Windshield Wiper/Washer
With the ignition in ACC/ACCESSORY
or ON/RUN, move the windshield
wiper lever up or down to select the
wiper speed.
HI : Use for fast wipes.
LO : Use for slow wipes.
AUTO : Use this setting for
intermittent wipes when Rainsense ™
is disabled, or for Rainsense wipes
when it is enabled. For intermittent
wipes, move the lever up to AUTO,
then turn the band on the wiper lever
up for more frequent wipes or down
for less frequent wipes. If Rainsense is
enabled, see “Rainsense™”later in this
section.
If the windshield wipers are in use
while driving, the exterior lamps come
on automatically if the exterior lamp
control is in AUTO. The transition
time for the lamps coming on varies
based on wiper speed. See “Lights On
with Wipers ”under Automatic
Headlamp System 0165.
OFF : Use to turn the wipers off. 1X :
For a single wipe, briefly move
the wiper lever down. For several
wipes, hold the wiper lever down.
f: Pull the windshield wiper lever
toward you to spray windshield
washer fluid and activate the wipers.
The wipers will continue until the
lever is released or the maximum
wash time is reached. When the
windshield wiper lever is released,
additional wipes may occur depending
on how long the windshield washer
had been activated. See Washer Fluid
0 260 for information on filling the
windshield washer fluid reservoir.
{Warning
In freezing weather, do not use the
washer until the windshield is
warmed. Otherwise the washer fluid
can form ice on the windshield,
blocking your vision.
Clear snow and ice from the wiper
blades and windshield before using
them. If frozen to the windshield,

110 INSTRUMENTS AND CONTROLS
carefully loosen or thaw them.
Damaged blades should be replaced.
SeeWiper Blade Replacement 0265.
Heavy snow or ice can overload the
wiper motor.
Wiper Parking
If the ignition is put in OFF while the
wipers are on LO, HI, or AUTO with
Rainsense disabled, they will
immediately stop.
If the windshield wiper lever is then
moved to OFF before the driver door is
opened or within 10 minutes after the
ignition is off, the wipers will restart
and move to the base of the
windshield.
If the ignition is put in OFF while the
wipers are performing wipes due to
windshield washing or Rainsense, the
wipers continue to run until they
reach the base of the windshield.
Rainsense™
With Rainsense, a sensor near the top
center of the windshield detects the
amount of water on the windshield
and controls the sensitivity of the
windshield wiper. Keep this area of the windshield clear
of debris to allow for best system
performance.
AUTO :
If Rainsense is enabled, move
the windshield wiper lever to AUTO.
Turn the band on the wiper lever to
adjust the sensitivity.
. Turn the band up for more
sensitivity to moisture.
. Turn the band down for less
sensitivity to moisture.
. Move the windshield wiper lever
out of the AUTO position to
deactivate Rainsense.
To enable or disable this feature, see
“Rainsense Wipers” underVehicle
Personalization 0152. Wiper Arm Assembly Protection
When using an automatic car wash,
move the windshield wiper lever to
OFF. This disables the automatic
Rainsense windshield wipers.
With Rainsense, if the transmission is
in N (Neutral) and the vehicle speed is
very slow, the wipers will
automatically stop at the base of the
windshield.
The wiper operations return to normal
when the transmission is no longer in
N (Neutral) or the vehicle speed has
increased.
Rear Camera Mirror Washer

wiper lever forward to spray washer
fluid on the rear camera mirror. The

188 DRIVING AND OPERATING
to a lower gear. Any sudden
changes could cause the tires to
slide.
Remember: Antilock brakes help avoid
only the braking skid.
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. (Continued)
Warning (Continued)
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 Tires0276.
. 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, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
