98 Instruments and Controls
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 or Rainsense, the wipers continue
to run until they reach the base of the
windshield.
Rainsense
If equipped with Rainsense and the feature
is turned on, a sensor near the top center of
the windshield detects the amount of water
on the windshield and controls the
frequency of the windshield wiper based on
the current sensitivity setting.
Keep this area of the windshield clear of
debris to allow for best system performance.
AUTO :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 turn the Rainsense feature on or off, see
“Rain Sense Wipers” underVehicle
Personalization 0126.
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.
Windshield Washer
L m:Push the paddle marked with the
windshield washer symbol at the top of the
turn signal lever to spray washer fluid and
activate the wipers. The wipers will continue
until the paddle is released or the maximum
wash time is reached. When the paddle is
released, additional wipes may occur
depending on how long the windshield
washer had been activated. See Washer
Fluid 0324 for information on filling the
windshield washer fluid reservoir.
Rear Window Wiper/Washer
The rear window wiper/washer controls are
on the end of the windshield wiper lever.
Turn the controls to adjust the setting.

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.
See “Rear Camera Washer” later in this
section.
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 under the rear
spoiler.
The wiper operations return to normal when
the transmission is no longer in N (Neutral)
or the vehicle speed has increased. Auto Wipe in Reverse Gear
If the rear wiper control is off, the rear
wiper will automatically operate
continuously when the transmission is in
R (Reverse), and the front windshield wiper
is performing low or high speed wipes.
If the rear wiper control is off, the
transmission is in R (Reverse), and the front
windshield wiper is performing INT wipes,
then the rear wiper automatically performs
INT wipes.
This feature can be turned on or off. See
Vehicle Personalization
0126.
The windshield washer reservoir is used for
the windshield, rear window, and rear mirror
camera, if equipped. See Rear Camera Mirror
0 30. Check the fluid level in the reservoir if
either washer is not working. See Washer
Fluid 0324.
Rear Camera Washer

forward to spray washer fluid on the rear
camera lens. The lever returns to its starting
position when released. See Rear Camera

information from the Global Positioning
System (GPS) antenna, 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

Loading the Vehicle for Off-Road Driving
{Warning
.Unsecured cargo on the load floor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by flying objects. Secure
the cargo properly.
.Keep cargo in the cargo area as far
forward and as low as possible. The
heaviest things should be on the floor,
forward of the rear axle.
.Heavy loads on the roof raise the
vehicle's center of gravity, making it
more likely to roll over. You can be
seriously or fatally injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
For more information about loading the
vehicle, see Vehicle Load Limits 0222 and
Tires 0339.
Environmental Concerns
.Always use established trails, roads, and
areas that have been set aside for public
off-road recreational driving and obey all
posted regulations.
.Do not damage shrubs, flowers, trees,
or grasses or disturb wildlife.
.Do not park over things that burn. See
Parking over Things That Burn 0231.
Driving on Hills
Driving safely on hills requires good
judgment and an understanding of what the
vehicle can and cannot do.
{Warning
Many hills are simply too steep for any
vehicle. Driving up hills can cause the
vehicle to stall. Driving down hills can
cause loss of control. Driving across hills
can cause a rollover. You could be injured
or killed. Do not drive on steep hills.
Before driving on a hill, assess the
steepness, traction, and obstructions. If the
terrain ahead cannot be seen, get out of the
vehicle and walk the hill before driving
further.
When driving on hills:
.Use a low gear and keep a firm grip on
the steering wheel.
.Maintain a slow speed.
.When possible, drive straight up or down
the hill.
.Slow down when approaching the top of
the hill.
.Use headlamps even during the day to
make the vehicle more visible.
{Warning
Driving to the top of a hill at high speed
can cause a crash. There could be a
drop-off, embankment, cliff, or even
another vehicle. You could be seriously
injured or killed. As you near the top of a
hill, slow down and stay alert.
.Never go downhill forward or backward
with either the transmission or transfer
case in N (Neutral). The brakes could
overheat and you could lose control.
{Warning
If the vehicle has the two-speed
automatic or electronic transfer case,
shifting the transfer case to N (Neutral)
can cause your vehicle to roll even if the
transmission is in P (Park). This is because
the N (Neutral) position on the transfer (Continued)

Stop/Start System
If equipped and enabled, the Stop/Start
system will shut off the engine to help
conserve fuel. It has components designed
for the increased number of starts.
{Warning
The automatic engine Stop/Start feature
causes the engine to shut off while the
vehicle is still on. Do not exit the vehicle
before shifting to P (Park). The vehicle
may restart and move unexpectedly.
Always shift to P (Park), and then turn
the ignition off before exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied and the vehicle
is at a complete stop, the engine may turn
off. When stopped, the tachometer displays
AUTO STOP. See Tachometer0106. When
the brake pedal is released or the
accelerator pedal is pressed, the engine will
restart.
To maintain vehicle performance, other
conditions may cause the engine to
automatically restart before the brake pedal
is released. Auto Stops may not occur and/or Auto
Starts may occur because:
.The climate control settings require the
engine to be running to cool or heat the
vehicle interior.
.The vehicle battery charge is low.
.The vehicle battery has recently been
disconnected.
.Minimum vehicle speed has not been
reached since the last Auto Stop.
.The accelerator pedal is pressed.
.The engine or transmission is not at the
required operating temperature.
.The outside temperature is not in the
required operating range.
.The vehicle is shifted out of D (Drive) to
any gear other than P (Park).
.Tow/Haul Mode or other driver modes
have been selected.
.The vehicle is on a steep hill or grade.
.The driver door has been opened or the
driver seat belt has been unbuckled.
