Service menu

The instrument cluster shows the status of the start/stop system each time the button is pressed.
If the start/stop system has switched the engine off, it will start again as soon as the system is
deactivated manually with the button.
Always deactivate the start/stop system manually when driving through water.
Start/stop mode when Adaptive Cruise Control (ACC) is active
The engine will be switched off after the Adaptive Cruise Control (ACC) has brought the vehicle to a
standstill via an active braking intervention ⇒ Adaptive Cruise Control (ACC) .
The engine will be switched off after the Adaptive Cruise Control (ACC) has brought the vehicle to a

Vehicles with dual clutch gearbox DSG: when adaptive cruise control (ACC) is activated, the
dual clutch gearbox DSG® can switch to coasting mode.
Vehicles with dual clutch gearbox DSG: when adaptive cruise control (ACC) is activated, the
dual clutch gearbox DSG® can switch to coasting mode.
In the following instances, the engine will restart when the Adaptive Cruise Control (ACC) is active:
If the accelerator is depressed.
When the Adaptive Cruise Control (ACC) has resumed speed and distance control.
If the vehicle ahead has moved on.

WARNING
Never switch off the engine or the ignition while the vehicle is in motion. This can lead to a loss of
vehicle control, accidents and serious injuries.
The airbags and belt tensioners will not work if the ignition is switched off.
The brake servo will not work when the engine is switched off. That is why more pressure on the
brake pedal is needed to brake the vehicle when the engine is switched off.
The power steering will not work when the engine is not running. More power is needed to steer the
vehicle when the engine is switched off.
When the ignition is switched off, the steering lock may activate and you will no longer be able to
steer the vehicle.
The start/stop system must be deactivated if work is to be carried out in the engine compartment.

NOTICE

Distance from vehicle ahead too close
The warning lamp lights up red.
Brake request by ACC ⇒ Adaptive Cruise Control (ACC) .
The brake pedal was not depressed or not fully depressed.
Brake immediately.
Gearbox overheated
The indicator lamp lights up yellow.
A signal tone may also be given. A text message may also be shown on the instrument cluster
display.
The DSG® dual clutch gearbox can become too hot, for example, if the vehicle pulls off regularly,
during long periods at crawling speed, or in stop-and-go traffic.
Do not drive on!
Allow the gearbox to cool down in selector lever position P⇒ .
Do not drive on if the indicator lamp does not go out.
Seek expert assistance. Failure to do so could result in considerable damage to the gearbox.
Releasing the selector lever lock manually
If the power fails in the vehicle (for example if the 12-volt vehicle battery is flat) and the vehicle has
to be towed, the selector lever lock must be released manually. Seek expert assistance for this.
The manual release mechanism is located under the cover of the gearshift gate.
Removing the cover of the gearshift gate:
Switch on the electronic parking brake. If the electronic parking brake cannot be switched on, the
vehicle will have to be prevented from rolling away using other means.
Switch off the ignition.
Carefully pull the cover upwards in the area around the selector lever gaiter with connected
electrical wiring ⇒ Fig. 108 .
Pull the cover up and over the selector lever ⇒ .
Depending on the vehicle equipment, there are two possible manual release mechanism variants.
Releasing the selector lever lock manually:
Using the flat blade of the screwdriver from the vehicle toolkit, carefully push the release lever in the
direction of the arrow and keep it in this position ⇒ Fig. 108 .
Press the lock button on the front of the selector lever and move the selector lever into position N.

If the text message and signal tone are repeated approximately every 10 seconds, park the vehicle
safely as soon as possible and switch the engine off. Allow the gearbox to cool down.
Do not drive on until the signal tone stops in order to avoid damage to the gearbox. You should not
pull away or drive the vehicle at very low speeds while the gearbox is overheated.
Downhill speed control
The downhill speed control system helps when braking and travelling downhill in vehicles with a
DSG® dual clutch gearbox ⇒ . The downhill speed control uses the braking power of the engine.
The DSG® dual clutch gearbox selects the best gear depending on the steepness of the gradient 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 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 6%.
AND: if the selector lever is in position D/S.
In addition, if the cruise control system or Adaptive Cruise Control (ACC) is switched off: if the
vehicle speed is less than approximately 80 km/h (50 mph) or the brake pedal is depressed.
In addition, if the cruise control system or Adaptive Cruise Control (ACC) is active: if the stored speed
is exceeded.
Deactivating downhill speed control automatically:
If the downhill gradient becomes less steep.
OR: if the gearbox shifts up a gear because the engine speed is higher than approximately 4,500 rpm.
Or additionally if the cruise control system or Adaptive Cruise Control (ACC) is active: if the stored
speed can be maintained.

