Controls in detail Locking and unlocking Close trunk lid with hands placed flat on trunk lid. Warning! i To prevent an inadvertent lockout, do not place the SmartKey in the trunk. Vehicles with KEYLESS-GO*: To prevent a possible inadvertent lockout, the trunk lid will open automatically if a SmartKey with KEYLESS-GO is recognized inside the trunk. When the hardtop is retracted, it must be completely lowered in the trunk before the trunk lid can be closed ( page 236). Valet locking G i To deny any unauthorized person access to the trunk, e.g. when you valet park the vehicle, lock it separately with the mechanical key. Leave only the SmartKey or SmartKey with KEYLESS-GO* less its mechanical key with the vehicle. The lock is located next to the handle above the rear license plate recess. Only drive with the trunk closed. Among other dangers, such as blocked visibility, exhaust fumes may enter the vehicle interior. i If the vehicle was previously centrally locked, the trunk lid will lock automatically when closed ( page 109). The turn signals will flash three times to confirm locking. 110
