General notes
H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man- ner.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz. Washing the vehicle and cleaning the
paintwork
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
! If the HOLD function is activated, the vehi-
cle brakes automatically in certain situa-
tions.
To prevent damage to the vehicle, deacti-
vate the HOLD function in the following or
other similar situations:
R when towing the vehicle
R in the car wash
! Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
! When washing your vehicle in a tow-
through car wash, make sure that the selec- tor lever is in position N, otherwise the
vehicle could be damaged.
! Make sure that:
R the side windows are fully closed.
R the ventilation/heating is switched off
(the OFF button has been pressed/the
airflow control is set to position 0).
R the windshield wiper switch is at position
0.
The vehicle may otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce 272

Important safety notes
G
WARNING
Functions relevant to safety are restricted or
no longer available if:
R the ignition is switched off
R the brake system or the power steering is
malfunctioning
R there is a malfunction in the power supply
or the vehicle's electrical system
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely. G
WARNING
You can no longer steer the vehicle if the
steering wheel lock has been engaged. There is a risk of an accident.
Always switch off the ignition when towing the
vehicle with a tow cable or a tow 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 the towing eye could detach itself
R the vehicle/trailer combination could roll-
over.
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 identification plate (Y page 330).!
When COLLISION PREVENTION ASSIST
PLUS or the HOLD function is activated, the
vehicle brakes automatically in certain sit-
uations. To avoid damage to the vehicle,
deactivate these systems in the following
or similar situations:
R when towing the vehicle
R in the 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
an authorized Mercedes-Benz Center for
this purpose.
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
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 Ensure that the tow cable is not longer
than legally permitted. Mark the tow
cable in the middle, e.g. with a white
cloth (30 x 30 cm). This will make other
road users aware that the vehicle is being
towed.
R Only secure the tow cable to the towing
eye.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain a
distance so that the tow rope does not
sag.
R Do not use steel cables or chains to tow
your vehicle. You could otherwise dam-
age the vehicle.
! Do not use the towing eyes for recovery
purposes as this could damage the vehicle. If in doubt, recover the vehicle with a crane. 292

!
When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the front axle must be
raised or the entire vehicle raised and
transported.
! Do not tow with sling-type equipment.
This could damage the vehicle.
! To tow vehicles with KEYLESS-GO, use
the SmartKey instead of the Start/Stop
button. The transmission may otherwise
shift to position Pwhen you open the driv-
er's or front-passenger door, which could
damage the transmission.
Observe the legal requirements for the rele-
vant countries when towing away.
Make sure that no charging cable is plugged
in. The parking lock cannot be released if a
charging cable is plugged in.
It is better to have the vehicle transported
than to have it towed away.
If the vehicle can no longer be driven because
of an accident or breakdown, you have the
following 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:

WARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper- age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. an authorized
Mercedes-Benz Center.
! 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". Otherwise, components or systems
could be damaged.
The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions stop
operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe- cialist workshop, e.g. an authorized
Mercedes-Benz Center. Before changing a fuse
X Secure the vehicle against rolling away
(Y page 153).
X Switch off all electrical consumers.
X Vehicles without KEYLESS-GO: remove

X Vehicles with KEYLESS-GO start-func-
tion or KEYLESS-GO: open the driver's
door.
The on-board electronics now have status
0. This is the same as the SmartKey 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
