Instruments and controls83Warning chimesIf several warnings appear at the
same time, only one warning chime will sound.
When starting the engine or whilst driving
The warning chime regarding
unfastened seat belts has priority
over any other warning chime.
● If seat belt is not fastened.
● If a door or the tailgate is not fully
closed when starting off.
● If a certain speed is exceeded with parking brake applied.
● If a programmed speed is exceeded.
● If a warning message appears in the Driver Information Centre orInfo Display.
● If the parking assist detects an object.
● If unintended lane change occurs.
● If a fault in the automatic locking system is detected.When the vehicle is parked and/or
the driver's door is opened
● With exterior lights on.
During an Autostop ● If the driver's door is opened.
Battery voltage
When the vehicle battery voltage is
running low, the warning code 174 will
appear in the Driver Information
Centre.
1. Switch off immediately any electrical consumers which are
not required for a safe drive, e.g.
seat heating, heated windscreen
and heated rear window or other
main consumers.
2. Charge the vehicle battery by driving continuously for a while or
by using a charging device.
The warning code will disappear after the engine has been started twice
consecutively without a voltage drop.
If the vehicle battery cannot be
recharged, have the cause of the fault
remedied by a workshop.Vehicle personalisation
The vehicle's behaviour can be
personalised by changing the settings in the Info Display.
Some of the personal settings for
different drivers can be memorised
individually for each vehicle key.

Headlight aim has been preset and

When driving in countries with
opposite hand traffic, it is not
necessary to adjust the headlights.
Daytime running lights Daytime running light increases
visibility of the vehicle during daylight.
They are switched on automatically
when ignition is on.
Cornering lights
On tight bends or when turning off,
depending on the steering angle or
the indicator light signal, an additional left or right reflector is switched on
which illuminates the road in the
direction of travel. It is activated up to
a speed of 40 km/h.
Hazard warning flashers
Operated by pressing ¨
.
In the event of an accident with airbag
deployment, the hazard warning
flashers are activated automatically.
112Driving and operatingBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 71.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting-off the system performs
a self-test which may be audible.
Control indicator u 3 72.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Driving and operating121correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Lane departure warning
The lane departure warning system
observes 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 accelerator operation or speeding-up.
● No active steering.
If the driver is performing these
actions, no warning will be issued.
Activation
The lane departure warning system isactivated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on. When control indicator ) in the
instrument cluster illuminates green, the system is ready to operate.
The system is only operable at
vehicle speeds above 56 km/h and if lane markings are available.
When the system recognises an
unintended lane change, control
indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.
Deactivation
The system is deactivated by
pressing ), the LED in the button
extinguishes.
At speeds below 56 km/h the system
is inoperable.
Fault
The lane departure warning system may not operate properly when:
● The windscreen is not clean.
● There are adverse environmental
conditions e.g. heavy rain, snow,
direct sunlight or shadows.
