Do not attempt sharp turns, abrupt maneuvers,
or other unsafe driving actions that can cause
loss of vehicle control. Failure to operate this
vehicle safely may result in a collision, rollover
of the vehicle, and severe or fatal injury. Drive
carefully.Failure to use the driver and passenger seat
belts
provided is a major cause of severe or
fatal injury. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt. Always buckle up.

NOTE:
You can insert the double-sided emergency
key into the lock cylinders with either side
up.
Removing Key Fob From IgnitionPlace the shift lever in PARK. Turn the Key Fob
to the OFF position and then remove the Key
Fob.
With the Keyless Enter-N-Go feature, the EVIC
will display the ignition switch position “OFF/
ACC/RUN”. Refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.NOTE:
•
If you try to remove the Key Fob before
you place the shift lever in PARK, it may
become trapped temporarily in the igni-
tion switch. If this occurs, rotate the key
to the right slightly, then remove the Key
Fob as described. If a malfunction occurs,
the system may trap the key in the igni-
tion switch to warn you that this safety
feature is inoperable. The engine can be
started and stopped, but the Key Fob
cannot be removed until you obtain ser-
vice.
• The power window switches, radio, power
sunroof (if equipped), and power outlets
will remain active for up to 10 minutes
after the ignition switch is turned to the
LOCK position. Opening either front door
will cancel this feature. The time for this
feature is programmable. Refer to “Elec-
tronic Vehicle Information Center (EVIC)/
Personal Settings (Customer-Program-
mable Features)” in “Understanding Your
Instrument Panel” for further information.
WARNING!
• Never leave children alone in a vehicle.
Leaving unattended children in a vehicle is
dangerous for a number of reasons. A child
or others could be seriously or fatally in-
jured. Do not leave the Key Fob in the
ignition or Keyless Enter-N-Go in the ACC
or ON/RUN mode. A child could operate
power windows, other controls, or move the
vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
An unlocked car is an invitation to thieves.
Always remove Key Fob from the ignition and
lock all doors when leaving the vehicle unat-
tended.
Emergency Key Removal
13

Key-In-Ignition ReminderOpening the driver’s door when the Key Fob is
in the ignition and the ignition switch position is
OFF or ACC, sounds a signal to remind you to
remove the Key Fob.
NOTE:
The Key-In-Ignition reminder only sounds
when the Key Fob is placed in the OFF or
ACC ignition position.
With the Keyless Enter-N-Go feature, opening
the driver’s door when the vehicle’s ignition
switch is placed in ACC or ON/RUN (engine
stopped) will cause the reminder chime to
sound. Refer to “Starting Procedures” in “Start-
ing And Operating” for further information.
SENTRY KEYThe Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling
the engine. The system does not need to be
armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or
unlocked. The system uses the factory-mated Key Fob
with Remote Keyless Entry (RKE) transmitter
and Wireless Ignition Node (WIN) to prevent
unauthorized vehicle operation. Therefore, only
Key Fobs that are programmed to the vehicle
can be used to start and operate the vehicle.
The system will shut the engine off in two
seconds if an invalid Key Fob is used to start
the engine.
After turning the ignition switch to the ON/RUN
position, the Vehicle Security Light will turn on
for three seconds for a bulb check. If the light
remains on after the bulb check, it indicates
that there is a problem with the electronics. In
addition, if the light begins to flash after the
bulb check, it indicates that someone used an
invalid Key Fob to start the engine. Either of
these conditions will result in the engine being
shut off after two seconds.
If the Vehicle Security Light turns on during
normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there
is a fault in the electronics. Should this occur,
have the vehicle serviced as soon as possible
by an authorized dealer.
CAUTION!
The Sentry Key
Immobilizer system is not
compatible with some after-market remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.
All of the Key Fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
Replacement Keys
NOTE:
Only Key Fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a Key Fob is
programmed to a vehicle, it cannot be pro-
grammed to any other vehicle.
CAUTION!
• Always remove the Key Fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.

