The system cannot operate when no
lane marking is detected.
System limitationsThe system may not operate properly
when:
● vehicle speed is below 37 mph
● 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 alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to the lane markings.
The system includes a driving time alert combined with driver drowsiness
detection.9 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 2 hours. Do
not take the steering wheel when
feeling tired.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 123.
The state of the system stays in
memory when the ignition is switched off.
Driving time alert
The driver gets notified by a pop-up reminder symbol Y in the Driver
Information Centre simultaneously with an acoustic alert if the driver has
not taken a break after 2 hours of
driving at a speed above 40 mph. The alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.

Driving and operating205After the automatic cut-off, the tank
can be topped up by operating the
pump nozzle a maximum of two more
times.Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and allow it to engage.
Fuel filler cap
Only use genuine fuel filler caps.
Diesel-engined vehicles have special fuel filler caps.
Trailer hitch
General information
Only use towing equipment that has
been approved for the vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Driving characteristics and towing tips
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements.
During trailer towing do not exceed a
speed of 50 mph. A maximum speed
of 60 mph is only appropriate if an
oscillation damper is used and the
permissible gross trailer weight does
not exceed the vehicle's curb weight.For trailers with low driving stability
and caravan trailers, the use of an
oscillation damper is strongly
recommended.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
If the outside temperature exceeds
37 °C, reduce the load on the trailer
to protect the engine of the vehicle.
At high outside temperatures it is
recommended to leave the engine
running for one or two minutes after
having stopped the vehicle in order to
faciliate cooling.
Adjust tyre pressure to the value
specified for full load 3 271.
Towing a trailer increases the braking
distance of the vehicle. To limit the
heating of the brakes, it is
recommended to use the braking
effect of the engine.

Driving and operating209Type C
1. Remove the safety splint.
2.Pull the lever and open the towing
ring.
3. Swivel the connecting socket downwards.
4. Attach the trailer, close the towing
ring and fix the splint.
5. Connect the trailer plug to the socket and attach the breakaway
stopping cable to the eye on the
carrier.
Type D 1. Swivel the connecting socket downwards.
2. Attach the trailer.
3. Connect the trailer plug to the socket and fasten the breakaway
stopping cable to the eye on the
carrier.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle / trailer combination is
selectively braked until the snaking ceases. While system is working keep
steering wheel as still as possible.
Trailer stability assist is a function of
the Electronic Stability Control 3 170.

Vehicle care217When the vehicle battery is being
replaced, please 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 battery is always replaced by the same type of battery.
The vehicle battery has to be
replaced by a workshop.
Stop-start system 3 156.
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 3 249.
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, such as
the air conditioning, the heated rear
window, heated steering wheel, etc.
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.

218Vehicle care● See the Owner's Manual forfurther information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Heating functionalities Notice
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will
be resumed after some minutes.
Power saving mode
This mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
Infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.Deactivating power saving mode
Power saving mode is deactivated
automatically when the engine is
restarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutes

bleeding procedure differs between
the engine types 3 268. Fuel up with
at least five litres of diesel before
starting the bleeding procedure.
