your vehicle’s engine and the theft indicator light will flash on and off
rapidly. If failure repeats, bring your vehicle to your dealer to have the
new key(s) programmed.
To program additional new unprogrammed key(s), repeat this procedure
from Step 1 for each additional key.
ACTIVE ANTI-THEFT SYSTEM (IF EQUIPPED)
The active anti-theft system is designed to warn you in the event of an
unauthorized entry to your vehicle and is also designed to help prevent
the unwanted towing of the vehicle.
When the vehicle is locked and armed, the active anti-theft system
monitors the following:
•Doors
•Hood
•Trunk
•Movement inside the vehicle
•Change in vehicle inclination
Note:The active anti-theft system includes a motion detection system
which monitors the passenger cabin and a vehicle incline sensor which
detects changes in vehicle attitude.
The interior motion detection and vehicle incline sensing systems
will operate only when the vehicle is locked using the remote
keyless entry transmitter or when using the power door lock
control with the accompanying door open and all doors then
become closed. For convertible vehicles, the convertible top must
be in the fully closed and latched position for the interior motion
sensing system to arm. If you lock the vehicle using the key in the
driver door key cylinder, the system will monitor the doors,
trunk, and hood but the motion sensing and vehicle incline
sensing will not arm.
Do not arm the interior motion detection system if movement within the
vehicle is likely to occur. Additionally, do not arm the vehicle incline
sensing system when the vehicle is in transport.
For proper operation of the interior motion detection system, ensure all
windows are closed prior to arming the system. This will help prevent
accidental alarm activation due to external influences and ensure proper
interior motion detection. Additionally, the interior motion sensing
system will not arm if either door is ajar

For maximum vehicle performance, keep the following information in
mind when adding accessories or equipment to your vehicle:
•When adding accessories, equipment, passengers and luggage to your
vehicle, do not exceed the total weight capacity of the vehicle or of
the front or rear axle (GVWR or GAWR as indicated on the Safety
Compliance Certification label). Consult your dealer for specific weight
information.
• The Federal Communications Commission (FCC) and Canadian Radio
Telecommunications Commission (CRTC) regulate the use of mobile
communications systems —such as two-way radios, telephones and
theft alarms - that are equipped with radio transmitters. Any such
equipment installed in your vehicle should comply with FCC or CRTC
regulations and should be installed only by a qualified service
technician.
• Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use.
