Y Not enough windshield washer fluid. Refill windshield washer reservoir at the next
opportunity.

When the ignition is switched on, several warning and indicator lights come on briefly for a function
check. They go out after a few seconds.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.

NOTICE
To help prevent damage to the wiper blades and the wiper motor when it is cold outside, al-
ways make sure that blades are not frozen to the windshield before operating the wipers. Using
the service position can be helpful in cold weather so the wipers do not freeze to the wind-
shield.
x If the ignition is switched off while the wipers are running, the wipers will continue at the
same wiping speed when the ignition is switched on again. Frost, ice, snow, leaves, and other
objects on the windshield can damage the wipers and the wiper motor.
x Remove snow and ice from the wipers before you begin driving.
x If the wiper blades freeze to the windshield, loosen them carefully. Volkswagen recom-
mends using a deicing spray.
NOTICE
Never switch on the windshield wipers when the windshield is dry because the windshield can
be scratched.
The windshield wipers work only if the ignition is switched on and the engine hood is closed. The
windshield wipers turn off automatically when the engine hood is opened.
The intermittent wiping for the front windshield depends on the driving speed. The higher the
speed, the faster the wipers move.
If the wiper blades freeze to the windshield, loosen them carefully. Volkswagen recommends
using a deicing spray.
Windshield wiper functions

If there is something on the windshield, the wiper will try to wipe it away. If it continues to block
the wiper, the wiper will stop moving. Remove the obstacle and switch the wiper on again.

Rain sensor

Fig. 104 Inside the front windshield above the inside mirror: Sensitive rain sensor surface.

x Dirt: Caked-on dust, wax, any other buildup on the windshield (lotus effect), or car-wash detergent
residue can lower the rain sensor's sensitivity and cause it to react too slowly or not at all.
x Crack or chip in the windshield: If a stone hits and chips the windshield while the rain sensor is on,
this will trigger a wiper cycle. After that, the rain sensor will recognize the change and re-calibrate itself
to respond to the sensitive surface's reduced detection zone. Depending on the size of the chip, the
sensor's reaction pattern may or may not change.
WARNING
The rain sensor cannot always recognize rain and activate the wipers.
x Switch the wipers on manually when water on the windshield reduces visibility.
Clean the rain sensor's sensitive surface (arrow) regularly and check the wiper blades for wear or
damage.
To remove wax and coats of polish safely, we recommend using an alcohol-based windshield
cleaner.
Checking and refilling windshield washer fluid

Fig. 105 In the engine compartment: Cap of the windshield washer fluid reservoir.

Recommended cleaners
x For the warmer months, Windscreen Clear Summer G 052 184 A1 or equivalent. Mixing ratio 1:100
(1 part concentrate to 100 parts water) in the windshield washer reservoir.
x All-season Windscreen Clear G 052 164 A2 or equivalent. Mixing ratio in winter to 0 °F (-18 °C)
about 1:2 (1 part concentrate to 2 parts water), otherwise mixing ratio 1:4 in windshield washer reser-
voir.
Filling capacity
The windshield washer fluid reservoir holds about 1.2 gallons (4.5 liters).
WARNING
Never mix antifreeze or similar additives into the windshield washer reservoir. This could
produce an oily film on the windshield, which would considerably reduce visibility.
x Use clear water with a cleaning solution recommended by Volkswagen.
x If necessary, blend with a suitable windshield washer fluid antifreeze agent.
NOTICE
x Never mix cleaning solutions recommended by Volkswagen with other cleaning agents. If
you do, this could cause sediments or other by-products that can clog the windshield wiper
nozzles.
x When refilling, do not confuse one type of operating liquid with another! Otherwise serious
malfunctions and engine damage can occur!
