& WARNING (continued)
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant
escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
=> page 290, "Engine compartment".
0 Note
Do not continue driving if the_¥_ symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine. •
Engine oil pressure malfunction 't:::f:
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to inflict severe damage to the
engine.
If the ~ symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also be
displayed by pressing the
[CHECK] button :
Switch off engine! Oil pressure too low
Immediate actions
- Pull off the road.
- Stop the vehicle.
- Turn off the engine .

Dipstick readings checks too low
- Top off oil to the proper level=> page 306 .
Make sure that the oil pressure warning symbol~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the oil pressure warning symbol ~ starts flashing
again even though the engine oil level checks OK on the
dipstick,
do not continue driving and do not let the
engine run in idle.
Instead, contact your authorized Audi
dealer for assistance.
[I) Tips
• The engine oil pressure symbol~ is not an indicator for a low
engine oil level. Do not rely on it. Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip.
• The yellow oil level warning indication
~ requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning ~ starts to flash before you respond to the low oil
level warning
..'!' . By then, your engine may already have suffered
serious damage. •

in. WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road u sers must not b e put at r isk - you may cau se an ac cident!
• Before d esc ending a steep gr ade , redu ce speed and shift tran s­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brake s to get hot and diminish braking efficiency.
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake. Thi s may caus e the brakes to overheat ,
premature wear and increa sed stopping di stance.
• Under certain climatic and operating conditions such as
pas sing through water, driving 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 , disc s and drums .
Carefully apply brakes for a test. Brake s will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt -cov ered roads
without using your brakes can al so affect braking efficiency. Clean
off accumulated salt coating from brake d iscs and pads with a few
careful brake applications.
• If you damage the front spoiler , or if you install a different
s poiler , be sure the air flow to the front brakes is not obstructed.
Otherwise the 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 increased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop. •
Brake booster
The brake booster adds e xtra brakin g pow er .
The brake booster works with vacuum pressure which is created only
w hen the en gine is ru nning =>& .
in. WARNING
• Never let the vehicle roll to a stop with the engine shut off .
• If the brake booster i s not working , for example when towing
your vehicle , or because the brake booster has somehow been
damaged , the brake pedal must be p ressed considerably harder to
make up for the lack of booster assistan ce.
Functioning of Anti-Lock Brake System
(ABS)
AB S prevents the wheels from locki ng up under braking.
T he ABS co ntribu tes effectively to vehicle co ntrol s ince it prevents t he
w hee ls from
locking when the b rakes are a pplied. This means t hat t he
veh icle rema ins steerable and is less likely to s kid .
W ith ABS you do not need to
pump the brake. Just hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance u nder
oil
circums tances. When driving on grave l or on newly fa llen snow on top
of icy su rfaces, braking dis tance may be even longer, therefore, under
these c irc umstances, it is especially important that you dr ive slowly
and w it h great care .
How the ABS system works
An automatic check is made when a speed of about 12 mph (20 km/h)
is reached . Whe n this happens, a p umping noise can be hea rd. ._

Audi oil standard VW 502 00 (vehicles with gaso line e ngine) or VW
507 00 (vehicles w it h die sel eng ine).
Changing the engine oil
The eng ine oil and oil fi lter mus t be changed according to the mileage
(kilome ters) and t ime intervals specified i n your vehicle 's Warranty &
Ma intenance booklet . Do not exceed these interva ls - harmful
deposi ts from o ld engi ne oil can reduce engine pe rfo rmance and ca n
lead to expensive engine repa irs.
C hangi ng the oil at the recommende d interva ls is so very imp ortant
because the lubricating properties of o il decrease gradually during
normal ve hicl e use. If yo u ar e not sure w hen you have yo ur oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the eng ine o il should even be changed
more fr eq uent ly. Chang e oil mor e of ten if you d rive mostly short
distances, operate the veh icle in d usty areas or mostly under stop­
and -go t raff ic condi tion s, or when you use yo ur vehicle where tempe r­
atures stay be low free zing po int for long periods.

