The brake support systems are the anti-lock brake system (ASS), the Brake Assist system (SAS), the electronic differential lock (EDS), the traction control system (TCS) and the Electronic Stability Control (ESC).
Additional information and warnings:
• Towing a trailer 139
• Pull-away assist systems 282
• Wheels and tyres 367
• Accessories, modifications, repairs and renewal of parts 394
A WARNING
Driving with worn brake pads or with a faulty brake system can cause accidents and seri-ous Injuries.
• If the warning lamp 0 lights up either on its own or with a text message In the display of the Instrument cluster, go to a qualified workshop Immediately, have the brake pads checked and any worn brake pads replaced.
A WARNING
Incorrect parking can cause serious Injuries.
• Never remove the vehicle key from the lg-nltlon lock when the vehicle Is In motion. The steering lock may be activated and you will no longer be able to steer or control the vehl-cl e.
A WARNING (Continued)
• Never park the vehicle where parts of the exhaust system can come into contact with inflammable material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt fuel.
• Always apply the handbrake when the ve-hicle Is parked.
• Never leave children or people requiring assistance alone In the vehicle. They could release the handbrake, move the selector lev-er or gearshift lever and thus set the vehicle In motion. This can lead to accidents and se-rious injuries.
• Always take all vehicle keys with you ev-ery time you leave the vehicle. The engine can be started and electrical equipment such as the window controls can be used which could cause serious injury.
• Never leave children or people requiring assistance alone in the vehicle. They could become trapped in the vehicle in an emergen-cy and may not be able to get themselves to safety. For example, locked vehicles may be subjected to very high or very low tempera-tures, according to season. This can cause serious Injuries and illness or fatalities, espe-cially for small children.
CD
• To avoid unintentional movement when parking the vehicle, first apply the handbrake and then remove your foot from the brake ped-al.
• Always take care when driving in car parks with protruding kerbstones or bollards. Objects that protrude from the ground can damage the bumper and other components when parking the vehicle. In order to avoid any damage, stop the vehicle before the wheels can touch the bollards or kerbs.
• Drive carefully through dips in the road, over driveways, ramps, kerbstones and other objects. Low-lying vehicle components such as the bumper, spoiler and parts of the running gear, engine or exhaust system could be dam-aged.
Starting the engine, changing gear and parking I 269

A WARNING (Continued)
• If the brake warning lamp ID does not go out, or if it lights up when driving, the brake fluid level in the reservoir is too low or there is a fault in the brake system. Stop the vehi-cle Immediately and seek expert assistance 277, Brake fluid.
• If the brake warning lamp@ lights up to-gether with the ABS indicator lamp S, the control function of the ABS may have failed. This can cause the rear wheels to lock quick-ly when you brake. Locked rear wheels can lead to a loss of control of the vehicle. If pos-sible, reduce your speed and drive carefully at low speed to the nearest qualified work-shop in order to have the brake system tes-ted. Avoid sudden braking and driving ma-noeuvres on the way.
• The ABS Is not functioning correctly if the ABS indicator lampS does not go out or comes on while the vehicle is in motion. The
Handbrake

r--fl1 First read and observe the introductory L-J,::.IJ information and safety warnings & on page 269.
Applying the handbrake
• Lift the handbrake lever up fully.
• The handbrake is applied when the indicator lamp ID lights up in the instrument cluster =-page 270.
Releasing the handbrake
• Lift the handbrake lever up slightly and press the lock button ::.Fig. 223 (arrow).
• Guide the handbrake lever down whilst the lock button is pressed.
A WARNING (Continued)
vehicle can be stopped using the normal brakes only (without ABS). The protection provided by ABS is no longer available. Go to a qualified workshop as soon as possible.
• If the warning lamp 0 lights up either indi-vidually or together with a text message in the display of the instrument cluster, go to a qualified workshop immediately to have the brake pads checked or any worn brake pads replaced.
CD
Failure to observe illuminated indicator lamps and text messages can lead to your vehicle be-Ing damaged. A WARNING
Incorrect use of the handbrake can cause ac-cidents and serious Injuries.
• The handbrake should never be used to brake the vehicle, except in emergencies. The braking distance is considerably longer as only the rear wheels are braked. Always use the foot brake.
• Never drive the vehicle with the handbrake lightly applied. This can overheat the brakes and adversely affect the brake system. lt can also cause premature wear to the rear brake pads.
• Never activate the accelerator from the en-gine compartment if a position or gear has been selected and the engine is running. The vehicle can start to move even if the hand-brake Is applied.
CD
To avoid unintentional movement when parking the vehicle, first apply the handbrake and then remove your foot from the brake pedal.

