Using the key bit, move the slot into the desired position.
WARNING
When the child safety lock is engaged, that rear door cannot be opened from the inside.
Never leave children, disabled persons, or anyone who cannot help themselves, in the vehicle when locking the doors. This could result in people being
trapped in the vehicle in an emergency. Depending on the time of year, people trapped in the vehicle can be exposed to very high or very low
temperatures.
A closed vehicle can become very hot or very cold, depending on the season. Particularly in the summer, heat buildup in the passenger and luggage
compartment of a parked vehicle can result in temperatures in the vehicle that are much higher than the outside temperatures. Temperatures can quickly
reach levels that can cause unconsciousness and death, particularly to small children.
Manually unlocking and locking the driver door

Read and follow the introductory information and safety information first ⇒ Introduction to the subjectꢀ
When locking the vehicle manually, all doors are locked. To unlock the vehicle manually, turn (counterclockwise) to the unlocking position. When the vehicle is
unlocked manually, only the driver door is unlocked. Note the instructions for the anti-theft alarm system ⇒ Anti-theft alarm systemꢀ.
Unfold the key bit from the remote control vehicle key ⇒ Vehicle key setꢀ.
If the vehicle has a concealed lock cylinder, insert the key bit from below into the opening of the cover cap on the driver door ⇒ Fig. 65ꢀ (arrow) and lift the
cover cap off. Grasping the door handle and pulling slightly makes it easier to remove the cap.
Insert the key bit into the lock cylinder of the driver door and unlock or lock the door. If the larger side of the vehicle key touches the door handle during
locking or unlocking, either pull the door handle slightly or reinsert the vehicle key in the lock cylinder with the opposite side facing up.
Reinsert the cover cap from top to bottom and press until it clicks into place. Grasping the door handle and pulling slightly makes it easier to reinstall the cap.
Special considerations when unlocking
If the vehicle is equipped with an anti-theft alarm system, the system remains activated for the unlocked vehicle. But the alarm is not triggered at first ⇒ Anti-
theft alarm systemꢀ.
Open the driver door. The alarm will sound.
Switch on the ignition. The electronic immobilizer recognizes a valid remote control vehicle key when the ignition is switched on and deactivates the anti-theft
alarm system.
The driver door can be unlocked separately from the inside the vehicle by pulling the door handle to open the door ⇒ Power locking systemꢀ.
The anti-theft alarm system, when installed, is not activated when the vehicle is locked manually with the key bit ⇒ Anti-theft alarm systemꢀ.
