If the problem persists, go to a qualified workshop.
Changes in the activation behaviour of the rain/light sensor
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain/light
sensor
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 can cause the wipers to be activated.
Salt deposits: in winter, salt deposits can cause the wipers to continue to wipe the windscreen when
it is almost dry.
Dirt: 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 exteriorat 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 impairment of the
sensitive surfaces and adjust accordingly. Depending on the size of the stone impact, the activation
behaviour of the rain/light sensor may be changed.
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 window. The wiper will stop moving if
the obstacle continues to block its path. Remove the obstacle and switch the wiper 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
your driving style accordingly.
NOTICE
Free access to the pedals must be ensured at all times. For example, a larger brake pedal travel will
be necessary in order to stop the vehicle if a brake circuit fails. The brake pedal will have to be
depressed further and harder than normal.
Gear-change indicator

Key to Fig. 96
Currently selected gear.
Recommended gear.
Depending on the vehicle's equipment level, the instrument cluster display may indicate a gear
which should be selected to reduce fuel consumption while the vehicle is in motion.
Vehicles with DSG dual clutch gearbox: the selector lever must be in the Tiptronic position for
this Changing gear using Tiptronic
No recommended gear is indicated if the most suitable gear is already selected. The currently
selected gear is displayed.
Information on cleaning the particulate filter
The engine management system recognises when the particulate filter is becoming saturated and
supports regeneration of the filter by recommending the most suitable gear when driving. Compared
with normal driving, this may mean driving with an increased engine speed Particulate filter
CAUTION
The gear-change indicator is designed only to assist the driver and cannot replace the driver's own
judgement.
The driver has full responsibility for selecting the correct gear in all situations, e.g. when overtaking
or when driving up and down hills.
Driving in the correct gear can help to reduce fuel consumption.
WARNING
New brake pads will not have the optimal braking effect when first fitted.
New brake pads cannot generate the full braking effect during the first 300 km and must first be run
in. A reduced braking effect can be increased by applying more pressure to the brake pedal.
In order to reduce the risk of accidents, serious injuries and the loss of control over the vehicle, you
must drive particularly carefully when driving with new brake pads.
Never drive too close to other vehicles during the run-in time for the new brake pads and never
create a driving situation that will place a heavy load on the brakes.
WARNING
Overheated brakes reduce the braking effect and considerably increase the braking distance.
When driving downhill, the brakes are placed under particular strain and become hot very quickly.
Before driving down a long, steep gradient, reduce speed and change to a lower gear (with manual
gearboxes or in Tiptronic mode with the automatic gearbox). This will make use of the engine
braking effect and relieve the load on the brakes.
Non-standard or damaged front spoilers could restrict the airflow to the brakes and cause them to
overheat.
WARNING
Wet brakes or brakes coated with ice or road salt react more slowly and require longer braking
distances.
Carefully apply the brakes to test them.
Always dry brakes and clean off any coating of ice and salt with a few cautious applications of the
brake when visibility, weather, road and traffic conditions permit.
WARNING
Driving without the brake servo can considerably increase the braking distance and thus cause
accidents and serious injuries.
Never switch the engine or ignition off while the vehicle is in motion.
If the brake servo does not function or the vehicle is being towed, the brake pedal will have to be
depressed more forcefully as the braking distance will be increased due to the lack of assistance for
the brake system.

The gear that is currently selected will be maintained when the Tiptronic programme is selected.
This remains the case as long as the system does not automatically carry out a change of gear due to
the current driving situation.
Operating Tiptronic with the selector lever
Push the selector lever from position D/S to the right into the Tiptronic gate.
Tap the selector lever forwards or back to shift gear up or down Fig. 106
When tapping the selector lever in the Tiptronic gate, it is not necessary to press the lock button on
the selector lever.
Operating Tiptronic with the paddles
Pull the right paddle Fig. 107towards the steering wheel to change up a gear.
Pull the left paddle towards the steering wheel to change down a gear.
To leave Tiptronic mode, pull the right paddle towards the steering wheel for approximately one
second.
Tiptronic is automatically deactivated if the selector paddles are not operated for some time and the
selector lever is not in the Tiptronic gate.
NOTICE
When accelerating, the gearbox automatically shifts up to the next gear shortly before the maximum
permitted engine speed is reached.
When shifting down a gear manually, the gearbox will not change gear until the engine can no longer
be overrevved.

