{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 unintentionallymoving 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 that is part of the Remote
Keyless Entry (RKE) transmitter can be used
for the ignition and all locks.
