● Always take the manufacturer assembly in-
structions
into account.
● Use only crossbars and the roof carrier sys-
tem when they ar
e in perfect condition and
are properly secured.
● Secure the crossbars and the roof carrier
syst
em properly.
● Check threaded joints and attachments
travel
ling and if necessary tighten them after
you have travelled a short distance. When
making long trips, check the threaded joints
whenever you stop for a rest.
● Always fit the special roof carrier systems
correctly
for wheels, skis and surfboards, etc.
● Do not modify or repair the crossbars or
roof c
arrier system. Note
Always read the assembly instructions that
come w ith the c

rossbars and the roof carrier
system carefully and keep them in the vehi-
cle. Loading the roof carrier system
The load can only be secured if the crossbars
and the roof
c

arrier system are properly in-
stalled ››› .
Max imum authori

sed roof load
The maximum permissible roof load is 75 kg.
This figure comes from the combined weight
of the roof carrier, the cross bars and the load
itself on the roof ››› .
A lw
a

ys check the weight of the roof carrier
system, the cross bars and the weight of the
load to be transported and weigh them if
necessary. Never exceed the maximum au-
thorised roof load.
If you are using cross bars and a roof carrier
with a lower weight rating, you will not be
able to carry the maximum authorised roof
load. In this case, do not exceed the maxi-
mum weight limit for the roof carrier which is
listed in the fitting instructions.

Viewing Climatronic information
On the screen of Climatronic control unit and
on the screen of the factory-fitted Easy Con-
nect system, the theoretical values of the
temperature zones are shown.
The unit of temperature measurement can be
changed in the Easy Connect system.
Dust and pollen filter
The dust and pollen filter with its activated
charcoal cartridge serves as a barrier against
impurities in the air taken into the vehicle in-
terior.
The dust and pollen filter must be changed
regularly so that air conditioner performance
is not adversely affected.
If the filter loses efficiency prematurely due
to use in areas with very high levels of air
pollution, the filter must be changed more
frequently than stated in the Service Sched-
ule. WARNING
Reduced visibility through the windows in-
cr e

ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged,
so as to maintain good visibility of everything
outside.
● The maximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. » 163

● Never sw it

ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake. As you cannot steer and brake in the normal
manner
, ther

e is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehic
le is in motion. Otherwise, the steer-
ing could suddenly lock, making it impossible
to steer the vehicle: risk of accident!
● Always take the key with you when you
leav
e the vehicle. This is particularly impor-
tant if there are children in the vehicle, as
they might otherwise be able to start the en-
gine or use power-operated equipment (e.g.
the electric windows), which could cause in-
juries. CAUTION
If the engine has been running under high
loa d f

or a long time, there is a risk of heat
building up in the engine compartment after
it has been switched off; this could cause en-
gine damage. For this reason, you should idle
the engine for approximately 2 minutes be-
fore you switch it off. Note
● Aft er the en

gine is switched off the radiator
fan may run on for up to 10 minutes, even if
the ignition is switched off. It is also possible
that the fan turns itself on once more if the
coolant temperature increases due to the
heat accumulated in the engine compartment
or due to its prolonged exposure to solar ra-
diation. ●
If the v

ehicle is stopped and the Start-Stop
system* switches off the engine, the ignition
remains switched on. Make sure that the igni-
tion is switched off before leaving the vehi-
