Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Glass roof will not close
•The glass roof only works when the ignition is switched on. The glass roof can still be opened or
closed for a short time after the ignition has been switched off, provided the driver door or front
passenger door are not opened.

Adjust the steering wheel position before setting off and only when the vehicle is stationary ⇒.
•Push down the lever ⇒ Fig. 77①.
•Adjust the steering wheel so that you can hold it with both hands at its circumference at the 9
o'clock and 3 o'clock positions with your arms slightly bent ⇒ Fig. 78.
•Push the lever up firmly until it is flush with the steering column trim ⇒.
Closing the glass roof without the roll-back function can cause serious injuries.
•Always close the glass roof carefully.
•Ensure that nobody obstructs the path of the glass roof, especially if 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 sustaining injury.
WARNING
Mechanically adjusting the front seat
Always adjust the front seats to their correct position before any journey and ensure that
any passenger has fastened their seat belt.
•Push the front passenger seat as far back as possible.
•Adjust the driver seat so that there is at least 25 cm between your breastbone and the
hub of the steering wheel. Adjust the driver seat by moving it forwards or backwards
so that you are able to press the pedals to the floor with your knees still slightly bent
and so that the distance from the dash panel to your knees is at least 10 cm. If your
build makes it impossible to fulfil this requirement then you must contact a qualified
workshop so they can make any necessary modifications.
•Never travel with the backrest tilted far back. The further back the backrest is tilted, the
greater the risk of injury caused by incorrect seat belt routing or an incorrect sitting
position.
•Never travel with the backrest tilted far forwards. When a front airbag is triggered it
could force the seat backrest backwards and injure vehicle occupants on the back
seats.
•Adopt and maintain the greatest possible distance from the steering wheel and dash
panel.
•You should always sit upright with your back against the seat backrest with the front
seats properly adjusted. Do not position any body part too close where the airbags are
fitted.
•The risk of serious injury is increased for passengers on the rear seat if they are not
sitting upright because the seat belts are incorrectly positioned.
WARNING
Incorrect adjustment of the seats can cause accidents and serious injuries.
•Only adjust the seats when the vehicle is stationary. The seats could change position
unexpectedly if you attempt to reposition them while the vehicle is in motion, leading
to a loss of control of the vehicle. Furthermore, an incorrect seating position is
adopted while adjusting the seat.
•Only adjust the height and tilt of the seat or move it forwards and backwards when the
area around the seat is clear.
•To be able to make adjustments to the seats, the area around them must not be
restricted by any items.
•Only adjust the height of the rear seat or move it forwards and backwards when the
area around the seat is clear.
•The areas for adjusting and locking the seats must not be soiled.
WARNING
Improper use of seat covers or protective covers may lead to the electrical seat controls
being operated accidentally and the front seats moving unexpectedly while the vehicle is
moving. You could lose control over the vehicle. This could result in serious injury and
accidents. Furthermore, this may result in damage to the electrical components in the
front seats.
•Never attach or secure seat covers or protective covers to the electrical controls.
•Do not fit seat covers or protective covers over the seats unless they have been
expressly approved for use in the vehicle.
WARNING
Cigarette lighters in the vehicle could be damaged or accidentally lit. This could lead to
serious burns and other injuries.
•Before adjusting the seats always ensure that there is no lighter on or near the
moveable parts of the seat.
•Before closing stowage areas or compartments always ensure that there is no lighter
in the way.
•Never stow lighters in stowage areas, compartments or on other surfaces in the
vehicle. High surface temperatures, especially in summer, may cause cigarette lighters
to self-ignite.

weather conditions, e.g. fog.
WARNING
Troubleshooting
Washer fluid level too low. Fill up the washer fluid reservoir as soon as possible ⇒ Washer
fluid.Fault in the rain/light sensor. Switch the ignition on and off. If the indicator lamp still lights
up permanently after you switch the ignition back on, seek expert assistance.Fault in
windscreen wipers. Switch the ignition on and off. If the indicator lamp still lights up permanently
after you switch the ignition back on, seek expert assistance.
Changes in the response of the rain/light sensor
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain/light
sensor ⇒ Vehicle overviews include:
•Damaged wiper blades: a film of water or smears caused by damaged wiper blades can
increase the time the wipers are switched on, can shorten the length of the intervals between
wipes or cause the wipers to run quickly and continuously.
