sistance if necessary.
If the engine coolant level is co rrect, then the
radiato r fan may be the cause of the malfunc­
tion.
If the . warning symbol (alternator ma l­
f u nction) a lso l ights up on the instr ument
panel ¢
page 31, then the fan belt may be
damaged .
A WARNING
- If your vehicle should break down for
mechanica l or other reasons, park at a
safe distance from moving traffic, turn off the engine and turn on the hazard
warning lights¢

engine cooling system -you co uld damage
your eng ine.
9=:7-Engine oil pressure malfunction
The red engine oil pressure warning symbol
requires immediate service or repair. Driving
with a low-oil -pressure indication is likely to
inflict severe damage to the engine.
If the . symbol appears in the display and
b links, the oil press ure is too low . An addition ­
a l dr iver message can also be disp layed by
press ing the
I CH ECKi button:
Switch off engine! Oil p ressure too low

gine oil level checks OK on t he dipstick,
do
not continue d riving and do not let the en­
gine run in idle .
Instead, contact your au­
thorized A udi dealer for assistance.
(D Tips
- The engine oil pressure symbol. is
not an indi cator for a low eng ine o il lev­
el. Do not rely on it . Instead, check the
oil level in your engine at regula r inter­
vals, preferably each time you refuel,
and always before going on a long trip .
- The yellow oil lev el warn ing indication

.,. When the indicator light
I.I switches off,
turn the ignition key to pos it ion @ but do
not press the accelerator pedal.
.. Re lease the ignition key once the engine
sta rts. The starter must not continue run­
ning.
A cold engine may sound loud after it has
been started . This is due to the hydraulic
va lves building up oil pressure. This is normal
and is not a need for concern.
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine about 30 seconds Later.
Glow plug system*
Diesel engines are equipped with a glow plug
system whose preheating t ime is controlled by the coo
lant and outs ide temperature . Start
the engine
immediately after the glow plug
indicator light
m sw itches off.
The glow plug indicator light will only illumi­
nate for approximate ly 1 second when the en­
gine is warm or the outside temperature is
higher than 46 °F (8 °C). That means you can
start the engine
immediately .
A WARNING
-Never start or let the engine run in a con-
fined or enclosed area. Exhaust fumes
from the engine contain carbon monoxide,
a colorless and odorless gas . Carbon mon­
oxide can be fatal if inhaled.
- Never leave the engine idling unattend­
ed. An unattended veh icle w ith a runn ing
engine poses a danger of personal injury
or theft .
(D Note
- Avo id high engine speeds, fast accelera­
tion or heavy engine loads while the en­ gine is still cold. This could damage the
eng ine .
- Th e engine cannot be started by pushing
or towing the vehicle .
@ For the sake of the environment
To avoid unnecessary engine wear and to
reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive
off immediately after starting your
vehicle. Maintain moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature.
· Stopping the engine
.,. Turn the ignition key to position @
¢page 106, fig . 120 .
A WARNING
-
-Never turn off the engine until the vehi-
cle has come to a complete stop.

-The brake booster and servotronic only
work when the engine is running. With
the ignition turned off, you have to apply
more force when steering or braking .
S ince you cannot steer and stop normal­
ly, this can lead to accidents and ser ious
injuries.
- The rad iator fan can continue to run for
up to 10 min utes even after you have
turned off the engine and removed the ign ition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build -up in the engine compartment.
«I) Note
Do not stop the engine immed iate ly after
hard or extended dr iving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up .

WARNING
Never allow the engine to run in confined
spaces -danger of asphyxiation .
(D Note
-Avo id h igh engine rpm, full thrott le and
heavy engine loads until the eng ine has

-Before descending a steep grade, reduce
speed and shift transmiss ion 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
brakes to get hot and dimin ish braking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not intend
to brake. Th is may cause the brakes to
overheat, prema ture wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced . In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct ­
ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est author ized Audi dealer or qualified
workshop .
Brake booster
The brake booster adds extra braking power.
The brake booster works with vacuum pres­
sure which is created only when the engine is
running¢ &,.
Int ellig ent technolog y 229
A WARNING
-Never let the veh icle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
example when towing your vehicle, or because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­
der braking.
T he ABS contributes effect ively to vehicle con­
trol s ince it preve nts the whee ls from
locking
when the brakes are applied. This means that
the vehicle remains steerable and is less likely
to skid .
With ABS y ou do not n eed to pump the
bra ke. Just h old t he br ake ped al d own .
However, do not expect the ABS to shorten
braking distance under
all circumstances.
When dr iving on g ravel or on new ly fallen
snow o n top of icy s urfaces, braking dis tance
may be even longer, therefore, under these
circumstances, it is especia lly important that
you drive s low ly and with great care.
How the ABS s ystem works
An a utomat ic check is made when a speed of
about 12 mph (20 km/h) is reached . When
th is happens, a pumping noise can be heard.
If an ind iv idual whee l begi ns to rotate too
s low ly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent that whee l from locking .
T his automatic adjustment p rocess will cause
a
sli ght vibrati on of the brake pedal and some
noises to a le rt you that ve hicle speed m ust be
adapted to existing road and traffic condi ­
tions. •

