INSTRUMENTS AND CONTROLS 113
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.
nL: 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
0 251 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.
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.
Clock
The time and date for the clock can be
set using the infotainment system. See
“Time/Date ”in “System“under
“Settings ”in the infotainment manual.
Power Outlets
Power Outlets 12-Volt Direct
Current
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
The vehicle has two accessory power
outlets:
.
Inside the front storage area below
the climate control system.
. Inside the center console.
Lift the cover to access the accessory
power outlet.
The vehicle has two charging only
USB ports on the rear of the center
storage console.

174 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 enoughand 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 Tires0267.
. 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.
{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.

VEHICLE CARE 251
The power steering fluid reservoir is
under the engine cover on the
passenger side toward the rear of the
engine compartment. SeeEngine
Compartment Overview 0236.
When to Check Power Steering
Fluid
It is not necessary to regularly check
power steering fluid unless you
suspect there is a leak in the system
or an unusual noise is heard. A fluid
loss in this system could indicate a
problem. Have the system inspected
and repaired.
How to Check Power Steering
Fluid
Check the level when the engine
is cool.
To check the power steering fluid:
1. Remove the engine cover. Refer toEngine Cover 0239.
2. Wipe the cap and the top of the reservoir clean.
3. Turn the cap counterclockwise and pull it straight up. 4. Wipe the dipstick with a
clean rag.
5. Replace the cap and completely tighten it.
6. Remove the cap again and look at the fluid level on the dipstick.
The fluid level should be
between MIN and MAX on the
dipstick.
What to Use
To determine what kind of fluid to
use, see Recommended Fluids and
Lubricants 0326. Always use the
proper fluid.
Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before use. If operating the vehicle in an area
where the temperature may fall below
freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
The appropriate message will appear
in the Driver Information Center (DIC)
when the fluid level is low.
Open the cap with the washer symbol
on it. Add washer fluid until the tank
is full. See
Engine Compartment
Overview 0236 for reservoir location.
Caution
.
Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
