The lane departure warning systemobserves the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● no operation of turn lights
● no brake pedal operation
● no active acceleration
If the driver is active, no warning will
be issued.

164Driving and operatingActivation
The lane departure warning system isactivated by pressing ½. The system
is switched on when the LED in the
button is not illuminated.
The system is only operable at
vehicle speeds above 60 km/h and if
lane markings are available.
When the system recognises an
unintended lane change, the control
indicator ) flashes yellow.
Simultaneously a chime sound is
activated.
Deactivation
The system is deactivated by
pressing ½, the LED in the button
illuminates.
At speeds below 60 km/h the system
is inoperable.
Fault

the instrument cluster, accompanied
by a display message. Seek the
assistance of a workshop.
The system cannot operate when no
lane marking is detected.
System limitations
The system may not operate properly when:
● vehicle speed is below 60 km/h● driving on winding or hilly roads
● driving in the dark
● weather limits visibility, such as fog, rain, or snow
● the camera is blocked by snow, ice, slush, mud, dirt, windscreen
damage or affected by foreign
items, e.g. stickers
● the sun is shining directly into the
camera lens
● close vehicles ahead
● banked roads
● road edges
● roads with poor lane markings
● sudden lighting changes
Driver alert9 Warning
The system cannot replace the
need for vigilance on the part of
the driver. Taking a break is
recommended as soon as feeling tired or at least every two hours.
Do not take the steering wheel
when feeling tired.

172Driving and operatingInserting the coupling ball bar
Insert the tensioned coupling ball bar
in the opening and push firmly
upwards until it audibly engages.
The rotary handle snaps back into its
original position resting against the
coupling ball bar without a gap.
9 Warning
Do not touch rotary handle during
insertion.
Lock the coupling ball bar by turning
the key to position c. Remove the key
and close the protective flap.
Eye for break-away stopping cable
Attach breakaway stopping cable to
eye.
Checking the correct installation of
the coupling ball bar
● Green marking on rotary knob must point towards green
marking on coupling ball bar.
● There must be no gap between the rotary handle and the
coupling ball bar.
● The coupling ball bar must be firmly engaged in the opening.
● The coupling ball bar must be locked and the key removed.
9Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Dismounting the coupling ball bar
Open the protective flap and turn the
key to position c to unlock the
coupling ball bar.
Pull out rotary handle and turn
clockwise as far as it will go. Pull out coupling ball bar downwards.
Insert sealing plug in opening.

176Vehicle careVehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
9 Danger
The ignition system uses
extremely high voltage. Do not
touch.
Bonnet
Opening
Open the driver's door.
Pull the lever and return it to its
original position.
Move the safety catch sideways to the
left vehicle side and open the bonnet.
The bonnet is held open
automatically.
Closing
Lower the bonnet and let it fall into the latch from a low height (20-25 cm).
Check that the bonnet is engaged.
Caution
Do not press the bonnet into the
latch to avoid dents.

178Vehicle careCaution
Overfilled engine oil must be
drained or suctioned out. If the oil exceeds the maximum level, do
not start the vehicle and contact a
workshop.
Capacities 3 229.
Fit the cap on straight and tighten it.
Engine coolant The factory filled coolant provides
freeze protection down to approx.
-37 °C.
Caution
Only use approved antifreeze.
Coolant and antifreeze 3 219.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
MIN mark. Top up if the level is low.
9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up, use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.

Vehicle care179Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 219.
Brakes In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid
9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.

Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.

Replacing the vehicle battery Note
Any deviation from the instructions
given in this section may lead to temporary deactivation or
disturbance of the stop-start system.
Page 182 of 253

180Vehicle careWhen the vehicle battery is beingreplaced, ensure that there are no
open ventilation holes in the vicinity of
the positive terminal. If a ventilation
hole is open in this area, it must be
closed off with a dummy cap, and the ventilation in the vicinity of the
negative terminal must be opened.
Ensure that the vehicle battery is
always replaced by the same type of
battery.
The vehicle battery has to be
replaced by a workshop.
Stop-start system 3 126.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may
be damaged.
Jump starting 3 207.
Discharge protection
Battery voltage
When the vehicle battery voltage is
running low, a warning message will
appear in the Driver Information
Centre.
When the vehicle is being driven, the
load reduction function temporarily
deactivates certain functions, e.g. the
heated rear window.
The deactivated functions are
reactivated automatically as soon as
conditions permit.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Power outlet
The power outlets are deactivated in
the event of low vehicle battery
voltage.Warning label
Meaning of symbols:
● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
