cluster displayPractical hints Car care Index For safety reasons, the soft top cannot be unlocked
while driving.
However, if the soft top is not completely locked, it can
be locked while driving by pushing the soft/hardtop
switch forward.
If the indicator lamp in the soft top switch blinks while
activating the switch,
• the battery voltage may be insufficient - start engine
and let run while activating switch,
• the system may be overloaded (for example after
lowering or raising the soft top approx.
5 consecutive times) - after approx. 2 minutes the
soft top switch may be activated again,
• and the power supply was interrupted (battery
disconnected or empty), the soft top cannot be fully
raised or lowered.
To raise the soft top, for safety reasons, first remove key
from steering lock. Lower soft top by hand into
compartment, and resynchronize the power windows.
See page 116.
To lower the soft top, first resynchronize the power
windows. See page 116.If t he indicator la mp continues to bl ink, l ock th e sof t top
manually. See page 253.
Have the system checked at your authorized Mercedes-
Benz Center as soon as possible.
Note:
If the roll bar was raised automatically, the process of
raising or lowering the soft top will take somewhat
longer, as the roll bar must first be lowered.
Whenever possible, park vehicle in the shade as
continuous exposure to sun rays can prematurely
deteriorate the soft top material.
Permanent creases in the plastic window, caused by
storage of the soft top in the storage compartment,
cannot be avoided.
The soft top may become moldy if it is kept in the
storage compartment for an extended period.
Therefore, we recommend raising and airing it
thoroughly with the side windows open (do not expose
it to the sun) at regular intervals during the wet and
cold seasons.

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.

Park position
The park position is to be used when parking the
vehicle. Engage only with the vehicle stopped.
The park position is not intended to serve as a
brake when the vehicle is parked. Rather, the
driver should always use the parking brake in
addition to placing the selector lever in park to
secure the vehicle.
Note:
The key can be removed from the steering lock
only with the foot off the brake pedal and the
selector lever in position “P”. With the key
removed, the selector lever is locked in
position “P”.
Reverse gear
Shift to reverse gear only with the vehicle
sto pp ed.
Depending on the program mode selector switch
position “S” or “W” the maximum speed in the
reverse gear is different. However, it is not
possible to change the program mode while in
reverse.Neutral
No power is transmitted from the engine to the
drive axle. When the brakes are released, the
vehicle can be moved freely (pushed or towed). Do
not engage “N” while driving except to coast
when the vehicle is in danger of skidding (e.g. on
icy roads, see page 182).
Important!
Coasting the vehicle, or driving for any other
reason with selector lever in “N” can result in
transmission damage that is not covered by the
Mercedes-Benz Limited Warranty.
The transmission automatically upshifts through
5th gear. Position “D” provides optimum driving
characteristics under all normal operating
conditions.
Upshift through 4th gear only. Suitable for
performance driving. To shift from position “D”
to “4”, push selector lever to the left.
Upshift through 3rd gear only. Suitable for
moderately steep hills. Since the transmission
does not shift higher than 3rd gear, this gear
selection will allow use of the engine’s braking
power downhill.

BrakesThe condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on, the brake f luid
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake f luid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.
Al l checks and service work on the brake system shoul d
be carried out by an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid recommended by
Mercedes-Benz.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components, the first braking action
may be somewhat reduced and increased pedal
pressure may be necessary to obtain expected
braking effect. Be sure to maintain a safe distance
from vehicles in front.Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.It can also result in the brakes overheating thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.
Wa r n i n g !
If other than recommended brake pads are
installed, or other than recommended brake fluid
is used, t he braking properties of th e vehic le can be
degraded to an extent that safe braking is
substantially impaired. This could result in an
accident.The trunk is the preferred place to carry objects.

Caution!
When driving down long and steep grades, relieve the
load on the brakes by shifting into a lower gear to use
the engine’s braking power. This helps prevent
overheating of the brakes and reduces brake pad wear.
After hard braking, it is advisable to drive on for some
time, rather than immediately parking, so the air stream
will cool down the brakes faster.
Driving off
Apply the service brakes to test them briefly after
driving off. Perform this procedure only when the road
is clear of other traffic.
Warm up the engine smoothly. Do not place full load on
the engine until the operating temperature has been
reached.
W hen sta rting of f on a sl ippery surfa ce, d o not al low one
drive wheel to spin for an extended period with the ESP
switched off. Doing so may cause serious damage to the
drive train which is not covered by the Mercedes-Benz
Limited Warranty.Parking
Important!
Always engage the parking brake whenever parking or
leaving the vehicle. In addition, move selector lever to
position “P”.
When parking on hills, always set the parking brake.
Wa r n i n g !
To reduce the risk of personal injury as a result of
vehicle movement, before
turning off the engine
and leaving the vehicle always:
1. Keep right foot on the service brake pedal.
2. Firmly engage parking brake.
3. Move the selector lever to position “P”
4. Slowly release the service brake pedal.
5. Turn front wheels towards the road curb.
6. Turn the key to steering lock position 0 and
remove.
7. Take the key and lock vehicle when leaving.

