The power assistance for the steering and the
brake force booster do not work when the
engine is not running. You will need more
force to steer and brake, you may have to
depress the brake pedal with maximum force.
Before towing away,m ake sure that the steer-
ing can be moved and is not locked.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle. G
WARNING
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate HOLD and DISTRONIC PLUS if the
vehicle is to be towed.
It is better to have the vehicle transported
than to have it towed.
! You may tow the vehicle for amaximum
of 50 km. Atowing speed of 50 km/h must
not be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported.
! Only secure the tow rope or towing bar to
the towing eyes. The vehicle may otherwise
be damaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with acrane.
! Pull away smoothly when towing away or
tow-starting avehicle. If the tractive power
is too high, the vehicles could be damaged.
! On vehicles with KEYLESS-GO, use the
key instead of the Start/Stop button. Turn
the key to position 2in the ignition lock and
shift the automatic transmission to N.
Then, turn the key back to 0and leave it in
the ignition lock. When towing
avehicle with an automatic
transmission, the transmission must be in
position N.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the key in the ignition lock to
position 2
R cannot shift the transmission to position
N on vehicles with automatic transmission
Vehicles with automatic transmission:
release the selector lever lock manually to
move it out of position P(Y page 160).
i Before the vehicle is towed, switch off the
automatic locking feature (Y page 78). You
could otherwise be locked out when push-
ing or towing the vehicle.
Deactivate tow-away protection
(Y page 68) before the vehicle is towed. Fitting/removing the towing eye
Fitting the towing eye Vehicles with
atrailer tow hitch: if you intend
to use the vehicle for towing, fold out the ball
coupling and connect the towbar to it
(Y page 206).
X Remove the towing eye from the vehicle
tool kit (Y page 295). G
WARNING
The exhaust tail pipe may be hot. You could
burn yourself if you touch the tail pipe. Be
particularly careful when removing the rear
cover.
The mountings for the removable towing eyes
are located in the bumpers. They are at the
front and at the rear, under the covers. Towing and tow-starting

Transporting the vehicle
The towing eyes or trailer tow hitch can be
used to pull the vehicl eonto atrailer or trans-
porter if yo uwishtot ransport it.
X Vehicle swithm anual transmission:
shift to neutral.
X Vehicle switha utomatic transmission:
tur nthe key to position 2in the ignition
lock.
X Move the selector lever to N.
As soon as the vehicle is loaded:
X Prevent the vehicle from rolling away by
applying the parking brake.
X Vehicles with manualt ransmission:
shift to first gear or reverse gear.
X Vehicles with automatic transmission:
move the selector lever to P.
X Turn the key in the ignition lock to position
0 and remove the key from the ignition
lock.
X Secure the vehicle.
! Only lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicle
such as axle or steering components. Oth-
erwise, the vehicle could be damaged. Tow-starting (emergency engine
starting)
When tow-starting, it is important that you
observe the safety instructions (Y page 310)
and the legal requirements in each respective
country.
! Vehicles with automatic transmission
must not be tow-started. The transmission
may otherwise be damaged.
Before tow-starting the following conditions
must be fulfilled:
R the battery is connected.
R the engine has cooled down.
R the catalytic converters have cooled down. X
Switch on the hazard warning lamps
(Y page 117).
X Fit the towing eye (Y page 311).
X Secure the rigid towing bar or the towing
rope.
X Depress and hold the brake pedal.
X Turn the key to position 2in the ignition
lock.
X Depress the clutch pedal and keep it
depressed.
X Shift to neutral.
X Release the brake pedal.
X Tow-start the vehicle.
X Engage second gear.
X Release the clutch pedal slowly;don ot
operate the accelerator pedal while doing
so.
The engine is started.
X Depress the clutch pedal and shift to neu-
tral.
X Stop at asuitable place.
X Apply the parking brake.
X Remove the rigid towing bar or towing rope.
X Remove the towing eye (Y page 312).
X Switch off the hazard warning lamps. Electrical fuses
Important safety notes
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows ,all th ecom po-
nent sont hecircuit and their function sstop
operating. G
WARNING
Only use fuses that have been approve dfor
Mercedes-Ben zvehicles and which have the
correct fuse ratin gfor the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Otherwise, acircuit overload
could cause afire. Have the cause traced and
rectified at aqualified specialist workshop,
e.g. aMercedes-Benz Service Centre. Electrical fuses

is kept open continuously, which may lead to
air loss. G
WARNING
Should the tyre pressure drop repeatedly:
R chec kthe tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only avalve cap approved
by Mercedes-Ben zisfitted on the tyre
valve.
Tyre pressures that are too low have anega-
tive effect on vehicle safety, which could lead
you to cause an accident.
If possible, only correct tyre pressures when
the tyres are cold. The tyres are cold when
the vehicle has been parked for at least three
hours or has been driven less than 1.5 km.
Depending on the ambient temperature, the
speed you are driving at and the load on the
tyres, the tyre temperature and thus the tyre
pressure may change by approximately
10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have anegative effect on handling charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. H
Environmental note
Check the tyre pressure regularly,atl east
every 14 days. Tyrep
ressur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in
atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorresponding warning
message will appearint he multifunction dis-
play. G
WARNING
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.
In the event of asudden loss of pressure, bring
the vehicle to ahalt by braking carefully. Do
not make any sudden steering movements
when doing so.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditionsa re wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof). 322
