Automatic anti-dazzle interior mirror
When the ignition is switched on, the sensors measure the incident light from the rear ⇒ Fig. 86 ①
and from the front ②.
Depending on the values measured, the interior mirror dips automatically.
If the incident light on the sensors is hindered or interrupted, e.g. by a sun blind or other hanging
objects, the automatic anti-dazzle interior mirror will not function or will not function correctly.
Mobile navigation systems fitted to the windscreen or near the interior automatic anti-dazzle
interior mirror can also affect the sensors ⇒ .
The automatic anti-dazzle function will be deactivated in some situations, e.g. when reverse gear is
engaged.
Manual anti-dazzle interior mirror
Basic position: the lever on the lower part of the mirror is pointing towards the windscreen.
Pull the lever to the back to use the anti-dazzle function ⇒ Fig. 87 .
WARNING
The illuminated display from a mobile navigation device can lead to malfunctions of the interior
automatic anti-dazzle mirror and cause accidents or serious injuries.
You may not be able to precisely determine the distance from vehicles travelling behind you or from
other objects if the automatic anti-dazzle function malfunctions.
Exterior mirrors
Fig. 88 In the driver door: rotary knob for the exterior mirrors.
First read and observe the introductoryinformation and safety warnings⇒Introduction
Switch on the ignition.
Turn the rotary knob in the driver door to the desired symbol ⇒ Fig. 88 .
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
Fig. 89 In the front headliner: sun visor.
Adjustment options for the driver and front passenger sun visors:
Folded down over the windscreen.
Pulled out of the bracket and swung over towards the door ⇒ Fig. 89 Ⓐ.
Vanity mirrors
There is a vanity mirror in the folded-down sun visor. Depending on the vehicle equipment level, the
vanity mirror may have a light.
When you open the cover ⇒ Fig. 89 Ⓑ, the lamp ⇒ Fig. 89 ① lights up.
WARNING
Driving with the sun visors folded down and the sun blinds pulled out can reduce your view of the
road.
Sun visors and sun blinds should always be replaced in their holder if they are not being used.
In certain circumstances, the lamp above the sun visor will go out automatically after a few minutes.
This prevents the 12-volt vehicle battery from discharging.
Sun blind in the glass roof
Fig. 90 In the roof: button for controlling the sun blind.
The electric sun blind works when the ignition is switched on.
When the glass roof is fully tilted, the sun blind is automatically moved to a ventilation position. The
sun blind remains in the ventilation position even after the glass roof is closed.
Opening and closing the sun blind
The buttons ⇒ Fig. 90 ① or ② have two positions. In the first position, the sun blind can be
completely or partially opened or closed.
In the second position, the sun blind automatically moves to the final position when the button is
pressed briefly. Press the button again to stop the one-touch function.
Opening the sun blind: push button ① to position one. One-touch function: push button ① briefly
to position two.
Closing the sun blind: push button ② to position one. One-touch function: push button ② briefly
to position two.
Stopping the one-touch function when opening or closing the blind: push button ① or ② again.
The sun blind can still be opened or closed for several minutes after the ignition has been switched
off, provided that the driver door and front passenger door are not opened.
Roll-back function of the sun blind
The roll-back function can reduce the risk of crush injury when closing the sun blind ⇒ . The glass
roof or sun blind will open again immediately if the sun blind is unable to close because it is stiff or
obstructed.
Check to see why the sun blind has not closed.
Try to close the sun blind again.
The sun blind will open again immediately if it is still unable to close because it is stiff or obstructed.
After opening, the sun blind can be closed again within a short period of time without the roll-back
function.
If the sun blind still cannot be closed, close it without the roll-back function.
Closing the sun blind without the roll-back function
Within approximately five seconds of the roll-back function being activated, press and hold button
⇒ Fig. 90 ② until the sun blind has closed completely.
The sun blind will now close without the roll-back function.
Please go to a qualified workshop if the sun blind still cannot be closed.
WARNING
Closing the sun blind without the roll-back function can cause serious injuries.
Always close the sun blind carefully.
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 .
