16 Instrum ent s and w arn ing /indic ato r light s
-If the brake warning/indicator light does
not go out after a few seconds and the
park ing brake is released, or lights up
wh ile you are driving, the fluid level in
the brake fluid reservoir is too low .
If you
believe that it is safe to do so, proceed
immediately at low speed to the nearest
authori zed Aud i dealer o r qualified repa ir
f acili ty and have the brake system in­
spected.
- Always keep in m ind that after several
brake applicat ions, yo u will need greater
pressure on the brake peda l to stop your
vehicle. Do not re ly on strained brakes to
respond with maxim um stopp ing power
in critical situations. You must allow for
increased brak ing distances . The extra
distance used up by fad ing brakes could
lead to an acc ident.
PARK/( ®) Electromechanical parking brake
The warning/indicator light monitors the
electromechanical parking brake.
If the indicator light . (USA models)/ .
(Canada models) turns on, the park ing brake
was set .
• (U SA models) • (Canada models ) Cau­
tion: Vehicle pa rked too steep
If the indicator light blinks and the message
appears, there is not eno ugh braking power to
keep the vehicle from ro lling . The brakes have
overheated. The vehicle could ro ll away even
on a small incline.

Note the information on c::> page 81, Start­
Stop-Sys tem.
A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiation .
- Never turn off the eng ine unti l the vehi­
cle has come to a complete stop .
- The brake booster and power steer ing
only work when the engine is running .
If
the engine is off, you have to use more
force when steering or braking. Because
you cannot stee r and brake as you usua l­
ly wou ld, this could lead to crashes and
ser ious injur ies.
- Avoid high engine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating temperat ure - ot her­
wise yo u risk eng ine dam age.
- The eng ine ca nnot be started by pushing
or tow ing the veh icle.
(D Tips
- After a cold engine is sta rted, there may
be a brief period of increased noise be ­
ca use oil p ress ure mus t fi rs t bu ild up in
the hyd raulic valve adjus ters. This is nor ­
mal and not a ca use for concern .
-If yo u leave the vehicle with t he ignit ion
switched on, the ignition will switch off
On th e ro ad 77
after a cer tain per iod of t ime. Please
note that electrical eq uipment such as
exterior lights will sw itch off as well
when that happens.
Stopping the engine
"' Bring your vehicle to a complete stop.
"' Move the selector lever to the P or N posi ­
tion .
"' Press the

and open the d river's door . The locked steer­
ing helps prevent vehicle theft.
Eme rgency off
If necessa ry, the engine can be switched off
with the selector lever in the R or D/S posi ­
t ion . The engine stops if you press the
I S TART ENG INE STOPI button at speeds below
6 mph (10 km/h) .
A WARNING
-Never tur n off the engine unti l the vehi ­
cle has come to a complete stop .
- T he b rake booster and powe r stee ring
only work w he n the eng ine is r unning. If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usual­
ly would, th is co uld lead to crashes and
serio us injuries.
- For safety reasons, you sho uld a lways
park your vehicle w ith the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away .
- After the eng ine has been switched off,
the radiator fa n can cont inue to run for
up to 10 minutes - even with the ignition

thori zed Audi dea le r.
Closing the engine hood
.,. Pull the hood down un til the pressure from
t he struts is reduced.
.,. Let the hood
drop down and latch in p lace .
Do not try to push it shut; it may fail to en­
gage ¢&_ .
A WARNING
-
A hood that is not completely latched
could fly up and b lock your view while dr iv­
ing.
- When you close the engine hood, check it
to make sure the safety catch has p roper­
ly engaged. The hood sho uld be flush
with the surrou nding vehicle body pa rts.
- If you notice while driv ing t hat the hood
is not s ecured prope rly, stop at onc e and
close it.

-Always dispose of used engine oil proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open streams or down
sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­
tects the engine from freezing in the winter.
The cooling system is sealed and generally re­
quires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not
need to be changed . The coolant consists of a
mixture of specially conditioned water and the
manufacturer 's glycol-based coolant addi-
tive G13 antifreeze with anticorrosion addi­
tives (50% for USA models; 60% for Canadian
models) . This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling.
It also raises the boil­
ing point of the coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien ­
cy .
If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system.
For year -round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distill ed water is recommended .
Checking and filling 231
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~&.
in Working in the engine
compartment on page 225.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in­
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G12++ or G13 (check the label)
for your vehicle. This coolant additive is
available at authorized Audi dealers.
Other types of antifreeze can signifi­
cantly reduce corrosion protection. The
resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly 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.

expansion tank

232 Check ing and filling
Before you check anything in the engine com­
partment,
a lways r ea d and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 225.
• Park your vehicle on a level surface.
• Switch
off the ignition .
• Read the eng ine coolant leve l from the cool­
ant expansion tank
c> fig. 196, c> page 22 7,
fig. 193. With a cold eng ine, the coolant
level should be between the "min" and
"max" markings. When the engine is warm,
the leve l may be slightly above the "max"
ma rk ing.
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration ¢
page 22 7.
To obtain an accurate reading, the engine
must be sw itched
off.
The expans ion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System ¢ page l 6 will
i l luminate unti l yo u add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time .
Coolant loss
Coolant loss may indicate a lea k in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your author ized Audi dealer. It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
T he cooling system is unde r pr essure and
c an get ve ry hot. Reduce t he risk of s cald­
ing from hot coolant by followi ng these
steps .
- T urn
off the engine and allow it to cool
dow n. -
Protect your face, han ds and arms from
escaping flu id and steam by cover ing the
cap with a large, thick rag.
- Tu rn the cap slowly and very care fully in
a counte r-clockwise direct ion while ap­
plying lig ht, downward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine par ts. Under certa in cond i­
tions, th e ethylen e glyco l in engine coo l­
a nt can catch fire.
(D Note
Do not add a ny type o f radiator leak sea l­
ant to your veh icle's engine coolant. Add­
i ng radiator r epa ir fluid may adv erse ly af­
fe ct the funct io n and perfo rma nce of you r
co oling syste m and could result in damage
not covered by your New Veh icle Limi ted
War ran ty.
Adding coolant
Be very careful when adding engine coolant.
Befo re you check anyth ing in the eng ine com­
partment,

We recommend using only coolant addi-
tive
Gl2++, Gl3 or in an emergency Gl2+. Do
not use a different additive. In an emergency
use plain water until you can get the correct
additive and can restore the correct ratio. This
should be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add cold antifree ze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot.
A WARNING
-The cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
-Turn off the engine and allow itto cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spill an ­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Do not add coolant if the expansion tank
is empty. Air could enter the cooling sys­
tem and damage the engine. If this is
Checking and filling 233
the case, do not continue driving. Seek
professional assistance .
- Coolant pollutes the environment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze
c> page 231 must be re­
stored as soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operating conditions .
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off.
It can even switch
on again later by itself
c> .&, if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.