l"'""'('n First read and observe the Introductory L-W.I Information and safety warnings & on page 282.
The Hill Descent Assist system supports
the driver when driving down a steep in-
cline by actively braking the vehicle.
The Hill Descent Assist reduces the engine speed and brakes actively so that the vehicle travels con-stantly at walking speed =>&.
The requirement for regulation is, among other things, that the ground allows enough grip. The Hill Descent Assist system cannot fulfil its function when driving down an icy or slippery slope.
Hill Descent Assist is regulating
• If the Hill Descent Assist is switched on using the button and the indicator lamp lights up.
• AND: the speed is less than 30 km/h (19 mph).
• AND: the gradient is at least 10%.
• AND: if the accelerator and brake are not de-pressed.
• AND: if the engine is running.
Regulation is stopped if the vehicle is accelerated or braked by the driver during regulation. The regu-lation restarts once the requirements are met again.
Hill Descent Assist does not regulate
• If the gradient is less than 10%.
• OR: The speed is greater than 30 km/h (19 mph).
• OR: If the driver brakes or accelerates.
A WARNING
Always be prepared to brake the vehicle. Ac-cidents and Injuries could occur if this is not ensured.
• The Hill Descent Assist system is only a support function and may not be able to brake the vehicle sufficiently In all situations when driving downhill.
• The vehicle may accelerate despite the Hill Descent Assist system.
Switching the Hill Descent Assist on and off
• To switch the Hill Descent Assist on, press the @=>Fig. 228 button in the centre console at speeds under approximately 30 km/h (19 mph). The indicator in the instrument cluster dis-play lights up. The indicator lamp flashes when the Hill Descent Assist system is applying the brake.
r::l The Hill Descent Assist system also works if W you reverse down a slope. • Press the button@ =>Fig. 228 in centre con-sole again to switch off the Hill Descent Assist. The indicator lamp in the instrument cluster display is switched off.

• Press button , Fig. 229 in dash panel again to switch off the rear-axle differential lock. The indica-tor lamp r. in the instrument cluster goes out.
If the engine is switched off with the rear axle dif-ferential lock switched on, the rear axle differential lock remains switched on for roughly another 30 seconds.
Not switching the rear axle differential lock on
• If you are driving on well-surfaced roads &.
• If the vehicle is being towed.
• If the brakes are being tested on a rolling road test bed.
286 I While dnving
Rear-axle differential lock cannot be switched on
The rear axle differential lock cannot be switched on in the following situations:
• if there is a large difference in the speed of ro-tation of the rear wheels
• if the drive train is loaded heavily
• If the mechanical teeth of the rear-axle differen-tial lock are '1ooth to tooth": the indicator light r. in the instrument cluster flashes.
A WARNING
Never switch the rear axle differential lock on If you are driving on a solid road surface, the vehicle is being towed or if the tyres have no traction.
• Your steering will be greatly Impaired when the rear axle differential lock has been switched on. This could mean that you lose control over the vehicle and cause serious In-juries.
CD
Switching the rear axle differential lock on while being towed can damage the drive train.
m If the rear axle differential lock is switched off W when driving through a bend, this may cause a small shudder to go through the vehicle. This is caused by the release of wind-up in the drive train. This is normal and is not a indication of damage to the vehicle.
m If you drive through bends with the rear axle W differential lock switched on, the wheels "rub" on the road surface. You might be able to hear this. The ''rubbing" of the tyres -especially on solid ground -will lead to increased wear on the tyres.

• System version 1 functions at speeds of 30-160 km/h (20 mph -100 mph).
• System version 2 functions at speeds of 30-210 km/h (20 m ph-130 m ph).
In vehicles with a dual clutch gearbox DSG®, the adaptive cruise control (ACC) can brake the vehi-cle until it comes to a complete standstill behind a vehicle in front that is stopping.
Driver prompt to take over control
There are system-specific limits on the adaptive cruise control (ACC) when driving. This means that the driver may have to control the speed and dis-tance between the vehicle and other vehicles in certain circumstances.
The driver is told to take control of the vehicle via a message on the instrument cluster display prompts a braking intervention, and a signal tone =<>page 300.
Additional information and warnings:

