2020 VOLKSWAGEN TRANSPORTER brake light

When the highest level is reached, the distance re-turns to the lowest level when the button is press-ed again.
The distance level can also be set using the Q or Q buttons on the multifunction steering wheel im-mediately after the(!) button on the multifunction steering Fig. 241 has been pressed.
Select the Settings menu, Assist systems submenu, ACC to set the distance to be used when the ACC is switched on 24.
Setting the gearbox programme
The acceleration response can be influenced by the gearbox programme selected. The programme can be set Using the ACC option in the Assistant submenu in the Settings menu. The following gearbox programmes can be selected:
• Normal
• Sport
• Eco
The following conditions can prevent the adaptive cruise control (ACC) from reacting:
• If the accelerator is depressed.
• If no gear is selected.
• If the ESC is taking corrective action.
• If there is a fault in several brake lights on the vehicle or on a trailer with an electrical connection to the vehicle.
• If the vehicle is reversing.
• System version 1: if the vehicle is travelling faster than approximately 160 km/h (1 00 m ph).
• System version 2: if the vehicle is travelling faster than approximately 210 km/h (130 mph).
A WARNING
If you do not maintain the minimum distance to a vehicle In front and the difference In speed between the two vehicles is so great that the braking action of the adaptive cruise control (ACC) is insufficient, you are In dan-ger of colliding with the vehicle in front. You should reduce the vehicle speed immediately with the foot brake.
• The adaptive cruise control (ACC) may not be able to detect all driving situations cor-rectly.
• Leaving your foot on the accelerator means that the adaptive cruise control (ACC) will not brake automatically. This is because manual acceleration overrides the system.
• You should always be prepared to brake the vehicle yourself.
• Observe country-specific regulations re-garding the minimum distance.
m The set speed will be deleted if the ignition or L!.J the adaptive cruise control (ACC) is switched off.
m The adaptive cruise control (ACC) is auto-L!.J matically deactivated when the traction con-trol system (TCS) is deactivated.
m In vehicles with a start/stop system, the en-L!.J gine is switched off automatically during the stationary phase of adaptive cruise control (ACC) and is then restarted for moving off. Switch off the adaptive cruise control (ACC) temporarily in the following
situations
1""111 First read and observe the introductory L-J,:.IJ Information and safety warnings & on page 298.
The adaptive cruise control (ACC) should be switched off in the following situations due to sys-tem limitations &:
304 I While driving
• When turning off roads, driving around round-abouts, narrow curves, joining motorways, exiting from motorways or driving through road works, to prevent the vehicle from unnecessarily accelerat-ing to the set speed in these situations
• When driving through a tunnel as this situation could impair the system function.
• On roads with more than one lane, if other vehi-cles are driving more slowly in the fast lane. The slower vehicles In the other lane would be overtak-en from the right side in this case.
• In heavy rain, snow or spray as vehicles travel-ling ahead cannot be monitored sufficiently or maybe cannot be monitored at all. .,.

Acceleration can be stopped at any time by de-pressing the brake pedal or pressing the(@ or @ button on the multifunction steering wheel 302.
When driving through bends
While driving through bends, the radar sensor may sometimes lose the vehicle travelling ahead or may react to a vehicle in the next lane 242 !Al. In such situations, the vehicle might decelerate unnecessarily or not react to the vehicle in front. In this case the driver must override the adaptive cruise control (ACC) by depressing the accelerator, or interrupt the braking procedure by depressing the brake pedal or pressing or @ button on the multifunction steering wheel 302.
Driving in tunnels
The radar sensor function may be restricted in tun-nels. Switch off the adaptive cruise control (ACC) in tunnels.
Narrow vehicles and a zig-zag traffic situation
Narrow vehicles and vehicles travelling slightly to the left or right of your vehicle will only be recog-nised by the radar sensor once they have entered the radar range 242@ This applies in par-ticular to narrow vehicles such as motorbikes. If re-quired, brake the vehicle yourself.
Vehicles with special load or special equipment
Any load or accessories on other vehicles that pro-trude from the side, rear or over the roof of the ve-hicle may not be detected by the adaptive cruise control (ACC) .
Switch off the adaptive cruise control (ACC) when the vehicle ahead has special load or special equipment, or while overtaking vehicles of this kind. If required. brake the vehicle yourself.
When other vehicles change lanes
Vehicles that are very close when they move into your lane can only be detected by the radar sen-sors when they have moved into the sensor range. This means that the adaptive cruise control (ACC) may have a delayed reaction =>Fig. 243@]. If re-quired, brake the vehicle yourself.
Stationary vehicles
The adaptive cruise control (ACC) does not detect stationary objects during a journey, e.g. stationary traffic or a vehicle that has broken down.
306 I While driving
If a stationary vehicle is hidden behind a vehicle that has been detected by the adaptive cruise con-trol (ACC) and this vehicle turns off the road or changes lane, the adaptive cruise control (ACC) will not be able to react to the stationary vehicle 243 [Q]. If required, brake the vehicle your-self.
Oncoming vehicles and vehicles crossing your path
The adaptive cruise control (ACC) does not react to approaching vehicles or vehicles crossing your path.
Metal objects
Metal objects, such as tracks in the road or metal plates used in roadworks, can confuse the radar sensor and cause incorrect reactions from the adaptive cruise control (ACC) .
Possible radar sensor function impairments
The adaptive cruise control (ACC) will switch off temporarily if the radar sensor function is impaired, e.g. due to heavy rain, spray, snow, ice or mud. A corresponding message will appear on the instru-ment cluster display. 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.
Strong reflected radiation of the radar signal, e.g. in multi-storey car parks, can impair the function of the radar sensor.
Towing a trailer
The adaptive cruise control (ACC) operates with reduced dynamics when the vehicle is towing a trailer.
Overheated brakes
If the brakes overheat, e.g. following heavy braking or when driving down steep inclines for long peri-ods, the adaptive cruise control (ACC) may be de-activated temporarily. A corresponding message will appear on the instrument cluster display. lt is then not possible to activate the adaptive cruise control (ACC).
As soon as the temperature of the brakes has de-creased sufficiently, the adaptive cruise control (ACC) can be activated again. The message on the instrument cluster display goes out. If the mes-sage ACC not ava i 1 able does not go out for a long time, there is a fault. Go to a qualified work-shop. Volkswagen recommends using a Volkswa-gen dealership for this purpose.

