{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 and steering power assist may be
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 and key rings, and RKE
transmitter, if equipped, are designed to
work together as a system to reduce the
risk of unintentionally moving the key out
of the RUN position. The ignition key has a
small hole to allow attachment of the
provided key ring. It is important that any replacement ignition keys have a small hole.
See your dealer if a replacement key is
required.
The combination and size of the rings that
came with your keys were specifically
selected for your vehicle. The rings are
connected to the key like two links of a
chain to reduce the risk of unintentionally
moving the key out of the RUN position. Do
not add any additional items to the ring
attached to the ignition key. Attach
additional items only to the second ring,
and 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 is used for the ignition and all door
locks.
Programming Keys
Follow these procedures to program up to
eight keys to the vehicle.

If a key is lost or damaged, see your dealer
to have a new key made.
Programming without Two Recognized Keys
Program a new key to the vehicle when a
recognized key is not available. Canadian
regulations require that owners see their
dealer.
If two currently recognized keys are not
available, follow this procedure to program
the first key. This procedure will take approximately
30 minutes to complete for the first key.
The vehicle must be off and all of the keys
you wish to program must be with you.
1. Insert the new vehicle key into the ignition.
2. Turn the ignition on. The security light will come on.
3. Wait 10 minutes until the security light turns off.
4. Turn the ignition off.
5. Repeat Steps 2–4 two more times. After the third time, turn the ignition on; the
key is learned and all previously known
keys will no longer work with the
vehicle.
6. To learn the second key, turn the ignition off. Insert the second key to be
learned and turn the ignition on.
After two keys are learned, the remaining
keys can be learned by following the
procedure in “Programming with Two
Recognized Keys.”
If it becomes difficult to turn a key, inspect
the key blade for debris. Periodically clean
with a brush or pick. See your dealer if a replacement key or
additional key is needed.

Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle after acrash if I am wearing a seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your chance
of being conscious during and after a
crash, so you canunbuckle and get out,
is much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems only.
They work withseat belts —not instead
of them. Whether or not an airbag is
provided, all occupants still have to
buckle up to get the most protection.
Also, in nearly all states and in all
Canadian provinces, the law requires
wearing seat belts.
Buckle To Drive
If equipped, this feature prevents the vehicle
from being shifted out of P (Park) when
Teen Driver is active, and the driver seat
belt is not buckled. See Teen Driver0151.
If the engine is running, the driver seat belt
is not buckled, and the brake pedal is
pressed with the vehicle in P (Park), a
message displays in the Driver Information Center (DIC). Buckle the driver seat belt to
shift out of P (Park). Shifting from P (Park)
will be prevented once for each ignition
cycle.
For some fleet vehicles, shifting from
P (Park) will be prevented each time the
above conditions exist whether Teen Driver
is ON or OFF.
On some models, Buckle to Drive may also
prevent shifting out of P (Park) if a front
passenger is unbuckled under similar
conditions. A message displays in the DIC.
Buckle the front passenger seat belt to shift
out of P (Park). This feature may not allow
the vehicle to shift out of P (Park) if an
object, such as a briefcase, handbag, grocery
bag, laptop, or other electronic device, is on
the front passenger seat. If this happens,
remove the object from the seat or buckle
the seat belt to shift out of P (Park).
If the driver, or on some vehicles, the
present front passenger, remains unbuckled,
the DIC message will turn off after several
seconds and the vehicle can be shifted out
of P (Park). See
“Seat Belts”and“Child
Restraints” in the Index for information
about the importance of proper
restraint use. If the driver seat belt, and in some vehicles
the front passenger seat belt, are unbuckled
when driving, the seat belt reminder chime
and/or light(s) will come on. See
Seat Belt
Reminders 084.
This feature may not function properly if
the airbag readiness light is on. See Airbag
Readiness Light 085.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
in the vehicle, see Older Children044 or
Infants and Young Children 045. Review
and follow the rules for children in addition
to the following rules.
It is very important for all occupants to
buckle up. Statistics show that unbelted
people are hurt more often in crashes than
those who are wearing seat belts.
