120 INSTRUMENTS AND CONTROLS
Automatic Heated Steering Wheel
If equipped with remote start, the
heated steering wheel will turn on
automatically during a remote start
along with the heated seats when it is
cold outside. The heated steering
wheel indicator light may not
come on.
If equipped with auto heated seats,
the heated steering wheel will turn on
when the auto heated seat is
activated. The heated steering wheel
indicator will follow the state of the
steering wheel heat.
SeeHeated and Ventilated Front Seats
0 72 and Vehicle Personalization 0170.
Horn
Pressaon the steering wheel pad to
sound the horn.
Windshield Wiper/Washer
With the ignition on or in ACC/
ACCESSORY, move the 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 0185.
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,

INSTRUMENTS AND CONTROLS 121
additional wipes may occur depending
on how long the windshield washer
had been activated. SeeWasher Fluid
0 322 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,
carefully loosen or thaw them.
Damaged blades should be replaced.
See Wiper Blade Replacement 0327.
Heavy snow or ice can overload the
wiper motor.
Wiper Parking
If the ignition is turned 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 turned 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 0170.
Wiper Arm Assembly Protection
When using an automatic car wash,
move the windshield wiper lever to
OFF. This disables the automatic
Rainsense windshield wipers.

122 INSTRUMENTS AND CONTROLS
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 Washer
If equipped, push the windshield
wiper lever forward to spray washer
fluid on the rear camera lens. The
lever returns to its starting position
when released. SeeRear Camera Mirror
0 56.
Compass
The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass receives its
heading and other information from
the Global Positioning System (GPS)
antenna, StabiliTrak
®, and vehicle
speed information.
The compass system is designed to
operate for a certain number of miles
or degrees of turn before needing a
signal from the GPS satellites. When
the compass display shows CAL, drive
the vehicle for a short distance in an
open area where it can receive a GPS
signal. The compass system will
automatically determine when a GPS
signal is restored and provide a
heading again.

used to access the time and date
settings through the menu system.

some action that may be needed to
correct a condition. Multiple messages
may appear one after another.
The messages that do not require
immediate action can be
acknowledged and cleared by pressing
V. The messages that require
immediate action cannot be cleared
until that action is performed.
All messages should be taken
seriously; clearing the message does
not correct the problem.
If a SERVICE message appears, see
your dealer.
Follow the instructions given in the
messages. The system displays
messages regarding the following
topics:
. Service Messages

Engine Power Messages
ENGINE/PROPULSION POWER IS
REDUCED
This message displays when the
vehicle's propulsion power is reduced.
Reduced propulsion power can affect
the vehicle's ability to accelerate.
If this message is on, but there is no
observed reduction in performance,
proceed to your destination. The
performance may be reduced the next
time the vehicle is driven. The vehicle
may be driven at a reduced speed
while this message is on, but maximum acceleration and speed may
be reduced. Anytime this message
stays on, or displays repeatedly, the
vehicle should be taken to your dealer
for service as soon as possible.
Vehicle Speed Messages
SPEED LIMITED TO
XXX KM/H (MPH)
This message shows that the vehicle
speed has been limited to the speed
displayed. The limited speed is a
protection for various propulsion and
vehicle systems, such as lubrication,
thermal, suspension, Teen Driver if
equipped, or tires.

210 DRIVING AND OPERATING
If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the accelerator
pedal and steer the way you want
the vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs.
. Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer
and vehicle control can be affected
when traction is reduced by water,
snow, ice, gravel, or other material
on the road. Learn to recognize
warning clues —such as enough
water, ice, or packed snow on the
road to make a mirrored surface
— and slow down when you have
any doubt.
. Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting
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.
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.
