Automatic switch-off of side lights and parking lights
If the battery capacity is not sufficient for the side lights or parking light to remain switched on for
two hours, the 12-volt vehicle battery can be discharged to such an extent that it is no longer
possible to start the engine ⇒ .
In the case of standing times of more than two hours, the vehicle will detect a weak 12-volt vehicle
battery and switch off the side lights or parking light so that the engine can still be started.
WARNING
Accidents and serious injuries can occur if the vehicle is parked without sufficient illumination, as
other road users might have difficulty seeing the vehicle, or may not see it at all.
Always park the vehicle safely and with sufficient lighting. Observe any applicable local regulations.
If the vehicle lighting is required for several hours, switch on the right or left parking light if possible.
The illumination time of the parking light on one side is generally twice as long as for continuous
parking light on both sides of the vehicle.

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 around 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.
WARNING
Adjusting the exterior and interior mirrors while the vehicle is moving may cause the driver to
become distracted. This could lead to accidents and serious injuries.
Exterior and interior mirrors should be adjusted only when the vehicle is at a standstill.
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 serious 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
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.
NOTICE
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.

Always close the sun blind carefully.
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 .
Front controls
