In this mode, ESP and TCS, except for the ªlimited slipº
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 40 mph (64 km/h). At 40
mph (64 km/h) the system returns to ªPartial Offº mode,
described above. When the vehicle speed drops below 35
mph (56 km/h) the ESP system shuts off. ESP is deacti-
vated at low vehicle speeds so that it will not interfere
with off-road driving but ESP function returns to provide
the stability feature at speeds above 40 mph (64 km/h).
The ªESP/TCS Indicator Lightº will always be illumi-
nated when ESP is off. To turn ESP on again, momen-
tarily depress the ªESP OFFº switch. This will restore the
normal ªESP Onº mode of operation.
NOTE:The ªESP OFFº message will display and the
audible chime will sound when the gear selector is
placed into the ªPº (Park) position from any other
position, and then moved out of the ªPº (Park) position.
This will occur even if the message was previously
cleared.WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The ªFull Offº ESP mode is intended for
off-road use only.
4WD Low Range
Full Off
This is the normal operating mode for ESP in 4WD low
range. Whenever the vehicle is started in 4WD low range,
or the transfer case (if equipped) is shifted from 4WD
high range or neutral to 4WD low range, the ESP system
will be in this ªFull Offº mode. In 4WD low range, ESP
and TCS, except for the ªlimited slipº feature described
in the TCS section, are turned off until the vehicle reaches

a speed of 40 mph (64 km/h). At 40 mph (64 km/h), the
normal ESP stability function returns but TCS remains
off. When the vehicle speed drops below 35 mph (56
km/h), the ESP system shuts off. ESP is deactivated at
low vehicle speeds in 4WD low range so that it will not
interfere with off-road driving but ESP function returns
to provide the stability feature at speeds above 40 mph
(64 km/h). The9ESP/TCS Indicator Light9will always be
illuminated in 4WD low range when ESP is off.
NOTE:The ªESP OFFº message will display and the
audible chime will sound when the gear selector is
placed into the ªPº (Park) position from any other
position, and then moved out of the ªPº (Park) position.

road use only.
TSC (Trailer Sway Control)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from

HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
²Vehicle must be stopped.
²Vehicle must be on a 8% grade or greater hill.
²Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in R (Reverse) gear).
HSA will work in R (Reverse) and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in N (Neutral) or P (Park).
WARNING!
There may be situations on minor hills (i.e., less than
8%), with a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight rolling
may occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Towing with HSA
HSA will provide assistance when starting on a grade
when pulling a trailer.

If the ªESP/BAS Warning Lampº comes on
continuously with the engine running, a mal-
function has been detected in either the ESP or
the BAS system, or both. If this light remains on
after several ignition cycles, and the vehicle has been
driven several miles at speeds greater than 30 mph (48
km/h), see your authorized dealer as soon as possible to
have the problem diagnosed and corrected.
NOTE:
²9The9ESP/TCS Indicator Light9and the9ESP/BAS
Warning Lamp9come onmomentarilyeach time the
ignition switch is turned ON.
²Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
²The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.
REAR PARK ASSIST SYSTEMÐ IF EQUIPPED
The Rear Park Assist System provides visual and audible
indications of the distance between the rear fascia and the
detected obstacle when backing up. Refer to the Warning
Section and Note Section for limitations of this system
and recommendations.
The Rear Park Assist System will remember the last
system state (enabled or disabled) from the last ignition
cycle when the ignition is changed to the RUN/ON
position.
The Rear Park Assist System can be active only when the
shifter is in R (Reverse). If the Rear Park Assist System is
enabled at this shifter position, the system will be active
until the vehicle speed is increased to approximately 11
mph (18 km/h) or above. The system will be active again
if the vehicle speed is decreased to speeds less than
approximately 10 mph (16 km/h).

Rear Park Assist Sensors
The four Rear Park Assist Sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors' field of view. The monitored area seems oval
in shape.
The sensors can detect obstacles from approximately 11.8
inches (30 cm) up to 59 inches (150 cm) from the rear
fascia in the horizontal direction, depending on the
location and orientation of the obstacle and the type of
obstacle.
Rear Park Assist Warning Display
The Rear Park Assist Warning Display, located in the
headliner near the flipper glass, provides both visual and
audible warnings to indicate the distance between the
rear fascia and the detected obstacle.When the ignition is changed to the RUN/ON position,
the warning display will turn ON all of its LEDs for
about 1 second. Each side of the warning display has 6
yellow and 2 red LEDs. The vehicle is close to the obstacle
when the red LED is ON.Rear Park Assist Display

Cleaning the Rear Park Assist System
Clean the Rear Park Assist Sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. Do
not scratch or poke the sensors. Otherwise, you could
damage the sensors.
REAR CAMERA Ð IF EQUIPPED
Vehicles with a Navigation radio may be equipped with
a rear view camera (located on the rear liftgate) that
allows you to see an on-screen image (on the navigation
radio screen) of the rear of your vehicle whenever the
vehicle is put into R (Reverse).
WARNING!
Drivers must be careful when backing up even when
using the rear camera system. Always check carefully
behind your vehicle, and be sure to check for pedes-
trians, animals, other vehicles, obstructions, or blind
spots before backing up. Failure to do so can result in
serious injury or death.
If snow, ice, mud, or anything else builds up on the
camera lens. Clean the lens, rinse with water, and dry
with a soft cloth.

build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, braking
ability, and control.
²After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at very
slow speeds.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
