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 frontwindshield 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 0135.
The windshield washer reservoir is
used for the windshield and the rear
window. Check the fluid level in the
reservoir if either washer is not
working. See Washer Fluid 0322.
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. See
Rear Camera
Mirror 032.
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/
Electronic Stability Control (ESC),
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.

230 Driving and Operating
.Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0344.
. Turn off cruise control.
. Activate All-Wheel Drive (AWD)
mode. See All-Wheel Drive
0 250.
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.
. 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.
. Select All-Wheel Drive (AWD)
Mode. See All-Wheel Drive
0 250.
Winter Driving
Driving on Snow or Ice
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.

14018934) - 2020 - CRC - 2/27/20
296 Driving and Operating
If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle could show signs similar to
engine overheating. To avoid this,
let the engine run, preferably on
level ground, with the transmission
in P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating0321.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and
trailer on a level surface when
possible.
When parking your vehicle and your
trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill. 2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in place, gradually release the
brake pedal to allow the chocks
to absorb the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the engine.
. Shift into a gear.
. Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when used to tow trailers. See
Maintenance Schedule 0390. It is
especially important to check the
automatic transmission fluid, engine
oil, axle lubricant, belts, cooling
system, and brake system before
and during each trip.
Check periodically that all nuts and
bolts on the trailer hitch are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
0 321.
Trailer Towing
Caution
Towing a trailer improperly can
damage the vehicle and result in
costly repairs not covered by the

system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:1. Display the REMAINING OIL
LIFE on the DIC. See Driver
Information Center (DIC) (Base
Level) 0123 or
Driver Information Center (DIC)
(Uplevel) 0127. This display
shows an estimate of the oil’ s
remaining useful life. If 99% is
displayed, that means that 99%
of the current oil life remains.
2. Press and hold
lor the
thumbwheel while the Oil Life
display is active. The oil life will
change to 100%.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.
Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, you should
have this done at your dealer.
Change the fluid at the intervals
listed in
Maintenance Schedule
0 390, and be sure to use the fluid
listed in Recommended Fluids and
Lubricants 0399.
Engine Air Filter Life
System
When to Change Engine Air
Filter
If equipped, this feature provides an
indication of when to change the
engine air filter. It is based on
driving conditions, which can cause
when to change to vary greatly. It is
possible an air filter change may not
be indicated for up to four years.

has a 12-volt system with a
negative ground for jump starting.
2. Position the two vehicles so that they are not touching.
3. Set the parking brake firmly and put the shift lever in
P (Park) with an automatic
transmission, or Neutral with a
manual transmission.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting. 4. Turn the ignition off. Turn off all
lights and accessories in both
vehicles, except the hazard
warning flashers if needed.
{Warning
