Antitheft alarm system
1Indicator 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 keys 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,
• opens the storage compartment between the front 
seats,
• 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, for 
example, an opened door is immediately closed again. If 
the alarm stays on for more than 20 seconds, an 
emergency call is initiated automatically. See Tele Aid 
on page 156.
The antitheft alarm system is switched off automatically 
if the vehicle is unlocked with the electronic main key.

Power seats
The switches are located in both doors.
Turn key in steering lock to position 1 or 2 (with either 
door open, the power seats can also be operated with the 
key removed or in steering lock position 0).
The position should be as far rearward as possible, 
consistent with ability to properly operate controls.We recommend to adjust the power seat in the following 
order:
1Seat, up/down
Press the switch (up/down direction) until 
comfortable seating position with still sufficient 
headroom is reached.
2Seat adjustment, fore/aft
Press the switch (fore/aft direction) until a 
comfortable seating position is reached that still 
allows you to reach the accelerator/brake pedal 
safely.
3Seat cushion tilt
Press the switch in the direction of the arrow until 
your legs are lightly supported.
4Backrest tilt
Press the switch in the direction of the arrow until 
the backrest is in an almost upright position. Adjust 
the steering wheel until your arms are slightly 
angled when holding the steering wheel. For 
steering wheel adjustment see page 70.

(with shoulder belt height adjustment)
Adjust the head restraint so that the upper portion 
of the shoulder belt is located as close as possible to 
the middle of the shoulder. The head restraint can 
be tilted forward by hand.
Note:
To prevent the backrest from touching the soft top 
storage compartment cover when the seat is moved 
back, the backrest will automatically move to a more 
upright position.
When reclining the backrest, the seat will automatically 
move forward to prevent the backrest from touching the 
soft top storage compartment cover.
Wa r n i n g !
When leaving the vehicle always remove the key 
from the steering lock, and lock the vehicle.The power seats can also be operated with a door 
open. 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.
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 backrest 
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 even fatal injuries. The backrest and seat 
belt provide the best restraint when the wearer is 
in an upright position and the belt is properly 
positioned on the body.The rear storage area should never be occupied by 
passengers since the vehicle is a 2 seater. 
Furthermore, there is a risk of injury in the rear by 
adjusting the power assisted front seats.Never place hands under seat or near any moving 
parts while a seat is being adjusted.

Storing position in memory
6Memory button
7Position buttons “1”, “2” and “3”
After the seat and head restraint are positioned, push 
memory button (6), release, and within 3 seconds push 
position button  “1”. Two additional sets of positions 
may be stored into memory using position buttons “2” 
and “3”.Using the same position button, the steering wheel 
position and exterior rear view mirror positions will 
also be stored together with the seat position. For 
adjusting steering wheel and mirrors see page 70.
Recalling stored positions
Press position button “1”, “2” or “3” and hold until seat/
head restraint/steering wheel/exterior rear view mirror 
movement has stopped.

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.
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.

Wa r n i n g
The seat belts provide protection only with the 
backrest locked in place and, therefore, it must be 
locked in place with the vehicle in motion. Do not 
drive the vehicle when the backrest is not locked in 
place.
