• To switch the rear axle differential lock on, press the 229 button on the dash panel at speeds under approximately 45 krnlh (28 mph) The indicator lamp r. lights up in the instru-ment cluster.
• 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.

ParkPilot

ParkPilot signal tones and displays . 290
The Park Pilot assists the driver when
parking and manoeuvring.
The ultrasound sensors in the bumpers transmit and receive ultrasound waves. The electronic sys-tem uses the ultrasound waves (i.e. transmission, reflection from the obstacle and reception) to cal-culate the distance between the bumper and the obstacle.

A WARNING
ParkPilot technology cannot overcome sys-tem-related vehicle limitations. The ParkPilot cannot replace the full concentration of the driver.
• Unintentional vehicle movements can cause serious injury.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic con-ditions.
• Ultrasound sensors have blind spots in which obstacles and people cannot be detec-ted.
• Always check the area around the vehicle as the ultrasound sensors will not always de-tect infants, animals and objects.
A WARNING (Continued)
• Certain surfaces of objects and clothes cannot reflect the signals from the ultrasound sensors. The system is unable to detect these objects or people wearing this type of clothing, or they may be detected incorrectly.
• External sources of sound can affect the signals of the ultrasound sensors. This may prevent the system from recognising people or objects.
CD
Various factors can negatively Impact the Park-Pilot functions or lead to damage to the vehicle and objects in the area surrounding the vehi-cle.
• The ultrasound sensors may not always be able to detect objects such as trailer drawbars, thin rails, fences, posts, trees and open or opening boot lids. This can result in damage to your vehicle.
• If the ParkPilot has detected an obstacle and issued a warning, the obstacle may move out of the detection range of the ultrasound sensors as the vehicle approaches it, particu-larly if the object is very high or very low. These objects are no longer registered.
• The vehicle can sustain considerable dam-age if the warning given by the ParkPiiot is ig-nored.
• Ultrasound sensors can be displaced or damaged through Impacts, e.g. when parking.
• The ultrasound sensors must be kept clean and free of ice and snow, and must not be cov-ered up by stickers or other objects, as this will prevent the system from working properly.
• Repainting the ultrasound sensors can im-pair the function of the Park Pilot.
• The ultrasound sensors should only be sprayed briefly when cleaning with pressure hoses and steam cleaners. The steam/hose nozzle must always be kept more than 10 cm away from the ultrasound sensors.
• Sources of noise can lead to errors in the ParkPilot system, e.g. rough asphalt, cobble-stones, induction loops, building equipment, or interference from other vehicles.

CD
• In some cases water and ice on the ultra-sound sensors could be registered as an ob-struction.
• Any equipment that has been retrofitted to the vehicle, e.g. bicycle carriers or number plate holders, can prevent the ParkPIIot from fu nctlonlng properly.
m Volkswagen Commercial Vehicles recom-L!J mends that drivers practise using the ParkPi-lot in a traffic-calmed area or car park to allow them to familiarise themselves with the system and its functions.

Switching ParkPilot on and off
m If an ultrasound sensor fails, the correspond-L!J ing area of the ultrasound sensor cluster is switched off and cannot be reactivated until the fault has been rectified (depending on the equip-ment level). Consult a qualified workshop in the event of a system fault. Volkswagen Commercial Vehicles recommends using a Volkswagen Com-mercial Vehicles dealership for this purpose. The Park Pilot uses ultrasound sensors to deter-mine the distance between the rear bumper and an obstacle. There are 4 ParkPilot ultrasound sensors in the rear bumper (arrows).

Failure to observe the illuminated text messag-es can lead to the vehicle being damaged. The areas to the front and rear of the vehicle that are scanned by ultrasound sensors are shown on the screen of the factory-fitted radio or navigation system. The positions of potential obstacles are displayed relative to the vehicle &.
The areas to the front (only with ParkPilot front and rear) and rear of the vehicle are fully scanned by the ultrasound sensors.
Acoustic signals and screen
Acoustic signals are given when the vehicle ap-proaches an obstacle located in the range of the ultrasound sensors. An intermittent signal tone is given if a sufficiently short distance between the vehicle and an obstacle is detected. The shorter the distance, the shorter the intervals. The signal tone will sound continuously if the obstacle is very close.
If you continue to drive the vehide closer to the ob-sta de despite the continuous signal tone, the sys-tem will no longer be able to measure the distance.
With some vehicle equipment levels the scanned areas may be displayed as several segments in a display. The closer the vehicle drives lowards an obstacle, the closer the segment will move to the vehicle in the display. The collision area has been reached when the penultimate segment is dis-played, if not before. Do not drive onl .,..

ing.
A camera in the tailgate 233 helps the driver when reverse parking or manoeuvring the vehicle. The camera picture and the orientation lines pro-jected by the system are displayed on the screen of the factory-fitted radio or navigation system.
The mute setting will be cancelled if the ParkPilot system is switched off and on again. Error warn-ings cannot be switched off.
If the ParkPilot display has been switched off man-ually and ParkPilot remains active, the mute set-ting is also cancelled.
A WARNING
Do not allow the Images shown on the screen to distract you from the traffic around you.
m it can take a few seconds for the acoustic or W optical signals to be given. The functions and displays of the rear view camera system may differ between vehicles, depending on whether or not they are fitted with ParkPilot.

Using the rear view camera system to esti-mate the distance from obstacles (people, ve-hicles etc.) Is Inaccurate and could cause ac-cidents and severe injuries. 11>
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.

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.
