free of damage and is roadworthy. Notes on parking up the vehicle
If you leave the vehicle parked up for longer than
six w

eeks, it may suMer damage through disuse.
The 12 V battery may also be impaired or dam-
aged by heavy discharging.
Vehicles with automatic transmission: do not dis-
connect the 12 V battery even if the vehicle is les
idle for a lengthy period.
% Further information can be obtained at a

per
iod out of use) Standby mode function
% This function is not available for all models. If standby mode is activated, energy loss will be
minimised dur
ing extended periods of non-opera-
tion.
Standby mode is characterised by the following:
= The starter battery is preserved.
= The maximum non-operational time appears in
the media display.
= The connection to online services is interrup-
ted.
= The ATA (anti-thes alarm system) is not availa-
ble.
= The interior protection and tow-away protec-
tion functions are not available.
= The function for detecting collisions on a
parked vehicle is not available.
If the following conditions are fulNlled, standby
mode can be activated or deactivated using the
multimedia system:
= The vehicle is switched on.
= The vehicle has not been started.
Exceeding the vehicle's displayed non-operational
time may cause inconvenience; i.e. it cannot be guaranteed that the starter battery will reliably
s tart the vehicle.
Charge the starter battery in the following situa-
tions:
= The vehicle's non-operational time must be
extended.
= The Battery charge insufficient for standby
mode message appears in the media display.
% Standby mode is automatically deactivated
when t
he vehicle is switched on.

Driving and driving safety systems
Driving systems and your responsibility
Your vehicle is equipped with driving systems
whic h assist you in driving, parking and manoeu-
vring the vehicle. The driving systems are only
aids. They are not a substitute for you paying
attention to your surroundings and do not relieve
you of your responsibility pertaining to road traPc
law. The driver is always responsible for maintain-
ing a safe distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for staying
in lane. Pay attention to the traPc conditions at
all times and intervene when necessary. Be aware
of the limitations regarding the safe use of these
systems.
Driving systems can neither reduce the risk of
accident if you fail to adapt your driving style nor
override the laws of physics. They cannot always
take into account road, weather or traPc condi-
tions. Information on vehicle sensors and cameras
Some driving and driving safety systems use cam-
er
as as well as radar or ultrasonic sensors to
monitor the area in front of, behind or next to the
vehicle. 1

2 Cameras in the outside mirrors
3 Front radar 4

WARNING Risk of accident due t
o restric-
ted detection performance of vehicle sen-
sors and cameras
If the area around vehicle sensors or cameras
is co
vered, damaged or dirty, certain driving
and safety systems cannot function correctly.
There is a risk of an accident. 
Keep the area around vehicle sensors or
camer

as clear of any obstructions and
clean. 
Have damage to the bumper, radiator
g

rille or stone chipping in the area of the
front and rear windows repaired at a
qualiNed specialist workshop. Particularly, keep the areas around the sensors
and camer
as free of dirt, ice or slush
(  page 348). The sensors and cameras must Driving and parking
223

not be covered and the detection ranges around
t hem must be kept free. Do not attach additional
licence plate brackets, advertisements, stickers,
foils or foils to protect against stone chippings in
the detection range of the sensors and cameras.
Make sure that there are no overhanging loads
protruding into the detection range.
If there is damage to a bumper or the radiator
grille, or aser an impact, have the function of the
sensors checked at a qualiNed specialist work-
shop. Have damage or stone chipping in the area
of the cameras on the front and rear windows
repaired at a qualiNed specialist workshop. Overview of driving systems and driving safety

Functions of ABS
The Anti-lock Brake System (ABS) regulates the
br
ake pressure in critical driving situations:
= During braking, for instance, at maximum full-
stop braking or if there is insuPcient tyre trac-
tion, the wheels are prevented from locking.
= Vehicle steerability while braking is ensured.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road con-
ditions and can serve as a reminder to take extra
care while driving.
System limits
= ABS is active from speeds of approx. 5 km/h.
= ABS may be impaired or may not function if a
malfunction has occurred and the yellow %
ABS warning lamp lights up continuously aser
the vehicle is started. Function of BAS
&
WARNING Risk of an accident caused b y a
malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance
in an emer
gency braking situation is
increased. 
Depress the brake pedal with full force in
emer

gency braking situations. ABS pre-
vents the wheels from locking. The Brake Assist System (BAS) supports your
emer
gency braking situation with additional brake
force.
If you depress the brake pedal quickly, BAS is
activated:
= BAS automatically boosts the brake pressure.
= BAS can shorten the braking distance.
= ABS prevents the wheels from locking.
The brakes will function as usual once you release
the brake pedal. BAS is deactivated. Functions of ESP

If the vehicle deviates from the direction desired
b y the driver, ESP n
can stabilise the vehicle by
intervening in the following ways:
= One or more wheels are braked.

situation.

WARNING Risk of accident in poor r
oad
and weather conditions
In poor road and weather conditions, the
tr
ailer stabilisation cannot prevent lurching of
the vehicle/trailer combination. Trailers with a
high centre of gravity may tip over before
ESP n
detects this. 
Always adapt your driving style to suit
t

he current road and weather conditions. When driving with a trailer, ESP
n
can s
tabilise
your vehicle if the trailer begins to swerve from
side to side:
= ESP n
trailer stabilisation is active above
speeds of 65 km/h.
= Slight swerving is reduced by means of a tar-
geted, individual brake application on one
side. =
In t
he event of severe swerving, the operating
energy output is also reduced and all wheels
are braked.

Function of STEER CONTROL
STEER CONTROL assists you by transmitting a
no
ticeable steering force to the steering wheel in
the direction required for vehicle stabilisation.
This steering recommendation is given in the fol-
lowing situations:
= both right wheels or both les wheels are on a
wet or slippery road surface when you brake
= the vehicle starts to skid
System limits
STEER CONTROL may be impaired or may not
function in the following situations:
= ESP n
is deactivated.
= ESP n
is malfunctioning.
= The steering is malfunctioning.
If ESP n
is malfunctioning, you will be assisted fur-
ther by the electric power steering. HOLD function
HOLD function
The HOLD function holds t
he vehicle at a stand-
still without requiring you to depress the brake
pedal, e.g. while waiting in traPc.
The HOLD function is only an aid. The responsibil-
ity for the vehicle safely standing still remains with
the driver.
System limits
The HOLD function is only intended to provide
assistance when driving and is not a suPcient
means of safeguarding the vehicle against rolling
away when stationary.
= The incline must not be greater than 30%. Activating/deactivating the HOLD function &
WARNING Risk of an accident due t o the
HOLD function being active when you
leave the vehicle
If the vehicle is only braked with the HOLD
function it could, in t
he following situations,
roll away:
= If there is a malfunction in the system or in
the power supply.
= If the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant. 
Always secure the vehicle against rolling
a
way before you leave it. Requirements:
= The v

ehicle is stationary.
= The driver's door is closed or the seat belt on
the driver's side is fastened.
= The vehicle has been started or has been
automatically switched oM by the ECO start/
stop function. 228