238 Driving off road
Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded for operation away
from paved roads. In situations where slip or a
differential locking function is required, the ESC offroad mode can be activated
c::> page 225 . Hill descent control is also availa­
ble in the ESC offroad mode, which automati­
cally brakes the vehicle and thereby keeps
speed constant when diffe rent wheel speeds
a re detected when descending a hill
c::> page 226. Your Audi also has permanent
a ll-wheel drive in addition.
H owever, your Aud i is not a pure off road vehi­
cle .
It was not built for d riving unde r extreme
conditions, e.g. fo r trips that are in the nature
of an expedition.
Dri ve only on road s and offroad section s
which mat ch the de sig n of your vehi cle and
y our a biliti es as a driver. Ne ver t ake ris k s!
Before driving offroad
- Check the eng ine oil level, tire pressure,
coolant level , and the fluid level in the w ind­
shield washe r reservo ir.
- Stow luggage items and other objects in the
luggage compartment, and secure them
against s lid ing aro und .
After driving offro ad
- After trips offroad, remove any twigs and
other foreign objects from the grill, the un­derbody and the wheels. Pay spec ia l atten­
t ion to fore ign objects (stones) which have
become lodged in the tire tread.
- Clean the body and the veh icle unders ide,
and inspec t the veh icle for poss ible damage.
- Clean dirty w indows , headlamp lenses , rear
l ights, and license plates .
- Perform a brake check (part icularly after
t ravel ling through water) .
A WARNING
-Drive especially attentively and plan
ahead in d iff icu lt road conditions and
when offroad. Excessive speed o r inco r­
rect maneuvers can cause injuries and
damage to the vehicle.
-
- Always adapt your speed and driving
style to road, offroad, t raff ic, and weath­
er cond itions. Drive especially slowly off­
road when you r view is res tricted.
- Please be awa re that in ESC off road
mode, particularly on a smoo th and s lip­
pery road, the wheels may have an in­
creased tendency to spin and the vehicle may break away -danger of skidding!
- Stability is limited in the ESC off road
mode .

268 Checking and filling
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
Changing the engine oil
The engine oil and oil filter must be changed
according to the m ileage (ki lometers) and
time intervals specified in your vehicle 's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter­
va ls is so very important because the lubricat ­
ing properties o f oi l decrease gradually during
normal vehicle use. If you are not sure when
you have your o il changed, ask your author­
i z ed Audi Service Advisor.
Under some ci rcumstances the engine oi l
should even be changed more frequently .
Change oi l more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your vehicle w here
temperatures stay below freez ing point for
l ong periods .
Detergent additives in the o il w ill make fresh
oil look dark after the engine has been run­
ni ng for a short time . This is normal and is not
a reason to change the oil more often than
recommended.
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00 (vehicles with gasoli ne engine) or
VW 507 00 (veh icles with diese l engine) . Your
Limited New Vehicle Warranty does not cover
damage or malf unctio ns due to failure to fol­
lo w recommended maintenance and use re­
quirements as set forth in the A udi Owner's
Manual and Warranty
& Maintenance booklet.
Your dea ler will have to deny warranty cover­
age unless you present to the dealer proof in
the form of Service or Repa ir Orders that all scheduled maintenance was
performed in a
timely manner.
Engine oil consumption
To provide effective lubrication and cooling for
internal engine parts, all internal combustion
engines use some o il. Oil consumption varies
from engine to engine and may change over
the life of the engine. Engines tend to use
more o il during the break-in period tha n they
do afterward, when oil consumption has sta­
bilized. Depending on the way the vehicle is
driven and the operating conditions, oil con­
s u mption can be up to 1 quart per 1,200
miles (1 liter per 2,000 km) . Consumption
may be higher within the first 3,000 m iles
(5,000 km) .
Under normal conditions, the rate of oil con­
sumption depends on oil quality as well as vis­
cosity, engine speed (rpm), outs ide tempera­
ture, road conditions, the amount of oil dilu­
t ion caused by condensed water or fue l resi­
due, and ox idat ion of the oil. Oil co nsumption
may increase with engine wear over time, un­
t il replacement of worn engine pa rts may be­
come necessary.
Because of all these variables, there is no
standard or "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 engine oil level. If the warn­
ing 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·
ately, check the engine oil level and add oil if
necessary. If the engine oil level is normal,
but the light continues to flash, do not keep
driving or let the engine idle, as damage may
occur .
II-

Coolant loss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized 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 overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to 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 ap­
plying light, downward pressure on the
top of the cap.
- To avoid being burned, do not spill anti­ freeze or coolant on the exhaust system
or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS c:;, A in Working in the engine compart­
ment on page 264.
Checking and filling 273
.. Turn off the engine .
.. Let the engine cool down.
.. Place a thick rag over the coolant expansion
tank
c:;, page 2 72, fig. 247 and carefully
twist the cap counter-clockwise c:;, &, .
.. Add coolant .
.. Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specificat ions
c:;, page 2 71, Coolant. We
recommend using only coolant additive G12+
+, G13 or in an emergency G12 +. 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 antifreeze
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 it to 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. .,.
