good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and
weather conditions and maintainasafe distance
from the vehicle in front.D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section (
Ypage 255).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such away that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from aspeed of about 5mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 54).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally,f urther driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at aqualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 204) and dis- play messages which may be shown in the
instrument cluster (
Ypage 179).
Braking
XIf ABS intervenes:
continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo make afull brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a reminder to take extr acare while driving.
BAS (Brake Assist System)
General information
BAS operates in emergencyb raking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 54).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergencyb raking situation is
increased. There is arisk of an accident.
In an emergencyb raking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
XKeep the brake pedal firmly depressed until
the emergencyb raking situation is over.
ABS prevent sthe wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.

Wind screen
Important safetyn otes
GWARNING
If you use the wind screen in darkness or in
other conditions offeringp oor visibility, your
view to the rear is further impaired. There is a
risk of an accident.
Only use the wind screen when visibility con-
ditions are good.
GWARNING
If the wind screen is incorrectly installed, it
could detach itself during ajourney and
endanger other road users. There is arisk of
an accidenta nd injury.
Install the wind screen as described.
!Install or remove the wind screen only when
the roof is open. You could otherwise damage
the wind screen or the vehicle interior. The wind screen offers protection from the wind
when driving with the roof down.
The wind screen can be installed or removed
from the driver's side or passenger side.
For operation
sinvolvin gthe wind screen,iti s

Overview of climatecontrol systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preventt he windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control can only be operated when the
engin eisrunning. Optimum operation is only
achieved with the side windows and roof closed.
iWhen the weather is warm, ventilate the
vehicle for abrief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. Aclogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alwayso bserve
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions ,e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book- let.

Setting climate control to automatic
General notes
Automatic mode is only available with dual-zone
automatic air conditioning.
In automatic mode, the set temperature is main-
tained automatically at aconstant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
The automatic mode functions optimally when
the "Cooling with air dehumidification" function
is activated. If necessary, cooling with air dehu-
midification can be deactivated.
If you deactivate the "Cooling with air-dehumid- ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified.T he windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
