Ignition Positions
The ignition switch has four different
positions.
In order to shift out of P (Park), the
ignition must be in ON/RUN or
ACC/ACCESSORY and the brake
pedal must be applied.Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct key,
make sure it is all the way in, and
turn it only with your hand. If the
key cannot be turned by hand,
see your dealer/retailer.
((LOCK/OFF):This position
locks the ignition and transmission.
The key can be removed in
LOCK/OFF.
The shift lever must be in P (Park)
to turn the ignition switch to
LOCK/OFF.
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from right to left while turning
the key to ACC/ACCESSORY.
If this doesn’t work, then the vehicle
needs service.ACC (ACC/ACCESSORY):This is
the position in which you can
operate the electrical accessories or
items plugged into the accessory
power outlets. This position unlocks
the ignition and steering wheel.
Use this position if the vehicle must
be pushed or towed.R(ON/RUN):This position can be
used to operate the electrical
accessories and to display some
instrument panel warning and
indicator lights. The switch stays in
this position when the engine is
running. The transmission is also
unlocked in this position. If you leave
the key in the ACC/ACCESSORY or
ON/RUN position with the engine off,
the battery could be drained. You
may not be able to start the vehicle if
the battery is allowed to drain for an
extended period of time.
/(START):This is the position
that starts the engine. When
the engine starts, release the key.
The ignition switch will return to
ON/RUN for driving.

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.
Features and Controls 2-27

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.

where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.The cruise control buttons are
