or BAS PLUS, the brake lamps flash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from aspeed of more
than 70 km/htoa standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automaticallyify ou travel
faster than 10 km/h .You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 117).ESP

Important safety notes i
See the "Important safety notes" section
(Y page 61).
If ESP ®
detect sthat the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster. G
WARNING
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise, the vehicle could go into askid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics. !
Switch the ignition off when:
R the parking brake is being tested using a
dynamometer
R the vehicle is being towed with the front/
rear axle raised
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS (Electronic Traction Support) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
viduall yifthey spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side.
Traction control remains active if you deacti-
vate ESP ®
. G
WARNING
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
Deactivating/activating ESP ® i
Observe the "Important safety notes" sec-
tion (Y page 61).
ESP ®
is activated automatically when the
engine is started.
i Vehicles with ECO start/stop function:
the ECO start/stop function switches the
engine off automatically when the vehicle
comes to astop. The engine startsa uto-
matically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. Example: if ESP ®
was
deactivated before the engine was
switched off, ESP ®
remains deactivated
when the engine is switched on again. 64

Preparing the vehicle G
WARNING
The wheel and tyre size of the emergency
spare wheel/spare wheel may diffe rtothat of
the damaged wheel. When using an emer-
gency spare wheel/spare wheel the handling
characteristics of the vehicle may change.
Adapt your style of driving accordingly.
Never operate the vehicle with more than one
emergenc yspare wheel/spare wheel that dif-
fers in size.
Only use an emergenc yspare wheel/spare
wheel of adiffering size briefly and do not
switch off ESP ®
.
When using an emergenc yspare wheel you
must not exceed the maximum speed of
80 km/h. G
WARNING
Have the emergenc yspare wheel/spare
wheel replaced with anew wheel as soon as
possible at aqualified specialist workshop
which has the necessary specialist knowledge
and tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop. i
Vehicles without an emergenc yspare
wheel/spare wheel are not equipped with
wheel-changing tools at the factory. For
more information on which tools are
required to perform awheel change on your
vehicle, e.g. wheel chock,w heel wrench or
centring pin, consult aMercedes-Benz
Servic eCentre.
X Prepare the vehicle as described
(Y page 296).
X Ifat railer is coupled to the vehicle, uncou-
ple it.
X Remove the following items (depending on
the vehicle's equipment) from the stowage
well under the boot floor:
R
the emergenc yspare wheel
R the vehicle tool kit
R the folding wheel chock
R the jack
X Secure the vehicle to prevent it from rolling
away.
Securing the vehicle to prevent it from
rolling away If your vehicle is equipped with
awheel chock,
it can be found in the vehicle tool kit
(Y page 295).
The folding wheel chock is an additional
securing measure to prevent the vehicle from
rolling away,f or example when changing a
wheel. Flat tyre

warning system cannot function reliably.
Only restart th
etyrep ressure loss warning
system when the defective whee lhas been
replaced with anew wheel. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the
vehicl eeven when one or more tyres lose all
air pressure.
MOExtended tyres may only be usedinc on-
junction with the activated tyre pressure loss
warning system or with the tyre pressure
monitor.
The maximu mpermissible distanc ewhich
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distanc ewhich
can be driven in run-flat mode is counted from
the momen tthe tyre pressure loss warning
appears in the multifunction display.
You must not exceed amaximum speed of
80 km/h. G
WARNING
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to alarge
extentont he loads placed on the vehicle. It
can be shorter due to high speeds, aheavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc., or further if you drive carefully and conserva-
tively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in run-flat mode, you must have
the wheel(s) checked for damage at aquali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
i When replacing one or all tyres, make
sure that you only use tyres marked
MOExtended and of the specified size for
the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFI Tkit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with aTIREFI Tkit
if you fit tyres that do not feature run-flat
properties, e.g. winter tyres. ATIREFI Tkit
can be obtained from aMercedes-Benz
Service Centre. Battery
Important safety notes
In order for the batter ytoachieve the maxi-
mum possible service life, it must alway sbe
sufficiently charged.
Have the batter ycharge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period. Battery

Tyre tread
G
WARNING
Bea rinm indt hat:
R tyr eg ripd ecreases rapidl yonwetroads
when the tread depth is less than 3mm.
Thus ,you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4mmorless as they no lon-
ger provide adequate grip.
R the tread on atyre may not wear evenly.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the fron twheels to full lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Notes on selecting, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fittingn ew tyres, run them in at mod-
erate speeds for the first 100 km, as they
only reach their full performance after this
distance.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the emergency spare wheel/spare wheel. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics )allow you to continue driving the vehicle even when one or more tyres lose all
air pressure.
MOExtended tyres may only be used in con-
junction with the tyre pressure loss warning
system or with the tyre pressure monitor and
on wheels specifically tested by Mercedes-
Benz.
i
Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with the TIREFIT
kit if you fit tyres that do not feature run-
flat properties, e.g. winter tyres. ATIREFIT
kit can be obtained from aMercedes-Benz
Service Centre.
You will find notes on driving with aflat tyre
in the "Breakdown assistance" section
(Y page 305). Winter operation
Please bear the following in mind
At the onset of winter ,have your vehicle win-
terproofed at aqualified specialist workshop,
e.g. at aMercedes-BenzS ervice Centre.
Observe the notes in the "Changing awheel"
section (Y page 323). Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticit yand therefore traction and
brakin gpower; change the tyres on your vehi-
cle to M+S tyres .Using summer tyres at very
cold temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benzc annot accept responsibility
for this type of damage. M+S tyres
At temperatures below +7 †, use winter tyres
or all-season tyres. Bot htype soft yrea re

WARNING
Tyre pressure that is either too high or too low
has anegative effect on the vehicle's driving
safety, which could lead you to cause an acci-
dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correc tthe pressure as nec-
essary.
To test tyre pressure, use asuitable pressure
gauge. The outer appearance of atyre does
not permit any reliablec onclusion about the

WARNING
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve Tyrep
