Programming Transmitters to
the Vehicle
Only RKE transmitters programmed
to this vehicle will work. If a
transmitter is lost or stolen, a
replacement can be purchased and
programmed through your dealer/
retailer. When the replacement
transmitter is programmed to this
vehicle using the DIC, all remaining
transmitters must also be
reprogrammed. Any lost or stolen
transmitters will no longer work once
the new transmitter is programmed.
Each vehicle can have up to
eight transmitters programmed to it.
See “Relearn Remote Key” under
DIC Operation and Displays
(With DIC Buttons) on page 3-46or
DIC Operation and Displays
(Without DIC Buttons) on page 3-51
for instructions on how to program
transmitters to this vehicle.
Battery Replacement
Replace the battery if the REPLACE
BATTERY IN REMOTE KEY
message displays in the DIC.Notice:When replacing the
battery, do not touch any of the
circuitry on the transmitter. Static
from your body could damage
the transmitter.
1. Separate the transmitter with a
at, thin object inserted into the
notch on the side.
2. Remove the old battery. Do not
use a metal object.
3. Insert the new battery, positive
side facing down. Replace with
a CR2032 or equivalent battery.
4. Snap the transmitter back
together.
Remote Vehicle Start
This vehicle may have a remote
starting feature that starts the engine
from outside of the vehicle.
If the vehicle has an automatic
climate control system, the climate
control system defaults to a
heating or cooling mode depending
on the outside temperatures. If
the vehicle does not have an
automatic climate control system,
the system turns on at the
setting the vehicle was set to when
the vehicle was last turned off.
If the vehicle has an automatic
climate control system and heated
seats, the heated seats turn on
during colder outside temperatures
and shut off when the key is
turned to ON/RUN. SeeHeated
Seats on page 1-5orHeated and
Cooled Seats on page 1-6for
more information.

Liftgate
{CAUTION
Exhaust gases may enter the
vehicle if it is driven with the
liftgate, trunk/hatch open, or with
any objects that pass through the
seal between the body and the
trunk/hatch or liftgate. Engine
exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle must be driven with
the liftgate, or trunk/hatch open:
Close all of the windows.
Fully open the air outlets on
or under the instrument
panel.
(Continued)
CAUTION (Continued)
Adjust the Climate Control
system to a setting that
brings in only outside air and
set the fan speed to the
highest setting. See Climate
Control System in the Index.
If the vehicle is equipped with
a power liftgate, disable the
power liftgate function.
For more information about
carbon monoxide, seeEngine
Exhaust on page 2-30.
If the vehicle has a power liftgate,
seePower Liftgate on page 2-11.
To unlock the liftgate, use the power
door lock switch or press the door
unlock button on the Remote
Keyless Entry (RKE) transmitter
twice. SeeRemote Keyless Entry
(RKE) System Operation on
page 2-3.To open the liftgate, press the
touchpad on the underside of the
liftgate handle. The vehicle must be
in P (Park) to open the liftgate.
To close the liftgate, use the pull cup
or pull strap as an aid.
The liftgate has an electric latch. If
the battery is disconnected or
has low voltage, the liftgate will not
open. The liftgate will resume
operation when the battery is
reconnected and charged.
If the battery is properly connected
and has adequate voltage, and
the liftgate still will not function, the
vehicle should be taken to a
dealership/retailer for service.

The vehicle may have a power
liftgate. The vehicle must be
in P (Park) to use the power feature.
The taillamps will ash and a
chime will sound when the power
liftgate is used.
{CAUTION
You or others could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
Notice:If you open the liftgate
without checking for overhead
obstructions such as a garage
door, you could damage the
liftgate or the liftgate glass.
Always check to make sure the
area above and behind the liftgate
is clear before opening it.
The power liftgate can be
power opened and closed in the
following ways:
Press and hold the power liftgate
button on the Remote Keyless

page 3-46andDIC Operation and
Displays (With DIC Buttons) on
page 3-46orDIC Operation and
Displays (Without DIC Buttons) on
page 3-51for more information. The
number displayed in the DIC is the
highest gear that the transmission
will be allowed to operate in. This
means that all gears below that
number are available. For example,
when 4 (Fourth) is shown next to
the L, 1 (First) through 4 (Fourth)
gears are automatically shifted by
the vehicle. The transmission will not
shift into 5 (Fifth) until the + (Plus)
button is used or you shift back into
D (Drive).
While in L (Low), the transmission
will prevent shifting to a lower
gear range if the engine speed is
too high. You have a brief period of
time to slow the vehicle. If vehicle
speed is not reduced within the time
allowed, the lower gear range
shift will not be completed. You must
further slow the vehicle, then
press the−(Minus) button to the
desired lower gear range.Automatic Engine Grade braking is
not available when the ERS is
active. It is available in D (Drive) for
both normal and Tow/Haul mode.
While using the ERS, cruise control
and the tow/haul mode can be
used. SeeTow/Haul Mode
on page 2-26for more information.
Tow/Haul Mode
_
(Tow/Haul):The vehicle may
have a Tow/Haul mode.
The button is located on the
instrument panel under the climate
controls.
Push the button to activate the
system. Push it again to deactivate
the system. You can use this
feature to assist when towing or
hauling a heavy load.
When Tow/Haul is activated the
Tow/Haul symbol will come on the
instrument panel cluster. See
“Tow/Haul Mode” underTowing a
Trailer on page 4-24for more
information.
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.
2-26 Features and Controls

This feature can be turned on or off
through the Driver Information
Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons)
on page 3-64andMemory 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

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.
