avoid sudden , hard brake applications.
• Canada model s: If the brake warning light(@ and the ABS

first under hard braking. Rear wheel lock-up can cau se lo ss of
veh icle cont rol and an accident . Have your vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop.
Drive slow ly and avoid sudden, hard brake applications .
• If the brake warning/indicator light doe s not go out after a few
seconds and the parking brake released, or lights up while you are
driving , the fluid level in the brake fluid rese rvoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the neare st authorized Audi dealer or qualified repair facility
and have the brake system inspected .
• Always keep in mind that after several brake applications , you
will need greater pressure on th e brake pedal to stop your vehicle .
Do not rely on strained brakes to respond with maximum stopping
power in critical situation s. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident . •

© -Clean the windshield. To eliminate water droplets, the wind­
shield wiper performs one afterwipe operation after several seconds
while driving. You can switch this function off by moving the lever to
posit ion© within 10 seconds of the afterwipe operation. The after­
wipe function is reactivated the next time the ignition is switched on.
Cleaning the headlights*. The headlight washer system* only func­
tions when the light is switched on. The headlights are automat ically
cleaned the first time and every fifth time the lever is moved to posi­

& WARNING
• The rain sensor is only intended to assist the driver . The driver
is still responsible for manually switching the wipers on according
to the visibility conditions.
• The windshield may not be treated with water-repelling wind­
shield coating agent s. Unfavorable conditions, such as wetness,
darkness, low sun, can result in increased glare. Wiper blade
chatter is also possible.
• Properly functioning windshield wiper blades are required for
a clear view and safe driving=>
page 67, "Replacing windshield
wiper blades" .
0 Note
• In the case of frost, check whether the windshield wiper blades are
frozen to the windshie ld . Switching on the windshield wipers can
damage the wiper blades!
• Prior to using a car wash, the windshield wiper system must be
switched off (lever in position 0). This helps to prevent unintentional
switching on and damage to the windshield wiper system .
[I] Tips
• The w indshield wipe rs are switched off when the ignition is turned
off . Activate the windshield wipers after the ignition is switched back
on by mov ing the windshield w iper lever to any position.
• Worn or dirty windshield wiper blades result in streaking. This can
affect the rain sensor* function. Check your windshie ld wiper blades
regularly.
• The rain sensor* is part of the interval wiping system . Turning off
the ignition will a lso deactivate the rain sensor*. To reactivate the
sensor, switch off the interval wiping function, then switch it back on
again .
• The washer fluid nozzles of the w indshield washer system are
heated at low temperatures when the ignition is on .
• When stopping temporarily, e.g. at a traffic light, the set speed of
the windshield wipers is automatically reduced by one speed .•
