The asymmetrical headlight beam

However, when driving in countries
where traffic drives on the opposite

traffic.

Daytime running lights
Daytime running light increases
visibility of the vehicle during daylight.
They are switched on automatically
when ignition is on.
Hazard warning flashers
Operated by pressing ¨.
In the event of an accident with airbag
deployment the hazard warning
flashers are activated automatically.
Climate control117Cooling n
Press n
to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running and climate control fan is switched on.
Press n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
Activated cooling may inhibit
Autostops.
Stop-start system 3 128.
Air recirculation system 4
Press 4 to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate
recirculation mode.
9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air
humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside, when cold air is
directed to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate l.
Maximum cooling Briefly open the windows so that hot
air can disperse quickly.
Driving and operating135ParkingThe most recently engaged gear (see
transmission display) remains
engaged when switching off ignition. With N, no gear is engaged.
Therefore always apply the parking
brake when switching off ignition. If
parking brake is not applied, P flashes
in the transmission display and the
key cannot be removed from the
ignition switch. P stops flashing in the
transmission display as soon as the
parking brake is slightly applied.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
Tyre pressure monitoring system
To start the sensor matching process of the tyre pressure monitoring
system, the selector lever must be
moved and held in position N for
five seconds. P illuminates in the
transmission display to indicate that
the sensor matching process can be
started.
Tyre pressure monitoring system
3 187.Manual mode
If a higher gear is selected when theengine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or too high an engine speed. A warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 96.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.
Gear shift indication
The symbol R, with a number
alongside it, is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.Electronic driving
programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or gradients.
Kickdown If the accelerator pedal is pressed
down completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
Fault
To prevent damage to the manual transmission automated, the clutch is
engaged automatically at high clutch
temperatures.
136Driving and operatingIn the event of a fault, control indicatorg illuminates. Additionally, a
warning message is displayed in the
Driver Information Centre. Vehicle
messages 3 96.
Continued driving is restricted or not
possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.Brakes
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 86.
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 87.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.
