Warning and indicator lamps
A WARNING
The intelligent technology of the pull-away assist systems cannot overcome the laws of physics or system-related vehicle limitations. Never let the extra convenience afforded by pull-away assist systems tempt you into tak-ing any risks when driving-this can cause accidents.
• Unintentional vehicle movements can cause serious Injury.
• The pull-away assist systems cannot re-place the driver's full concentration.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic con-ditions.
• Pull-away assist systems cannot hold the vehicle in all hill start situations or brake it sufficiently on all slopes going downhill (e.g. if the ground is slippery or icy). m First read and observe the introductory information and safety warnings & on page 282.

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.

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.

m If there is a function fault in the ParkPilot, an W acoustic warning is emitted for approximately 3 seconds when switched on for the first time. The ParkPilot should be checked by a qualified work-shop immediately. ParkPilot front and rear

Driver assist systems I 291

A WARNING (Continued)
• The camera lens enlarges and distorts the field of vision and the objects on the screen will not be depicted as precisely and accu-rately as they are In reality.
• Certain objects, for example narrow posts or railings, may be difficult or Impossible to see on the screen because of its low resolu-tion or poor light conditions.
• The rear view camera system has blind spots within which obstacles and people can-not be detected.
• Keep the camera lens clean, free of snow and Ice and do not cover it.
A WARNING
The Intelligent rear view camera system tech-nology cannot overcome the laws of physics, and functions only within the limits of the system. Careless or unintentional use of the rear view camera system can cause accl· dents and lead to serious Injury. The system is not a substitute for the full concentration of the driver.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic con· ditions.
General information
r'""'('n First read and observe the Introductory L-J,::.U information and safety warnings & on page 291.
Requirements for parking and manoeuvring while using the rear view camera system
Checklist
./ The tailgate must be closed.
./ The camera must give a clear and accurate image, i.e. there must be good visibility and the camera lens must be clean =:o Fig. 233.
./ There must be a clear and unobstructed view of the area behind the vehicle.
./ The rear of the vehicle must not be heavily loaded.
2921 While driving
A WARNING (ConUnued)
• Keep looking In the direction In which you are parking and at the relevant area sur-rounding the vehicle. The front of the vehicle swings out more than the rear of the vehicle.
• Do not allow the Images shown on the screen to distract you from the traffic around you.
• Always monitor the area around the vehi· cle as small children, animals and objects will not always be detected by the rear view cam-era system.
• The rear view camera system may not be able to display all areas clearly.
• The rear view camera system should only be used when the tallgate is fully closed.
CD
• The rear view camera system shows only two-dimensional images on the screen. The lack of depth of field means that potholes and protruding objects on the ground may only be detected with difficulty, or may not be detected at all.
• The rear view camera system may notal· ways be able to detect objects such as thin rails, fences, posts, trees etc. This could result In damage to your vehicle. ./ The driver must be familiar with the system.
./ The vehicle must be undamaged. The rear view camera system must be checked by a qualified workshop if the position or angle of the camera has changed, e.g. following a rear impact.
Volkswagen Commercial Vehicles recommends that you practise parking with the reversing camera in a traffic-calmed area or car park with good visi-bility and weather conditions, so that you can famil· iarise yourself with the system, orientation lines and guiding functions in a safer environment.
Rear view camera system settings
Various settings, including brightness, contrast and colour, can be by touching the relevant function buttons 1j or G. or by moving the corre-sponding slider.
• Stop the vehicle in a safe place.
• Apply the handbrake firmly.
• Switch on the ignition.

The cruise control system (CCS) is able to main-tain an individual set speed at forward speeds be-tween approx. 30 km/h (19 mph) and 180 km/h (112 mph).
The CCS slows the vehicle only by easing off the accelerator, not by actively braking. The CCS can-not maintain a constant speed when travelling downhill. The vehicle speed can Increase under its own weight. Shift down gear and brake the vehicle using the foot brake &.
Additional information and warnings:
• Changing gear 260
• Accessories, modifications, repairs and renewal of parts '*page 394
A WARNING
The use of the cruise control system (CCS) can lead to accidents and serious Injuries if traffic does not allow you to drive at a safe distance from the vehicle In front at a con-stant speed.
