Risk of accident and injury
The operating safety of your vehicle could be compromised if service work is carried out improperly. You could lose control of the vehicle,
thereby causing an accident. Safety systems may also not be able to protect you or others as intended.
Always have maintenance work carried out at a qualified specialist workshop which has the necessary specialist knowledge and tools to
carry out the work required.
Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.
In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. Display messages Possible cause/consequence Possible solution

Problem Possible cause/consequence Suggested solutions
-
The yellow ABS warning
lamp comes on while the
engine is running. G
Risk of accident
ABS has been deactivated due to
a malfunction. Therefore, Brake
Assist, ESP ®
and PRE-SAFE ®
are,
for example, also deactivated.
The brake system continues to
function normally, but without
electronic support. The wheels
could therefore lock if you brake
hard, for example. X
Drive on carefully.
X Observe the additional messages in the multi-function display
(Y page 255).
X Visit a qualified specialist workshop as soon as possible. -
The yellow ABS warning
lamp comes on while the
engine is running. G
Risk of accident
ABS has been deactivated due to
undervoltage. It is possible that
the battery is not being charged.
Therefore, the following systems
are, for example, also deactiva-
ted: Brake Assist, ESP ®
, BAS and
PRE-SAFE ®
.
The brake system continues to
function normally, but without
electronic support. The wheels
could therefore lock if you brake
hard, for example. X
Switch off consumers that are not required, e.g. reading lamps,
interior lighting, etc.
ABS will be available again as soon as the vehicle's electrical sys-
tem voltage increases. Practical advice

290 Engine
Problem Possible cause/consequence Suggested solutions
The engine will not start. You can
hear the starter motor operating. R
There is a malfunction in the
engine electronics.
R There is a malfunction in the
fuel supply. X
Turn the key back to position 0(Y page 76)in the ignition lock
before the next starting attempt.
X Try to start the engine again (Y page 110). When doing so, remem-
ber that excessively long and frequent attempts to start the engine
will drain the battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop. The engine will not start. You can
hear the starter motor operating.
The reserve fuel warning lamp is
on and the fuel gauge shows 0. The fuel tank has been run dry. X
Refuel the vehicle.
X Bleed the fuel system (Y page 289).The engine will not start. You can-
not hear the starter motor oper-
ating. The on-board voltage is too low
because the starter battery is too
weak or discharged. X
Jump-start the vehicle (Y page 329).
If the engine does not start despite attempting to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to
a thermal load that was too high. X
Allow the starter motor to cool down for approximately two
minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult a qualified specialist workshop. Practical advice

317Changing a wheel/fitting the emer-
gency spare wheel*
G
Risk of accident
The wheel dimensions and tyre size of the
emergency spare wheel* may differ from
those of the standard wheels.
The handling characteristics of your vehicle
will change if you fit an emergency spare
wheel*. Adapt your style of driving accord-
ingly.
You may only use the emergency spare
wheel* for a short while. Do not exceed the
maximum speed of 80 km/h and do not
deactivate ESP ®
.
Never drive the vehicle with more than one
emergency spare wheel* fitted. G
Risk of accident
Have the emergency spare wheel*
replaced as soon as possible at a qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety- related systems must be carried out at a
qualified specialist workshop.
Preparing the vehicle X
Prepare the vehicle as described
(Y page 313).
X If a trailer is coupled, uncouple it.

position.
X Take the following from the stowage well
beneath the luggage compartment floor:
R
the emergency spare wheel
R the electric air pump
R the vehicle tool kit
R the wheel chock
R the jack
X Secure the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
items under the front and rear of the wheel
that is diagonally opposite the wheel you
wish to change. Securing a vehicle on level ground (example illus-
tration)
X
On downhill gradients: place chocks or
similar items under both wheels of the
