Cadillac cts User Manual

If your vehicle has an automatic transmission, your
vehicle is programmed so that when the doors are
closed, the ignition is on and the shift lever is moved out
of PARK (P), all the doors will lock. The doors will
unlock every time you stop the vehicle and move the
shift lever back into PARK (P).

If your vehicle has a manual transmission, the doors 
will lock automatically after the vehicle speed reaches
5 mph (8 km). The doors will not automatically unlock
until the ignition is turned off and the key is removed
from the ignition switch.

If someone needs to exit the vehicle once the doors have
locked, have that person use the manual lever or power
door lock switch. When the door is closed again, it will
not lock automatically. Use the manual lever or power
lock switch to lock the door.

The power door locks can be programmed through
prompts displayed on the Driver Information Center
(DIC). These prompts allow you to choose various 
lock and unlock settings. For more information on
programming, see “Vehicle Programming and
Personalization Features” in the Index.

Your vehicle is equipped with rear door security locks
that prevent passengers from opening the rear doors on
your vehicle from the inside.

The rear door security locks
are located on the inside
edge of each rear door. You
must open the rear doors to
access them.

To use these locks, do the following:

1. Insert your key into the slot next to the rear door

security lock label and turn it to engage the lock.

2. Close the door.

3. Repeat the steps for the other rear door.

The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.
