(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.

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.

lumbar and side support.
The seat cushion movement and amount of backrest 
cushion height and curvature can be continuously 
varied with regulators (1, 2 and 3) after turning the key 
in steering lock to position 2.
The side bolsters of the backrest can be adjusted with 
rocker switch (4):
• press down forward end - 
increase side support,
• press down rearward end -
decrease side support.
If the engine is turned off, the last cushion setting is 
retained in memory, and automatically adjusts the 
cushion to this setting when the engine is restarted.

143 Soft top
Te ch n ica l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Soft top
A minimum height clearance of 6.5 ft (2 m) is required 
to lower or raise the soft top.
Do not lower a frozen soft top until thawed and dry. 
Doing so may result in damage not covered by the 
Mercedes-Benz Limited Warranty.
To prevent m ildew, t he soft top must be dry before 
lowering it into the storage compartment.
The soft top should not be lowered or raised at outside 
temperatures below +5°F (-15°C), since the material 
becomes less pliable with lower temperatures.
The lowering or raising procedure is immediately 
interrupted by releasing the soft top switch.
Wa r n i n g !
Before operating the soft top switch make sure that 
no persons due to inattention are injured by the 
moving parts (roll bar, soft top frame and soft top 
lid).Hands must never be placed near the roll bar, soft 
top frame, upper windshield area or soft top storage 
compartment while the soft top is being locked or 
unlocked. Serious personal injury may occur.

Lower hood and let it drop into lock from a height of 
approx. 1 ft. (30 cm), assisting with hands placed flat on 
edges of hood (3).
To avoid hood damage, please make sure that hood is 
fully closed. If not, repeat closing procedure. Do not 
push down on hood to attempt to fully close it.
Wa r n i n g !
To help prevent personal injury, stay clear of 
moving parts when the hood is open and the engine 
is running. Be sure the hood is properly closed 
before driving. When closing hood, use extreme 
caution not to catch hands or fingers.The radiator fan may continue to run another 
approximate 30 seconds or even restart after the 
engine has been turned off. Stay clear from fan 
blades.
The engine is equipped with a transistorized 
ignition system. Because of the high voltage it is 
dangerous to touch any components (ignition coils, 
spark plug sockets, diagnostic socket) of the 
ignition system
• with the engine running,
• while starting the engine,
• if ignition is “on” and the engine is turned 
manually.If you see flames, steam or smoke coming from the 
engine compartment, or if the coolant temperature 
gauge indicates that the engine is overheated, do 
not open the hood. Move away from vehicle and do 
not open the hood until the engine has cooled. If 
necessary, call a fire department.