pending on the severity and type of collision. In
these events, the ORC will deploy the SABIC
only on the impact side of the vehicle.
A quantity of non-toxic gas is generated to
inflate the side curtain airbag. The inflating side
curtain airbag pushes the outside edge of the
headliner out of the way and covers the win-
dow. The airbag inflates in about 30 ms (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 side curtain
airbag inflates. This especially applies to chil-
dren. The side curtain airbag is only about
3-1/2 in (9 cm) thick when it is inflated.
Because airbag sensors estimate deceleration
over time, vehicle speed and damage are not
good indicators of whether or not an airbag
should have deployed.
NOTE:
In a rollover the pretensioners, and/or SAB
and SABIC airbags may deploy on both
sides of the vehicle.Front and Side Impact Sensors
In front and side impacts, impact sensors can
aid the ORC in determining appropriate re-
sponse to impact events. Additional sensors in
the ORC determine the level of airbag deploy-
ment and provide verification.
Enhanced Accident Response System
In the event of an impact causing airbag de-
ployment, if the communication network re-
mains 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. If a Deployment Occurs
The Advanced Front Airbags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side airbags will not deploy in
all collisions. This does not mean some-
thing is wrong with the airbag system.
If you do have a collision which deploys the
airbags, any or all of the following may occur:
•
The nylon airbag material may sometimes
cause abrasions and/or skin reddening to
the driver and front passenger as the air-
bags deploy and unfold. The abrasions are
similar to friction rope burns or those you
might get sliding along a carpet or gymna-
sium floor. They are not caused by contact
with chemicals. They are not permanent and
normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.

WARNING!
•An incorrectly anchored tether strap could
lead to increased head motion and possible
injury to the child. Use only the anchor
positions directly behind the child seat to
secure a child restraint top tether strap.
• Do not use the cargo tie downs located on
the load floor. Improper usage of the tether
can lead to a failure of an infant or child
restraint. The child could be badly injured
or killed. Transporting Pets
Airbags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown
about and possibly injured, or injure a passen-
ger during panic braking or in an accident. Pets
should be restrained in the rear seat in pet
harnesses or pet carriers that are secured by
seat belts.
ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle) in
your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws, contributes
to a good break-in. Wide-open throttle accel-
eration in low gear can be detrimental and
should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving type
lubricant. Oil changes should be consistent
with anticipated climate conditions under
which vehicle operations will occur. For the
recommended viscosity and quality grades re-
fer to “Maintenance Procedures” in “Maintain-
ing Your Vehicle”. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera-
tion. This should be considered a normal part
of the break-in and not interpreted as an indi-
cation of difficulty.
Additional Requirements For Diesel
Engine — If Equipped
During the first 1500 km avoid heavy loads, e.g.
driving at full throttle. Do not exceed 2/3 of the
maximum permissible engine speed for each
gear. Change gear in good time. Do not shift
down a gear manually in order to brake.

SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
WARNING!
•Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
• It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing (CO) follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate
open, make sure that all windows are closed
and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation
mode. The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas
for broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.

WARNING!(Continued)
• Never put floor mats or other floor cover-
ings on top of already installed floor mats.
Additional floor mats and other coverings
will reduce the size of the pedal area and
interfere with the pedals.
• Check mounting of mats on a regular basis.
Always properly reinstall and secure floor
mats that have been removed for cleaning.
• Always make sure that objects cannot fall
into the driver foot well while the vehicle is
moving. Objects can become trapped un-
der the brake pedal and accelerator pedal
causing a loss of vehicle control.
(Continued)WARNING!(Continued)
• If required, mounting posts must be prop-
erly installed, if not equipped from the fac-
tory.
Failure to properly follow floor mat installation
or mounting can cause interference with the
brake pedal and accelerator pedal operation
causing loss of control of the vehicle.
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.
Inspect the tread and sidewall for cuts and
cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper
pressure. Lights
Have someone observe the operation of exte-
rior 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 lock-
ing.
Fluid Leaks
Check area under vehicle after overnight park-
ing 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.