WARNING
The intelligent downhill speed control technology cannot overcome the laws of physics, and
functions only within the limits of the system. Never let the extra convenience afforded by pull-away
assist systems tempt you into taking any safety risks when driving.
Unintentional vehicle movements can cause serious injury.
The downhill speed control cannot replace the full concentration of the driver.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions.

WARNING
Always avoid traversing a slope ⇒ Traversing a slope .
Vehicle occupants should never leave the vehicle via the doors facing down the hill when stopped
sideways on a steep hill. The combined centre of gravity of the vehicle and its payload (vehicle
occupants and payload) can shift and cause the vehicle to roll over and roll down the incline. Always
leave the vehicle slowly via the doors which open up the incline ⇒ Traversing a slope .

WARNING
The cruise control system has been designed for use on surfaced roads only. The cruise control
system is not suitable for use offroad and may even be hazardous. If you use the cruise control
system while driving offroad, you may lose control over the vehicle and sustain serious injuries.
Never use the cruise control system when driving offroad.

WARNING
The area monitoring system (Front Assist) was developed for use on surfaced roads only. The area
monitoring system is not suitable for use offroad and may even be hazardous. If you use the area
monitoring system while driving offroad, you may lose control over the vehicle and sustain serious
injuries.
Never use the area monitoring system when driving offroad.

WARNING
Driving the vehicle when the fuel level is too low could lead to your vehicle breaking down offroad,
accidents and serious injuries.
When the fuel level is too low, the fuel supply to the engine could be irregular, especially when
driving up or down hills and inclines.
The steering, all driver assist systems and brake support systems will not function if the engine
sputters or stops completely due to a lack of fuel or irregular fuel supply.
Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel and breaking
down.

NOTICE

Changing to Adaptive Cruise Control (ACC)
Press the button.
The speed limiter is switched off.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Control is automatically interrupted.
Malfunction. Switch off the speed limiter and go to a qualified workshop.
For safety reasons, the speed limiter does not fully deactivate itself until you release the accelerator
once or switch the system off manually.
Adaptive Cruise Control (ACC)
Introduction
This chapter contains information on the followingsubjects:
⇒ Special driving situations 
⇒ Limits of ACC 
⇒ Switching ACC on and off 
⇒ Setting ACC 
⇒ Troubleshooting 
The Adaptive Cruise Control (ACC) maintains a speed selected by the driver. If the vehicle
approaches a vehicle in front, the ACC automatically adapts the speed so that a distance you have
selected is maintained.
Speed range
ACC controls the vehicle in the speed range between 30 km/h (20 mph) and 160 km/h (100 mph)
or 210 km/h (130 mph). This speed range may differ in certain markets.
Driving with ACC
You can override the ACC at any time. Control will be interrupted when you brake. If you accelerate,
control will be interrupted for the duration of the acceleration process and will then continue again.
Control by ACC is less dynamic when towing a trailer ⇒  . The ACC will not perform control operation
if the trailer's brake lights are faulty.
Does the vehicle have ACC?
The vehicle is equipped with ACC if you can make settings for ACC in the vehicle settings of the
Infotainment system ⇒ Vehicle settings menu .
Brake request

If automatic deceleration by ACC is not sufficient, ACC will request you to brake additionally by a
corresponding message on the instrument cluster. In addition, the red warning lamp lights up
and an acoustic warning is given. Brake immediately!
Radar sensor
ACC detects driving situations by means of the radar sensor at the front of the vehicle ⇒ Front view .
The radar sensor has a range of up to approximately 120 m.

WARNING
The intelligent technology used in the ACC cannot overcome the laws of physics, and functions only
within the limits of the system. Never let the extra convenience tempt you into taking safety risks
when driving. Careless or unintentional use of the Adaptive Cruise Control (ACC) can cause accidents
and lead to serious injury. The system is not a substitute for the full concentration of the driver.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic
conditions.
Never use the ACC in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. due
to snow, ice, wet roads, loose chippings, or on flooded roads.
Never use the ACC offroad or on non-surfaced roads. The ACC is designed for use on surfaced roads
only.
The ACC will not react to stationary vehicles.
The ACC will not react to persons, animals or vehicles crossing or approaching in the same lane.
Brake immediately if speed reduction by ACC is not sufficient.
Brake immediately if a request to brake appears on the instrument cluster display.
Brake if the vehicle starts rolling unintentionally after a request to brake.
Be prepared to control the speed yourself at all times.
Special driving situations

Fig. 118 On the instrument cluster display: slower vehicle detected in the left-hand lane (illustration).

If the radar 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.
