pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality could affect your vehi-
cle's operating safety.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
High-performance and ceramic brake
system (Mercedes-AMG vehicles)
The high-performance brake system is only
available on Mercedes-AMG vehicles.
The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:
RSpeed
RBraking force
RAmbient conditions, e.g. temperature and
humidity
The wear of individual components of the
brake system, such as the brake pads/linings or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all circum-
stances. An aggressive driving style will lead
to high wear. You can obtain more informa-
tion on this from a qualified specialist work-
shop.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal. Keep this in mind, and adapt
your driving and braking accordingly during
this break-in period.
Excessive heavy braking results in corre-
spondingly high brake wear. Observe the
brake system warning lamp in the instrument
cluster and note any brake status messages in the multifunction display. Especially for
high performance driving, it is important to
maintain and have the brake system checked
regularly.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if:
Ryou drive at low speeds.
Rthe tires have adequate tread depth.
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
Rlower your speed.
Ravoid ruts.
Ravoid sudden steering movements.
Rbrake carefully.
Driving on flooded roads
!Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic compo-
nents in the engine or the automatic trans-
mission. Water can also be drawn in by the
engine's air suction nozzles and this can
cause engine damage.
Winter driving
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.

Cruise Control
Genera l notes
Cruisecontrol maintains aconstan troad
spee dfor you. It brakes automatically in order
to avoi dexceedin gth eset speed. On lon gand
steep downhill gradients ,especially if th e
vehicl eis laden ,you mus tselect alower gear
in goo dtime. By doin gso, you will mak euse of
th ebrakin geffec tof th eengine. This relieves
th eload on th ebrak esystem and prevents
th ebrakes from overheating and wearing to o
quickly.
Use cruise control only if road and traffic con-
dition smak eit appropriat eto maintai n a

damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop.
XRemove dirt immediately, where possible,
while avoiding rubbing too hard.
XSoak insect remains with insect remover
and rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse
off the treated areas afterwards.
XRemove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
If water no longer forms "beads" on the paint surface, use the paint care products recom-
mended and approved by Mercedes-Benz.
This is the case approximately every three to
five months, depending on the climate con-
ditions and the care product used.
If dirt has penetrated the paint surface or if
the paint has become dull, the paint cleaner
recommended and approved by Mercedes-
Benz should be used.
Do not use these care products in the sun or
on the hood while the hood is hot.
XUse a suitable touch-up stick, e.g. MB
Touch-Up Stick, to repair slight damage to
the paintwork quickly and provisionally.

Preparing the vehicle
Your vehicle may be equipped with:
Rtires with run-flat characteristics
(MOExtended tires) (
Ypage 291)
Vehicle preparation is not necessary on
vehicles with MOExtended tires
Ran emergency spare wheel (Ypage 339)
Vehicles equipped with MOExtended tires 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 mount tires that do not feature run-flat
properties, e.g. winter tires. A TIREFIT kit may
be obtained from a qualified specialist work-
shop.
Information on changing/mounting a wheel
(
Ypage 330).
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 160).
XIf possible, bring the front wheels into the
straight-ahead position.
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 140).
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.
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 324).
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If a pressure loss warning message
appears in the multifunction display:
Robserve the instructions in the display mes-
sages (
Ypage 234).
Rcheck the tire for damage.
Rif driving on, observe the following notes.
The driving distance possible in run-flat mode
is approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.
Flat tire291
Breakdown assistance

In addition to the vehicle load, the driving dis-
tance possible depends upon:
Rvehicle speed
Rroad condition
Routside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving condi-
tions or maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure loss warning appears in the multifunction dis-
play.
You must not exceed a maximum speed of
50 mph (80 km/h).
iWhen replacing one or all tires, please
observe the following specifications for
your vehicle's tires:
Rsize
Rthe type and
Rthe "MOExtended" mark
If a tire has gone flat and cannot be
replaced with a MOExtended tire, a stand-
ard tire may be used as a temporary meas-
ure. Make sure that you use the proper size
and type (summer or winter tire).
iVehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit is available, for example, from a qualified specialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, potholes,
off-road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.
Ryou see smoke and smell rubber.
RESP®is intervening constantly.
Rthere are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
defective tire must be replaced in every case.
TIREFIT kit
Important safety notes
TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up to
0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside tem-
peratures down to Ò4 ‡ (Ò20 †).
GWARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tire properly:
Rthere are cuts or punctures in the tire larger
than those mentioned above.
Rthe wheel rim is damaged.
Ryou have driven at very low tire pressures or on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a qualified
specialist workshop.
GWARNING
The tire sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tire sealant away
from children. There is a risk of injury.

that it must be replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same
type and make.
Exception: it is permissible to install a dif-
ferent type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(
Ypage 291).
ROnly mount tires of the correct size onto
the wheels.
RBreak in new tires at moderate speeds for
the first 60 miles (100 km). They only reach
their full performance after this distance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
RReplace the tires after six years at the lat-
est, regardless of wear.
MOExtended tires (tires with run-flat
properties)
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.
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure monitor and on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tires with
a flat tire (
Ypage 291).
iVehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires. A TIREFIT kit can be obtained from a quali-
fied specialist workshop.
Winter operation
General notes
Have your vehicle winter-proofed at a quali-
fied specialist workshop at the onset of win-
ter.
Observe the notes in the "Changing a wheel"
section (
Ypage 330).
Driving with summer tires
At temperatures below 45
‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehi-
cle to M+S tires. Using summer tires at very
cold temperatures could cause cracks to
form, thereby damaging the tires perma-
nently. Mercedes-Benz cannot accept
responsibility for this type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with a tire tread depth of less than
ã in (4 mm) are not suitable for use in winter
and do not provide sufficient traction. There is
a risk of an accident.
M+S tires with a tread depth of less than ãin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use win-
ter tires or all-season tires. Both types of tire
are identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking pro-