Damage or malfunctions due to lack of maintenance
It is essentia l that you change your o il at the recommended intervals
using only en gine oil th at com plies wi th A udi o il st and ard VW 502 0 0
(vehicles w ith gasoline eng ine) o r VW 507 00 (vehicles with d iesel

Engine oil consumption
To provide effective lubr ication a nd cooling for interna l eng ine parts,
a ll in ter na l c omb ustion e ngines use some oil. Oil cons umption v aries
from engine to engine and may change over the life of the eng ine .
E ngines te nd to use m ore oi l dur ing the b re a k-i n period t han t hey do
after ward, when oil consumption has stab ilized. Depending on t he
way the vehicle is driven and the operatin g cond itions, oi l cons ump ­
tion ca n be up to 1 qua rt pe r 1,200 m iles
(I liter per 2 ,000 km).
Consumption may be higher withi n th e first 3,0 00 miles (5,00 0 km).
Under nor mal co ndi tions, the rate o f oi l consu mptio n depe nds o n oil
quality as well as viscosity, engine speed ( rpm), o utside tempe rature,
roa d condi tion s, the amou nt of o il d ilution caused by co nde nsed
water or fu el residue, and oxidation of the oil. O il cons umption may
increase wi th en gine we ar ove r time, un til repl aceme nt of worn
eng ine pa rts may become necessa ry.
Because of all these var ia bles, there is no standa rd o r "norma l" rate
of oil consumption .
We urge you to check the engine oil level at
regular intervals, preferably every time you fill the fuel tank, and
always before a long trip .
The oil pressure warning light
~ is not an indicator of low eng ine
oil level. If the warning light does not go out after starting, or
flashes while driving (above 1500 rpm), a buzzer will sound . It
indicates that the oil pressure is too low. Stop the engine immedi- _.,,

-We recommend using only coolant additive Gl2 ++ (check the
l a bel) for yo ur vehicle. This coolant ad dit ive is available at au tho·
r ized Audi dealers . Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
eng ine coo lant . Adding radiator repa ir fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant Level
The engine coolant level can be checked with a quick
glance .
Fig. 2 37 En gin e
c o mpar tmen t: C oolant
ex pansion tank
Before you c heck anything in the eng ine compartment,
always read and heed all WARNINGS~ & in "Working in
the e ngine compartment" on
page 301.
- Turn off the ignit ion .
- Let t he eng ine cool down .
- Place a thick rag over the coolant expans ion tank
~ fig . 237 and carefully twist the cap counter ·clockwise
~ & -
Vehicle OP-eration
-Read the engine coolant level in th e open coo lant expan ·
sion tank ~ fig . 2 3 7 . With a cold engine, th e coolant level
should be between the "min" and "max" ma rkings . Whe n
the engine is warm , the level may be slight ly above the
"max" marking .
The location o f the coo lant expans ion tank can be seen in the engine
compartment illustration=>
page 302 .
To obt ain an accurate reading , the engine must be sw itched off.
Th e expans ion t an k in your vehicle is equippe d with an electric coolant
level sensor.
When the coolant lev el is too low, the warning light in the Auto·Check
System=>
page 35 will blink until you add coolant and t he level has
been resto red to normal. Even though there is an electric coolant
level sensor, we st ill recommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system . In the event of
coo lant loss , the cooling system sho uld be inspected immed iate ly by
your authorized Aud i dea ler . It is not enough mere ly to add coolant.
In a
s ealed system, losses can oc cu r only if the boiling point of the
coolant is exceeded as a result of ove rheating .
& WARNING
The cooling system is under pressure and can get ve ry hot. Reduce
the ri sk of scalding from hot coolant by following the se steps.
• Turn off the engine and allow it to cool down .
• Protect your face, hand s and arms from e scaping fluid and
s team b y co ve ring the cap with a large, thi ck r ag.
• Turn the cap slowly and ver y carefully in a counter-clockwise
direction whil e applying light , downward pre ssure on the top of
thecap .