•Insects: insects hitting the windscreen surface can cause the wipers to be activated.
•Salt deposits: in winter, salt deposits on the windscreen can cause the wipers to continue to
wipe the windscreen when it is almost dry.
•Soiling: dry dust, wax, windscreen coatings (lotus effect), or detergent deposits (from an
automatic car wash) can cause the rain/light sensor to become less sensitive and react too
slowly, or prevent it from reacting at all. Clean the sensitive surface of the rain/light sensor
⇒ Caring for and cleaning the vehicle exterior at regular intervals and inspect the wiper blades
for damage.
•Crack in the windscreen: a wipe cycle will be triggered if the rain/light sensor is on when the
windscreen is impacted by a stone. The rain/light sensor will then register the reduction in
sensitivity of the surfaces and adjust accordingly. The size of the crack can affect the way in
which the rain/light sensor activates the wipers.
We recommend that you use an alcohol-based glass cleaner to remove wax and polish.
The wipers will try to wipe away any obstacles that are on the windscreen. The wipers will
stop moving if the obstacle blocks their path. Remove the obstacle and switch the wipers back on
again.
Mirrors
Introduction
This chapter contains information on the followingsubjects:
⇒ Interior mirror
⇒ Exterior mirrors
You can use the exterior mirrors and the interior mirror to observe traffic behind you and adjust
driving style accordingly.
For safety reasons it is important that the driver positions the exterior and interior mirrors correctly
before starting a journey ⇒.
Looking in the exterior mirrors and the interior mirror does not allow the driver to see the entire side
and rear area of the vehicle. The area that cannot be seen is known as the blind spot. There may
be objects and other road users in the blind spot.
Adjusting the exterior and interior mirrors while driving may cause the driver to become
distracted. This can lead to accidents and serious injuries.
•Exterior and interior mirrors should only be adjusted when the vehicle is stationary.
•When parking, changing lane, or performing an overtaking or turning manoeuvre,
always pay careful attention to the area around the vehicle as objects and other road
users may be located in the blind spot.
•Always ensure that the mirrors are positioned correctly and that the rear view is not
restricted by ice, snow, condensation or any other objects.
WARNING
If you estimate the distance from traffic behind you incorrectly, you can cause accidents
and serious injuries.
•Curved mirrors (convex or aspheric) enlarge the field of vision and can make objects in
the mirror seem smaller and further away than they actually are.
•Using curved mirrors to estimate the distance from other vehicles behind you when
changing lanes can provide inaccurate results and can lead to accidents and severe
injuries.
•Whenever possible, use the interior mirror to check the exact distance between your
vehicle and following traffic or other objects.
•Ensure that you have a good view to the rear of the vehicle.
WARNING
Interior mirror
Fig. 104 On the windscreen: automatic anti-dazzle interior mirror.
Fig. 105 On the windscreen: manual anti-dazzle interior mirror.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Automatic anti-dazzle interior mirror
When the ignition is turned on, the sensors measure the incident light from the rear ⇒ Fig. 104①
and from the front ②.
The interior mirror darkens automatically depending on the measured values.
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 devices attached to the windscreen or near the interior automatic anti-dazzle mirror can
also influence the sensors ⇒.
The automatic anti-dazzle function will be deactivated in some situations, e.g. when reverse gear is
engaged.
Automatic anti-dazzle mirrors contain an electrolyte fluid which could leak if the mirror is
broken.
•The leaking electrolyte fluid can cause irritation to the skin, eyes and respiratory
organs, especially in people who suffer from asthma or similar illnesses. Immediately
ensure that there is a sufficient supply of fresh air and get out of the vehicle. If this is
not possible, open all of the windows and doors.
•If the electrolyte fluid gets into the eyes or onto the skin, immediately wash the area
with plenty of water for at least 15 minutes and consult a doctor.
•If the electrolyte fluid gets onto shoes or clothing, wash immediately with plenty of
water for at least 15 minutes. Clean shoes and clothes thoroughly before wearing them
again.
•If the electrolyte fluid is swallowed, immediately rinse the mouth with plenty of water
for at least 15 minutes. Do not induce vomiting unless instructed to do so by a doctor.
Seek medical assistance immediately.
WARNING
If the glass of an automatic anti-dazzle mirror is broken, electrolyte fluid can leak from the
mirror. This fluid corrodes plastic surfaces. Remove the fluid as soon as possible, e.g.
using a wet sponge.
