WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may push abutton
or as witch, for example.
They could:
R activate vehicle equipment and become
trapped, for example
R switch vehicle systems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals could be flung around the vehicle, injur-
ing the vehicle occupants. There is arisk of an
accident and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals correctly during a
journey, e.g. in an animal transport box. Driving safety systems

the following driving safety systems:

R STEERC ONTROL (Y page 77) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front,f or vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather condition sand maintain asafe 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 tyres and the road
surface. Pay particular attention to the informa- tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 353).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-loc
kBraking System)
General notes ABS regulates brake pressure in such
away that
the wheels do not lock when you brake. This
allowsy ou 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 8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristic smay be severely impaired. Addition-
ally,f urther driving safety systems are deac- 66

Overview of climat
econtrol systems General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To preven tthe windows from mistin gup:
R switch off climate control only briefly
R activat eair-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activat ethe windscreen demistin gfunction
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improvin gthe interior
climate.
The "Cooling with air dehumidification "function
is only available when the engine is running.
Optimum climate control is only achieved with
the side windows and roof closed.
The residual heat function can only be activated or deactivated with the ignition switched off
(Y page 136).
i Ventilate the vehicle for
abrief period during
warm weather, e.g. using the "Convenience
opening "feature (Y page 94). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odours. Aclogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alway sobserve
the interval for replacing the filter, which is
specified in the Service Booklet. As this
depends on environmental conditions ,e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the key
has been removed depending on various fac-
tors ,e.g. the outside temperature. The vehi-
cle is then ventilated for 30 minutes to dry the automatic climate control. Overview of climat

Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle amaximum of
two times, drive for alonger distance.
Switch the auxiliary heating on regularly once a
month for aboutt en minutes.
The auxiliary heating heats the air in the vehicle interior to the set temperature. This occurs with-out using the heat of the running engine. The
auxiliary heating is operated directly using the
vehicle's fuel. For this reason, the tank content
must be at least at reserve fuel level to ensure
that the auxiliary heating functions.
The auxiliary heating or auxiliary ventilation
automaticallya djusts to changes in tempera-
ture and weather conditions. For this reason,
the auxiliary heating could switch from ventila-
tion mode to heating mode or from heating
mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automaticallya fter 50 minutes.
This time limit can be altered. To do this, visit a
qualified specialist workshop.
You cannot use the auxiliary ventilation to cool
the vehicle interior to atemperature lower than
the outside temperature.
Before switchingon X
Turn the key to position 2in the ignition lock
(Y page 145).
X Set the desired temperature using the w
rocker switch on the front control unit.
If you do not alter the temperature before
switching on the auxiliary heating or auxiliary
ventilation, the last temperature setting will be
adopted.
Auxiliary heating or auxiliary ventilation can also
be switched on if the manuallys et climate con-
trol is activated. Optimum comfort is attained
when the system is set to automatic mode. Set the temperature to 22 †.
You can switch the auxiliary heating or auxiliary
ventilation on or off:
R using the rocker switch on the centrec onsole
(Y page 139)
R using the remote control (Y page 140)The remote control can be used to set up to
three departure times, one of which may be pre-
selected.
