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.

BabySmart
TM airbag deactivation system
Special BabySmart
TM compatible child seats, designed 
for use with the Mercedes-Benz system and available at 
any authorized Mercedes-Benz Center are required for 
use with the BabySmart
TM airbag deactivation system.
With the special child seat properly installed, the 
passenger side front airbag will not deploy. The 7 
indicator lamp located in the dashboard will be 
illuminated, except with key removed or in steering lock 
position 0. The system does not deactivate the door 
mounted side impact airbag.Self-test BabySmart
TM
without special child seat installed
After turning key in steering lock to position 1 or 2, the 
7 indicator lamp located in the dashboard comes on 
for approx. 6 seconds and then extinguishes.
If the indicator lamp should not come on or is 
continuously lit, the system is not functioning. You must 
see an authorized Mercedes-Benz Center before seating 
any child on the front passenger seat.BabySmart
TM is a trademark of Siemens Automotive Corp.
Wa r n i n g !
The BabySmart
TM airbag deactivation system will 
ONLY work with a special child seat designed to 
operate with it. It will not work with child seats 
which are not BabySmart
TM compatible.
Never place anything between seat cushion and 
child seat (e.g. pillow), since it reduces the 
effectiveness of the deactivation system.Follow the manufacturer’s instructions for 
installation of special child seats.The passenger front airbag will not deploy only if 
the 7 indicator lamp remains illuminated.
Please be sure to check the indicator every time 
you use the special system child seat.
Should the light go out while the restraint is 
installed, please check installation. If the light 
remains out, do not use the BabySmart
TM restraint 
to transport children on the front passenger seat 
until the system has been repaired.

Notes:
A warning sounds when the driver’s door is opened 
while the key is in steering lock position 1 or 0.
With the engine at idle speed, the charging rate of the 
alternator (output) is limited.
It is therefore recommended that you turn off 
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of 
the battery.
Unnecessary strain on the battery and charging system 
may be minimized by turning off the following power 
consumers, for example: Heated seats, rear window 
defroster.Caution!
To prevent accelerated battery discharge and a possible 
dead battery, always remove the key from the steering 
lock. Do not leave the key in steering lock position 0.
