NOTE Damag e due to towing away at
excessively high speeds or over long dis-
tances The drivetrain could be damaged when towing
at e
xcessively high speeds or over long distan-
ces. 
A towing speed of 50 km/h must not be
e

xceeded. 
A towing distance of 50 km must not be
e

xceeded. &
WARNING Risk of accident when t
owing a
vehicle which is too heavy
If the vehicle to be tow-started or towed away
is hea
vier than the permissible gross mass of
your vehicle, the following situations can
occur:
= the towing eye may become detached.
= the vehicle/trailer combination may
swerve or overturn. 
Before tow-starting or towing away,
c

heck if the vehicle to be tow-started or towed away exceeds the permissible
g

ross mass. If a vehicle must be tow-started or towed away, its
per

missible gross mass must not exceed the per-
missible gross mass of the towing vehicle. 
Information on the permissible gross mass of
t

he vehicle can be found on the vehicle identi-
Ncation plate ( page 432). 
Vehicles with automatic transmission: do no
t
open the driver's door or front passenger
door; the transmission otherwise automati-
cally shiss to position j. 
Fit the towing eye ( pag
e 408).

e due to incorrect connec-
tion of the tow bar 
Only connect the tow rope or tow bar to
t
he towing eyes. 
Deactivate the automatic locking mechanism .

WARNING Risk of accident due t
o limited
safety-related functions during the towing
process
Safety-related functions are limited or no lon-
g
er available in the following situations:
= the vehicle is switched oM.
= the brake system or power steering system
is malfunctioning.
= the energy supply or the on-board electri-
cal system is malfunctioning.
When your vehicle is towed away, signiNcantly
more eMort may be required to steer and
brake than is normally required. 
Use a tow bar. 406

Notes on electrical fuses
&
WARNING Risk of accident and injur
y due
to overloaded lines
If you manipulate or bridge a faulty fuse or if
y
ou replace it with a fuse with a higher amper-
age, the electric line could be overloaded.
This could result in a Nre. 
Always replace faulty fuses with speci-
Ned ne

w fuses containing the correct
amperage. *
NOTE Damag
e due to incorrect fuses Using incorrect fuses can result in damage to
electr
ical components or systems or their
functions being considerably restricted. 
Use only fuses approved for Mercedes-
Benz wit

h the respective speciNed fuse
rating. Blown fuses must be replaced with fuses of the
same r

ating, which you can recognise by the col-
our and the label. The fuse ratings and further
information to be observed can be found in the
fuse assignment diagram.
Fuse assignment diagram: on the fuse box in the
boot (  page 411).
* NOTE Damag
e or malfunctions caused by
moisture Moisture may cause damage to the electrical
sy
stem or cause it to malfunction. 
When the fuse box is open, make sure
t

hat no moisture can enter the fuse box. 
When closing the fuse box, make sure
t

hat the seal of the lid is positioned cor-
rectly on the fuse box. Breakdown assistance

If the newly inserted fuse also blows, have the
cause tr aced and rectiNed at a qualiNed specialist
workshop.
Ensure the following before replacing a fuse:
= The vehicle is secured against rolling away.
= All electrical consumers are switched oM.
= The vehicle is switched oM.
The electrical fuses are located in various fuse
boxes: = Fuse box in the engine compartment on the
driver's side ( page 410)

Notes on noise or unusual handling characteris-
tics
Mak
e sure there are no vibrations, noises or
unusual handling characteristics when the vehicle
is in motion. This may indicate that the wheels or
tyres are damaged. Hidden tyre damage could
also be causing the unusual handling characteris-
tics.
If you suspect that a tyre is defective, reduce your
speed immediately and have the tyres and wheels
checked at a qualiNed specialist workshop. Notes on regularly inspecting wheels and tyres
&
WARNING Risk of injur
y due to damaged
tyres
Damaged tyres can cause tyre pressure loss. 
Check the tyres regularly for signs of
damag
e and replace any damaged tyres
immediately. &
WARNING Risk of aq
uaplaning due to
insuPcient tyre tread
*nsuPcient tyr
e tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
roads, especially when the speed of the vehi-
cle is not adapted to suit the conditions. 
Thus, you should regularly check the
tr

ead depth and the condition of the
tread across the entire width of all tyres.
Minimum tread depth for:
= Summer tyr

es: 3 mm
= M+S tyres: 4 mm 
For safety reasons, replace the tyres
bef
ore the legally-prescribed limit for the
minimum tread depth is reached. Carry out the following checks on all wheels regu-
lar
ly, at least once a month or as required, for
example, prior to a long journey or driving oM-
road:
= Check the tyre pressure (  page 413).=
V
isually inspect wheels and tyres for damage.
= Check the valve caps.
= Visual check of the tyre tread depth and the
tyre contact surface across the entire width.
The minimum tread depth for summer tyres is
3 mm and for winter tyres 4 mm. Notes on snow chains
&
WARNING Risk of accident due t
o incor-
rectly Ntted snow chains
If you have Ntt
ed snow chains to the front
wheels, they may drag against the vehicle
body or chassis components. 
Never Nt sno
w chains to the front
wheels. 
Only Nt sno
w chains on the rear wheels
in pairs. 412
Wheels and tyres

*
NOTE Damag e to components of the vehi-
cle body or chassis due to Ntted snow
chains If you
Nt sno
w chains to the front wheels of
4MATIC vehicles, you may damage compo-
nents of the vehicle body or chassis. 
Only Nt sno
w chains to the rear wheels
of 4MATIC vehicles. Observe the following notes when using snow
c

hains:
= Snow chains are only permissible for certain
wheel/tyre combinations. You can obtain
information about this from a Mercedes-Benz
Service Centre.
= For safety reasons, only use snow chains that
have been speciNcally approved for your vehi-
cle by Mercedes-Benz, or snow chains with
the same quality standard.
= Comply with the installation instructions of the
snow chain manufacturer.
= If snow chains are Ntted, the maximum per-
missible speed is 50 km/h. =
V
ehicles with Active Parking Assist: do not use
Active Parking Assist when snow chains are
Ntted.
% You can permanently limit the maximum
speed f

or driving with winter tyres
(  page 239).
% You can deactivate ESP n
t
o pull away
( page 232). This allows the wheels to spin,
achieving an increased driving force. Tyre pressure
Notes on tyre pressure
&
WARNING Risk of accident due t
o insuP-
cient or excessive tyre pressure
UnderinOated or o
verinOated tyres pose in par-
ticular the following risks:
= The tyres can burst.
= The tyres can wear excessively and/or
unevenly. =
The dr
iving characteristics as well as the
steering and braking characteristics may
be greatly impaired. 
Comply with the recommended tyre
pr

essure and check the tyre pressure of
all tyres, including the spare wheel, regu-
larly:
= mont
hly
= when the load changes
= before embarking on a longer journey
= if operating conditions change, e.g. oM-
road driving 
Adjust the tyre pressure, if necessary. Tyre pressure which is too high or too low can:
= Shor

ten the service life of the tyres.
= Cause increased tyre damage.
= Adversely aMect driving characteristics and
thus driving safety, e.g. due to aquaplaning. Wheels and tyres
