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.

WARNING! (Continued)
•Supplemental Side Air Bag Inflatable Curtain
(SABIC) and Seat-Mounted Side Air Bags (SAB)
also need room to inflate. Do not lean against the
door or window. Sit upright in the center of the
seat.
•In an accident, you and your passengers can suffer
much greater injuries if you are not properly
buckled up. You can strike the interior of your
vehicle or other passengers, or you can be thrown
out of the vehicle. Always be sure you and others
in your vehicle are buckled up properly.
Buckle up even though you are an excellent driver, even
on short trips. Someone on the road may be a poor driver
and cause an accident that includes you. This can happen
far away from home or on your own street.Research has shown that seat belts save lives, and they
can reduce the seriousness of injuries in an accident.
Some of the worst injuries happen when people are
thrown from the vehicle. Seat belts reduce the possibility
of ejection and the risk of injury caused by striking the
inside of the vehicle. Everyone in a motor vehicle should
be belted at all times.Lap/Shoulder Belts
All seating positions in your vehicle are equipped with
lap/shoulder belts. The belt webbing retractor is de-
signed to lock during very sudden stops or accidents.
This feature allows the shoulder part of the belt to move
freely with you under normal conditions. However, in an
accident the belt will lock and reduce the risk of you
striking the inside of the vehicle or being thrown out.

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.
•Unlock the doors automatically.

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

WARNING!
Do not ride with the seatback reclined so that the
shoulder belt is no longer resting against your chest.
In a collision you could slide under the seat belt,
which could result in serious injury or death.
DRIVER MEMORY SEAT — IF EQUIPPED
Once programmed, the memory buttons 1 and 2 on the
driver’s door panel can be used to recall the driver’s seat,
driver’s outside mirror, adjustable steering wheel posi-
tion (if equipped), and the radio station preset settings.
Your Remote Keyless Entry (RKE) transmitters can also
be programmed to recall the same positions when the
UNLOCK button is pressed.Your vehicle is equipped with two RKE transmitters. One
or both RKE transmitters can be linked to either memory
position. The memory system can accommodate up to
four RKE transmitters, each one linked to either of the
two memory positions.

This feature provides automatic driver’s seat positioning
which will enhance driver mobility out of and into the
vehicle.
There are two possible Easy Entry/Exit adjustments
available:
