{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(Continued)

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.
If the vehicle is equipped with a
keyed ignition, 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 RKE
transmitter can be used for the
ignition and all locks if the vehicle is
a key access vehicle. If the vehicle
has the keyless ignition, the key can
be used for the locks.
