Risk of accident
ABS (Anti-lock Brake System) is
deactivated due to a fault. There-
fore, ESP ®

Program), BAS (Brake Assist), the
steering assistant STEER CON-
TROL, the hill start assist and the
tyre pressure loss warning sys-
tem are also deactivated.
The brake system continues to
function normally, but without
electronic support. The wheels
could therefore lock if you brake
hard.
If the ABS control unit is faulty,
other systems may also not be
available: e.g. Parktronic sys-
tem*, the navigation system* or
the Autotronic*. X
Drive on carefully.
X Observe the additional messages in the multi-function display

Problem Possible cause/consequence Suggested solutions
The engine will not start. You can
hear the starter motor operating. R
The engine electronics system
is malfunctioning.
R There is a malfunction in the
fuel supply.
R The on-board voltage is too low
because the starter batter y is
too weak or discharged. X
Turn the key back to position 0(Y page 62) in the ignition lock
before the next starting attempt.
X Try to start the engine again (Y page 87). When doing so, remember
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 232).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 266).
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
