ESP
®
(Electronic Stability Program)
Important safety notes i
See the "Important safety notes" section
(Y page 72).
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle .Ifnecessary, 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 a skid.
ESP ®
cannot reduce the risk of an acciden tif
you drive too fast. ESP ®
cannot override the
laws of physics.
! Switch the ignition off when:
R the parking brake is bein gtested 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.
! Do not tow vehicles with 4MATIC with the
front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly. ETS/4ETS (Electronic Traction System) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
. G
WARNING
Traction control cannot reduce the risk of an
acciden tifyou drive too fast. Traction control
cannot override the laws of physics.
Deactivating/activating ESP ®
(except
AMG vehicles) You cannot activate and deactivate ESP
®
on
vehicles with a 4-button multifunction steer-
ing wheel.
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 a stop. The engine starts auto-
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.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
WARNING
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle Driving safety systems

Position of the steering wheel when the
EASY-ENTRY/EXIT featurei
s activeThe steering wheel tilts upwards if you:
R
remove the key from the ignition lock
R open the driver's door and KEYLESS-GO is
in position 1
R open the driver's door and the key is in
position 0or 1in the ignition lock
i The steering wheel only moves upwards if
it has not already reached the upper end
stop.
If you insert the key into the ignition lock with
the driver's door closed, the steering wheel is
automatically moved to the previously set
position.
Position of the steering wheel for driv-
ing The steering wheel is moved to the previously
set position if:
R
the driver's door is closed
R you insert the key into the ignition lock
or
R you press the Start/Stop button once on
vehicles with KEYLESS-GO.
If you close the driver's door with the key
inserted into the ignition lock, the steering
wheel is automatically moved to the previ-
ously set position.
The last position of the steering wheel is
stored after each manual setting or when you
store the setting with the memory function
(Y page 115).
Crash-responsive EASY-EXIT feature If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering column
will move upwards when the driver's door is
opened. This occurs irrespective of the posi-
tion of the key in the ignition lock. This makes
it easier to exit the vehicle and rescue the
occupants. The crash-responsive EASY-EXIT feature is
only operational if the EASY-EXIT/ENTRY fea-
ture is activated in the on-board computer. Mirrors

WARNING
The exterior mirrors reduce the size of the
image. Objects are actually closer than they
appear. You could misjudge the distance from
vehicles driving behind and cause an acci-
dent, e.g. when changin glane. For this rea-
son, make sure of the actual distance from the
vehicle driving behind by glancing ove ryour
shoulder.
The convex exterior mirrors provide a larger
field of vision.
The exterior mirrors are automatically heated
if the rear window heating is switched on and

wheel
Preparing the vehicle G
WARNING
The wheel and tyre size of the emergency
spare wheel/spare wheel may diffe rto that 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
emergency spare wheel/spare wheel that dif-
fers in size.
Only use an emergency spare wheel/spare
wheel of a differing size briefly and do not
switch off ESP ®

X
Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated
(: toA ). The tightening torque must be
130 Nm. G
WARNING
Have the tightening torque checked immedi-
ately after a wheel is changed. The wheels
could work loose if they are not tightened to
a torque of 130 Nm.
X Turn the jack back to its initial position and
store it together with the rest of the tyre-
change tool kit in the boot/luggage com-
partment.
X Transport the faulty wheel in the boot/lug-
gage compartment.
or
X Depending on the size of the wheel, you
may also be able to secure the faulty wheel
in the spare wheel well. In this case, you
will have to remove the stowage well casing
from the spare wheel well and stow it
securely in the boot/luggage compart-
ment.
i When you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressure loss warning system or the tyre
pressure monitor cannot function reliably.
Only restart the tyre pressure loss warning
system/tyre pressure monitor when the
defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: all fit-
ted wheels must be equipped with func- tioning sensors. The defective wheel
should no longer be in the vehicle. 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 activated tyre pressure loss
warning system or with the tyre pressure
monitor.
The maximum permissible distance which
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 distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure loss warning
appears in the multifunction display.
You must not exceed a maximum 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 a large
exten tonthe loads placed on the vehicle. It
can be shorter due to high speeds, a heavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you drive carefully and conserva-
tively. Flat tyre
345Breakdown assistance
Z

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 a quali-
fied specialis tworkshop 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-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 a qualified 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 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
properties, e.g. winter tyres. A TIREFIT kit
can be obtained from a Mercedes-Benz
Service Centre. Battery
Important safety notes
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz. Consult a Mercedes-Benz Service Centre if
you wish to leave your vehicle parked up for
a long period of time. G
WARNING
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the battery.
Avoid creating sparks.
Battery acid is caustic.
Avoid contact with the skin,
eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a face
mask.
Immediately rinse acid
splashes off with clean
water. Consult a doctor if
necessary.
Wear eye protection.
Keep children away.
Observe this Owner's Man-
ual.