System limits
r-('n First read and observe the Introductory L-J,:.U Information and safety warnings & on page 307.
The area monitoring system (Front Assist) has physical and system-related limits. The driver may therefore feel that, in certain circumstances, some Front Assist reactions occur unexpectedly or with a delay. You should therefore always be prepared to take full control of the vehicle if necessary.
The following conditions can prevent Front Assist from reacting, or cause a delay in its reaction:
• In tight bends.
• If the accelerator is fully depressed.
• If Front Assist is switched off or there is a fault.
• If TCS or ESC is switched off manually.
• If the ESC is taking corrective action.
• If there is a fault in several brake lights on the vehicle or on a trailer with an electrical connection to the vehicle.
• If the radar sensor is dirty or covered.
• If the vehicle is reversing.
• Under hard acceleration.
• In snow or heavy rain.
• In case of narrow vehicles, e.g. motorbikes.
• If vehicles are travelling slightly to the left or right of your vehicle.
• If vehicles are crossing in front of your vehicle.
• If there is oncoming traffic.
• In uncertain traffic situations.
• 1/Vhen loads or attachment parts on other vehi-cles protrude to the side, rear or above the normal dimensions of the vehicle. Lane change assist system (Side Assist)

Washing the vehicle
r-f'n First read and observe the introductory Information and safety warnings & on page 380.
The longer substances such as insects, bird drop-pings, resinous tree sap, road dirt, industrial de-posits, tar, soot or road salt and other corrosive materials remain on the vehicle, the more damage they do to the paintwork. High temperatures (for in-stance in strong sunlight) accelerate the corrosion process. The underside of the vehicle should also be cleaned thoroughly and regularly.
Car washes
Please observe the signs on the automatic car wash. Before using an automatic car wash take the usual precautions, such as closing all windows and folding in the exterior mirrors, in order to avoid damage to the vehicle. You must consult the car wash operator if there are special parts on your ve-hicle such as spoilers, roof luggage carrier systems or radio aerials ::.CD.
The paint is so hard-wearing that the car can nor-mally be washed without problems in an automatic car wash. However, the effect on the paint de-pends to a large extent on the design of the car wash. Volkswagen Commercial Vehicles recom-mends the use of car washes without brushes.
To remove any wax residue from the windows and to stop wipers rubbing, please note the following points ::.page 382, Cleaning windows and exterior mirrors.
Washing the car by hand
When washing by hand, first soften the dirt with plenty of water and rinse off as well as possible.
Then clean the vehicle with a soft sponge, a glove or a brush using only light pressure. Start with the roof and work from the top to the bottom. Use a shampoo for very stubborn dirt only.
The sponge or glove should be wrung out thor-oughly at regular intervals.
Clean the wheels, sill panels etc. last. Use a differ-ent sponge for this purpose.
A WARNING
Parts of the vehicle with sharp edges can cause Injury.
• Protect your hands and arms from cuts on sharp parts, for example when cleaning the underbody or the inside of the wheel hous-lngs.
A WARNING
After the car has been washed, the braking effect could set in later than normal and ex-tend the braking distance as the brake discs and brake pads will be wet, or iced up In win-ter.
• You can "dry and de-ice" the brakes by performing careful braking manoeuvres. Make sure that you do not endanger any oth-er road users or violate any legal regulations when doing so.
CD
• The water should be no warmer than +so•c (+140.FJ.
• Do not wash the vehicle in direct sunlight in order to avoid damage to the vehicle palntwork.
• Never clean with insect sponges, rough kitchen sponges or similar products as these can damage the surface.
• Never clean the headlights with a dry cloth or sponge. Always use a wet cloth or sponge. lt is best to use soapy water.
• Washing the vehicle In cold weather: if the vehicle is rinsed with a hose, do not direct the water at the lock cylinders or the gaps around the doors, boot, or bonnet. The locks and seals could freeze.
CD
Observe the following guidelines before driving the vehicle into an automatic car wash in order to avoid damage to the vehicle:
• Ensure that the gap between the guide rails In the car wash is sufficient for the vehicle track. If the track is too narrow your wheels and tyres will be damaged.
• Switch off the rain sensor before driving the vehicle Into an automatic car wash.
• Check that the car wash is tall and wide enough for your vehicle.
• Fold In the exterior mirrors. Electrically fold-Ing exterior mirrors must be moved electrically. Do not fold them in and out by hand.
• In order to prevent damage to the palntwork on the bonnet, fold the wipers back onto the windscreen after drying the wiper blades. Do not drop the wipers onto the glass.
• Lock the tailgate to prevent it from opening accidentally In the car wash. Vehicle care and maintenance 381

