Locks and security
2. Press 1/2 control within five
seconds of step 1.
3. Enter your personal 5 digit code.
Enter each digit within five seconds
of previous one.
Do not set a code that includes five
of the same number or presents
them in sequential order. Thieves
can easily figure out these types of codes.
Your personal code does not replace the permanent code that the
dealership gave you. You can use either code to unlock your vehicle. If a
second personal code is entered, the module will erase it in favor of the
new code.
If you wish to erase your personal code, use the following instructions:
1. Enter factory set code.
2. Press 1/2 control within five
seconds of step 1 and release.
3. Within five seconds of step 2,
press and hold the 1/2 control for
two seconds.
The system will now only respond
to the factory set code.
Unlocking the doors with the keyless entry system
To unlock the driver's door, enter either the factory-set code or personal
code (each digit pressed within five seconds of the prior digit). The
interior lamps will illuminate.
To unlock all doors, enter the
factory-set code or personal code
(driver door unlocks) and press the
3/4 control within five seconds.
