
rear wiper. In some vehicles, if the
transmission is in N (Neutral) and the
vehicle speed is very slow, the rear wiper
will automatically park.
The wiper operations return to normal when
the transmission is no longer in N (Neutral)
or the vehicle speed has increased.
Reverse Gear Wipes
If the rear wiper control is off, the rear
wiper will automatically operate
continuously when the vehicle is in
R (Reverse) and the front windshield wiper is
performing low or high speed wipes. If the
rear wiper control is off, the vehicle is in R (Reverse), and the front windshield wiper
is performing interval wipes, then the rear
wiper automatically performs interval wipes.
This feature can be turned on or off. See
Vehicle Personalization
0123.

Driving and Operating 207
More frequent maintenance service is
required. SeeMaintenance Schedule 0346.
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
(Continued)
Warning (Continued)
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.
SeeTires 0300.
.Turn off cruise control.
.Activate All-Wheel Drive (AWD) mode. See
Driver Mode Control 0228.
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, brakes, tires, cooling
system, and transmission.
.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.
