-hand exterior mirror moves to the 
saved position. 
The front passenger exterior mirror will move out of the position saved for reversing when the 
vehicle is driven forwards faster than approximately 15 km/h (9 mph) or when the rotary knob is 
moved out of position  into another position. 
 
WARNING 
Injuries can be sustained if you do not take care when folding the exterior mirrors in and out. 
Fold the exterior mirrors in or out only when there is no obstruction in the path of the mirror. 
Always ensure that no fingers are caught between the exterior mirror and the mirror base when the 
exterior mirrors are moved. 
 
NOTICE 
Always fold in exterior mirrors before using an automatic car wash. 
Do not fold electrically folding exterior mirrors in or out manually as this can damage the electric 
drive. 
 
The exterior mirror heating should be switched off when it is no longer needed. If the heating is left 
on, this will result in unnecessary fuel consumption. 
 
If there is a fault, the electric exterior mirrors can be adjusted by hand by pressing on the outside of 
the mirror.

 Introduction 
This chapter contains information on the followingsubjects: 
Front controls
Air recirculation mode
Seat heating
Steering wheel heating
Troubleshooting
The following systems may be installed in the vehicle 
Both the manual air conditioning system and Climatronic heat, cool and dehumidify the air. It works 
most effectively when the windows and the glass roof are closed. If heat has built up in the vehicle 
interior, ventilating the vehicle can speed up the cooling process. 
Display of activated functions 
Lit up LEDs on rotary knobs and buttons indicate that the function is switched on. 
 
WARNING 
Poor visibility through the windows increases the risk of collisions and accidents, which can cause 
serious injuries. 
Keep all windows free from ice, snow and condensation to maintain good visibility. 
Adjust the heating, air conditioning system and rear window heating so that condensation does not 
form on the windows. 
Only set off once all windows are clear. 
Use air recirculation mode for a short period only. If the cooling system is switched off, condensation 
can form on the windows very quickly in air recirculation mode and reduce visibility considerably.

WARNING 
Stale air can quickly make the driver tired and affect their concentration, which in turn can cause 
collisions, accidents and serious injuries. 
Never switch off the blower or switch on the air recirculation mode for an extended period as this 
prevents fresh air from entering the vehicle interior. 
 
NOTICE 
Food, medicine and other items that are sensitive to heat or cold could be either damaged or 
rendered useless by the air flowing out of the vents. 
Never leave food, medicines or other temperature-sensitive objects in front of the vents. 
 
NOTICE 
If the air conditioning system is not working, switch the air conditioning system off immediately and 
have it checked by a qualified workshop. This can help to prevent secondary damage.

WARNING 
Stale air can quickly make the driver tired and affect their concentration, which in turn can cause 
collisions, accidents and serious injuries. 
Never use the air recirculation mode for an extended period as no fresh air will enter the vehicle 
interior. 
If the cooling system is switched off, condensation can form on the windows very quickly in air 
recirculation mode and reduce visibility considerably. 
Switch off the air recirculation mode when it is no longer required. 
 
NOTICE 
In vehicles with an air conditioning system, do not smoke when the air recirculation mode is 
switched on. The smoke can leave a residue on the cooling system evaporator and the dust and 
pollen filter with pollution filter insert, producing a lasting unpleasant odour. 
 
When reversing the vehicle, or when the wash and wipe system is being used, the air recirculation 
mode will switch on to prevent odours from entering the vehicle interior. 
Climatronic 
 
If the outside temperature is very high, the manual air recirculation mode can be activated for a 
short time to help cool the vehicle interior more quickly.
