Automatic Engine Grade
Braking
Automatic Engine Grade Braking
assists when driving on a downhill
grade. It maintains vehicle speed by
automatically implementing a shift
schedule that uses the engine and
the transmission to slow the vehicle.
The system will automatically
command downshifts to reduce
vehicle speed, until the brake pedal
is no longer being pressed.
While in the Electronic Range
Select (ERS) mode, grade braking
is deactivated, allowing the
driver to select a range and limiting
the highest gear available. Grade
braking is available for normal
driving and in Tow/Haul mode.
SeeAutomatic Transmission
Operation on page 2-24.
Parking Brake
To set the parking brake, hold the
regular brake pedal down, then push
the parking brake pedal down.
If the ignition is on, the brake system
warning light will come on. See
Brake System Warning Light
on page 3-33.Notice:Driving with the parking
brake on can overheat the
brake system and cause
premature wear or damage to
brake system parts. Make
sure that the parking brake is
fully released and the brake
warning light is off before driving.
To release the parking brake,
hold the regular brake pedal down,
then push down momentarily on
the parking brake pedal until
you feel the pedal release. Slowly
pull your foot up off the park
brake pedal. If the parking brake is
not released when you begin to
drive, the brake system warning light
will be on and a chime will sound
warning you that the parking
brake is still on.
If you are towing a trailer and are
parking on a hill, seeTowing a
Trailer on page 4-24.

Automatic Dimming Mirror
Operation
Automatic dimming reduces the
glare from the headlamps of
the vehicle behind you. The dimming
feature comes on and the indicator
light illuminates each time the
ignition is turned to start.
Cleaning the Mirror

located on the control pad to
adjust the mirror.3. Adjust each outside mirror to see
a little of your vehicle, and the
area behind your vehicle.
4. Press either (A) or (B) again to
deselect the mirror.
Manually fold the mirrors inward to
prevent damage when going
through an automatic car wash.
To fold, push the mirror toward the
vehicle. Push the mirror outward,
to return it to the original position.
Using hood-mounted air deectors
and add-on convex mirror
attachments could decrease mirror
performance.

indicator lamp that is built into
the mirror housing. The turn signal
lamp ashes with the use of the
vehicle’s turn signal and hazard
ashers.
2-32 Features and Controls

{CAUTION
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
objects that are below the
bumper, underneath the
vehicle, or if they are too
close or far from the vehicle
children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before and while backing; vehicle
damage, injury, or death could
occur. Even with URPA, always
check behind the vehicle before
backing up. While backing, be
sure to look for objects and check
the vehicle’s mirrors.The display is located in the
headliner and can be seen by
looking over your right shoulder.
URPA uses three color-coded lights
to provide distance and system
information.How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). The rear display briey
illuminates to indicate the system
is working.URPA operates only at speeds less
than 5 mph (8 km/h). If the vehicle
is above this speed, the red light on
the rear display will ash.
To be detected, objects must be at
least 10 inches (25.4 cm) off the
ground and below liftgate level.
Objects must also be within 8 feet
(2.5 m) from the rear bumper.
This distance may be less during
warmer or humid weather.
A single beep will sound the rst
time an object is detected. Beeping
may occur beginning at 23 inches
(0.6 m). Beeping will occur for
a short time when the vehicle is
closer than 1 foot (0.3 m) from
the object.
Features and Controls 2-35

The following describes how the URPA display lights appear as the vehicle
gets closer to a detected object:
DescriptionEnglishMetric
amber light 8 ft2.5 m
amber/amber lights 40 in1.0 m
amber/amber/red lights 23 in0.6 m
amber/amber/red lights ashing 1 ft 0.3 m
The system can be disabled through
the Driver Information Center (DIC).
See “Park Assist” under DIC
Operation and Displays on
page 3-41 for more information.
When the System Does
Not Seem to Work Properly
If the URPA system will not activate
due to a temporary condition, the
message PARK ASSIST OFF will be
displayed on the DIC and a red light
will be shown on the rear URPA display when the shift lever is
moved into R (Reverse). This may
occur under the following
conditions:
The driver disables the system.
The parking brake pedal is
depressed.
The ultrasonic sensors are not
clean. Keep the vehicle’s rear
bumper free of mud, dirt,
snow, ice and slush. For cleaning
instructions, see
Washing Your
Vehicle on page 5-86 .
A trailer was attached to the
vehicle, or a bicycle or an
object was hanging out of the
liftgate during the last drive cycle,
the red light may illuminate in
the rear display. Once the
attached object is removed,
URPA will return to normal
operation.
A tow bar is attached to the
vehicle.
The vehicle’s bumper is
damaged. Take the vehicle to
your dealer/retailer to repair
the system.
Other conditions may affect
system performance, such
as vibrations from a jackhammer
or the compression of air
brakes on a very large truck.
If the system is still disabled, after
driving forward at least 15 mph
(25 km/h), take the vehicle to your
dealer/retailer.

Rear Vision
Camera (RVC)
This vehicle may have a Rear
Vision Camera system. Read this
entire section before using it.
{CAUTION
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
Detect objects that are
outside the camera’s eld of
view, below the bumper, or
underneath the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
(Continued)
CAUTION (Continued)
Do not back the vehicle by only
looking at the rear vision camera
screen, or use the screen during
longer, higher speed backing
maneuvers or where there could
be cross-traffic. Your judged
distances using the screen will
differ from actual distances.
So if you do not use proper care
before backing up, you could hit a
vehicle, child, pedestrian, bicyclist,
or pet, resulting in vehicle
damage, injury, or death. Even
though the vehicle has the RVC
system, always check carefully
before backing up by checking
behind and around the vehicle.
Vehicles Without Navigation
System
The rear vision camera system is
designed to help the driver when
backing up by displaying a view of
the area behind the vehicle. When
the driver shifts the vehicle into
R (Reverse), the video image
automatically appears on the inside
rear view mirror. Once the driver
shifts out of R (Reverse), the video
image automatically disappears from
the inside rear view mirror after a
short delay.

The back of the vehicle is in
an accident, the position and
mounting angle of the camera
can change or the camera can be
affected. Be sure to have the
camera and its position and
mounting angle checked at your
dealer/retailer.
There are extreme temperature
changes.
The rear vision camera system
display in the rearview mirror may
turn off or not appear as expected
due to one of the following
conditions. If this occurs the left
indicator light on the mirror will ash.
A slow ash may indicate a
loss of video signal, or no
video signal present during the
reverse cycle.
A fast ash may indicate that the
display has been on for the
maximum allowable time during a
reverse cycle, or the display has
reached an Over Temperature
limit.
The fast ash conditions are
used to protect the video device
from high temperature conditions.
Once conditions return to
normal the device will reset and
the green indicator will stop
ashing.
During any of these fault conditions,
the display will be blank and the
indicator will continue to ash
as long as the vehicle is in
R (Reverse) or until the conditions
return to normal.
Briey pressing
zwhen the left
indicator light is ashing will turn off
