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 washer fluid and
activate the wipers. The wipers will continue
until the lever is released or the maximum
wash time is reached. When the lever is
released, additional wipes may occur
depending on how long the windshield
washer had been activated. See Washer
Fluid 0256 for information on filling the
windshield washer fluid reservoir.
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 0262.
Heavy snow or ice can overload the wiper
motor.
{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.
{Warning
Before driving the vehicle, always clear
snow and ice from the hood, windshield,
washer nozzles, roof, and rear of the
vehicle, including all lamps and windows.
Reduced visibility from snow and ice
buildup could lead to a crash.
Wiper Parking
If the ignition is turned off while the wipers
are on LO, HI, or INT, they will
immediately stop.
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.
Compass
The vehicle may have a compass display on
the center stack. The compass receives its
heading and other information from the
Global Positioning System (GPS) antenna,
Electronic Stability Control, 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
Set the time and date using the
infotainment system. See "Time/Date" under
Settings 0150.

184 Driving and Operating
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 0271.
.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:
.When driving downhill in D (Drive), the
vehicle may automatically downshift to
assist with speed control.
.A lower gear may also be selected to
provide further speed control.
{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.
.Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
.Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
.Pay attention to special road signs
(e.g., falling rocks area, winding roads,
long grades, passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Caution
To avoid damage to the wheels and
brake components, always clear snow and
ice from inside the wheels and
underneath the vehicle before driving.
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. See Traction
Control/Electronic Stability Control 0206.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0204.

Then check to see if the engine cooling fans
are running. There are two cooling fans
located in the front (one at each corner) and
two cooling fans in the rear (one on each
side of the engine). If the engine is
overheating, the fans should be running.
If they are not, do not continue to run the
engine, and have the vehicle serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If Steam Is Coming from the Engine
Compartment with no Overheat Warning
Water from rain and car washes could enter
the engine compartment and contact hot
surfaces. If steam is coming from the engine
compartment with no accompanying
overheat warning, no service is needed.
If No Steam Is Coming from the Engine
If an engine overheat warning is displayed
but no steam can be seen or heard, the
problem may not be too serious. Sometimes
the engine can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayed with no
sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral), and
let the engine idle. If the engine coolant temperature gauge is
no longer in the shaded area or an overheat
warning no longer displays, the vehicle can
be driven. Continue to drive the vehicle
slowly for about 10 minutes. Keep a safe
vehicle distance from the vehicle in front.
If the warning does not come back on,
continue to drive normally and have the
cooling system checked for proper fill and
function.
If the warning continues, pull over safely,
and park the vehicle right away.
If there is no sign of steam, idle the engine
for three minutes while parked. If the
warning is still displayed, turn off the
engine until it cools down.Washer Fluid
What to Use
When the vehicle needs windshield washer
fluid, be sure to read the manufacturer
instructions before use. If the vehicle will be
operating in an area where the temperature
may fall below freezing, use a fluid that has
sufficient protection against freezing.

Vehicle Care 257
Adding Washer Fluid
1. Open the hood. SeeHood017.
2. Open the cap with the washer symbol
on it. Add washer fluid until the tank
is full.
Caution
.Do not use washer fluid that contains
any type of water repellent coating.
This can cause the wiper blades to
chatter or skip.
.Do not use engine coolant (antifreeze)
in the windshield washer. It can
damage the windshield washer system
and paint.
.Do not mix water with ready-to-use
washer fluid. Water can cause the
solution to freeze and damage the
washer fluid tank and other parts of
the washer system.
(Continued)
Caution (Continued)
.When using concentrated washer fluid,
follow the manufacturer instructions
for adding water.
.Fill the washer fluid tank only
three-quarters full when it is very cold.
This allows for fluid expansion if
freezing occurs, which could damage
the tank if it is completely full.
Brakes
Disc brake linings have built-in wear
indicators that make a high-pitched warning
sound when the brake linings are worn and
new linings are needed. The sound can come
and go or can be heard all the time when
the vehicle is moving, except when applying
the brake pedal firmly.
{Warning
The brake wear warning sound means
that soon the brakes will not work well.
That could lead to a crash. When the
brake wear warning sound is heard, have
the vehicle serviced.
Caution
Continuing to drive with worn-out brake
linings could result in costly brake
repairs.
Properly torqued wheel nuts are necessary
to help prevent brake pulsation. When tires
are rotated, inspect brake linings for wear
and evenly tighten wheel nuts in the proper
sequence to torque specifications. See
Capacities and Specifications 0315.
Brake linings should be replaced as complete
axle sets.
Brake Squeal and Brake Dust
Some driving conditions or climates can
cause a brake squeal when the brakes are
first applied, clearing up following several
applies. This does not mean something is
wrong with the brakes.
Vehicles equipped with high performance
brake systems provide superior fade
resistance but will produce increased brake
squeal and brake dust on the wheels and
calipers as compared to standard brake
linings. This is normal.
