Troubleshooting
255Engine
Problem Possible cause/consequence Suggested solutions
The engine will not start. HOLD is activated. X
Deactivating HOLD (Y page 145).
X Start the engine again. The engine will not start. You can
hear
the starter motor operating. R
There may be a malfunction in
the engine electronics.
R There may be a malfunction in
the fuel supply. X
Turn the key back to position 0 in the ignition lock before the next
starting attempt.
X Try to start the engine again (Y
page 101). 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. Vehicles with a diesel engine:
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 254). 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 291).
If the engine does not start despite attempting to jump-start it:
X Consult a qualified specialist workshop. Practical advice

0 for
a considerable time. X
Remove the key and reinsert it into the ignition lock.
X Check the starter battery and recharge it if necessary
(Y page 290).
X Start the engine. The on-board voltage is too low. X
Switch off non-essential consumers, e.g. seat heating* or interior
lighting, and try to turn the key again.
If this does not work:
X Check the starter battery and recharge it if necessary
(Y page 290).
or
X Jump-start the vehicle (Y page 291).

Jump-starting
291
X
Charge the battery. Observe the notes in
the operating instructions for your battery
charger.
X Refit the charged battery.
To do this, follow the steps described in
"Removing the battery"
(Y page 290) in
reverse order.
! Do
not fit refillable batteries without elec-
trostatic protection. The electrostatic dis-
charge could otherwise cause the battery
to explode. The battery acid released could
cause damage to your vehicle.
Further information on electrostatic protec-
tion (Y page 289). G
Risk of injury
Battery acid is caustic. Avoid contact with
the skin, eyes or clothing. Reconnecting the battery
! Always reconnect the battery in the
sequence

described below. Never swap the
terminal clamps. You may otherwise dam-
age the vehicle electronics.
X Switch off all electrical consumers.
X Connect the positive terminal clamp and
secure the cover.
X Connect the negative terminal clamp.
X Connect the breather hose. Make sure that
a

cell cap is fitted between the battery and
the breather hose.
X Refit the electrostatic protection if neces-
sary ( Y page 289).
i If
the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:
R Set the time (Y page 125).
R Reset the sliding/tilting sunroof*
(Y page 171).
R Reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once ( Y page 84). Jump-starting
If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle

or from an external battery using jump
leads.
Observe the following points:
R Jump-starting must only be performed
when the engine and catalytic converter
are cold.
R Do not start the engine if the battery has
frozen. Thaw the battery out first.
R Jump-starting may only be performed from
12V batteries.
R Only use jump leads which are protected
against polarity reversal and which have a
sufficient cross-section and insulated ter-
minal clamps.
i Jump leads which are protected against
polarity reversal and further information
about jump-starting can be obtained from
any Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts.
Never start the vehicle using a rapid battery
charger. Practical advice

Jump-starting
292 G
Risk of injury
There is a risk of acid burns when jump-
starting a vehicle due to the gases which
escape from the battery. Do not lean over
the battery while the engine is being jump-
started. G
Risk of explosion
Gases escaping from the battery during
jump-starting may cause minor explosions.
Avoid creating sparks. Keep naked flames
away from the battery, and do not smoke.
Comply with safety precautions and take
protective measures when handling batter-
ies. You will find these under “Battery” in
the index.
X Make sure that the two vehicles do not
touch.
X Depress the parking brake.
X Move the selector lever to P.
X Switch off all electrical consumers.1 Positive terminal of your vehicle's battery
2 Positive terminal of donor battery
3 Negative terminal of donor battery
4 Connection for suitable earth point on the
vehicle
X Connect positive contact on your vehi-
cle 1 to positive terminal of the donor
battery 2 using the jump lead, connecting
the jump lead to your own battery first.
X Start the engine of the donor vehicle and
run it at idling speed.
X Connect the negative terminal of the donor
battery 3 and the earth contact on your
vehicle 4 using the jump lead, connecting
the jump lead to the donor battery first.
X Start the engine. X
Electrical consumers can be switched on
again. Do not switch the lights on however,
as this will overload the battery.
X Remove the jump lead from the suitable
earthing point 4 and negative termi-
nal 3 first, then from the positive termi-
nals 1 and 2, each time disconnecting
from the battery on your own vehicle first.
X Have the battery checked at a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre.

Towing and tow-starting
293Towing and tow-starting
Points to remember
G
Risk of accident
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine is not running
R there is a brake system malfunction
R the voltage supply or the vehicle's elec-
trical system is damaged
There
is no power assistance for the steer-
ing when the engine is not running. G
Risk of accident
The vehicle is braked when HOLD is activa-
ted.
Therefore, deactivate HOLD if the vehi-
cle is to be towed.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehi-
cle.
It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirements
in all countries concerned. !
When towing, pull away slowly and with-
out

jerking. If the tractive power is too high,
the vehicles could be damaged. Do not use
the towing eye for recovery.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission
must not be tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 291).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
R If the vehicle has suffered transmission
damage, only tow it with the propeller shaft
disconnected.
R The selector lever must be in position N on
vehicles with automatic transmission. R
If you are towing the vehicle over a consid-
erable distance, this may only be done with
the rear axle raised.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
-You cannot switch on the ignition
- You cannot move the selector lever to N
- You have no support when braking
i Switch off the automatic locking feature
before the vehicle is towed (Y page 127).
You could otherwise be locked out when
pushing or towing the vehicle. Practical advice
