cluster displayPractical hints Car care Index ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in starter switch position 2
and should go out with the engine running.
When the ABS malfunction indicator lamp symbol and
warning in the instrument cluster remains illuminated
while the engine is running, it indicates that the ABS
has detected a malfunction and has switched off. In this
case, the brake system functions in the usual manner,
but without antilock assistance.
A malfunctioning ABS control unit can possibly affect
the operation of other systems (e.g. Navigation,
Automatic transmission). Be guided accordingly with
respect to the use of those systems and have the system
checked at your authorized Mercedes-Benz Center as
soon as possible.With the ABS malfunctioning, the BAS and ESP are also
switched off. The malfunction indicator lamps and
malfunction messages in the multifunction display
come on with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
See page 272 for notes on antilock brake system (ABS).

Electronic stability program (ESP) — warning lamp
The yellow ESP warning lamp in the
speedometer dial comes on with the
electronic key in starter switch position 2.
It should go out with engine running.
If the ESP malfunction indicator lamp remains
illuminated with the engine running, a malfunction has
been detected in the system. Pressing the accelerator
pedal will require greater effort. Only partial engine
output will be available.
See electronic stability program (ESP) on page 274 if the
warning lamp lights up or flashes when the vehicle is
moving.Seat belt nonusage warning lamp
With the electronic key in starter switch
position 2, the seat belt nonusage warning
lamp comes on, and a warning sounds for a
short time if the drivers seat belt is not fastened.
After starting the engine, the seat belt nonusage
warning lamp blinks for a brief period to remind the
driver and passengers to fasten seat belts.

AIRBAG OFF indicator lamp
The ü indicator lamp will light up for approximately
6 seconds when you turn the electronic key in starter
switch to position 1 or 2.
It does not light up if there is a fault in the system.
The ü indicator lamp stays lit as long as a
Baby Smart
TM child seat is properly installed on the
front passenger seat. It indicates that the front
passenger airbag is switched off.
See page 69 for BabySmart
TM airbag and its deactivation
system.
Baby Smart
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 ü 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.

* C = Category, see page 290.
1 The engine oil level must be checked immediately. See Engine oil
level indicator on page 141.
2 There is no oil in the engine. There is a danger of engine damage.3 There is a risk of damaging the engine or catalytic converter. The
engine oil level must be checked immediately. See Engine oil level
indicator on page 141.
4 The engine oil level has dropped to a critical level.
Check the engine oil level immediately. See Engine oil level
indicator on page 141 and check the engine for visible leakage (loss
of oil).
It may be that there is water in the engine oil. Have the engine oil
checked.
5 The measuring system is malfunctioning.
When the “ENGINE OIL LEVEL – CHECK LEVEL!”
message appears while the engine is running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning will first come on
intermittently and then stay on if the oil level drops
further.
If no oil leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The engine oil level warnings should not be ignored.
Extended driving with the symbol displayed could
result in serious engine damage that is not covered by
the Mercedes-Benz Limited Warranty.

Adding engine oil
1Oil dipstick
2Oil filler cap
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check engine oil level approximately 5 minutes after
stopping the engine, allowing for the oil to return to the
oil pan.The engine oil level can be checked by either the oil
dipstick or via the multifunction display in the
instrument cluster.
Wipe oil dipstick clean prior to checking the engine oil
level. Fully insert dipstick in tube, and remove after
three seconds to obtain accurate reading.
The oil level must be between the lower
mark (min) and the upper mark (max)
on the oil dipstick.
Fill quantity between upper and lower dipstick marking
level is approximately 2.1 US qt (2.0 l).
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could
cause damage to engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
See malfunction and warning messages on page 290 if
an engine oil level display appears on the multifunction
display when the engine is running.
Note:
See page 141 for engine oil level indicator display.
