Preventing Inadvertent Locking Of Passive Entry RKE
Transmitter In Vehicle
To minimize the possibility of unintentionally locking a
Passive Entry RKE transmitter inside your vehicle, the
Passive Entry system is equipped with an automatic door
unlock feature which will function if there is no Key Fob
present in the ignition.
If one of the vehicle doors is open and the door panel
switch is used to lock the vehicle, once all open doors
have been closed the vehicle checks the inside and
outside of the vehicle for any valid Passive Entry RKE
transmitters. If one of the vehicle’s Passive Entry RKE
transmitters is detected inside the vehicle, and no other
valid Passive Entry RKE transmitters are detected out-
side the vehicle, the Passive Entry System automatically
unlocks all vehicle doors and chirps the horn three times
(on the third attempt ALL doors will lock and the Passive
Entry RKE transmitter can be locked in the vehicle).To Enter The Liftgate
With a valid Passive Entry RKE transmitter within 3 ft
(1.0 m) of the liftgate, press the button on the right side of
the chrome accent bar, which is located on the liftgate
below the flipper glass to lock or unlock the vehicle.

WARNING!
Never leave children in a vehicle with the key in the
ignition switch or leave a vehicle with Keyless Enter-
N-Go in the ACC or ON/RUN position. Occupants,
particularly unattended children, can become en-
trapped by the windows while operating the power
window switches. Such entrapment may result in
serious injury or death.
Auto-Down
Both the driver and front passenger window switches
have an “Auto-Down” feature. Press the window switch
past the first detent, release, and the window will go
down automatically. To cancel the “Auto-Down” move-
ment, operate the switch in either the up or down
direction and release the switch.
To open the window part way, press to the first detent
and release it when you want the window to stop.The power window switches remain active for 10 min-
utes after the ignition has been turned OFF. Opening
either front door will cancel this feature.
Auto Up Feature With Anti-Pinch Protection —
Driver And Front Passenger Door Only
Lift the window switch fully upward to the second
detent, release, and the window will go up automatically.
To stop the window from going all the way up during the
Auto Up operation, push down on the switch briefly.
To close the window part way, lift the window switch to
the first detent and release when you want the window to
stop.
NOTE:
If the window runs into any obstacle during
Auto Up it will reverse direction and then go back down.
Remove the obstacle and use the window switch again to
close the window. Any impact due to rough road condi-
tions may trigger the auto reverse function unexpectedly

Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the sunroof open, adjust the sunroof opening to minimize
the buffeting.
LIFTGATE
To open the liftgate, pull up on the handle and lift.
Manually unlocking the vehicle doors with the plunger
or a key in the lock cylinder will not unlock the liftgate.
WARNING!
Driving with the liftgate open can allow poisonous
exhaust gases into your vehicle. You and your pas-
sengers could be injured by these fumes. Keep the
liftgate closed when you are operating the vehicle.

Power Liftgate — If Equipped
The power liftgate may be opened by pulling
up on the liftgate handle or by pressing the
LIFTGATE button on the Remote Keyless Entry
(RKE) transmitter. Press the LIFTGATE button
on the RKE transmitter twice within five seconds, to open
the power liftgate. Once the liftgate is open, pressing the
button twice within five seconds a second time will close
the liftgate.
The power liftgate may also be opened or closed by
pressing the LIFTGATE button located on the front
overhead console, or closed by pressing the LIFTGATE
button located on the left rear trim, near the liftgate
opening. Pressing the LIFTGATE button located on left
rear trim once will close the liftgate only, this button
cannot be used to open the liftgate. To operate the power liftgate manually in the open
direction, pull the liftgate handle once to initiate a power
cycle and then pull the handle a second time to put
liftgate into manual mode.
When the LIFTGATE button on the RKE transmitter is
pressed two times, the turn signals will flash twice to
signal that the liftgate is opening or closing (if Flash
Lamps with Lock is enabled in the EVIC) and the liftgate
chime will be audible. For further information, refer to
Customer-Programmable Features (System Setup)/
Electronic Vehicle Information Center (EVIC)
in Under-
standing Your Instrument Panel.
NOTE: In the event of a power malfunction to the
liftgate, an emergency liftgate latch release can be used to
open the liftgate. The emergency liftgate latch release can
be accessed through a snap-in cover located on the
liftgate trim panel.

WARNING!
During power operation, personal injury or cargo
damage may occur. Ensure the liftgate travel path is
clear. Make sure the liftgate is closed and latched
before driving away.
NOTE:
•The power liftgate will not operate if the liftgate
flipper glass is open.
•The power liftgate buttons will not operate if the
vehicle is in gear or the vehicle speed is above 0 mph
(0 km/h).
•The power liftgate will not operate in temperatures
below 22°F (30°C) or temperatures above 150°F
(65°C). Be sure to remove any buildup of snow or ice
from the liftgate before pressing any of the power
liftgate switches.
•If anything obstructs the power liftgate while it is
closing or opening, the liftgate will automatically
reverse to the closed or open position, provided it
meets sufficient resistance.
•There are also pinch sensors attached to the side of the
liftgate. Light pressure anywhere along these strips
will cause the liftgate to return to the open position.
•The power liftgate must be in the full open position for
rear liftgate close button on the left rear trim, near the
liftgate opening to operate. If the liftgate is not fully
open, press the Liftgate button on the Key Fob to fully
open the liftgate, and then press it again to close.
•If the liftgate handle is pulled while the power liftgate
is closing, the liftgate will reverse to the full open
position.

Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal collisions depending on the severity and
type of collision. Advanced Front Air Bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions.
The Advanced Front Air Bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions. On
the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.
The side air bags will not deploy in all side collisions.
Side air bag deployment will depend on the severity and
type of collision.Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the key is in the OFF
position, in the ACC position, or not in the ignition, the
air bag system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.

A quantity of non-toxic gas is generated to inflate the
SABIC. The inflating SABIC pushes the outside edge of
the headliner out of the way and covers the window. The
SABIC inflates in about 30 milliseconds (about one-
quarter of the time that it takes to blink your eyes) with
enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the SABIC inflates. This especially applies to
children. The SABIC is only about 3-1/2 in (9 cm) thick
when it is inflated.
Because air bag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an air bag should have deployed.
NOTE:In a rollover the pretensioners and/or SAB and
SABIC air bags may deploy on both sides of the vehicle.Front And Side Impact Sensors
In front and side impacts, front and side impact sensors
can aid the ORC in determining the appropriate response
to certain impact events.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
