Roof load
Loads carried on the roof must be securely attached. The 
car's handling is affected when transporting loads.The maximum permissible roof load for your vehicle is 75 kg. The 
load limit applies to the combined weight of the carrier system and 
the load itself.
It will not be possible to carry the full maximum load if the roof 
carrier you are using is rated for a load which is less than this figure. 
Do not exceed the maximum weight limit for the roof carrier, which 
is listed in the fitting instructions.
WARNING
•
To prevent accidents, loads carried on the roof must be 
securely attached.
•
Do not exceed the maximum roof load for the vehicle, the 
maximum axle loads or the maximum gross vehicle weight, as this 
could cause an accident.
•
When transporting heavy or bulky loads on the roof, bear in 
mind that the car's handling is affected by the extra weight on the 
roof and a possible susceptibility to cross winds. Adjust your 
speed and driving style accordingly to avoid accidents.For the sake of the environment
The increased air resistance when the roof carrier is fitted means 
that the vehicle uses more fuel. For this reason you should always 
take off the roof carrier when it is not in use.

connect equipment that generates electrical current, such as a solar 
panel or battery charger, to the 12 Volt sockets or cigarette lighter in 
order to charge the vehicle's battery.
•
Use only equipment which has been tested for electromagnetic 
compatibility in compliance with EC Directive 2004/104/EC.Note
Using electrical appliances with the engine switched off will drain 
the battery.

Heating and coolingDeluxe automatic air conditionerApplies to vehicles: with deluxe automatic air conditionerDescription
The air conditioner can be used to set a comfortable inte-
rior temperature in the vehicle.The air conditioner provides heating and ventilation and also cools 
and dehumidifies the air inside the vehicle.
The air conditioner is fully automatic and will maintain the desired 
temperature at a constant level. To achieve this, the temperature of 
the air supplied to the interior, the blower speed (volume of air 
delivery) and the air distribution are regulated automatically. The 
system also allows for the effect of strong sunlight, so there is no 
need for manual adjustment. For these reasons it is advisable to use 
the automatic mode for the comfort of all the passengers in virtually 
all conditions throughout the year ⇒page 95.
Please note:
The humidity of the air is automatically reduced when the system 
cools the interior of the vehicle. This helps to prevent condensation 
on the windows.
If the humidity and temperature outside the vehicle are high, 
condensation can drip off the evaporator in the air cooling system 
and form a pool underneath the vehicle. This is normal and does not 
indicate a leak.
If the outside temperature is low, the blower normally only switches 
to a higher speed once the coolant has warmed up sufficiently (this 
does not apply to the defrost setting).
In order to achieve maximum engine power, the air conditioner 
compressor is temporarily switched off when pulling away from a 
standstill with full throttle.The compressor also switches off if the coolant temperature is 
excessively high, to ensure adequate engine cooling under extreme 
loads.
Pollution filter
The pollution filter (a particle filter) serves as a barrier against impu-
rities in the outside air, including dust and pollen, and odours. The 
air is also filtered when the air recirculation mode is activated.
For the air conditioner to work with maximum efficiency, the pollu-
tion filter element must be replaced at the intervals specified in the 
Service Schedule.
If the vehicle is driven in areas with a high level of air pollution and 
the filter is no longer fully effective, it may be necessary to change 
the filter element more frequently.
Key-coded settings
The currently selected air conditioner settings are automatically 
stored and assigned to the remote control key.
Power management
To prevent the battery from becoming discharged and to maintain 
the necessary power level, the system will temporarily shut off the 
electrical components that are using a lot of power, or reduce the 
current they are consuming ⇒page 202. Heating systems in partic-
ular use a large amount of electrical power. If you notice, for 
instance, that the rear window heater is not working, it may have 
been temporarily switched off by the power management function, 
or regulated to a lower heat output. These systems will be available 
again as soon as sufficient electrical power is available.

Switching off air conditioner
– Press the   button to switch off the air conditioner 
and cut off the supply of fresh air from outside the 
vehicle.The air conditioner will switch on again if one of the control buttons 
is pressed.
Applies to vehicles: with deluxe automatic air conditionerAutomatic mode 
The standard operating mode for all seasons.Switching on automatic mode
– Select a temperature between +16 °C (60 °F) and +28 °C 
(84 °F).
– Press the   button.The automatic mode maintains a constant temperature inside the 
vehicle and dehumidifies the air. Air temperature, air delivery and 
air distribution are regulated automatically to reach the desired 
interior temperature as quickly as possible, and then to maintain 
this temperature. The system automatically compensates for any 
variations in the outside temperature and for the effect of direct 
sunlight.
The automatic temperature regulation only operates at temperature 
settings between +16 °C and +28 °C. If a temperature below +16 °C 
is selected, LO appears on the display. If a temperature above +28 °C 
is selected, the display will show HI. In the two extreme settings the 
air conditioner operates continuously with maximum cooling or 
heating output, and the temperature is not regulated 
automatically.

•
The blower speed may change automatically. This ensures that 
the selected temperature is reached as quickly as possible.

The blower speed cannot be regulated separately for the driver 
and front passenger sides of the vehicle.
Applies to vehicles: with deluxe automatic air conditionerAir recirculation mode 
The air recirculation setting prevents fumes etc. from 
entering the interior.Switching on the air recirculation mode
– Press the   button ⇒.
Switching off the air recirculation mode
– Press the   button again, or
– Press the   button, or 
– Press the   button.In this setting, the air is drawn from the interior of the vehicle, 
filtered and continuously recirculated. We recommend using the air 
recirculation mode in the following circumstances:
When driving through a tunnel or in queues of traffic, to prevent 
fumes entering the interior of the vehicle.
WARNING
For reasons of safety you should not leave the air recirculation 
switched on for too long. This mode prevents fresh air from 
entering the vehicle, so the windows can mist over if the air 
cooling is switched off. Bad visibility can cause an accident.Applies to vehicles: with deluxe automatic air conditionerAir distribution
