Visual display in the exterior Situation mirror housing
The lane change assist system uses radar sensors to monitor the area behind the vehicle. The system then measures the distance and the difference in speed to other vehicles. The lane change assist system is activated at speeds over approximately 10 km/h (6 m ph) and deactivated at speeds under 5 km/h (3 mph). The driver receives infonmation via the visual display in the exterior mirror housing.
Visual display in the exterior mirror housing
The visual displays 248 in the exterior mirror housing notify the driver of following traffic on ei-ther side of the vehicle whenever a traffic situation is classified as critical when the driver intends to change lanes.
Tinted side windows or retrofitted tinting foils can negatively affect or distort the visual displays in the exterior mirror.

Radar sensors
The radar sensors are on the left and right behind the rear bumper and are not visible from outside. They monitor an area of approximately 70 metres behind the vehicle and the blind spots to the right and left of the vehicle. The monitored area to the side of the vehicle is approximately one lane wide.
The width of the lane is not detected in individual cases. but is predefined in the system. For this rea-son. incorrect displays could be shown when driv-

The following driving situations trigger a light in the exterior mirror 249 [ID (arrow) or 250 [ID (arrow):
• When another vehicle is overtaking your vehi-cle 249
• When overtaking another vehicle 250 with a speed difference of up to approximately 15 km/h (9 m ph). No display will be shown if the take-over manoeuvre is much faster.
The display in the exterior mirror will be shown ear-lier the faster you are nearing another vehicle as the lane change assist system calculates the
speed difference to other vehicles. For this reason, the display could be activated at different times de-spite your vehicle being at the same distance from other vehicles.
Physical and system-specific limits
The lane change assist system might, for example, interpret the traffic situation incorrectly in certain driving situations. In the following situations, for ex-ample:
• In tight bends.
• When road lanes are of varying width.
• At the brow of a hill.
• In poor weather conditions.
• Where there are special roadside structures, e.g. high or offset crash barriers. <1

r--('n First read and observe the Introductory Information and safety warnings&. on page 315.
The Driver Alert System determines the driving be-haviour at the beginning of a journey and uses it to evaluate the tiredness of the driver. This is com-pared to the behaviour of the driver while actually driving. If the system detects that the driver may be tired, an acoustic warning signal ("gong") will sound and an explanatory message or symbol (BREAK or =>Fig. 251) will appear in the instrument cluster display. The message on the instrument cluster display appears for about five seconds and may be repeated once. The last displayed mes-sage is saved by the system.
The message in the instrument cluster display can be switched off by pressing the (OK/RESIT I button on the wiper lever or the@ button on the multifunc-

A WARNING
The intelligent tyre monitoring system tech-nology cannot overcome the laws of physics, and functions only within the limits of the system. Incorrect handling of the wheels and tyres can lead to a sudden loss of pressure in the tyres, tread separation and even tyre blow-out.
• Check tyre pressures regularly and always maintain the specified tyre pressure value =>page 367. If the tyre pressure is too low, it is possible that the tyre temperature will in· crease to such an extent that the tread peels off and the tyre bursts.
• Always maintain correct cold tyre pres-sure as listed on the tyre pressure label =>page 367.
• Check tyre Inflation pressure regularly when the tyres are cold. Adjust tyre pressure in the cold tyre to the recommended tyre pressure for the tyres Installed on your vehi· cle as necessary.
• Check your tyres regularly for signs of wear or damage.
• Never exceed the top speed and load per-mitted for the fitted tyres.
CD
If valve caps are missing, the valve could be damaged. Always use valve caps that comply with the factory-fitted valve cap specifications. Always screw on valve caps fully. Do not use metal valve caps.
Indicator lamp
Under-inflated tyres will increase fuel con-W sumption and tyre wear. A higher tyre pres-sure generally reduces the fuel consumption. How-ever, the maximum tyre pressures specified by the manufacturer must always be adhered to.
m When new tyres are driven at high speeds for L!..J the first time, they can expand slightly and trigger a one-off pressure warning.
m Old tyres should only be replaced by tyres L!..J that have been approved by Volkswagen Commercial Vehicles for the vehicle type.
m Do not rely solely on the tyre monitoring sys-L!..J tern. Check your tyres regularly to ensure that they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blis-ters. Remove any objects that become embedded in the tyre tread but have not penetrated into the body of the tyre itself.
m The tyre monitoring system is adjusted for L!..J the factory-recommended tyre pressures to be found on the tyre pressure label. ro First read and observe the introductory Information and safety warnings & on page 318.

•I Indicator lamp flashes for around 1 minute and then lights continuously.
Several warning and indicator lamps will light up briefly as a functional check when the lgnilion is switched on. They will go out after a few seconds.
A WARNING
Differing tyre pressures or tyre pressures that are too low can cause tyre failure, the loss of vehicle control, accidents, serious in-jury and death.
• If the Indicator lamp (l) lights up, stop the vehicle as soon as possible and check all the tyres.
• Different tyre pressures or tyre pressures that are too low can Increase wear on the tyres, reduce vehicle stability and Increase the braking distance.
• Differing tyre pressures or tyre pressures that are too low can cause sudden tyre failure and lead to a tyre burst and the loss of con-trol over the vehicle.
• The driver Is responsible for the correct tyre pressure of all tyres on the vehicle. The recommended tyre pressure can be found on the tyre pressure label 367.
• The tyre monitoring system cannot func-tion correctly until all cold wheels have the correct tyre pressure.
• The use of Incorrect tyre pressures can cause accidents and tyre damage. All tyres must always have the correct tyre pressure to suit the vehicle load.
• Always Inflate all tyres to the correct tyre pressure before every journey.
• If driven with Insufficient pressure, the tyre flexes more. This could warm up the tyre to such an extent that the tread may separate and the tyre could burst.
• High speeds and overloading of the vehi-cle may cause the tyres to heat up to such an extent that the tyre bursts, leading you to lose control of the vehicle.

