When you start the engine after the 12-volt vehicle battery has been totally discharged or changed,
you may find that system settings (time, date, personal convenience settings and programming) and
user accounts have been changed or deleted. Check and correct the settings as necessary once the
12-volt vehicle battery has been sufficiently charged.
Vehicle settings menu
First read and observe the introductoryinformation and safety warnings⇒Introduction 
You can switch individual functions and systems on and off and make settings in the vehicle settings
of the Infotainment system.
Opening the Vehicle settings menu
Switch on the ignition.
Switch on Infotainment system if necessary.
Press the button or function button.
Touch the Vehicle and function buttons to open the Vehicle settings menu.
Touch the corresponding function buttons to open additional menus in the Vehicle settings menu or
to make settings in the menu options.

Performance monitor
First read and observe the introductoryinformation and safety warnings⇒Introduction 
The performance monitor is a display for sporty driving. The digital instruments display real-time
values for engine power, temperature and acceleration that are determined by sensors on the
vehicle. This provides the driver with an overview of driving dynamics.

Fig. 23 On the Infotainment system display: performance monitor.

The belt tensioners are activated by sensors in the event of severe frontal, side and rear collisions.
They tighten the seat belts against the direction in which they are pulled. Any slack in the seat belt is
retracted, which can reduce the forward movement of the vehicle occupants and their movement in
the direction of the impact. The belt tensioner works together with the airbag system. If the vehicle
rolls over, the belt tensioners will not be activated if the side airbags are not triggered.
Fine dust may be produced when belt tensioners are triggered. This is quite normal and does not
mean there is a fire in the vehicle.
Belt tension limiter
The belt tension limiter reduces the pressure exerted by the seat belt on the body in an accident.

All safety regulations must be observed when the vehicle or components of the system are
scrapped. Qualified workshops are familiar with these regulations ⇒ Service and disposal of belt
tensioners .
Service and disposal of belt tensioners
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Seat belts may become damaged during any work on the belt tensioners or while removing or
refitting any vehicle parts in conjunction with any other repair work. This damage will not always be
noticeable. The consequence may be that the belt tensioners could function incorrectly, or not
function at all, in the event of an accident.
Regulations must be observed to ensure that the effectiveness of the belt tensioner is not reduced
and that removed parts do not cause any injuries or environmental pollution. Qualified workshops
are familiar with these regulations.

WARNING
The risk of severe or fatal injuries may be increased if the seat belts, belt retractors and belt
tensioners are not used correctly or if they are repaired by a non-professional. As a result, the belt
tensioners may not be triggered when they should be, or they may be triggered unexpectedly.
Any repairs, adjustments or removal and refitting of parts in the belt tensioners or seat belts should
always be carried out by a qualified workshop and never by yourself ⇒ Accessories, modifications,
repairs and renewal of parts .
Belt tensioners and belt retractors cannot be repaired. They must be replaced.

The airbag modules and belt tensioners may contain perchlorate. Observe the applicable legislation
regarding disposal.
Proactive occupant protection system

The airbags can protect vehicle occupants during frontal and side collisions by reducing their
movement in the direction of the collision.
Each triggered airbag is filled by a gas generator. This causes the airbag covers to break open and the
airbags inflate forcefully to cover their deployment zones within milliseconds. Once a vehicle
occupant wearing a seat belt starts to sink into the inflated airbag, the gas inside the airbag starts to
escape to cushion the occupant and slow down their movement. This reduces the risk of severe and
fatal injuries. A triggered airbag will not always prevent other injuries from occurring, such as
swelling, bruising, burning and grazing. Deployment of an airbag can also result in frictional heat.
The most important factors for triggering the airbag are the type of accident, the angle of impact,
the vehicle speed and the type of object with which the vehicle collides. Therefore, visible damage
to the vehicle does not always mean that the airbag should have been triggered.
The triggering of the airbag system depends on the vehicle deceleration rate caused by the collision
and registered by the electronic control unit. If this rate is below the reference value programmed
into the control unit, the airbags will not be triggered, even though the vehicle may be badly
damaged as a result of the collision. Vehicle damage, repair costs or even the lack of vehicle damage
in an accident is not necessarily an indication of whether an airbag should inflate or not. It is not
possible to define a range of vehicle speeds and reference values, since the circumstances will vary
considerably between one collision and another. It is therefore impossible to cover every possible
kind and angle of impact that would trigger the airbags. Important factors in the triggering of the
airbag include, for example, the nature (hard or soft) of the object that the vehicle hits, the angle of
impact as well as vehicle speed.
Airbags serve only as a supplement to the three-point seat belt in some accident situations when the
vehicle's deceleration is sufficient to trigger the airbags. Airbags can be triggered only once and only
in certain situations. The seat belts are always there to provide protection in situations when the
airbags are not triggered or have already been triggered. For example, if the vehicle collides with a
further vehicle following the initial collision, or is hit by another vehicle.
The airbag system is part of the vehicle's overall passive safety concept. The airbag system can work
effectively only when the occupants are wearing their seat belts correctly and have assumed a
proper sitting position ⇒ Sitting position .
Components of the vehicle safety concept
The following vehicle safety equipment makes up the vehicle's safety concept to reduce the risk of
severe and fatal injuries. Depending on the vehicle equipment level, some of the equipment may not
be fitted in your vehicle or may not be available in some countries.
Optimised seat belts for all seats.
Front airbags for driver and front passenger.
Airbag indicator lamp .
Control units and sensors.
Adjustable steering column.
If applicable, mounting points for the top tether for child seats.

