Important safety notes G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving
characteristics change. If you exceed the
maximum roof load, the driving
characteristics, as well as steering and
braking, will be greatly impaired. There is a
risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
! Mercedes-Ben zrecommends that you
only use roof carriers that have been tested and approved for Mercedes-Benzv
ehicles.
This helps to preven tdamage to the
vehicle.
Positio nthe load on the roof rack in such a
way that the vehicle will not sustain
damage even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is
installed you can:
R open the panorama roof with power tilt/
sliding panel fully
R open the trunk lid fully
! To avoid damaging or scratching the
covers, do not use metallic or hard objects
to open them.
The maximum roof load is 220 lbs(100 kg).
An incorrectly secured roof carrier or roof
load could become detached from the
vehicle. Therefore, always comply with the
installation instructions supplied by the
manufacturer of the roof carrier.

Important safety notes
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
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towing eye could detach itself
R the vehicle/trailer combination could
rollover.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the
permissible gross weight of your vehicle.
Information on your vehicle's gross vehicle
weight rating can be found on the vehicle
identification plate (Y page 332).
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
R when towing the vehicle
R in the car wash
! The vehicle can be towed a maximum of
30 miles (50km). The towing speed of
30 mph (50 km/h) must not be exceeded. If the vehicle has to be towed more than
30 miles
(50km), the entire vehicle must be
raised and transported.
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
! Do not use the towing eyes for recovery
purposes 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.
! Do not tow with sling-type equipment.
This could damage the vehicle.
! On vehicles with KEYLESS-GO, use the
SmartKey instead of the Start/Stop
button. Turn the SmartKey to position 2in
the ignition lock and shift the automatic
transmission to N. Then, turn the SmartKey
back to 0and leave it in the ignition lock.
It is better to have the vehicle transported
than to have it towed.
The automatic transmission must be in
position Nwhen the vehicle is being towed.
The battery must be connected and charged.
Otherwise, you:
R cannot turn the SmartKey to position 2in
the ignition lock
R cannot shift the automatic transmission to
position N
Release the selector lever lock manually to
move it out of position P(Ypage 145).
i Deactivate the automatic locking feature

Transporting the vehicle
The towing eye can be used to pull the vehicle
onto a trailer or transporter for transporting
purposes.
X Turn the SmartKey to position 2in the
ignition lock.
X Move the selector lever to N.
As soon as the vehicle has been loaded:
X Prevent the vehicle fro mrolling away by

X Turn the SmartKey to position 0in the
ignition lock and remove the SmartKey
from the ignition lock.
X Secure the vehicle.
! You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components.O therwise,
the vehicle could be damaged. Notes on 4MATIC vehicles
! Vehicles with 4MATIC must not be towed
with eithe rthe front or the rear axle raised,
as doing so will damage the transmission.
If the vehicle has transmission damage or
damage to the front or rear axle, have it
transported on a transporter or trailer.
In the event of damage to the electrical
system
If the battery is defective, the automatic
transmission will be locked in position P. To
shift the automatic transmission to position
N, you must provide power to the vehicle's
electrical system in the same way as when
jump-starting (Y page 288).
Have the vehicle transported on a transporter
or trailer. Tow-starting (emergency engine
starting)
! Vehicles with automatic transmission
must not be started by tow-starting. This
could otherwise damage the transmission.
You can find information on "Jump-starting"
at (Y page 288). Fuses
Important safety notes
G
WARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher
amperage, 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.
! Only use fuses that have been approved
for Mercedes-Ben zvehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or
systems could be damaged.
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows, all the
components on the circuit and their functions
stop operating.
Blown fuses must be replace dwith 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
specialist workshop, e.g. an authorized
Mercedes-Ben zCenter. Before changing a fuse
