Floormat on the driver's side
GWarning!
Whenever you are using a floormat, make sure
there is enough clearance and that the
floormat is securely fastened.
The floormat should always be securely
fastened using the fastening equipment.
Before driving off, check that the floormat is
securely in place and adjust it if necessary. A
loose floormat could slip and hinder proper
functioning of the pedals.

carefully after washing the vehicle until the
brakes have dried.GRisk of accident
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an
automatic car wash.
You can wash the vehicle in an automatic car
wash from the very start.
! It is preferable to use car washes with
adjustable 26
high-pressure precleaning. In
car washes that use high water pressures,
there is a risk that a small amount of water
may leak into the vehicle.
! Cabriolet: do not treat the vehicle with
hot wax under any circumstances.
! Cabriolet: pull the SmartKey out of the
ignition lock when washing the vehicle. This
ensures that the wind deflector on the
windshield is retracted. The wind deflector
may otherwise be damaged.
! 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.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! In car washes with a towing mechanism,
make sure that the automatic transmission
is in transmission position N, otherwise the
vehicle could be damaged.
! Make sure that the side windows are
completely closed, that the ventilation/
heating is switched off and that the
windshield wiper switch is set to 0.
Otherwise, the rain/light sensor could be
activated, triggering unintended wiper
movements. This can cause damage to the
vehicle.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the
windshield.
Washing by hand
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Also, clean the insides of the wheels when
washing the underbody of the vehicle.
XDo not use hot water and do not wash the
vehicle in direct sunlight.XUse a soft car sponge for cleaning.XUse a gentle cleaning agent, e.g. a
Mercedes-Benz approved car shampoo.XWash down the vehicle with a gentle water
jet.XDo not point the water jet directly at the air
inlets.XUse plenty of water and rinse the sponge
frequently.XRinse the vehicle with clean water and dry
it thoroughly with a chamois.XDo not allow the cleaning agent to dry on
the paintwork.
Power washers
GWarning!
Do not use power washers with circular-jet
nozzles (dirt grinders) to clean your vehicle, in
particular the tires. You could otherwise
damage the tires and cause an accident.
! Maintain the distance between the
vehicle and the nozzle of the power washer
at 11.8 in (30 cm). Information about the
correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around
when cleaning your vehicle.

Towing and tow-starting
Important safety notes
GWarning
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine will not run.
R there is a malfunction in the brake system.
R there is a malfunction in the power supply
or the vehicle's electrical system.
With the engine not running, there is no power
assistance for the brake and steering
systems. You will then need considerably
more force to steer and to brake and the
brake pedal travel will be longer. If necessary,
depress the brake pedal with maximum force.
Before towing away, make sure that the
steering can be moved and is not locked.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum
permissible gross vehicle weight of your
vehicle.
GWarning
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 only tow the vehicle a maximum
distance of 30 miles (50 km). A towing
speed of 30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 km), the vehicle must loaded onto a
transporter.
! Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could
be damaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! Drive slowly and smoothly when towing.
Excessive tractive power could otherwise
damage the vehicles.
! 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 2 in
the ignition lock and shift the automatic
transmission to N. Then, turn the SmartKey
back to 0 and leave it in the ignition lock.
! Vehicles with automatic transmission
must not be started by tow-starting. This
could otherwise damage the transmission.
The automatic transmission must be in
position N when the vehicle is being towed.
Make sure that the battery is connected and
charged. You will otherwise not be able to:
R turn the SmartKey to position 2 in the
ignition lock.
R shift the automatic transmission to
position N.
Vehicles with automatic transmission:
manually release the selector lever lock in
position P (Y page 162).
i Switch off the automatic locking feature
before the vehicle is towed ( Y page 81).
Otherwise, you could lock yourself out of
the vehicle when pushing or towing the
vehicle.
Installing/removing the towing eye
Installing the towing eye
XRemove the towing eye from the vehicle
tool kit ( Y page 287).GWarning
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.

front and at the rear, behind the covers.
Example: Cabriolet
XPress the mark on cover : inwards, in the
direction of the arrow.
XTake cover : off the opening.XScrew in and tighten the towing eye

XPlace the towing eye in the vehicle tool kit.
Towing the vehicle with the rear axle
raised
When having your vehicle towed with the rear
axle raised, observe the important safety
notes (Y page 298).
! The ignition must be switched off if you
are towing the vehicle with the rear axle
raised. Intervention by ESP® could
otherwise damage the brake system.
XSwitch on the hazard warning flashers
(Y page 124).
XTurn the SmartKey to position 0 in the
ignition lock and remove the SmartKey.
XWhen leaving the vehicle, take the
SmartKey or the KEYLESS-GO key with you.
Towing the vehicle with both axles on
the ground
When having your vehicle towed, observe the
important safety notes (Y page 298).
GWarning
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
XTurn the SmartKey to position 2 in the
ignition lock.
XWhen the vehicle is stationary, depress the
brake pedal and hold it down.
XRelease the brake pedal.XRelease the parking brake.XSwitch on the hazard warning flashers
(Y page 124).
iWhen towing with the hazard warning
flashers switched on, use the combination
switch as usual to signal in which direction
you are changing. In this case, only the
indicator lamps for the direction of travel
flash. When you reset the combination
switch, the hazard warning flashers start
flashing again.
Transporting the vehicle
The towing eye can be used to pull the vehicle
onto a trailer or transporter for transporting
purposes.

the vehicle, all passengers, cargo and trailer
load/noseweight (if applicable) must not
exceed the permissible gross vehicle weight.Gross axle weight rating: the maximum
permissible load that can be carried by one
axle (front or rear axle).
To ensure that your vehicle does not exceed
