Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Notice:Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage
the transmission. Shift to P (Park)
only when the vehicle is stopped.
Starting Procedure
1. With your foot off the
accelerator pedal, turn the
ignition to START. When the
engine starts, let go of the key.
The idle speed will slow down
as the engine warms. Do not
race the engine immediately after
starting it. Operate the engine
and transmission gently to allow
the oil to warm up and lubricate
all moving parts.The vehicle has a
Computer-Controlled
Cranking System. This feature
assists in starting the engine
and protects components.
If the ignition key is turned to
the START position, and
then released when the engine
begins cranking, the engine
will continue cranking for a
few seconds or until the vehicle
starts. If the engine does not
start and the key is held in
START, cranking will be stopped
after 15 seconds to prevent
cranking motor damage.
To prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch
to the ACC/ACCESSORY
or LOCK/OFF position.Notice:Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start
after 5-10 seconds, especially
in very cold weather (below 0°F
or−18°C), it could be ooded
with too much gasoline.
Try pushing the accelerator
pedal all the way to the oor
and holding it there as you hold
the key in START for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts, let go
of the key and accelerator.

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 3-36.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 4-26.

Park Tilt Mirrors
If the vehicle has the memory
package, the outside mirrors have a
park tilt feature. This feature tilts
the outside mirrors to a preselected
position when the vehicle is in
R (Reverse). This allows the driver
to view the curb for parallel parking.
The passenger and/or driver
mirror returns to its original position
when the vehicle is shifted out of
R (Reverse), or the ignition is
turned off or to OFF/LOCK.
This feature can be turned on or off
through the Driver Information
Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons)
on page 3-65andMemory Seat
and Mirrors on page 1-6for more
information.
Outside Convex Mirror
{CAUTION
A convex mirror can make things
(like other vehicles) look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror’s surface
is curved so more can be seen from
the driver seat.
Outside Heated Mirrors
For vehicles with heated mirrors:
<(Rear Window Defogger):
Press to heat the mirrors.
See “Rear Window Defogger” under
Dual Automatic Climate Control
System on page 3-22for more
information.
Object Detection
Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it operates at speeds less than
5 mph (8 km/h), and assists the
driver with parking and avoiding
objects while in R (Reverse).
The sensors on the rear bumper are
used to detect the distance to an
object up to 8 feet (2.5 m) behind
the vehicle, and at least 10 inches
(25.4 cm) off the ground.
2-34 Features and Controls
ProCarManuals.com

{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 brie y
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 ashes.
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 sounds the rst time
an object is detected. Beeping
may occur beginning at 23 inches
(0.6 m). Beeping occurs for a
short time when the vehicle is closer
than 23 inches (0.6 m) and again
at 1 foot (0.3 m) from the object.

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
(With DIC Buttons) on page 3-45
or DIC Operation and Displays
(Without DIC Buttons) on page 3-50
for more information.
When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message PARK ASSIST OFF displays 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 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 5-87 .
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.
