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 effectyf   R U  G H W H U J H Q W  G H S R V L W V   I U R P  D Q

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 asphericyf  H Q O D U J H  W K H  I L H O G  R I  Y L V L R Q  D Q G  F D Q  P D N H  R E M H F W V  L Q  
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.
