2011 VOLKSWAGEN TRANSPORTER air condition

heavy load on the brakes should be avoided. For example, when driving too close to the vehicle ahead.
The rate of wear of the brake pads depends to a great extent on the conditions under which the ve-hicle is operated and the way in which the vehicle is driven. With regular urban trips, short journeys and a sporty driving style, the brake pads must be checked by a qualified workshop more regularly than stated in the service schedule.
When driving with wet brakes, for example after driving through water, after heavy rainfall or after washing the vehicle, the braking effect may be de-layed as the brake discs will be wet, or possibly ic-ed up (in winter). The brakes must be "dried" as quickly as possible by careful braking at higher speed. Ensure that no vehicle behind you or no other road user is put at risk as a result of this ac-
Any salt layer accumulating on the discs and pads will delay the braking effect and increase the braking distance. If the brakes on the vehicle have not been applied for a long time on roads that have been gritted with salt, the layer of salt must be re-duced through careful braking &.
Corrosion on the brake discs and dirt in the brake pads are facilitated through long periods of inactivi-ty, low mileage and low load levels. With inactivity or low use levels for the brake pads as well as cor-rosion, Volkswagen Commercial Vehicles recom-mends that the brake discs and brake pads be cleaned by braking strongly several times from high speed. Ensure that no vehicle behind you or no other road user is put at risk as a result of this
Fault in the brake system
A brake circuit may have failed if you have to re-duce speed and the vehicle does not brake as nor-mal (sudden increase in braking distance). This will be indicated by the warning lamp m and in some cases a text message. Go to the nearest qualified workshop immediately to have the fault corrected. Drive at low speed when doing this and anticipate much longer braking distances and an increase in the pressure required on the pedal.
Brake servo
The brake serve will only function when the engine is running and reinforces the pressure applied by the driver on the brake pedal.
If the brake serve is not functioning or the vehicle is being towed, the brake pedal will have to be de-pressed more forcefully as the braking distance will be increased due to the lack of assistance for the brake system &.
A 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.
• You must drive particularly carefully when driving with new brake pads In order to re-duce the risk of accidents, serious Injuries and loss of control of the vehicle.
• Never drive too close to other vehicles when running in new brake pads, and never create a driving situation that will place a heavy load on the brakes.
A WARNING
Overheated brakes reduce the braking effect and considerably Increase the braking dis-tance.
• When driving downhill the brakes are placed under particular strain and become hot very quickly.
• Before driving down a long, steep gradi-ent, reduce speed and change to a lower gear or move the selector lever to a lower position. This will make use of the engine braking ef-fect 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.
A 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 coat-Ing of Ice and salt with a few cautious appli-cations of the brake when visibility, weather, road and traffic conditions permit.
A WARNING
Driving without the brake servo can consider-ably Increase the braking distance and thus cause accidents and serious Injuries.
• Never allow the vehicle to roll if the engine Is switched off.
Starting the engine, changing gear and parking 273

