& WA RNING (conti nu ed )
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
pa ssing through water, dr iving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter ,
ice can accumulate on the brake pads , linings , discs and drums .
Carefully apply brakes for a te st. Brakes will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can al so affect br aking efficiency. Clean
off accumulated salt coating from brake disc s and pads with a few
careful brake applic ations.
• If you damage the front spoiler , or if you in stall a different
spoile r, be sure the air flow to the front brakes is not obstructed.
Otherwi se th e brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an inc reased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop .

Brake booster
T h e brake booste r adds ext ra braking p ower.
The brake booster works with vacuum pressure which is created on ly
w hen the eng ine is ru nnin g=>&.
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake boo ster i s not working , for example when towing
your veh icle , or because the brake booster has somehow been
& W ARNING (continued )
damaged , the brake pedal must be p ressed considerably harder to
make up for the la ck of booster assi stan ce. •
Functioning of Anti-Lock Brake System
{ABS)
ABS prevents the wheels from l ockin g up under br aking.
Th e ABS contr ibutes effectively to vehicle co ntrol s ince it prevents t he
w heels from
locking when the brakes are applied . This means that the
veh icle rema ins steerable and is less likely to skid .
With ABS you do not need to pump the brake. Just hold the brake
pedal down .
However, do no t expect that the ABS shortens bra king d istance under
all circumstances . When dr iv ing on grave l or on newly falle n snow on
top of icy s urfaces, braking d istance may be even longer, therefo re,
under these circumstances, it is especially important that yo u drive
slowly and with g re at c are.
How the ABS system works
An au tomatic c hec k is made when a speed of about 4 mp h (6 km/ h) is
reached. When t his happens, a pump ing noise can be heard.
If an ind ivi dual wheel begi ns to rot ate too s low ly in relat ion to ve hicle
speed and tends to loc k, t he ABS automatically reduces brake pres­
s ur e to p revent t hat wheel from lo cking.
T hi s au tomatic adjustment p rocess w ill cause a
s light vibration of
the bra ke pedal and some noises to a lert you that vehicle speed must
be adapted to ex isting road and traffic co nditions .
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving ...

speed acco rding to the road and traffic conditions. Do not let the
e xtra safety afforded by th e ABS tempt you into taking extra risk s.
The ABS cannot overcome the laws of physics .
[ i J Tips
• If ABS is not funct ioning properly, a warning light will come on .
See ~
page 16 .
• If a fault occurs in the ABS, the EDL is also not functioning. This is
ind ic at ed by t he A BS w arni ng light. •
Brake assistant
The broke assistant is designed to achieve the optimum
br oking effect.
Th e b rake ass istant he lps to inc rease t he effective brak ing powe r and
thus to ac hieve a shorter stopping distance.
If the driver presses the
bra ke ped al ve ry qu ickly, the b rake assistant au toma tically bo osts the
brak ing force to the max imum level, up to the point where the anti­
lo ck brak e function (ABS) in tervenes to stop the whee ls from l ocking.
You should then keep the brake pedal pressed unti l the vehicle has
bra ke d to t he require d spee d. T he bra ke ass istan t swi tches itse lf off
as soon as you re lease the b rake pedal.
Th e brake assistant will not be operative if there is a ma lfu nctio n in
t he A BS .
& WARNING
Please remember that the accident risk always increases if you
drive too fast , especially in corners or on a slippery road , or if you
follow th e vehicle ahead of you too closely. An increased accident
risk cannot be compensated even by the brake assistant, so always
maintain a safe speed .•

- Have someone place chocks under both the vehicle and the
trailer wheels.
- With chocks in place, slowly release the brakes until wheel
blocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake.
- Place an automatic transmission in
P, respectively a
manual transmission in first or reverse gear.
When restarting after parking:
- Start the engine .
- Shift transmission into gear .
- Release the parking brake and slowly pull out and away from the wheel blocks .
- Stop and have someone retrieve the wheel blocks.
[I] Tips

IJIII Cleaning and protection
-----=---=------------------------------
carpets and floor mats, since other fabric surfaces could be harmed
by brushes.
Normal surface sta ins can be cleaned using a commercially available
foam cleaner. Spread the foam on the surface of the fabric with a soft
sponge and work it in gently. Do not saturate the fabr ic. Then pat the
foam dry using absorbent, dry cloths (e.g. microfiber cloth) and
vacuum it after it has dried comp lete ly.
Cleaning stains
Stains caused by beverages (e .g. coffee, fruit juice, etc.) can be
treated with a mild detergent solut ion. Apply the detergent solution
w ith a sponge. In the case of stubbo rn stains, a detergent paste can
be applied directly to the stain and worked into the fabric. After­
wa rds, use copious amounts of clean water to remove the remaining
detergent. Apply the water with a damp cloth or sponge and pat the
fabric dry with an absorbent, dry cloth .
Sta ins from chocolate or makeup should have detergent paste (e .g.
ox-gall soap) rubbed into them . Afterwards, remove the soap with
water (damp sponge).
Alcohol can be used to treat stains from grease, oil, lipstick or a ball­ point pen. Melted grease or dye must be patted off using absorbent
material. It may be necessary to retreat the areas with detergent
paste and water.
In the case of genera l soiling of t he upholstery and cover mater ia l, we
recommend hiring a specialist that has the equipment to clean the
seat covers and other fab ric surfaces by shampooing and spray
extraction.
& WARNING
Always read and heed all WARNINGS and the information
=> page 206.
W Tips
Open Velcro fasteners on your clothing can damage the seat cover.
Please make sure that Velcro fasteners are closed .•
Plastic parts and instrument panel
- Always use a clean cloth moistened in clear water.
Always use a clean cloth moistened in clear water to clean these
areas. For persistent dirt use an A udi approved
solvent-free plastic
cleaner/protectant .
& WARNING

________________________________________________ T_ i_ re _ s_ a_ n_d_ w_ h_ e_ e_l _s _ ........
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that ill uminates a low tire pres­
sure telltale when one or more of your tires is signif icantly under­
inflated . Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated
ti re causes the tire to overheat and can lead to tire fa ilure. Unde r­
inf lation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
illumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS malfunction ind i­
cator to indicate when the system is not operating properly. The
TPMS malfunction indicator is combined w ith the low tire pressure
telltale . When the system detects a malfunction, the telltale will
flash for approximate ly one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle
start -ups as long as the malfunction exists.
When the ma lfunction indicator is illum inated, the system may not
be able to detect or signa l low tire pressure as intended. TPMS
ma lfunctions may occur for a var iety of reaso ns, includ ing the instal­
lation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on
yo ur vehicle to ensure that the replacement or alternate tires and
wheels allow t he TPMS to continue to funct io n properly .•