Washing the vehicle with a high-pressure cleaner
I""""'T'n First read and observe the Introductory L.-lo:oJ.I information and safety warnings & on page 380.
Follow the instructions provided by the manufactur-er when cleaning your vehicle using a high-pres-sure cleaner. This applies in particular to the pres-sure and the spraying distance=>&.
Maintain sufficient distance to soft materials such as rubber hoses, insulation, and the ParkPilot sen-sors. The ParkPilot sensors are located in the front bumper, and in some cases also in the rear bump-er => Never use concentrated jet nozzles or dirt blast-ers=>&.
A WARNING
The incorrect use of a high-pressure cleaner can cause visible and invisible long-term damage to tyres and other materials. This can cause accidents and serious injuries.
• Maintain sufficient distance between the washer jet and the tyres.
• Never clean the tyres with concentrated jet nozzles (dirt blasters). The tyres may incur visible and invisible damage even if cleaned briefly with the spray at a distance.
A WARNING
After the car has been washed, the braking effect could set in later than normal and ex-tend the braking distance as the brake discs and brake pads will be wet, or iced up in win-ter.
• You can "dry and de-ice" the brakes by performing careful braking manoeuvres. Make sure that you do not endanger any oth-er road users or violate any legal regulations when doing so.
CD
• The water may be no warmer than +so·c (+140.FJ.
• Do not wash the vehicle In direct sunlight In order to avoid damage to the vehicle palntwork.
• The ParkPilot sensors In the bumpers must be kept clean and free of Ice. When cleaning with pressure hoses or steam cleaners, the sensors should only be sprayed briefly and the steam/hose nozzle must be kept more than 10 cm away.
• Do not clean windows that are iced over or covered In snow with a high-pressure cleaner.
• Washing the vehicle in cold weather: If the vehicle is rinsed with a hose, do not direct the water Into the lock cylinders or the gaps round the doors, boot, or bonnet. The locks and seals could freeze. Cleaning windows and exterior mirrors

4121 If and when
When the hazard warning lights are switched on, for example if the vehicle is being towed, a change in direction or lane change can still be indicated by operating the turn signal. The warning lights will be interrupted temporarily.
Switch on the hazard warning lights:
• When traffic ahead suddenly starts moving more slowly or you reach the tail end of a traffic jam, to will warn vehicles behind you.
• When there is an emergency.
• When the vehicle breaks down.
• When the vehicle is being towed.
Always follow local regulations for the use of the hazard warning lights.
If the hazard warning lights are not working, use an alternative method of drawing attention to the bro-ken-down vehicle. This method must comply with traffic legislation.
A WARNING
Ignoring any of the items on this important safety checklist can lead to accidents and se-vere Injuries.
• Always follow the Instructions In the checklist and observe the general safety pro-cedures.
A wARNING
The components of the exhaust system be-come very hot. This can cause fires and seri-ous Injuries.
• Park the vehicle so that no part of the ex-haust system can come Into contact with any Inflammable material underneath the vehicle, e.g. dry grass, fuel.
m The vehicle battery will discharge if the haz-L.:!J ard warning lights are left on over a long peri-od of time -even when the Ignition is switched off.
m If you brake hard at speeds over approxi-L.:!J mately 60 km/h (37 mph), the brake lights will flash to warn the traffic behind. If you then continue to brake, the hazard warning lights will be switched on automatically at speeds under approximately 10 km/h (6 mph). The brake light will light up stead-Ily. Once the vehicle starts to accelerate, the haz-ard warning lights will switch off again.
