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.

⇒ Troubleshooting
Push-starting or tow-starting
For technical reasons, your vehicle must not be push-started or tow-started. Use jump leads to
start the engine instead ⇒ Jump starting.
Ignition lock
Switching the engine off while the vehicle is moving makes it more difficult to stop the
vehicle. This can lead to loss of control of the vehicle and to accidents and severe injuries.
•Braking and steering support systems, the airbag system, the belt tensioners and other
items of safety equipment in the vehicle are only active when the engine is running.
•Never switch the engine or ignition off while the vehicle is in motion.
WARNING
The risk of serious injury can be reduced with the engine running or when starting the
engine.
•Never start or run the engine in unventilated or closed rooms. The exhaust fumes
contain carbon monoxide, an odourless and colourless toxic gas. Carbon monoxide
can cause people to lose consciousness. It can also cause death.
•Never start or run the engine if oil, fuel or any other highly flammable fluids are under
or near the vehicle, or are leaking out of the vehicle, e.g. as the result of damage.
•Never leave the vehicle unattended with the engine running, particularly if a gear or
position has been selected. The vehicle could move suddenly or something
unexpected may happen that may cause damage, fire and serious injuries.
•Never use a start booster. Start boosters may explode and cause the engine to
suddenly run at high revs.
WARNING
The components of the exhaust system become very hot. This can cause fires and serious
injuries.
•Never park the vehicle where parts of the exhaust system can come into contact with
inflammable material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt
fuel.
•Never apply additional underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converters, heat shields or particulate filter.
WARNING
Automatic ignition switch-off
The ignition switches off automatically after a short time if the driver moves away from the vehicle
with the vehicle key when the ignition is switched on. If the dipped beam headlights were switched
on at the time, the side lights will remain switched on for approximately 30 minutes. The side lights
can be switched off manually ⇒ Lights or by locking the vehicle ⇒ Central and manual locking.
Once the vehicle detects that the driver is absent when the engine stop is active, the ignition will
switched off automatically after a certain period of time.
Automatic ignition switch-off in vehicles with a start/stop system
When all the following conditions are fulfilled at the same time, the vehicle ignition will be switched
off automatically when engine stop is active and when the vehicle is stationary:
•The driver removes their seat belt.
•No pedals are depressed.
•The driver door is opened.
If the ignition is deactivated automatically while the dipped beam headlights are switched on ,
the side lights remain switched on for around 30 minutes.
The side lights can be switched off manually or will go off when the vehicle is locked.
Engine restart function
If no valid vehicle key is detected in the vehicle interior once the engine has been switched off, the
engine can be restarted within approximately 5 seconds. A corresponding message appears on the
instrument cluster display.
After this time, the engine cannot be re-started without a valid vehicle key in the vehicle interior.
Before leaving the vehicle, always switch off the ignition manually and observe any
information shown in the instrument cluster display.
Leaving the vehicle stationary for long periods with the ignition switched on can discharge
the 12-volt vehicle battery so that the engine can no longer be started.
