the highest setting. Heating takes place dependent on the ambient temperature after around
two minutes.Adjust the left-hand exterior mirror.Adjust the right-hand exterior mirror.Zero
position. The exterior mirror cannot be adjusted and all functions are switched off.
Activating the exterior mirror functions
The following exterior mirror functions must be activated once in the Infotainment system in
the Vehicle settings menu ⇒ Infotainment system controls and displays :
Synchronous mirror adjustment
Synchronous mirror adjustment means that the right-hand exterior mirror is also adjusted at the
same time when you adjust the left-hand exterior mirror.
Turn the rotary knob to position .
Adjust the left-hand exterior mirror. The right-hand exterior mirror will be adjusted at the same time
(synchronously).
Correct the settings for the right-hand exterior mirror if necessary: swivel the rotary knob to
position and adjust the right-hand exterior mirror.
Folding in the exterior mirrors while parking
When the vehicle is locked or unlocked from the outside, the exterior mirrors fold in or out
automatically. For this, the rotary knob must be in position , , or .
If the rotary knob for the electrically adjustable exterior mirrors is in position , the exterior
mirrors stay folded in.
Saving and recalling the front passenger exterior mirror settings for reversing
Unlock the vehicle with the vehicle key to which the settings should be assigned.
Switch on the electronic parking brake.
Switch on the ignition.
Put the gearbox into neutral.
Select reverse gear.
Adjust the front passenger exterior mirror so that you have a good view of the kerb area, for
example.
The set mirror position will be saved and assigned to the vehicle key.
Turn the rotary knob for the exterior mirrors to position .
Select reverse gear while the ignition is switched on. The right-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.
Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .
Protection from the sun
Sun visors
Ensure that there is no one in the path of the sun blind, especially if it is closed when the roll-back
function is not active.
The roll-back function does not prevent fingers or other body parts from being pressed against the
roof frame and being injured.
When the glass roof is open, the electric sun blind can be closed only up to the front edge of the
glass roof.
Heating and air conditioning system
Heating, ventilating, cooling
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.
Switch off the air recirculation mode when it is no longer required.
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.
Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .
