General notes G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or if there is a malfunc-
tion in the system, it may not be possible to
apply the released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it from
rolling away.
X Vehicles with automatic transmission:
shift the automatic transmission to posi-
tion P.
X Vehicles with manual transmission:
engage first gear.
It may not be possible to release an applied
parking brake if the on-board voltage is low or if there is a malfunction in the system. Con-
tact a qualified specialist workshop.
The electric parking brake carries out a func-
tion check at regular intervals when the 182

Cup holders
Important safety notes G
WARNING
The cup holder cannot secure a drinks con-
tainer in place during a journey. If you use a
cup holder during a journey, the drinks con-
tainer could be flung around and liquid could
be spilt. Vehicle occupants could come into
contact with the liquid and, in particular, be
scalded by hot liquid. You could be distracted
from the traffic situation and lose control of
the vehicle. There is a risk of an accident and
injury.
Only use the cup holder when the vehicle is
stationary. Only place containers of a suitable size in the cup holder. Seal the container, in
particular when it contains hot liquid. G
WARNING
If you do not correctly store objects in the
vehicle interior, they can slip or be flung
around, thus striking vehicle occupants.
There is a risk of injury, especially when brak- ing or abruptly changing directions.
R Always store objects so that they cannot be
flung around in these or in similar situa-
tions.
R Always make sure that objects do not pro-
trude from stowage compartments, lug-
gage nets or stowage nets.
R Close lockable stowage compartments
while driving.
R Stow and secure objects that are heavy,
hard, pointy, sharp-edged, fragile or too
large in the luggage compartment.
! Only use the cup holders for containers of
the right size and which have lids. The
drinks could otherwise spill.
Observe the loading guidelines (Y page 298).The stowage compartments in the doors pro-
vide space for bottles:
R front: capacity up to 1.5 l
R rear: capacity up to 0.5 l
Cup holders in the front centre console The cup holder and the rubber mat under-
neath can be removed for cleaning. Clean

Your vehicle may be equipped with: R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 334)
Vehicle preparation is not necessary on
vehicles with MOExtended tyres.
R a TIREFIT kit (Y page 333)
R an emergency spare wheel (only for certain
countries) (Y page 380)

X Stop the vehicle as far away as possible
from traffic on solid, non-slippery and level
ground.
X Switch on the hazard warning lamps.
X Secure the vehicle against rolling away
(Y page 181).
X If possible, bring the front wheels into the
straight-ahead position.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the key from the ignition lock.
X Vehicles with KEYLESS-GO start-func-
tion or KEYLESS-GO: open the driver's

X Vehicles with KEYLESS-GO start func-
tion or KEYLESS-GO: remove the Start/
Stop button from the ignition lock
(Y page 159).
X All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area while a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Get out of the vehicle. Pay attention to traf-
fic conditions when doing so. X
Close the driver's door.
X Place the warning triangle at a suitable dis-
tance (Y page 332). Observe legal require-
ments.
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It
is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit can be obtained from a qualified spe-
cialist workshop. MOExtended tyres (tyres with run-flat
characteristics)
General notes With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres. The affected
tyre must not show any clearly visible dam-
age.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the
tyre wall. You will find this marking next to the
tyre size designation, the load-bearing capa-
city and the speed index.
MOExtended tyres may only be used in con-
junction with an activated tyre pressure loss
warning system or tyre pressure monitor.
If a pressure loss warning message
appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 276)
R check the tyre for damage
R if driving on, observe the following notes
The driving distance possible in run-flat mode is approximately 80 km when the vehicle is
partially laden and approximately 30 km
when the vehicle is fully laden. 334

! When COLLISION PREVENTION ASSIST
PLUS, DISTRONIC PLUS or the HOLD func- tion is activated, the vehicle brakes auto-
matically in certain situations. To avoid
damage to the vehicle, deactivate these
systems in the following or similar situa-
tions:
R when towing away
R in a car wash
! Make sure that the electric parking brake
is released. If the electric parking brake is
faulty, visit a qualified specialist workshop.
! Only secure the tow cable or tow bar to
the towing eyes or, if available, to the trailer
tow hitch. You could otherwise damage the
vehicle.
! Observe the following points when towing
with a tow rope:
R Secure the tow rope on the same side on
both vehicles.
R Make sure that the tow rope is not longer
than legally permitted. Mark the tow rope
in the middle, e.g. with a white cloth
(30 x 30 cm). This will make other road
users aware that a vehicle is being
towed.
R Only secure the tow cable to the towing
eyes or, if available, to the trailer tow
hitch.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain a
distance 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. !
Pull away smoothly when towing away or
tow-starting a vehicle. If the tractive power
is too high, the vehicles could be damaged.
! You may tow the vehicle for a maximum of
50km. A towing speed of 50 km/h must not be exceeded.
For towing distances over 50 km, the frontaxle or the entire vehicle must be raised
and transported.
! To tow vehicles with KEYLESS-GO, use
the key instead of the Start/Stop button.
The automatic transmission may otherwise switch to position Pwhen you open the
driver's or front-passenger door which
could damage the transmission.
! Vehicles with automatic transmission
must not be tow-started. The transmission
may otherwise be damaged.
Observe the legal requirements for the rele-
vant countries when towing and tow-starting.
It is better to have the vehicle transported
than to have it towed.
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.
Vehicles with automatic transmission:
when towing a vehicle, the transmission must be in position N.
The battery must be connected and charged.
Otherwise, you:
