light VOLKSWAGEN T-ROC 2020 Service Manual

Lock the vehicle from the outside.
Automatic switch-off of side lights and parking lights
If the battery capacity is not sufficient for the side lights or parking light to remain switched on for
two hours, the 12-volt vehicle battery can be discharged to such an extent that it is no longer
possible to start the engine
In the case of standing times of more than two hours, the vehicle will detect a weak 12-volt vehicle
battery and switch off the side lights or parking light so that the engine can still be started.

WARNING
Accidents and serious injuries can occur if the vehicle is parked without sufficient illumination, as
other road users might have difficulty seeing the vehicle, or may not see it at all.
Always park the vehicle safely and with sufficient lighting. Observe any applicable local regulations.
If the vehicle lighting is required for several hours, switch on the right or left parking light if possible.
The illumination time of the parking light on one side is generally twice as long as for continuous
parking light on both sides of the vehicle.

Dynamic headlight range control
The headlight range cannot be adjusted manually if the vehicle has dynamic headlight range control.
The headlight range is automatically adapted to suit the vehicle load level as soon as the headlights
are switched on

WARNING
Heavy objects in the vehicle can cause the headlights to dazzle and distract other road users. This
could lead to accidents and serious injuries.
The light cone should always be adjusted to the load level of the vehicle to ensure that other road
users are not dazzled.

WARNING
Failure or a malfunction of the dynamic headlight range control can cause the headlights to dazzle or
distract other road users. This could lead to accidents and serious injuries.
The headlight range control should be checked by a qualified workshop as soon as possible.

If you have to drive a right-hand drive vehicle in a left-hand drive country, or vice versa, the
asymmetric dipped beam headlights may dazzle oncoming traffic. The headlights must therefore be
switched over when you travel to these countries.
With some equipment levels, the headlight alignment can be adjusted in the Infotainment system in
the Vehicle settings menu Infotainment system controls and displays
In vehicles in which the headlights cannot be switched over in the menu, masking stickers should be
applied to certain parts of the headlight lenses, or the headlights should be adjusted by a qualified
workshop. A qualified workshop can provide you with further information. Volkswagen recommends
using a Volkswagen dealership for this purpose.

Travel mode may be used only for a short period. Please contact a qualified workshop for a
permanent conversion. Volkswagen recommends using a Volkswagen dealership for this purpose.
Interior lighting
Instrument and switch lighting
The brightness of the instrument and switch lighting can be adjusted in the Infotainment system in
the Vehicle settings menu Infotainment system controls and displays
The brightness setting is automatically adjusted to the changing light conditions in the vehicle.
When the light switch is in position , a sensor will switch the dipped beam and the lighting in
the instruments and switches on and off automatically depending on the ambient brightness level.

When the light is switched off and the ignition switched on, the instrument and switch lighting
(needles and scales) is switched on. As the ambient light becomes lower, the illumination of the
scales is automatically reduced and may be switched off entirely. This function is intended to remind
the driver to switch on the dipped beam in good time, i.e. when driving through tunnels.
Interior and reading lights
Press the appropriate button or move the switch to the appropriate position:
Switch off the interior light.Switch on the interior lights.The interior lights are switched on
automatically when the vehicle is unlocked, a door is opened or the vehicle key is removed from the
ignition.Switch the reading light on or off.
Stowage compartment and luggage compartment lights
A light will be switched on and off when the stowage compartment on the front passenger side or
the boot lid is opened or closed.
Background lighting

pending on the equipment level, the background lighting provides indirect light in various areas of
the vehicle interior.
The front footwell may also be illuminated.
The brightness of the background lighting can be adjusted in the Infotainment system in the Vehicle
settings menu Infotainment system controls and displays

The lights go out when the vehicle is locked or after a delay of a few minutes when the vehicle key is
removed from the ignition lock. This prevents the 12-volt vehicle battery from discharging.

WARNING
Without an adequate amount of anti-freeze, the washer fluid can freeze on the windscreen and
obscure your view.
In winter temperatures, use the windscreen washer system only when adequate anti-freeze has
been added to the washer fluid.
Never use the windscreen washer system at winter temperatures before the windscreen has been
heated by the ventilation system. The anti-freeze mixture may otherwise freeze on the windscreen
and restrict vision.

WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of accidents and serious injuries.
Always change wiper blades if they are damaged or worn and no longer clean the windows properly
Wiper blades

NOTICE

to the windscreen, the wiper blades and the wiper motor:
The wiper lever is located in the basic position.
Snow and ice have been removed from the wiper blades and door windows.
Wiper blades that have become frozen onto the glass have been carefully loosened. Volkswagen
recommends using a de-icer spray for this.

NOTICE
Do not switch on the wipers when the window is dry. Using the wipers when the window is dry can
damage the glass.

When switched on, the wipers will temporarily be switched to the next setting down when the
vehicle is stationary.

When parking the vehicle in cold weather, it may be helpful to leave the front windscreen wipers in
the service position to make it easier to loosen the wiper blades Wiper blades

Switch the ignition off and on.
If the problem persists, go to a qualified workshop.
Changes in the activation behaviour of the rain/light sensor
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain/light
sensor
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 quickly and continuously.
Insects: insects hitting the windscreen 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 too slowly, or prevent it
from reacting at all. Clean the sensitive surface of the rain/light sensor Caring for and cleaning the
vehicle exteriorat regular intervals and inspect the wiper blades for damage.
Crack in the windscreen: a wipe 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 impairment of the
sensitive surfaces and adjust accordingly. Depending on the size of the stone impact, the activation
behaviour of the rain/light sensor may be changed.
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 wiper will stop moving if
the obstacle continues to block its path. Remove the obstacle and switch the wiper back on again.