A WARNING (Continued)
• If the tyre pressure Is too low or too high, the tyres will wear prematurely and the vehl-cle will not handle well.
• If the tyre Is not flat and it Is not necessary to change the wheel immediately, drive at low speed to the nearest qualified workshop and check and correct the tyre pressure.
A WARNING
Failure to observe illuminated warning lamps and text messages can lead to your vehicle breaking down In traffic, and can cause acci-dent and serious injury.
• Never ignore any illuminated warning lamps or text messages.
• Stop the vehicle as soon as possible and when safe to do so.
CD
Failure to observe Illuminated Indicator lamps and text messages can lead to your vehicle be-Ing damaged.

m If a system fault is detected while the ignition L!..J is switched on, the yellow Indicator lamp flashes (l) for around one minute and then lights up steadily. A text notification may also be displayed.
m Driving on unpaved roads for a long time or a L!..J sporty driving style could temporarily deacti-vate the tyre monitoring system. The Indicator lamp shows the functional fault, but disappears if the road conditions or driving style change.

Function and control
Fig. 253 In the stowage compartment on the front passenger side: button for the tyre monitoring sys-tem.
l"'"""f'n First read and observe the Introductory l.-J,.:,LL Information and safety warnings & on page 318.
The tyre monitoring system uses data from the ASS sensors and other functions to check the speed of rotation and the rolling circumference of the individual wheels. The rolling circumference of the wheels changes, if the tyre pressure is too low. This is then shown by the tyre monitoring sys-tem ill in the instrument cluster.
The operation of the tyre monitoring system is im-paired:
• If the tyre pressure has been changed manual-ly.
• If the tyre has structural damage.
• If the vehicle Is loaded more heavily on one side.
• If the wheels on one axle are loaded more heavily, e.g. high load level.
• If snow chains have been fitted.
• If one wheel per axle has been changed.
• When driving with a heavy trailer attached.
• If you are driving under winter conditions or on unsurfaced roads.
• When driving fast with hard acceleration and braking manoeuvres.
Synchronising the tyre monitoring system
The tyre monitoring system will have to be re-synchronised after changing the tyre pressure, or after changing one or more wheels. This also ap-plies for changing the wheels, e.g. from the front to the rear, and for changing from summer tyres to winter tyres.
The saved values must be reset before the system can be resynchronised.
• Switch on the ignition, and while the vehicle is stationary
• Press and hold the =>Fig. 253 button until an acoustic confirmation signal is emitted.
• OR: with some vehicle equipment options, you can open menu option Tyre pressure in the in-strument cluster display and save the new tyre pressures there =>page 24.
Once the saved values have been reset, the sys-tem calibrates itself independently to the fitted tyres and the tyre pressures filled by the driver dur-ing normal vehicle operation. The calibrated values are adopted and monitored after a long journey at various speeds.
If the wheels are loaded more heavily than normal, e.g. if the vehicle is carrying heavy payload, the tyre pressure must be raised to the recommended full-load tyre pressure before synchronisation =>page 367.
m The tyre monitoring system stops working if l!.J there is a fault in the ESC or ASS =>page 269.
m When using snow chains, an incorrect dis-l!.J play may be shown as the snow chains in-crease the tyre circumference =>page 367. Driver assist systems I 321

• Exterior views 5
• Wipers/washer 116
• Supplementary heaters (auxiliary air heater or auxiliary coolant heater) 332
• Cleaning and caring for the vehicle exterior 380
A WARNING
Poor visibility through all windows increases the risk of collisions and accidents, which can cause serious injuries.
• Always ensure that all windows are free of ice, snow and mist to ensure good visibility.
3221 While driving
A WARNING (Continued)
• Maximum heat output, which Is needed to defrost the windows as quickly as possible, is only available when the engine has reached Its operating temperature. Do not start your journey until you have good visibil-Ity.
• Always ensure that the heating and fresh air system or the air conditioning system and the rear window heating are used correctly so that you have good visibility.
• Never use the air reclrculatlon mode for an extended period. If the cooling system Is switched off, the windows can mist up very quickly In air reclrculatlon mode and reduce visibility considerably.
• Always switch off the air reclrculatlon mode when it Is not required.
A WARNING
Stale air can quickly make the driver tired and affect their concentration, which In turn can cause collisions, accidents and serious Inju-ries.
• Never switch off the blowers or switch on the air recirculatlon mode for an extended pe· riod as this prevents fresh air from entering the vehicle interior.
• Switch off the air conditioning system if you suspect that it has been damaged. This can help to prevent secondary damage. The air conditioning system should be checked by a qualified workshop.
• Repairs to the air conditioning system re-quire specialist knowledge and special tools. Volkswagen Commercial Vehicles recommends using a Volkswagen Commercial Vehicles deal-ership for this purpose.
• Do not insert any objects in the slots of the air outlets. This could cause damage to the air outlets.
