Important safety notes
G
WARNING
Safety relevant functions are restricted or no
longer available if:
R the ignition is switched off
R the brake system or power steering is mal-
functioning
R there is a malfunction in the voltage supply
or the vehicle's electrical system.
When your vehicle is towed, you may require
considerably more effort to steer and brake.
There is a risk of an accident.
In such cases use a rigid towing bar. Before
towing away, make sure the steering moves
freely. G
WARNING
If the steering wheel lock is engaged, the vehi- cle can no longer be steered. There is a risk of
an accident.
Always switch on the ignition when towing
with a tow rope or a towing bar. G
WARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible gross weight of your vehicle, the:
R towing eye may be torn off
R car/trailer combination may swerve or
even overturn
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Details on the permissible gross vehicle weight
of your vehicle can be found on the vehicle iden-
tification plate (Y page 281). !
When COLLISION PREVENTION ASSIST
PLUS or the HOLD function is activated, the
vehicle brakes automatically in certain situa-
tions. To avoid damage to the vehicle, deac-
tivate these systems in the following or simi-
lar situations:
R when towing away
R in a car wash
! Make sure that the electric parking brake is
released. If the electric parking brake is faulty, visit a qualified specialist workshop.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose.
! Only secure the tow rope or towing bar to
the towing eyes. The vehicle may otherwise
be damaged.
! Observe the following points when towing
with a tow rope:
R secure the tow rope on the same side on
both vehicles.
R make sure that the tow rope is not longer
than legally permitted. Mark the tow rope in
the middle, e.g. with a white cloth
(30 x 30 cm). This makes other road users
aware that a vehicle is being towed.
R only secure the tow rope to the towing eye.
R observe the brake lamps of the towing vehi-
cle while driving. Always maintain a dis-
tance so that the tow rope does not sag.
R do not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
! Do not use the towing eyes for recovery pur-
poses as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
! You may tow the vehicle for a maximum of
50km. A towing speed of 50 km/h must not
be exceeded.
For towing distances over 50 km, the front
axle or the entire vehicle must be raised and
transported.
! When towing vehicles with KEYLESS-GO,
use the key instead of the Start/Stop button. The transmission may otherwise shift to posi- tion Pwhen you open the driver's or front- 260

passenger door, which could damage the
transmission.
Observe the legal requirements for the relevant countries when towing.
Make sure that no charging cables are connec-
ted. The parking lock cannot be released if a
charging cable is connected.
It is better to have the vehicle transported than
to have it towed.
If the vehicle can no longer be driven because of
an accident or breakdown, you have the follow- ing options:
R transporting the vehicle
As a rule, you should have the vehicle trans-
ported.
R towing the vehicle with a tow rope or tow bar
Only tow the vehicle in exceptional cases.
Observe the following notes.
The vehicle may not be towed and must always be transported if:
R the multifunction display is not working
R one of more of the following warning lamps is
lit up:
- Drive system
- 12 V battery
R one or both of the following display messages
have appeared:
- Stop Switch engine off
Stop Switch engine off
- Without changing gear, consult Without changing gear, consult

R you have to tow the vehicle over a longer dis-
tance than 50 km.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the key to position 2in the igni-
tion lock
R cannot release the electric parking brake
R cannot move the transmission to position N
The function of the electric parking brake and
the parking lock is dependent on the on-board
voltage.
If the on-board voltage is low or if there is a sys- tem malfunction:
R it may not be possible to apply the released
parking brake or
R it may not be possible to shift the transmis-
sion to position P Switch off non-essential consumers, e.g. the
radio.
Deactivate the automatic locking feature before
towing the vehicle (Y page 187). You could oth-
erwise be locked out when pushing or towing
the vehicle.

Important safety notes
G
WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified newfuses of the correct amperage.
Blown fuses must be replaced with fuses of the same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified special- ist workshop, e.g. a Mercedes-Benz Service
Centre.
! Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Only use fuses marked with an "S". Compo-
nents or systems could otherwise be dam-
aged.
The fuses in your vehicle disconnect faulty cir-
cuits. If a fuse blows, all the components on the circuit and their functions will fail. Before replacing a fuse
X Safeguard the vehicle against rolling away
(Y page 145).
X Switch off all electrical consumers.
X Vehicles without KEYLESS-GO: remove the
key from the ignition lock.
X Vehicles with KEYLESS-GO start-function
or KEYLESS-GO: open the driver's door.
The on-board electronics now have status 0.
This is the same as the key having been
removed.
The fuses are located in various fuse boxes: R fuse box in the engine compartment on the
left-hand side of the vehicle, when viewed in
the direction of travel
