10 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

A WORD ABOUT YOUR KEYS
The double sided keys may be inserted into the locks
with either side up. The keys for your new vehicle are
enclosed in a plastic bag with a bar code label affixed to
the front. The bar code can be used to order duplicate
keys from your dealer or a locksmith. If you received
your keys without the bag, ask your dealer to give you
the number.
Key-In-Ignition Reminder
If you open the driver’s door when the key is in the
ignition switch, a chime will sound to remind you to
remove the key.
CAUTION!
An unlocked vehicle is an invitation to thieves.
Always remove the key from the ignition and lock
all the doors when leaving the vehicle unattended.
SENTRY KEY — IF EQUIPPED
With this system, an electronically coded ignition key
sends a signal to the vehicle electronics. If the electronics
recognizes the signal, the vehicle will start and continue
to run. If the system does not recognize the signal the
vehicle will start and run for a maximum of 2 seconds
after the initial key ON. After six unsuccessful attempts
at starting, the system will shut down until the correct
key is used.
NOTE:The Sentry Key Immobilizer System is not
compatible with remote starting systems. Use of these
systems may result in vehicle starting problems and a
loss of security protection. Additional Sentry Keys or
Mobil Speed-pass™ devices held against or immediately
adjacent to the ignition key when starting the engine may
cause vehicle starting problems. If a problem occurs,
remove the Sentry Key from the key-ring and attempt to
start the vehicle again. Pagers, cell phones, walkman, etc.
will have no effect on this system.
