202Driving and operatingdriver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent of the driver's level of vigilance.
The driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 40 mph for
a few minutes.
System limitations
In the following situations, the system
may not operate properly or even not operate at all:
● poor visibility caused by inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc.● dazzle caused by headlights of oncoming vehicles, low sun,
reflections on damp roads,
leaving a tunnel, alternating
shade and light etc.
● windscreen area in front of the camera covered by dirt, snow,
stickers etc.
● no lane markings detected or multiple lane markings due to
roadworks
● close vehicles ahead
● winding roads or narrow roadsFuel
Fuel for petrol engines The petrol engines are compatible
with bio-fuels that conform to current
and future European standards and
and can be obtained from filling
stations:
Petrol that meets the EN228
standard, mixed with a biofuel
meeting the EN15376 standard.
Use fuel with the recommended
octane rating. A lower octane rating
can reduce engine power and torque
and slightly increases fuel
consumption.

216Vehicle care9Warning
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.
The washer fluid level has to be
underneath the MAX mark.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 254.
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 fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.

218Vehicle careDischarge 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 vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● Explosive gas may be present in the vicinity of the vehicle battery.
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.
Changing into power saving mode
When power saving mode is
activated, a message appears in the
Driver Information Centre indicating
Power saving mode .
An active telephone call using the
hands-free option will be maintained
for around 10 minutes longer.
