Automatic central locking
The central locking switch also operates the automatic 
central locking.
Wit h th e automa tic central locking system activated, t he 
doors and trunk are locked at vehicle speeds of approx. 
9 mph (15 km/h) or more. The fuel filler f lap remains 
unlocked.
To  a ctiva te:
With key in steering lock position 2 hold upper portion 
of switch (1) for a minimum of 5 seconds.
To  dea cti vate :
With key in steering lock position 2 hold lower portion 
of switch (2) for a minimum of 5 seconds.
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.If a door is opened 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.
Important!
When towing the vehicle, or with the vehicle on a 
dynamometer test stand, please, note the following:
With the automatic central locking activated and the 
key in steering lock position 2, the vehicle doors will 
lock if the left front wheel as well as the right rear 
wheel spin are turning at vehicle speeds of approx. 
9 mph (15 km/h) or more.
To prevent the vehicle door locks from locking, 
deactivate the automatic central locking.
Emergency unlocking in case of accident
The doors unlock automatically a short time after a 
strong deceleration is detected, such as in a collision 
(this is intended to aid rescue and exit). Driving on 
rough roads may cause the vehicle to unlock. If 
necessary, the vehicle can be locked again with the 
interior central locking switch.

Prior to operating the vehicle, the driver should adjust 
the seat height for proper vision as well as fore/aft 
placement and backrest angle to insure adequate 
control, reach, operation, and comfort. The head 
restraint should also be adjusted for proper height. 
Adjust head restraint to support the back of the head 
approximately at ear level. See also airbag section for 
proper seat positioning on page 60.
In addition, also adjust the steering wheel to ensure 
adequate control, reach, operation, and comfort.
Both the inside and outside rear view mirrors should be 
adjusted for adequate rearward vision.
Fasten seat belts. Infants and small children should be 
seated in a properly secured restraint system that 
complies with U.S. Federal Motor Vehicle Safety 
Standard 213 and Canadian Motor Vehicle Safety 
Standard 213.
All seat, head restraint, rear view mirror, and steering 
wheel adjustments as well as fastening of seat belts 
should be done before the vehicle is put into motion.
BabySmart
TM is a trademark of Siemens Automotive Corp.
Wa r n i n g !
Children 12 years old and under must never ride in 
this vehicle, except in a Mercedes-Benz authorized 
BabySmart
TM compatible child seat, which operates 
with the BabySmart
TM 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.Infants and small children must be seated in an 
appropriate infant or child restraint system, which 
is properly secured with the vehicle’s seat belt, 
fully in accordance with the child seat 
manufacturer’s instructions.A child’s risk of serious or fatal injuries is 
significantly increased if the child restraints are 
not properly secured in the vehicle and the child is 
not properly secured in the child restraint.
