{Warning
If the key is unintentionally
rotated while the vehicle is
running, the ignition could be
moved out of the RUN position.
This could be caused by heavy
items hanging from the key ring,
or by large or long items attached
to the key ring that could be
contacted by the driver or
steering wheel. If the ignition
moves out of the RUN position,
the engine will shut off, braking

impacted, and airbags may not
deploy. To reduce the risk of
unintentional rotation of the
ignition key, do not change the
way the ignition key and Remote
Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
The ignition key, key rings, and RKE
transmitter, if equipped, are
designed to work together. As a
system, it reduces the risk of
unintentionally moving the key out
of the RUN position. If replacements
or additions are required, see your
dealer. Limit added items to a few
essential keys or small, light items
no larger than an RKE transmitter.
Interference from radio-frequency
identification (RFID) tags may
prevent the key from starting the
vehicle. Keep RFID tags away from
the key when starting the vehicle.
The key that is part of the Remote
Keyless Entry (RKE) transmitter can
be used for the ignition and all
locks.

Manual Operation of Power
Liftgate
To change the liftgate to manual
operation, turn the mode switch to
the OFF position.
Caution
Attempting to move the liftgate
too quickly and with excessive
force may result in damage to the
vehicle.
With the power liftgate disabled and
all of the doors unlocked, the liftgate
can be manually opened and
closed. Manual operation of a
liftgate that also has power
operation requires more effort than
a standard manual liftgate. To open the liftgate, press the touch
pad under the liftgate handle and lift
up. To close the liftgate, use the pull
cup to lower the liftgate and close.
With the power liftgate disabled, the
liftgate electric latch will still power
latch once contact is made with the
striker. Always close the liftgate
before driving.
IfYon the RKE transmitter is
pressed while power operation is
disabled, the turn signals flash and
the liftgate will not move.
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.
Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
the vehicle impossible to steal.
Vehicle Alarm System
This vehicle has an anti-theft alarm
system.
The indicator light, on the
instrument panel near the
windshield, indicates the status of
the system:

3. Push the latch plate into thebuckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the
belt is not long enough, see
Safety Belt Extender 060.
Position the release button on
the buckle so that the safety
belt could be quickly unbuckled
if necessary.
4. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
later in this section for
instructions on use and
important safety information.
5. To make the lap part tight, pullup on the shoulder belt.
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
Always stow the safety belt slowly.
If the safety belt webbing returns
quickly to the stowed position, the
retractor may lock and cannot be
pulled out. If this happens, pull the
safety belt straight out firmly to
unlock the webbing, and then
release it. If the webbing is still
locked in the retractor, see your
dealer.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
front outboard passenger seating
positions.
Adjust the height so the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt
should be close to, but not
contacting, the neck. Improper

66 Seats and Restraints
For airbag locations, seeWhere Are
the Airbags? 063.
How Does an Airbag
Restrain?
In moderate to severe frontal or
near frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact
the inside of the vehicle.
Airbags supplement the protection
provided by safety belts by
distributing the force of the impact
more evenly over the
occupant's body.
Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in the
outboard seating positions in the
first and second rows. The rollover
capable roof-rail airbags are
designed to help reduce the risk of
full or partial ejection in rollover
events, although no system can
prevent all such ejections. But airbags would not help in many
types of collisions, primarily
because the occupant's motion is
not toward those airbags. See
When
Should an Airbag Inflate? 065.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See after
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they inflate. Some components of
the airbag module may be hot for
several minutes. For location of the
airbags, see Where Are the
Airbags? 063.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{Warning
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the
fuel system after the airbags inflate.

88 Seats and Restraints
Armrest Retaining Strap
{Warning
A rear center armrest that is not
properly stowed and secured
could fall forward during a sudden
stop or collision. The armrest
could contact an infant secured in
a rear‐facing child restraint in the
center seat position. Fasten the
retaining strap onto the stowed
armrest before installing a rear‐
facing child restraint in the rear
center seat position.
When new, the vehicle's glove box
materials included an armrest
retaining strap. Use it to secure the
center armrest before installing a
rear-facing child restraint in the
second row center seat position.
Stow the rear seat center armrest.
Attach the retaining strap to the
armrest loop (1) and to the center
top tether anchor on the
seatback (2). Make sure the
retaining strap's clips are firmly
attached.
Install the rear-facing child restraint
using the child restraint
manufacturer's instructions and the
instructions described previously.
Remove the armrest retaining strap
before installing a forward facing
child restraint in the center seat
position, as it may interfere with the
attachment of the top tether to the
top tether anchor on the seatback.
Securing Child Restraints
(With the Safety Belt in
the Front Seat)
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint079.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag
under certain conditions. See
Passenger Sensing System 067
and Passenger Airbag Status
Indicator 0106 for more information,
including important safety
information.
Never put a rear-facing child seat in
the front. This is because the risk to
the rear-facing child is so great,
if the airbag deploys.

152 Driving and Operating
See specific vehicle steering
messages underService Vehicle
Messages 0123.
Hydraulic Power Steering (3.6L
V6 Engine)
If your vehicle has hydraulic power
steering, it may require
maintenance. See Power Steering
Fluid (2.4L L4 Engine) 0220 or
Power Steering Fluid (3.6L
V6 Engine) 0220.
If power steering is lost because the
engine stops or a system
malfunctions, the vehicle can be
steered but may require increased
effort. See your dealer if there is a
problem.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
for more than 15 seconds,
damage may occur to the power
steering system and there may be
loss of power steering assist.
Curve Tips
. Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking.
. Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. Anti-lock Brake System (ABS)
allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
1. Ease off the accelerator and then, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
