2009 AUDI Q7 wipers

The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR wil l also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i ] Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identica l tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and driving habits~& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads shou ld be checked by your autho ­
rized Audi dealer more often than specified in the
Warranty & Main­
tenance booklet.
Failure to have your brake pads inspected can
result in reduced brake performance.
On steep slopes, you shou ld use the braking effect of the engine .
This way, you prevent unnecessary wear on the brake system. If you
must use your brakes, do not hold the brakes down continuously.
Pump the brakes at intervals.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
Moisture
or road salt
If you are driving faster than 3 1 mph (50 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regular intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, will not notice anything.
Under certain conditions, for example, when driving through water
or very heavy rain, or even after washing your vehicle, the braking
effect can be reduced due to moisture (or in freezing conditions ice)
on the brake pads. A few careful brake applications sho uld dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced when the vehicle is driven on a salt -covered road and the brakes are not used. Here too,
you should clean off accumulated salt coating from brake discs and
pads with a few carefu l app lications of the brake ~& .
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is not driven regularly or
only for short trips with litt le use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
t he discs, it is advisable to clean off the pads and discs by braking
firm ly a few times from a moderately high speed~&.
Faults in the brake system
If you shou ld notice a sudden increase in brake peda l trave l, then
one of the two brake circuits may have failed~& .
Low brake fluid le vel
Malfunctions can occur in the brake system if the brake fluid level is
too low . The brake fluid level is monitored electronically .
Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi ­
tion of the brake pads through the openings in the wheel. If neces­
sary, the wheel may be removed for this inspection

Windows
Clear vision to all sides.
Clean all windows regularly to remove road film and
carwash wax buildup.
- Remove snow from windows using a brush.
- Use a plastic ice scraper to remove ice from windows and
mirrors.
- Remove other residue on the windows with a spray-on
glass cleaner.
- Wipe the windows dry with a clean piece of cloth or
kitchen paper towel.
The best way to remove snow from windows and mirrors is to use a
brush. Use a non-abrasive plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mirrors .
The windows must not be cleaned with insect remover or wax since
these can interfere with the function of the windshield wiper blades (chatter).
Oil, grease , or silicone residue can be removed with glass cleaner or
silicone remover. However, wax residue requires the use of a
specially formulated solvent. Please contact your authorized Audi
dealer for advice on safe products for wax removal.
Windows should also be cleaned on the inside at regular intervals.
Never dry windows with the same chamois that you use to dry
painted surfaces. Wax residue on the chamois can impair vision
through the windows .
& WARNING
• Always read and heed all WARNINGS and other information
=> page 312.
& WARNING (continued)
• The windshield must not be treated with water-repellent mate­
rials. They can increase glare under poor visibility conditions such
as wetness, darkness, or when the sun is low on the horizon. In
addition, they can cause the windshield wipers to chatter.
0 Note
• Never use warm or hot water to remove snow and ice from
windows and mirrors. This could cause the glass to crack.
• To prevent damage to the wires of the rear defogger, do not place
any adhesive stickers on the inside of the rear window over the
wires.
• To help prevent dirt from scratching the window, always scrape
in a forward direction -pushing the scraper away from you -never
back and forth .•
Weatherstrips
Complete car core includes the weatherstrips as well.
Apply a suitable rubber conditioner to the weatherstrips
from time to time.
To be able seal properly, the weatherstrips around the hood, doors,
rear lid, etc. must remain pliable. Spray the weatherstrips with sili ­
cone or coat them with talcum powder or glycerine to retain the
flexibility of the rubber and to protect them against freezing in the
winter.
& WARNING
Always read and heed all WARNINGS and other information

see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood. •