Close driver or front passenger door.
Touch the sensor ⇒ Fig. 53Ⓑ  on the outside of the driver or front passenger door handle.

Vehicle unlocking is confirmed by all the turn signals flashing twice and locking by the turn signals
flashing once.
Locking and unlocking the boot lid
When the vehicle is locked, the boot lid will be unlocked automatically if you open it when a vehicle
key is located within the operating range of the boot lid ⇒ Fig. 52 .
The boot lid is locked automatically after it is closed.
If the vehicle is completely unlocked, the boot lid will not lock automatically when closed.
Temporarily deactivating Keyless Access
Keyless Access can be deactivated temporarily as described below so that the vehicle cannot be
unlocked and started due to misuse by unauthorised third parties.
Lock the vehicle with the button in the vehicle key.
In addition, touch the sensor on the outside of the door handle ⇒ Fig. 53Ⓑ  once within five
seconds. Do not reach into the door handle.
Keyless Access is temporarily deactivated.
Check deactivation by waiting for at least ten seconds and then pull the door handle again. It should
not be possible to open the door.
When the vehicle is next unlocked, it can be unlocked only using the vehicle key. The Keyless Access
locking and starting system is reactivated the next time the vehicle is unlocked.
Operating the convenience functions
All electric windows and the glass roof can be closed automatically.
Keep a finger on the sensor ⇒ Fig. 53Ⓑ  of the driver or front passenger door handle for a few
seconds until the windows and glass roof are closed.
The sensor functions can be set in the Vehicle settings menu in the Infotainment system
⇒ Infotainment system controls and displays .

The unlocking function is deactivated for a few seconds so that you can check that the vehicle has
been locked successfully.

If the message Keyless Access system faulty appears on the instrument cluster display, there may be
a malfunction in the Keyless Access system. Go to a qualified workshop.

If there is no vehicle key in the vehicle or if it is not detected, a message will be shown on the
instrument cluster display. This may occur if the vehicle key is subject to interference by another

radio signal or is covered by another item, e.g. an aluminium case ⇒ Starting and stopping the
engine .

If the vehicle has a DSG® dual clutch gearbox, it can be locked only if the selector lever is in
position P.

The entire vehicle will be unlocked if the sensor is touched twice, even if a single door has already
been unlocked.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Keyless Access does not work
The function of the sensors may be restricted if they become very dirty.

Doors and central locking button
Introduction
This chapter contains information on the followingsubjects:
⇒ Indicator lamp in the driver door 
⇒ Automatic locking and unlocking 
⇒ Central locking button 
⇒ Opening and closing the driver door manually 
⇒ Manually closing the front passenger door and rear doors 
⇒ Childproof lock 
⇒ SAFELOCK 
⇒ Troubleshooting 
If the vehicle key or central locking fails, the doors can be locked manually and, in some cases, also
unlocked manually.
The central locking system enables you to centrally lock and unlock all the doors, the boot lid and
the tank flap of the vehicle.

With some equipment levels, the vehicle may have a SAFELOCK mechanism.
SAFELOCK deactivates the door release levers if the vehicle has been locked. This makes it more
difficult to break into the vehicle. The doors can no longer be opened from the inside ⇒ .
Press the button on the vehicle key once.