The Automatic Post-Collision Braking System only functions in frontal, side and rear collisions if the airbag control unit registers the corresponding trig-gering threshold during the accident, and the acci-dent occurs at a speed greater than 10 km/h (6 m ph).
The ESC brakes the vehicle automatically, provi-ded that the hydraulic braking system, the ESC and the electrical system are undamaged in the accident and remain functional.
The following actions override automatic braking in the event of an accident:
• When the driver depresses the accelerator. No automatic braking occurs.
• When the brake pressure transmitted through the depressed brake pedal is greater than the brake pressure provided by the system. The vehi-cle is braked manually.
Anti-lock brake system (ABS)
The ABS prevents the wheels from locking when the brakes are applied up until the point where the vehicle is nearly stationary and assists the driver in steering the vehicle and keeping it under control. This means that the vehicle is less likely to spin, even when the brakes are depressed fully:
• Depress and hold the brake pedal with force. Do not take your foot off the brake pedal or reduce the force on the brake pedal.
• Do not pump the brake pedal or reduce the pressure on the brake pedal.
• Steer the vehicle while the brake pedal is fully depressed.
• The ABS will switch off when the brake pedal is released or if the pressure on the brake pedal is reduced.
If the ABS is taking corrective action, there is a pulsing movement in the brake pedal and some noise. However, ABS will not necessarily guaran-tee shorter braking distances in a// conditions. The braking distance could even be longer when brak-ing on gravel or on fresh snow covering an icy or slippery surface.
Brake Assist system (BAS)
The Brake Assist system can help to reduce the braking distance. The Brake Assist system reinfor-ces brake pressure when the driver depresses the brake pedal quickly in an emergency situation. As a result, full braking power is made accessible very quickly, braking power is reinforced and the brak-ing distance reduced. This means that the ABS is activated more quickly and more effectively.
Do not reduce the pressure on the brake pedal. The Brake Assist system will switch off the brake servo automatically when the brake pedal is re-leased or if the pressure on the brake pedal is re-duced.
Traction control system (TCS)
The TCS reduces the engine output if wheels pin occurs and adapts the output to suit road surface conditions. TCS helps the car to start moving, ac-celerate and climb gradients in unfavourable road conditions.
The TCS can be switched on and off manually 276.
Electronic differential lock (EDL)
The EDL is available for normal driving on straight roads. EDL brakes the wheel that has lost traction and distributes the driving force to the other drive wheels. To prevent the disc brake of the braked wheel from overheating, the EDL cuts out automat-ically if subjected to excessive loads. The EDL will switch on again automatically when the brake has cooled down.
A WARNING
Driving fast on icy, slippery or wet roads can lead to a loss of control of the vehicle and could cause serious injury to the driver and passengers.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic con-ditions. Do not Jet the extra safety afforded by the brake support systems ABS, BAS, EDL, TCS and ESC tempt you into taking any risks when driving.
• The Intelligent technology of the brake support systems cannot overcome the Jaws of physics or system-related vehicle limita-tions. Slippery and wet roads will remain dan-gerous, even when the ESC and other sys-tems are active.
• Driving too fast on wet roads can cause the wheels to Jose contact with the road sur-face and aquaplane. The vehicle cannot be braked, steered or controlled once it has lost contact with the road surface.
• Brake support systems cannot prevent an accident if, for example, you are driving too close to the vehicle in front or are driving too fast for the individual situation. .,.
Starting the engine, changing gear and parking 275

Changing gear earlier
In principle, the highest gear is always the most economical gear. A rule of thumb for most vehicles: at a speed of 30 kmlh (19 m ph} drive in third gear, at 40 km/h (25 mph) in 4th gear and at 50 km/h (31 mph) In 5th gear.
If the traffic and driving situation allows it, skipping gears when changing up a gear will also save fuel.
Do not drive gears to their upper limit. Use first gear only for pulling away then quickly change up to second gear. Avoid using the kickdown func-tion in vehicles with a DSG® dual clutch gearbox.
Vehicles with a gear display help to improve fuel economy by indicating the optimum time to change gear.
Rolling to a stop
Taking your foot off the accelerator will interrupt the supply of fuel to the engine and decrease fuel con-sumption.
Therefore, in situations such as approaching a red traffic light, let the vehicle roll without applying the accelerator.
Only press on the dutch pedal to disengage if the vehicle becomes too slow or if the stopping dis-tance is longer. The engine will then run at idling speed 263.
Switch off the engine in situations when the vehicle might be stationary for a long time, e.g. at a level crossing. In vehicles with an active start/stop sys-tem, the engine will switch off automatically when the vehicle Is stationary.
Thinking ahead when driving, and driving with the flow of traffic
Applying the brake and accelerator too often will significantly increase fuel consumption. If you think ahead when driving and maintain a sufficient dis-tance from the vehicle in front, simply keeping your foot off the accelerator should stop the speed from fluctuating. This means that active braking and ac-celerating is not always necessary.
Driving smoothly and evenly
Smoothness is even more important than speed. The more evenly you drive, the lower your fuel consumption will be.
When driving on a motorway, it is much more ef-fective to drive at a constant moderate speed than to drive with constant acceleration and braking. As a rule, driving with a constant style will get you to your destination just as quickly.
The cruise control system will help you to maintain a constant driving style.
Using additional equipment in moderation
lt is always important to be comfortable in your ve-hicle, but it is also important to consider the envi-ronment.
Some equipment will increase fuel consumption when switched on:
• The cooling function of the air conditioning sys-tem: if the air conditioning system is set to a very high or low temperature it will require a lot of ener-gy, which is generated by the engine. Therefore the temperature setting in the vehicle should not vary too much from the outside temperature. lt may be a good idea to air the vehicle before setting off and then to travel a short distance with the win-dows open. The air conditioning system should then be switched on once the windows have been closed. Keep the windows closed when driving at high speeds. Having the windows open increases fuel consumption.
• Switch the seat heating off as soon as it has served its purpose.
• Switch the windscreen and rear window heating off as soon as the windows have defogged and are clear of ice.
• Do not leave the supplementary heating system on when the vehicle is moving 332.
Other factors that Increase fuel consumption (examples):
• Fault in engine management.
• Driving in hilly regions.
• Driving with a trailer. Starting the engine, changing gear and parking I 279

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.

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.