Operating the speed limiter with the multifunction steering wheel
Troubleshooting
The speed limiter helps you to stop exceeding a stored speed.
Speed range
The speed limiter is available when driving forwards at speeds from approx. 30 km/h (20 mph).
Driving with the speed limiter
You can interrupt the speed limiter at any time by depressing the accelerator all the way down past
the point of resistance. As soon as the stored speed is exceeded, the green indicator lamp will
flash and an acoustic warning may sound. The speed remains stored in the memory.
The speed limiter function switches back on automatically as soon as the speed drops back below
the stored speed.
Displays
When the speed limiter is switched on, the instrument cluster display shows the stored speed and
the status of the speed limiter:
Shown small or grey: speed limiter not active.Shown large or white: speed limiter active.
Driving downhill
Driving downhill may cause the set speed to be exceeded.
Apply the foot brake to slow the vehicle down, and change down a gear as required.
WARNING
Always switch off the speed limiter after use to avoid unintentional speed control.
The speed limiter does not relieve the driver of their responsibility for the speed of the vehicle. Do
not drive at full throttle if this is not required.
Use of the speed limiter in adverse weather conditions is dangerous and can cause serious injury,
e.g. through aquaplaning, snow, ice, or leaves. Use the speed limiter only when the road and
weather conditions allow it to be used safely.
The speed limiter cannot limit the vehicle speed when travelling downhill. The vehicle speed can
increase under its own weight. Select a lower gear or use the foot brake to slow the vehicle down.
Operating the speed limiter with the multifunction steering wheel
adar sensor is exposed to environmental conditions that impair sensor functioning, the
system may detect this only after a certain time. For this reason, possible functional restrictions may
be displayed only after a delay at the start of the journey and when driving
Objects that cannot be detected
Persons.
Animals.
Stationary vehicles.
Crossing or oncoming vehicles.
Other stationary obstacles.
If a stationary vehicle is hidden behind a vehicle that has been detected by the adaptive cruise
control and this vehicle turns off the road or changes lane, the ACC will not react to the stationary
vehicle Fig. 120.
Bends
The radar sensor always measures straight ahead. For this reason, vehicles may be incorrectly
detected or vehicles driving ahead not detected in tight bends Fig. 119.
Vehicles outside the sensor range
Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g. motorbikes
Fig. 119.
Vehicles that change into your lane directly in front of your vehicle Fig. 120.
Vehicles with bodies or attachments that project beyond the vehicle.
WARNING
If you use ACC in the above situations, this can result in accidents and serious injuries as well as
violation of legal regulations.
Switching ACC on and off
Radar sensor
Front Assist detects driving situations by means of the radar sensor at the front of the vehicle
Front view m.
Functions included in the system
The City Emergency Braking System and Pedestrian Monitoring (depending on vehicle equipment)
are part of Front Assist and are automatically active when Front Assist is switched on.
WARNING
The intelligent technology used in Front Assist cannot overcome the laws of physics, and functions
only within the limits of the system. Never let the extra convenience afforded by Front Assist tempt
you into taking safety risks when driving. The driver is always responsible for braking in time.
If Front Assist issues a warning, brake your vehicle immediately depending on the traffic situation or
avoid the obstacle.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic
conditions.
Front Assist cannot prevent accidents and serious injuries on its own.
Front Assist can issue unnecessary warnings and carry out unwanted braking interventions in certain
complex driving situations, e.g. at traffic islands.
Front Assist can issue unnecessary warnings and carry out unwanted braking interventions when its
function is impaired, e.g. if the radar sensor is dirty or its position has been changed.
Front Assist without Pedestrian Monitoring does not react to persons. In addition, the system does
not react to animals or to vehicles that are crossing or approaching in the same lane.
If you are unsure whether your vehicle possesses Pedestrian Monitoring, please enquire about this
at a qualified workshop before starting your journey.
Be prepared to take over control of the vehicle yourself at all times.
Warning levels and braking intervention
First read and observe the introductoryinformation and safety warnings
Distance warning
The system detects when safety is endangered by driving too close to the vehicle in front. The
warning lamp lights up. Increase the distance.
