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 effectyfRUGHWHUJHQWGHSRVLWVIURPDQ

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 asphericyfHQODUJHWKHILHOGRIYLVLRQDQGFDQPDNHREMHFWVLQ
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

Emergency programme
There is a fault in the system if all the displays on the instrument cluster for the selector lever
positions have a light background. The DSG dual clutch gearbox is running in an emergency
programme. The vehicle can still be driven in the emergency programme, but only at reduced
speed and not in all gears.
In vehicles with a DSG dual clutch gearbox, you may no longer be able to select reverse gear.
In all cases you should have the DSG dual clutch gearbox checked by a qualified workshop
immediately.
Overheating of the DSG dual clutch gearbox
The DSG dual clutch gearbox can become too hot, for example, if the vehicle pulls off
frequently, drives at crawling speed for long periods, or in stop-and-go traffic. Overheating is
indicated by the warning lamp and in some cases by a text message in the instrument cluster
display. A signal tone may also be given. Stop the vehicle and allow the gearbox to cool down ⇒
.
The vehicle does not move forwards or backwards even though a position
has been selected
If the vehicle will not move in the required direction, the system may have selected the position
incorrectly. Depress the brake pedal and reselect the position.
If the vehicle still does not move in the required direction, there is a system fault. Seek expert
assistance and have the system checked.
Downhill speed control
If the vehicle is being held on the Auto Hold function, the green indicator lamp lights up.
Switch off Auto Hold if necessary ⇒ Auto Hold function.
The Hill Descent Control system in vehicles with a DSG dual clutch gearbox helps when braking
and travelling downhill ⇒. This system uses the braking power of the engine, rather than the
brakes directly.
The DSG dual clutch gearbox selects the best gear for the circumstances, depending on the
steepness of the hill and the current speed. The selector lever must be in position D/S. The downhill
speed control is not active in Tiptronic mode.
As the downhill speed control system can shift down only as far as third gear, it may be necessary
to activate the Tiptronic mode when driving down particularly steep inclines. When in Tiptronic
mode, select second or first gear manually in order to make use of the braking effect of the engine
and to relieve the load on the brakes.
The start/stop system is automatically deactivated as long as downhill speed control is active.
Activating downhill speed control automatically:
•If the downhill gradient is greater than approximately 6yb.
•AND: if the selector lever is in position D/S.

Progressive steering
Depending on the vehicle equipment level, progressive steering can adjust the force of the steering
movement in a driving situation. Progressive steering only functions when the engine is running.
In urban driving, smaller steering movements are required when parking, manoeuvring, or turning
sharply.
When driving on country roads or on the motorway, the progressive steering provides a more
sporty, direct steering response, and a dynamic feel.
