Get Lights and Vision -> Rain/light sensor Guide for Volkswagen Transporter Van Seventh Generation (2021-2025)

Rain/light sensor

Fig. 1 On the right of the steering column: wiper lever.

Switch for setting the sensitivity of the rain and light sensor.

The rain/light sensor is deactivated.

The rain/light sensor is active, automatic wipe when necessary.

When the rain/light sensor is activated, it automatically controls the frequency of the wiper intervals, depending on

the intensity of the rain.

Activating and deactivating the rain/light sensor

1. Push the lever to the desired position→ Fig. 1.

The automatic wipe function can be activated and deactivated in the vehicle settings in the Infotainment system

(→ Vehicle settings menu).

If the automatic wipe function is deactivated in the Infotainment system, the intervals are set at fixed levels.

Adjusting the sensitivity of the rain/light sensor

The sensitivity of the rain and light sensor can be adjusted manually using the switch in the wiper lever→ Fig. 1

→

1. High sensitivity – set the switch to the right.

Low sensitivity – set the switch to the left.

WARNING

The rain/light sensor cannot always detect every rain shower and activate the wipers.

● If necessary, switch on the wipers manually if the water on the windscreen restricts the field of vision.

Troubleshooting

Washer fluid level too low

The indicator lamp lights up yellow.

Fill up the washer fluid reservoir as soon as possible (→ Washer fluid).

Fault in wipers

The indicator lamp lights up yellow.

The wipers do not wipe.

1. Switch the ignition on and off.

2. If the fault persists, go to a correspondingly qualified workshop.

Fault in rain and light sensor

The wipers are not switched on automatically if it rains during rain/light sensor operation.

1. Switch the ignition on and off.

2. If the fault persists, go to a correspondingly qualified workshop.

Changes in the response of the rain and light sensor

Possible causes for faults and misinterpretationsrelating to the sensitive surface of the rain and light sensor (→ Front

view) include:

—Damaged wiper blades: a film of water or smears caused by damaged wiper blades can increase the time the

wipers are switched on, can shorten the length of the intervals between wipes or cause the wipers to run

continuously.

—Insects: insects hitting the windscreen surface can cause the wipers to be activated.

—Salt deposits: in winter, salt deposits can cause the wipers to continue to wipe the windscreen when it is almost

dry.

—Dirt: dry dust, wax, windscreen coatings(lotus effect), or detergent deposits (from an automatic car wash)can

cause the rain/light sensor to become less sensitive and react later or too slowly, or prevent it from reacting at all.

Clean the sensitive surface of the rain and light sensor at regular intervals and inspect the wiper blades for damage

(→ Vehicle care, exterior).

—Crack in the windscreen:a wash cycle will be triggered if the rain/light sensor is on when the windscreen is

impacted by a stone. The rain/light sensor will then register the reduction in sensitivity of the surfaces and adjust

accordingly. Depending on the size of the stone impact, the response of the rain/light sensor may change.

We recommend that you use an alcohol-based glass cleaner to remove wax and polish.

The wipers will try to wipe away any obstacles that are on the window. The wipers will stop moving if the

obstacle blocks their path. Remove the obstacle and switch the wipers back on again.

Introduction

You can use the exterior mirrors and the interior mirror to observe traffic behind you and adjust driving style

accordingly.

For safety reasons, it is important that the driver positions the exterior and interior mirrors correctly before starting a

journey →

Looking in the exterior mirrors and the interior mirror does not allow the driver to see the entire area around the side

and rear of the vehicle. The area that cannot be seen is known as the blind spot. Objects and other road users may

also be located in the blind spot.

WARNING

Adjusting the exterior and interior mirrors while driving may cause the driver to become distracted. This can lead to

accidents and serious injuries.

● Adjust the exterior mirror and interior mirror only when the vehicle is stationary.

● When parking, changing lane, or performing an overtaking or turning manoeuvre, always pay careful attention to

the area around the vehicle as objects and other road users may be located in the blind spot.

● Always ensure that the mirrors are positioned correctly and that the rear view is not restricted by ice, snow,

condensation or any other objects.

WARNING

If you estimate the distance from traffic behind you incorrectly, you can cause accidents and serious injuries.

● Curved mirrors (convex or aspheric) enlarge the field of vision and can make objects in the mirror seem smaller

and further away than they actually are.

● Using curved mirrors to estimate the distance from other vehicles behind you when changing lanes can provide

inaccurate results and can lead to accidents and severe injuries.

● Whenever possible, use the interior mirror to check the exact distance between your vehicle and following traffic

or other objects.

● Make sure that you have a good view to the rear of the vehicle.

WARNING

Automatic anti-dazzle mirrors contain an electrolyte fluid which could leak if the mirror is broken.

● The leaking electrolyte fluid can cause irritation to the skin, eyes and respiratory organs, especially in people who

suffer from asthma or similar illnesses. Immediately ensure that there is a sufficient supply of fresh air and get

out of the vehicle. If this is not possible, open all of the windows and doors.

● If your eyes or skin come into contact with the electrolyte fluid, wash the affected area immediately with plenty

of water for at least 15 minutes and seek medical attention.

● If your shoes or clothes come into contact with the electrolyte liquid, wash them immediately with plenty of

water for at least 15 minutes. Clean shoes and clothes thoroughly before wearing them again.

● If you have swallowed electrolyte fluid, rinse your mouth immediately with plenty of water for at least 15

minutes. Do not induce vomiting unless instructed to do so by a doctor. Seek medical assistance immediately.

NOTICE

If the glass of an automatic anti-dazzle mirror is broken, electrolyte fluid can leak from the mirror. This fluid

corrodes plastic surfaces.

● Remove leaked liquid as quickly as possible, e.g. with a wet sponge.
