{Warning
Leaving children in a vehicle with the
ignition key is dangerous and children or
others could be seriously injured or killed.
They could operate the power windows
or other controls or make the vehicle
move. The windows will function with
the keys in the ignition, and children or
others could be caught in the path of a
closing window. Do not leave children in
a vehicle with the ignition key.

{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
locks.
See your dealer if a replacement key or
additional key is needed.
If it becomes difficult to turn a key, inspect
the key blade for debris. Periodically clean
with a brush or pick.
If locked out of the vehicle, see
Roadside
Assistance Program 0268.

Programming Transmitters to the Vehicle
Only RKE transmitters programmed to the
vehicle will work. If a transmitter is lost or
stolen, a replacement can be purchased and
programmed through your dealer. When the
replacement transmitter is programmed to
the vehicle, all remaining transmitters must
also be programmed. Any lost or stolen
transmitters no longer work once the new
transmitter is programmed. Each vehicle can
have up to four transmitters programmed
to it.
Battery Replacement
{Warning
Never allow children to play with the RKE
transmitter. The transmitter contains a
small battery, which can be a choking
hazard. If swallowed, internal burns can
occur, resulting in severe injury or death.
Seek medical attention immediately if a
battery is swallowed.
{Warning
To avoid personal injury, do not touch
metal surfaces on the RKE transmitter
when it has been exposed to extreme
heat. These surfaces can be hot to the
touch at temperatures above 59 °C
(138 °F).
Caution
When replacing the battery, do not touch
any of the circuitry on the transmitter.
Static from your body could damage the
transmitter.
Caution
Always replace the battery with the
correct type. Replacing the battery with
an incorrect type could potentially create
a risk of battery explosion. Dispose of
used batteries according to instructions
and local laws. Do not attempt to burn,
crush, or cut the used battery, and avoid
exposing the battery to environments
with extremely low air pressures or high
temperatures.Replace the battery if the DIC displays
REPLACE BATTERY IN REMOTE KEY.
To replace the battery:
1. Separate the transmitter with a flat, thin object, such as a flat head screwdriver.
.Carefully insert the tool into the
notch located along the parting line
of the transmitter. Do not insert the
tool too far. Stop as soon as
resistance is felt.
.Twist the tool until the transmitter is
separated.
2. Remove the old battery. Do not use a metal object.
