362 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on ignition
(
page 36), have the respective bulb
checked and replaced if necessary.
Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp comes on
while driving.
The ABS has detected a malfunction
and has switched off. The BAS and
ESP
® are also switched off (see mes-
sages in display).
The brake system is still functioning
normally but without the ABS avail-
able.
If the ABS control unit is malfunction-
ing, other systems such as the
automatic transmission* may also be
malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 368).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS has switched
off.
The battery might not be charged suf-
ficiently.
Switch off electrical consumers that
are currently not needed, e.g. seat
heating*.
If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.

The yellow engine
malfunction indicator
lamp comes on while
driving.
There is a malfunction in:
the fuel management system
the ignition system
the emission control system
systems which affect emissions
Such malfunctions may result in ex-
cessive emissions values and may
switch the engine to its limp-home
(emergency operation) mode.
Have the vehicle checked as soon as possible
by an authorized Mercedes-Benz Center.
An on-board diagnostic connector is used by
the service station to link the vehicle to the
shop diagnostics system. It allows the accu-
rate identification of system malfunctions
through the readout of diagnostic trouble
cod es . It is l oc ate d i n the f ront l ef t a rea of the
footwell near the hood release.
Your fuel tank is empty.
After refueling start, turn off and restart the
engine three or four times in succession.
The limp-home mode is canceled. You do not
need to have your vehicle checked.
Additionally you see
the message
Check
gas cap
See Operator’s
Manual
in the multi-
function display.
A loss of pressure has been detect-
ed in the fuel system. The fuel cap
may not be closed properly or the
fuel system may be leaking.
Check the fuel cap (
page 304).
If it is not closed properly:
Close the fuel cap.
If it is closed properly:
Have the fuel system checked by an autho-
rized Mercedes-Benz Center.

What to do if …
On the pages that follow, you will find
a compilation of the most important warn-
ing and malfunction messages that may
appear in the multifunction display.
For your convenience the messages are
divided into two sections:
Text messages (
page 370)
Symbol messages (

Raising retractable hardtop manuallyWarning!
G
If the retractable hardtop does not com-
pletely open or close, the roof hydraulics will
lose pressure and the retractable hardtop is
lowered
after approximately 7 minutes when the
ignition is switched on
after approximately 15 seconds when
the ignition is switched off
Shortly before the hardtop is lowered, a
warning will sound. In the multifunction dis-
play you will seeK and the message
Retractable roof being opened
.
Properly lock retractable hardtop before
continuing to drive (
page 252).
Warning!
G
Manually closing the retractable hardtop is a
complicated and technically demanding pro-
cedure and should only be performed by an
authorized Mercedes-Benz Center or quali-
fied technician. Attempting to manually
close the retractable hardtop may cause
damage to the retractable hardtop and/or
personal injury.
Warning!
G
To prevent possible accidents, drive the ve-
hicle only with the retractable hardtop either
completely closed and locked, or fully low-
ered into its storage compartment.

Flat tire
After attaining a tire inflation pressure
of 26 psi (1.8 bar), press 0 on electric
air pump switch8.
The electric air pump should now be
switched off.
Turn the SmartKey in the ignition to
position0 (
page 36).
Detach the electric air pump.
The air hose may still be hot. Please ex-
ercise appropriate caution.
Store the electrical plug and the air
hose behind the flap and place the
electrical air pump back in the trunk.
Close the trunk lid.
Drive off immediately.
The TIREFIT sealant will distribute itself
evenly inside the tire.
After driving the vehicle for an initial
10 minutes, check the tire inflation
pressure using pressure gauge 9 on
the air pump.
Warning!
G
If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, tire is too severely damaged
for TIREFIT to provide a reliable tire repair.
In this case, TIREFIT cannot properly seal
the tire.
Do not drive the vehicle.
Contact the nearest Mercedes-Benz Center
or call Roadside Assistance.
Warning!
G
Do not exceed vehicle speed of
50 mph (80 km / h). A TIREFIT repair is not
designed to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.
Warning!
G
If tire inflation pressure has fallen below
20 psi (1.3 bar) do not continue to drive the
vehicle.
Park your vehicle safely away from the road-
way and contact the nearest authorized
Mercedes-Benz Center or Roadside
Assistance.
If tire inflation pressure is at least
20 psi (1.3 bar), inflate tire to correct pres-
sure (see placard on the driver’s door
B-pillar), and drive vehicle to nearest tire re-
pair facility to have tire repaired or replaced.
Recommended duration of use:
300 miles (500 km) at 50 mph (80 km/h)
with the recommended tire inflation pres-
sure.
427 Practical hints
Towing the vehicle
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:
the engine will not run
there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.iTo signal turns while being towed with
the hazard warning flasher in use,
switch on ignition and activate the
combination switch for the left or right
turn signal in the usual manner – only
the selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 101).
Switch off the tow-away alarm
(
page 88).
The vehicle should only be towed using
a properly installed towing eye bolt.
Never attach a tow cable, tow rope or
tow rod to the vehicle chassis, frame or
suspension parts.
