The central locking switch is located in the center console. The doors can only be locked with the central locking
switch, if the front doors are closed. If the car was previously locked with the remote control or mechanical key, the
doors and trunk cannot be unlocked with the central locking switch. If the vehicle was previously locked with the
central locking switch, while in the selective remote control mode, only the door opened from the inside is unlocked. If
the vehicle was previously locked with the central locking switch, while in the global remote control mode, the
complete vehicle is unlocked when a front door is opened from the inside.

Notes:
If doors are unlocked with the central locking switch after activating the automatic central locking, and neither door is
opened, then the doors remain unlocked even at vehicle speeds of approx. 9 mph (15 km/h) or more. Opening a door
from the inside at speeds of approx. 9 mph (15 km/h) or less with the automatic central locking activated, the door will
again be automatically locked at speeds of approx. 9 mph (15 km/h) or more.

Antitheft Alarm System

1. Indicator lamp in switch located in center console

The antitheft alarm is automatically armed or disarmed with the remote
control or any of your vehicle's mechanical keys by locking or unlocking the driver's door or the trunk.
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 the horn will sound
intermittently when someone:
• opens a door,
• opens the trunk,
• opens the hood,
• attempts to raise the vehicle.
The alarm will last approximately 21/2 minutes in the form of blinking 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.

Note:
We recommend that you carry the electronic reserve key with mechanical key with you and keep it in a safe place
(e.g. your wallet) so that it is always handy. Never leave the electronic reserve key in the vehicle.

Infant and Child Restraint Systems
We recommend that all infants and children be properly restrained at all times while the vehicle is in
motion. All lap-shoulder belts except driver seat have special seat belt retractors for secure fastening
of child restraints. To fasten a child restraint, use th is seat belt: Follow child restraint instructions for
routing. Then pull shoulder belt out completely and let it retract. During the seat belt retraction a
ratcheting sound can be heard to indicate that the spec ial seat belt retractor is activated. The belt is
now locked. Push down on child restraint to take up any slack. To deactivate, release seat belt
buckle and let seat belt retract completely. The seat belt can again be used in the usual manner.

Warning !
Never release the seat belt buckle while vehicle is in motion, since the special seat belt
retractor will be deactivated.

Important !
The use of infant or child restraints is required by law in all 50 states and all Canadian provinces.
Infants and small children should be seated in an approp riate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with U.S. Federal Motor Vehicle Safety Standard
213 and Canadian Motor Vehicle Safety Standard 213. A statement by the child restraint
manufacturer of compliance with this standard ca n be found on the instruction label on the restraint
and in the instruction manual provided with the re straint. When using any infant or child restraint
system, be sure to carefully read and follow all manu facturer's instructions for installation and use.
Please read and observe warning labels affixed to inside of vehicle.


Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz
authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system
installed in the vehicle to deactivate the passenger side front airbag when it is properly
installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this
happens, serious or fatal injury will result.
According to accident statistics, children are safer when properly restrained in the rear
seating positions than in the front seating positions. Infants and small children must ride in
back seats and be seated in an infant or child restraint system, which is properly secured
with the vehicle's seat belt, fully in accordan ce with the seat manufacturer's instructions.
Infants and small children should never share a seat belt with another occupant. During an
accident, they could be crushed between the occupant and seat belt. Children too big for
child restraint systems must ride in back seats using regular seat belts. Position shoulder
belt across chest and shoulder, not face or neck. A booster seat is necessary to achieve
proper belt positioning for children from 41 Ibs. to the point where a lap/shoulder belt fits
properly without one.
When the child restraint is not in use, remove it from the car or secure it with the seat belt to
prevent the child restraint from becoming a projectile in the event of an accident.

U.S.A. Models only:
Since 1986 all U.S. child restraints comply with U. S. regulations without the use of a tether strap.
Canada Models only: This vehicle is provided with tether anchorages for a top tether strap. Consult
your authorized Mercedes-Benz dealer for installa tion of these anchorages. In compliance with
Canadian Motor Vehicle Safety Standard 210.1, ch ild restraint tether anchorage hardware is
attached to the tool kit located in the trunk.

Split Folding Rear Seat Backrest

On vehicles with optional split folding rear seat backrest you can fold down the two sections
separately to enlarge the cargo area.

Fold down:
Pull locking handle and fold backrest forward.
Set up:
Pull backrest up until it locks in its upright position. Check for secure locking by pushing and pulling on the backrest.

Warning !
Always lock backrest in its upright position when rear seat bench is occupied by passengers, cargo is being
carried in the trunk, or the extended cargo area is not in use.


Note:
To prevent unauthorized persons from access to the trunk, always lock backrest in its upright position.

Loading instructions
(Vehicles with enlarged cargo area)

The total load weight including vehicle occupants and luggage/ cargo should not exceed the vehicle capacity
weight indicated on the certification tag which can be found on the left door pillar. The handling characteristics
of a fully loaded vehicle depend greatly on the load distribution. It is therefore recommended to load the vehicle
according to the illustrations shown, with the heaviest items being placed towards the front of the vehicle.
Always place items being carried against front or rear seat backrests, and fasten them as securely as possible.
The heaviest portion of the cargo should always be kept as low as possible since it influences the handling
characteristics of the vehicle.

Notes:
The trunk is the preferred place to carry objects. The enlarged cargo area should only be used for items which
do not fit in the trunk alone.

Warning !
In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the
vehicle, and can cause injury to vehicle occupants unless the items are securely fastened in the vehicle.
To help avoid personal injury during a collision or sudden maneuver, exercise care when stowing things.
Put luggage or cargo in the trunk if possible. Do not pile luggage or cargo higher than the seat backs.
Do not place anything on the shelf below the rear window. Never drive vehicle with trunk lid open while
pass-through is not closed and seat backrest sections not locked in its upright position. Deadly carbon
monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death.

open, the screen will also retract.


Warning !
When closing the sliding/ pop-up roof, be sure that there
is no clanger of anyone being harmed by the closing
procedure. The closing procedure can be immediately
reversed by either moving the switch in direction
(1) or (3), turning the mechanical key to the unlocking
position, or pressing button on the remote control,
and holding it.
Notes:
The sliding/pop-up roof can be opened or closed manually should an electrical malfunction occur,
refer to Sliding/Pop-Up Roof, Emergency Operation in Index. The sliding/pop-up roof can also be

(see Central Locking System in Index).


Synchronizing Sliding/Pop-Up Roof
If the power supply was interrupted (battery disconnected or empty), or if the sliding/pop-up roof is
blocked during closing/opening procedure, the system has to be synchronized. To do so, turn electronic
key in steering lock to position 2, move and hold switch in direction (3) until the sliding/pop-up roof is
completely raised at rear, and hold for additional 1 second.
