Troubleshooting
220 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 0in the ignition lock before the next
starting attempt.
X Try to start the engine again (Y page 86). 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. 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 219).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 251).
If the engine does not start despite attempting to jump-start it:
X Consult a qualified specialist workshop. Vehicles with a petrol engine:
The engine is not running
smoothly and is misfiring. There is a malfunction in the
engine electronics or a mechani-
cal component of the engine con-
trol unit. X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist work-
shop.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it. Practical advice

Troubleshooting
226 Problem Possible cause/consequence Suggested solutions
You have lost the emergency key
element. X
Report the loss immediatel y to the vehicle insurers.
X If necessary, have the manual locks changed too. The key cannot be turned in the
ignition lock. The key has been in position
0for
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 250).
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 250).
or
X Jump-start the vehicle (Y page 251).
or
X Consult a qualified specialist workshop. Practical advice

Jump-starting
251
X
Connect positive terminal clamp 1and
secure the cover.
X Connect negative terminal clamp 3.
X Connect breather hose 4. Make sure that
a cell cap is fitted between battery 2and
breather hose 4.
i If the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:2
R set the time (Y page 106)
R reset the head restraints on the front
seats (Y page 61)
R reset the side windows ( Ypage 85) 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 may only be performed when
the engine and catalytic converter are cold.
R Do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R Jump-starting may only be performed with
batteries that have the same nominal volt-
age.
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. Only use the jump-starting pro-
cedure for the battery in the engine com-
partment. Do not use a rapid-charging device to start
the engine. 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 Apply the parking brake.
X Move the selector lever to P.
X Switch off all electrical consumers. Practical advice

Towing and tow-starting

The jump-starting terminals are on the left-
hand side in the engine compartment when
viewed in the direction of travel. 1
Cover
2 Positive terminal (+)
3 Negative terminal (-)
X Lift up the cover of positive terminal 2on
your own vehicle.
X Connect positive terminal 2on your vehi-
cle to positive terminal of the donor battery
using the jump lead, beginning with your
own battery.
X Start the engine of the donor vehicle and
run it at idling speed.
X Connect negative terminal 3of the donor
battery to negative terminal of your vehi- cle's battery using the jump lead, connect-
ing 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 negative
terminals 3first, and then from the posi-
tive terminals 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
Points to remember
G
Risk of accident
If you have the vehicle towed, you must use
a rigid towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the voltage sup-
ply or the vehicle's electrical system.
The electric power steering and the brake
force booster do not work when the engine
is not running. Greater braking force will
then be required and brake pedal travel will
be longer. If necessary, depress the brake
pedal with full force.
Do not tow the vehicle if the key cannot be
turned in the ignition lock. If this is the case,
the steering is locked and the vehicle can-
not be steered.
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. Practical advice

Towing and tow-starting
253
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.
! 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 transfer case can be shifted into neu-
tral N, you can tow the vehicle.
R If the transfer case cannot be shifted into
neutral N, you can tow the vehicle with one
axle raised. Please bear the following in
mind: -
remove the propeller shaft between the
transfer case and the rolling axle.
- turn the key to position 1in the ignition
lock.
R If the engine does not start, try jump start-
ing (Y page 251).
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 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
i Switch off the automatic locking feature
before the vehicle is towed (Y page 108).
You could otherwise be locked out when
pushing or towing the vehicle. Towing eye
Towing eye, front The vehicle is equipped with two towing eyes.
These are located at the front, under the
bumper.
