At speeds between approximately 35 mph (60 km/h)
and 60 mph (95 km/h) the vehicle chassis is lowered to
its normal level.
At speeds above approximately 60 mph (95 km/h) the
vehicle chassis is lowered an additional one half inch
(15 mm).
Notes:
When exceeding approximately 35 mph (60 km/h), the
system will switch from option 2 to option 1. Only one
indicator lamp will be illuminated.
When exceeding approximately 60 mph (95 km/h) the
system will switch from option 1 to Normal Level. The
indicator lamp will go out.
If speed exce eds approx. 35 mph (60 km/h) bu t d oes not
exceed 60 mph (95 km/h), the system will switch from
option 2 to option 1 when vehicle speeds drop below
approximately 35 mph (60 km/h).
If speed does not exceed 35 mph (60 km/h), the system
will switch from option 2 to option 1 when driving on
after the vehicle has been stopped.Wheel change switch (2)
Prior to changing a wheel, depress wheel change switch
with engine running. The indicator lamp in the switch
and ADS malfunction indicator lamp light up. The
presently selected level option cannot be changed now.
After activating the wheel change switch turn off the
engine.
Wa r n i n g !
Do not drive the vehicle while the wheel change
switch is activated since the vehicle suspension
will not function properly.

(SL 600 only)
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.
Turn the steering wheel from full left to full right lock
position. The light should go out. Adaptive damping system adjustment

Malfunction and indicator lamps
in the instrument cluster
General information:
If a bulb in the instrument cluster fails to light up
during the bulb self-check when turning the electronic
key in steering lock to position 2, have it checked and
replaced if necessary.
On-board diagnostic system
Check engine malfunction indicator lamp
The Sequential Multiport Fuel Injection
(SFI) control module monitors emission
control components that either provide
input signals to or receive output signals from the
control module. Malfunctions resulting from
interruptions or failure of any of these components are
indicated by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster and are
simultaneously stored in the SFI control module.
If the “CHECK ENGINE” malfunction indicator lamp
comes on, have the system checked at your authorized
Mercedes-Benz Center as soon as possible.With some exceptions, the control module switches off
the “CHECK ENGINE” malfunction indicator lamp if the
condition, causing the lamp to come on, no longer exists
during three consecutive cycles.
An on-board diagnostic connector is located in the
passenger compartment near the engine hood release,
allowing the accurate identification of system
malfunctions through the readout of diagnostic trouble
codes.
Brake warning lamp
Except Canada
Canada only
With the key in steering lock position 2, the brake
warning lamp will come on. It should go out when the
engine is running.

205 Malfunction and indicator lamps
Technical

and controlsOperation DrivingInstrument
cluster displayPractical hints Car care Index The brake warning lamp will come on:
• when there is insufficient brake fluid in the
reservoir (engine running and parking brake
released), or
• when the parking brake is set (engine running).
Note:
If you find that the minimum mark on the brake f luid
reservoir is reached, have the brake system checked for
brake pad thickness and leaks.Brake pad wear indicator lamp
With the key in steering lock position 2, the
brake pad wear indicator lamp comes on. It
goes out when the engine is running.
If the indicator lamp lights up during braking, this
indicates that the brake pads are worn down.
Have the brake system checked at your authorized
Mercedes-Benz Center as soon as possible.
Wa r n i n g !
Driving with the brake warning lamp illuminated
can result in an accident. Have your brake system
checked immediately if the brake warning lamp
stays on. Don‘t add brake fluid before checking the
brake system. Overfilling the brake fluid reservoir
can result in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You can be
seriously burned.

cluster displayPractical hints Car care Index Fuel reserve and fuel cap placement warning
With the key in steering lock position 2, the
fuel reserve warning lamp comes on. It
should go out immediately when the engine
is running.
If the warning lamp does not go out after starting the
engine, or if it comes on while driving, it indicates that
the fuel level is down to the reserve quantity of
approximately 2.6 gal (10 liters).
The warning lamp blinks when the fuel cap is not
closed, or a fuel system leak has been detected.
Retighten cap and see if warning lamp goes out after
restart and next OBD selfcheck.
If the warning lamp continues to blink after closing the
fuel cap correctly, have the fuel system checked at your
authorized Mercedes-Benz Center as soon as possible.
Leaving the engine running and the fuel cap open can
cause the “CHECK ENGINE” lamp to illuminate (see also
page 204).Electronic stability program (ESP) — warning lamp
The yellow ESP warning lamp in the
speedometer dial comes on with the key in
steering lock position 2. It should go out
with engine running.
See page 192 if the warning lamp lights up or flashes
when the vehicle is moving.
BAS-/ESP malfunction indicator lamp
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 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, see page 188
and 192.

cluster displayPractical hints Car care Index Low engine coolant level warning lamp
With the key in steering lock position 2, the
warning 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, then the coolant
level has dropped below the required level. If no leaks
are noticeable and the engine temperature does not
increase, continue to drive to the nearest service station
and have coolant added to the coolant system,
see page 224.
The low engine coolant level warning light should not be
ignored. Extended driving with the light illuminated
may cause serious engine damage not covered by the
Mercedes-Benz Limited Warranty.In cases of major or frequent minor coolant loss, have
the cooling system checked at your authorized
Mercedes-Benz Center as soon as possible.
Note:
Do not drive without coolant in the cooling system. The
engine will overheat causing major engine damage.
Monitor the coolant temperature gauge while driving.
Wa r n i n g !
Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which may
burn if it comes into contact with hot engine parts.
You can be seriously burned.
