Central locking system

Vehicle keys Included with your vehicle are 2 electronic main keys with integrated radio frequency and infrared remote controls plus removable mechanical key. The locking tabs for the mechanical key portion of the two electronic main keys are a different color to help distinguish it.

Warning! When leaving the vehicle always remove the electronic key from the starter switch, and lock your vehicle. Do not leave children unattended in the vehicle, or with access to an unlocked vehicle. Unsupervised use of vehicle equipment may cause serious personal injury.

Electronic main key

P80.35-2031-26

The electronic main key has an integrated radio frequency and infrared remote control, plus removable mechanical key. The remote control (1) operates all locks on the vehicle. The mechanical key (2) works only in the driver’s door, trunk, and storage compartment locks.

When using the mechanical key (2) for lock operations, it can be removed by sliding it out of the remote control. To do so, move locking tab (3) to the right and slide the mechanical key (2) in direction of arrow (4). The remote control transmitter is located in the electronic main key. The infrared receivers are located in the front door handles.

Note: Remove the mechanical key from the electronic main key when using valet parking service. To prevent access to trunk or storage compartments lock them separately and retain the mechanical key. See page 35 for separate locking of trunk and page 194 for locking of glove box.

Obtaining replacement keys Your vehicle is equipped with a theft deterrent locking system requiring a special key manufacturing process. For security reasons, replacement keys can only be obtained from your authorized Mercedes-Benz Center.

Important! Removing the electronic key from the starter switch activates the start lock-out. The engine cannot be started. Inserting the electronic key in the starter switch deactivates the start lock-out.

Note: In case the engine cannot be started (vehicle’s battery is in order), the system is not operational. Contact an authorized Mercedes-Benz Center or call 1-800-FOR- MERCedes (in the USA), or 1-800-387-0100 (in Canada).

General notes on the central locking system • If the electronic key is inserted in the starter switch,

the vehicle cannot be locked or unlocked with the remote control.

If the vehicle cannot be locked or unlocked: • Aim transmitter eye at a receiver of either front door

handle. Check the batteries of the electronic main key, see page 332, or synchronize the electronic main key, see page 334.

• Use the mechanical key to unlock the vehicle. To

start engine, insert the electronic key in the starter switch. There could be a slight delay until the electronic key can be turned in the starter switch.

Important! When unlocking the driver’s door with the mechanical key, the exterior lamps will flash and the alarm will sound. To cancel the alarm, insert the electronic key in the starter switch or press button Œ or ‹ on the electronic main key.

Central locking system

Radio frequency and infrared remote control The electronic main key has an integrated radio frequency and infrared remote control. Due to the extended operational range of the remote control, it could be possible to unintentionally lock or unlock the vehicle by pressing the transmit button. If one of the transmit buttons is pressed, the battery check lamp lights up briefly – indicating that the batteries are in order. See page 332 for checking batteries. The vehicle doors, trunk and fuel filler flap can be centrally locked and unlocked via remote control. Opening and closing the windows and sliding/pop-up roof can only be done with the infrared portion of the remote control. Aim transmitter eye at a receiver (6 or 7), press and hold transmit button Œ or ‹, see page 29. With vehicle centrally locked, the trunk can also be opened by using the remote control. If the electronic key is inserted in starter switch, the vehicle cannot be locked or unlocked, and the trunk lid cannot be opened with the remote control.

Antitheft alarm system

1 Indicator lamp in switch located in center console The antitheft alarm is automatically armed or disarmed with the remote control by locking or unlocking the vehicle. The antitheft alarm is armed within approximately 10 seconds after locking the vehicle. A blinking lamp (1) indicates that the alarm is armed.

Operation: Once the alarm system has been armed, the exterior vehicle lamps will flash and an alarm will sound when someone: • opens a door, • opens the trunk, • opens the hood, • attempts to raise the vehicle.

The alarm will last approximately 3 minutes in form of flashing exterior lamps. At the same time an alarm will sound for 30 seconds. The alarm will stay on even if the activating element (a door, for example) is immediately closed. If the alarm stays on for more than 20 seconds, an emergency call is initiated automatically.

Front seat adjustment

Warning! Do not adjust the driver’s seat while driving. Adjusting the seat while driving could cause the driver to lose control of the vehicle. Never ride in a moving vehicle with the seat back reclined. Sitting in an excessively reclined position can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the belt would apply force at the abdomen or neck. That could cause serious or fatal injuries. The seat back and seat belts provide the best restraint when the wearer is in an upright position and belts are properly positioned on the body. Never place hands under seat or near any moving parts while a seat is being adjusted.
