There are no buttons on the wiper lever in vehicles equipped with a multifunction steering wheel. The mullifunction display is controlled using the buttons on the multifunction steering wheel only.

m The service message will disappear after a W few seconds, when the engine is running, or when the (OKIRES!T) button on the wiper lever or the@ button on the mullifunction steering wheel is press-ed.
m If the vehicle battery is disconnected for long W periods in a vehicle with flexible oil change service, the system will not be able to calculate the lime when the next service is due. The service dis-plays could then display incorrect information. If this is the case then please observe the maximum service Intervals shown in =:o Booklet Service schedule. The scope and design of the menus in the instru-ment cluster display depends on the vehicle elec-tronics and the scope of vehicle equipment.
Qualified workshops can programme and modify other functions depending on the vehicle equip-ment level. Volkswagen Commercial Vehicles rec-ommends using a Volkswagen Commercial Vehi-cles dealership for this purpose.
Some menu options can only be opened when the vehicle is stationary.
If any priority 1 warning reports are being dis-played, you will be unable to open any menus. Some warnings can be confirmed and switched off with the@ button.

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

Automatic switch-off for electrical consumers
The intelligent vehicle electrical system automati-cally implements a range of measures to prevent the battery from discharging under high loads:
• The idling speed is increased so that the alter-nator provides more electricity.
• The performance of large electrical consumers may be reduced or they may be switched off com-pletely.
• The supply of electricity to the 12-volt sockets and the cigarette lighter is interrupted temporarily while the engine is being started.
The vehicle electrical system cannot always pre-vent the vehicle battery from discharging. For ex-ample, if the ignition is left on for an extended peri-od of time with the engine off, or if the parking light is left on when the vehicle is parked for an exten-ded period.
What can cause the vehicle battery to discharge?
• Long periods at a standstill in which the engine is not running, especially if the ignition is switched on.
• The use of electrical consumers when the en-gine is switched off.
• When the supplementary heater is in operation =>page 332.
A WARNING
Incorrectly attaching the battery and using In-correct vehicle batteries can cause short cir-cuits, fire and serious Injuries.
366 I Cleaning and maintenance
A WARNING (Continued)
• Always use maintenance-free and leak-proof batteries that have the same properties, specifications and dimensions as the factory-fitted vehicle battery.
A WARNING
A highly explosive mixture of gases Is given off when the vehicle battery is being charged.
• Vehicle batteries should only be charged in well-ventilated spaces.
• Never charge a vehicle battery once it has been frozen. Discharged vehicle batteries can even freeze at temperatures of around o•c (+32.FJ.
• The vehicle battery has to be replaced if it has ever been frozen.
• Incorrectly connected cables can cause a short circuit. First connect the positive cable and then the negative cable.
CD
• Never make or break connections between vehicle batteries if the ignition is switched on or the engine is running. Never use a vehicle battery that does not correspond with the vehi-cle's specifications. The vehicle's electrical system or electronic components could be damaged, which could lead to electrical faults, for example In the start/stop system.
• Never connect equipment that provides electricity, such as solar panels or a battery charger, to the 12-volt socket or to the cigarette lighter to charge the vehicle battery. This can damage the vehicle electrical system.
Dispose of the vehicle baltery as required by legislation. Batteries may contain toxic sub-stances such as sulphuric acid and lead.
Electrolyte can pollute the environment. Clean up any service fluid leakages and dis-pose of them property.