• Volkswagen information system =<>page 24
• Cruise control system (CCS) =<>page 295
• Area monitoring system (Front Assist) =<>page 307
• Accessories, modifications, repairs and renewal of parts =<>page 394
A WARNING
The intelligent technology used in the adap-tive cruise control (ACC) cannot overcome the laws of physics, and functions only within the limits of the system. Careless or uninten-tional use of the adaptive cruise control (ACC) can cause accidents and lead to seri-ous 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.
• Do not use the adaptive cruise control (ACC) in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. on snow, ice, wet roads, loose chippings or floo-ded roads.
A WARNING (Continued)
• Never use the adaptive cruise control (ACC) off-road or on unsurfaced roads. The adaptive cruise control (ACC) is designed for use on surfaced roads only.
• The adaptive cruise control (ACC) does not react to stationary obstacles, e.g. the tail end of a traffic jam, a vehicle that has broken down, or vehicles waiting at traffic lights.
• The adaptive cruise control (ACC) does not react to persons, animals or vehicles crossing or approaching in the same lane.
• If the adaptive cruise control (ACC) speed reduction is insufficient, you should brake the vehicle by depressing the foot brake.
• Brake the vehicle by depressing the brake if the vehicle rolls inadvertently on after the driver has been prompted to take control of the vehicle.
• If the instrument cluster display indicates that the driver should take control of the vehi-cle, you have to regulate the distance your-self.
• The driver must be prepared to take con-trol of the vehicle (by accelerating or braking) at all times.
CD
Switch off the adaptive cruise control (ACC) if you suspect that the radar sensor has been damaged. This can help to prevent secondary damage. Have the radar sensor realigned.
• Repair work on the radar sensor will require special knowledge and tools. Volkswagen rec-ommends using a Volkswagen dealership for this purpose.
m If the adaptive cruise control (ACC) does not L!J function as described in this chapter, do not use it, and have the system checked by a qualified workshop. Volkswagen recommends using a Voikswagen dealership for this purpose.
m The maximum vehicle speed when the adap-L!J live cruise control (ACC) is active is limited to either 160 km/h (1 00 m ph) or 210 km/h (130 m ph). depending on the system version.
m If the adaptive cruise control (ACC) is active, L!J unfamiliar noises may be heard during the automatic braking procedure. These are caused by the braking system. Driver assist systems I 299

Several warning and indicator lamps will light up briefly as a functional check when the ignition is switched on. They will go out after a few seconds.
A WARNING
Failure to observe the warning lamps and text messages could lead to accidents and seri-ous Injuries.
Radar sensor
Fig. 240 In the ventilation grille under the Volks-wagen badge: radar sensor® and area around the radar sensor to be kept clear@.
r--('n First read and observe the introductory L-J,:.U information and safety warnings & on page 298.
A radar sensor is fitted to the front bumper to moni-tor the traffic situation 240 @.Vehicles trav-elling ahead can thus be detected up to a distance of approximately 120 m.
The efficacy of the radar sensor can be impaired by contamination such as slush or snow. or by en-vironmental conditions such as heavy rain or spray. This means that the adaptive cruise control (ACC) also will not work. The instrument cluster display shows the message ACC: No distance con-trol ! . Clean the radar sensors as required
The adaptive cruise control (ACC) will automatical-ly be available again as soon as the radar sensors are no longer impaired. The message on the in-strument cluster display goes out. and the adaptive cruise control (ACC) can be reactivated.
A WARNING (Continued)
• Never ignore any illuminated warning lamps or text messages.
CD
Failure to observe illuminated indicator lamps and text messages can lead to your vehicle be-Ing damaged.
m When the adaptive cruise control (ACC) is L!..J switched on, some system-related displays on the instrument cluster can be overwritlen by other functions, e.g. incoming telephone calls. Strong reflected radiation of the radar signal, e.g. in multi-storey car parks, can impair the function of the adaptive cruise control (ACC).
The area in front of and around the radar sensor ® must not be covered by objects such as stick-ers, auxiliary headlights, face plates for number plates or the like, as this can impair the function of the adaptive cruise control (ACC).
Any structural modifications to the vehicle, e.g. lowering the vehicle or making alterations to the front end trim, can impair the function of the adap-tive cruise control (ACC). Structural modifications should therefore always be carried out by a quali-fied workshop. Volkswagen recommends using a Volkswagen dealership for this purpose.
Incorrectly performed repairs to the front end of the vehicle can alter the position of the radar sensor and therefore impair the function of the adaptive cruise control (ACC). Repair work should therefore only be carried out by a qualified workshop. Volks-wagen recommends using a Volkswagen dealer-ship for this purpose.
CD
Switch off the adaptive cruise control (ACC) If you suspect that the radar sensor has been damaged or is incorrectly positioned. This can help to prevent secondary damage. Have the radar sensor realigned.
• The radar sensor could be moved if it is hit, for example in parking manoeuvres. Readjust-Ing the sensor could impair the performance of the system or cause it to be switched off. 11>
