Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They
use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or
information relating to a specic component,
control, message, gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

reaches the desired level of lumbar support.
Keep in mind that as your seating position
changes, as it may during long trips, so should the
position of your lumbar support. Adjust the seat
as needed.
Heated Seats
On vehicles with heated front seats the controls
are located on the center console near the climate
controls. To operate the heated seats the
ignition must be on.
I(Heated Seatback):Press this button to turn
on the heated seatback.

4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle. It may also start up
the vehicle’s heating or air conditioning systems
and rear window defogger. Normal operation of the
system will return after the key is turned to the
ON position.
If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate control
system, during remote start, the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.During a remote start, if your vehicle has an
automatic climate control system and heated
seats, the heated seats will turn on during colder
outside temperatures and will shut off when
the key is turned to RUN. If your vehicle does not
have an automatic climate control system,
during remote start, you will need to manually turn
the heated seats on and off. See Heated Seats
for additional information
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using the remote start to have the
vehicle in view when doing so. Check local
regulations for any requirements on remote starting
of vehicles.
The RKE transmitter with the remote start button,
provides an increased range of operation. However,
the range may be less while the vehicle is running.
As a result, you may need to be closer to your
vehicle to turn it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 98for
additional information.

Liftgate
{CAUTION:
It can be dangerous to drive with the
liftgate open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death.
If you must drive with the liftgate open, or
if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
SeeClimate Control System on
page 199.
CAUTION: (Continued)
CAUTION: (Continued)

If you have air outlets on or under
the instrument panel, open them all
the way.
If your vehicle has a power liftgate,
disable the power liftgate function.
SeePower Liftgate on page 110.
If your vehicle has a power liftgate, seePower
Liftgate on page 110.
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 100.
To open the liftgate, press the touchpad on the
underside of the liftgate handle. The vehicle must
be in PARK (P) to open the liftgate. To close
the liftgate, use the pull cup or pull strap as an aid.
109

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, your vehicle should be taken to a
dealership for service.

Tow/Haul Mode
Your vehicle may have a Tow/Haul mode.
The button to turn it on
or off is located on
instrument panel under
the climate controls.
Push the button to turn it on, 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 ModeunderTowing a Trailer on
page 371for more information.
Automatic Engine Grade Braking
Automatic Engine Grade Braking assists when
driving on a downhill grade. It maintains the
vehicle’s speed by automatically implementing a
shift schedule that uses the engine and the
transmission to slow the vehicle. This reduces
wear on the brakes system and increases control
of the vehicle. The system constantly monitors
the vehicle’s speed, acceleration, throttle position,
and whether the brake pedal is being pressed,
and determines when to keep the current vehicle
speed or to slow down. The system will then
automatically command downshifts that reduces
the vehicle’s speed, until the brake pedal is
no longer being pressed. This indicates the desired
vehicle speed has been reached.
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 129.

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 138.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 356.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your vehicle when the engine is running
unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
always set the parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 135.
If you are pulling a trailer, seeTowing a Trailer on
page 371.

Outside Heated Mirrors
Press the rear window defogger button, located on
the climate control panel, to also turn the outside
heated mirrors on or off. The mirrors will heat to
help clear fog or frost from the surface of the mirror.