Antilock brake system (ABS)
Important!
The ABS improves steering control of the vehicle during
hard braking maneuvers.
The ABS prevents the wheels from locking up above a
vehicle speed of approximately 5 mph (8 km/h)
independent of road surface conditions.At the instant one of the wheels is about to lock up, a
slight pulsation can be felt in the brake pedal,
indicating that the ABS is in the regulating mode. Keep
firm and steady pressure on the brake pedal while
experiencing the pulsation.
Continuous steady brake pedal pressure results in
applying the advantages of the ABS, namely braking
power and ability to steer the vehicle.
In the case of an emergency brake maneuver keep
continuous full pressure on the brake pedal. In this
manner only can the ABS be most effective.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the
increased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and functions as a reminder to take extra
care while driving.
Wa r n i n g !
Do not pump the brake pedal, rather use firm,
steady brake pedal pressure. Pumping the brake
pedal defeats the purpose for ABS and significantly
reduces braking effectiveness.

cluster displayPractical hints Car care Index Notes:
The malfunction indicator lamp for the ESP is combined
with that of the BAS.
The yellow BAS/ESP malfunction indicator lamp in the
instrument cluster and the yellow ESP warning
lampv in the speedometer dial come on with the
key in steering lock position 2. They should go out with
the engine running.
If the BAS/ESP malfunction indicator lamp comes on
permanently with the engine running, a malfunction
has been detected in either system. Pressing the
a ccelera tor peda l will require greater e ffort. Only partia l
engine output will be available.
If the BAS malfunctions, the brake system functions in
the usual manner, but without BAS.
If the BAS/ESP malfunction indicator lamp come s on,
have the BAS or ESP checked at your authorized
Mercedes-Benz Center as soon as possible.
With the ABS malfunctioning, the ESP is also switched
off.Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lamp in speedometer
dial comes on). For this reason, all wheels, including the
spare wheel, must have the same tire outside diameter.
When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and/or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the BAS/ESP malfunction
indicator lamp may be illuminated with the engine
running.
Turn steering wheel completely to the left and then to
the right. The BAS/ESP malfunction indicator lamp
should go out.

Depending upon road surface conditions, load, driving
style, ADS will automatically adjust the optimal ride
firmness.
The malfunction indicator lamp comes on with the key
in steering lock position 2 and should go out with the
engine running.
If the malfunction indicator lamp stays on after the
engine is running or comes on while driving, then the
system has detected a malfunction.
Have the ADS checked at your authorized
Mercedes-Benz Center as soon as possible.
Note:
If the power supply was interrupted (battery
disconnected or empty), the malfunction indicator lamp
will light up when the engine is running.

cluster displayPractical hints Car care Index Charge indicator lamp
Should the charge indicator lamp fail to
come on prior to starting when the key is in
steering l ock position 2 or sh ou ld it fa il to go
out after starting or during operation, this indicates a
malfunction which must be repaired immediately at an
authorized Mercedes-Benz Center.
If th e ch arge indica tor l amp com es on, or a loss of power
steering assistance is noticeable while the engine is
running, this may indicate that one of the two poly-V-
belts has broken. Should this condition occur, the poly-
V-belt mu st be repl aced before continuing to operate t he
vehicle. Otherwise, the engine may overheat due to an
inoperative water pump which may result in damage to
the engine.
Do not continue to drive the vehicle with the charge
indicator lamp illuminated. Doing so could result in
serious engine damage that is not covered by the
Mercedes-Benz Limited Warranty.Exterior lamp failure indicator lamp
With the key in steering lock position 2, an
indicator lamp comes on. It should go out
when the engine is running.
If the warning lamp does not go out after starting the
engine, or if it comes on while driving, this lamp
indicates a failure in the parking lamp, taillamp, stop
lamp, or low beam headlamp.
If a n exterior lamp fa ils, the indica tor lamp will com e on
only when that lamp is switched on.
If a brake lamp fails, the lamp failure indicator will
come on when applying the brake and stays on until the
engine is turned off.
Note:
If additional lighting equipment is installed (e.g.
auxiliary headlamps etc.) be certain to connect into the
fuse before the failure indicator monitoring unit in
order to avoid damaging the system.
