Operated by pressing ¨.
In the event of an accident with airbag
deployment the hazard warning
flashers are activated automatically.
Turn lightslever up:right turn signallever down:left turn signal
A resistance point can be felt when
moving the lever.
Constant flashing is activated when
the lever is being moved beyond the
resistance point. It is deactivated
when the steering wheel is moved in
the opposite direction or lever is
manually moved back to its neutral
position.
Activate temporary flashing by
holding the lever just before the
resistance point. Turning lights will

174Climate controlAir conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:
n:cooling4:air recirculation
Heated seats ß 3 42, Heated
steering wheel * 3 83.
Cooling 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 3 185.
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 air
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 towards 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.
● Switch on cooling n.
● Air recirculation system 4 on.
● Press air distribution switch M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all vents.
Driving and operating197ABS 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 97.
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.
Parking brake
9 Warning
Before leaving the vehicle, check
parking brake status. Control
indicator R (manual parking
brake) or m (electrical parking
brake) must illuminate constantly.
Manual parking brake9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
