Important safety notes
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants.
There is a risk of injury, particularly in the
event of sudden braking or a sudden change
in direction.
RAlways stow objects so that they cannot be
thrown around in such situations.
RAlways make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
RClose the lockable stowage spaces while
driving.
RStow and secure objects that are heavy,
hard, pointy, sharp-edged, fragile or too
large in the cargo compartment.
Observe the loading guidelines (Ypage 340).

Rsolvents
Rcleaning 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
GWARNING
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.
!Before driving into an automatic car wash,
make sure that it is suitable for the dimen-
sions of the vehicle. In particular, make
sure that:
Rthere is enough ground clearance
between the vehicle underbody and the
guide rails of the automatic car wash.
Rthe clearance width of the automatic car
wash is sufficient, particularly the width
of the guide rails.
Ryou enter the automatic car wash
straight and in the center of the guide
rails in order to avoid damaging the tires or wheel rims.
Fold in the exterior mirrors before the vehi-
cle is washed. The exterior mirrors could
otherwise be damaged.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations.
To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func-
tion in the following or other similar situa-
tions:
Rwhen towing the vehicle
Rin 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.
!Make sure that:
Rthe side windows and the sliding sunroof are fully closed.
Rthe ventilation/heating is switched off
(the OFF button has been pressed).
Rthe windshield wiper switch is in position
0.
Otherwise, the vehicle might be damaged.
!In car washes with a towing mechanism,
make sure that the automatic transmission
is in transmission position N, otherwise the
vehicle could be damaged.

Useful information
i
This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops (
Ypage 29).
Where will I find...?
Vehicle tool kit
General notes
The vehicle tool kit can be found in the stow- age well under the cargo compartment floor.
iApart from certain country-specific varia-
tions, the vehicles are not equipped with a
tire-change tool kit. Some tools for chang-
ing a wheel are specific to the vehicle. For
more information on which tools are
required to perform a wheel change on your
vehicle, consult a qualified specialist work-
shop.
Tools required for changing a wheel may
include, for example:
RJack
RWheel chock
RLug wrench
RRatchet wrench
RAlignment bolt
Vehicles with a TIREFIT kit
:Lug wrench
;Towing eye
=Ratchet wrench

Flat tire
Preparing the vehicle
Your vehicle may be equipped with:
RMOExtended tires (tires with run-flat prop-
erties)
Vehicle preparation is not necessary on
vehicles with MOExtended tires
Ra TIREFIT kit
Ran emergency spare wheel (only for certaincountries)
Information on changing/mounting a wheel
(
Ypage 427).
XStop the vehicle on solid, non-slippery and
level ground, as far away as possible from
traffic.
XSwitch on the hazard warning lamps.
XSecure the vehicle against rolling away
(
Ypage 189).
XIf possible, bring the front wheels into the
straight-ahead position.
XVehicles with the AIRMATIC package:
make sure that highway level is selected
(
Ypage 219).
XVehicles with the ON&OFFROAD pack-
age: make sure that highway level is selec-
ted (
Ypage 213).
XSwitch off the engine.
XVehicles without KEYLESS-GO: remove
the SmartKey from the ignition lock.
XVehicles with 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.
XVehicles with KEYLESS-GO: remove the
Start/Stop button from the ignition lock
(
Ypage 165).
XMake sure that the passengers are not
endangered as they do so. Make sure that
no one is near the danger area while a
wheel is being changed. Anyone who is not
directly assisting in the wheel change
should, for example, stand behind the bar-
rier.
XGet out of the vehicle. Pay attention to traf-
fic conditions when doing so.
XClose the driver's door.
XUnload heavy luggage.
iOnly operate the tire inflation compressor
using a 12 V socket, even if the ignition is
turned off (
Ypage 353).
An emergency cut-out ensures that the on-
board voltage does not drop too low. If the on-board voltage is too low, the power to
the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine.
MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(
Ypage 421).
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
