Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) * and fully load­
ed veh icles.
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any h igher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
- Vehicle components such as the eng ine,
transmission, suspension or e lectrical
system can be severely damaged by driv­
ing thro ugh water.
- Always switch
off the Start-Stop-System
when driving through water¢
page 79 .
@ Tips
-Check the depth o f the wate r before driv ­
ing through it.
- Do not s top the veh icle, dr ive i n reverse
or switc h the engine off when driving
through water.
- Keep in mind that oncom ing vehicles
may create waves that raise the water
l eve l and make it too deep for you r vehi­
cle to drive through safely .
-
Dri vin g and en vironm ent 201
- Avo id driving through salt wate r because
it can cause corrosion .
Catalytic converter
Applies to vehicles: w ith gasoline engine
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
... Always use lead-free gasoline ¢ page 214,
Fuel supply.
... Never run the tank down all the way to emp­
ty.
.,. Never put too much motor o il in your engine
¢ page 226, Adding engine oil~-
... Never try to push- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean­
up" dev ice bui lt into the exhaust system of
the ve hicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be­
fore they are re leased into the atmosphere .
The exclusive use of unleaded fuel is c ritically
important for the life of the ca talyt ic convert­
er and proper f unct ion ing of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after s topping
the engine.
- Never touch the exhaust tail pipes once
they have become hot . This cou ld result
in burns .
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.

-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch :
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical ha zards c:::> & .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition ,
certain fluids contained in vehicles and

tain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm .
Checking and filling 223
-Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age to vehicle systems will occur.
(® For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly . If
you see spots from oil or other vehicle flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer.
Closing the engine hood
.,. Pull the hood down until the pressure from
the struts is reduced.
.,. Let the hood
drop down and latch in place.
Do not try to push it shut; it may fail to en­
gage
c:::> ,A .
A WARNING
-
A hood that is not completely latched
could fly up and block your view while driv ­
ing .
- When you close the engine hood, check it
to make sure the safety catch has proper­ ly engaged. The hood should be flush
with the surrounding vehicle body parts.
- If you notice while driving that the hood
is not secured properly , stop at once and
close it. •

226 Checking and filling
@ Tips
-The oil pres sure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead , check the oil level in
your engine at regular intervals, pref­
erably each t ime you refuel, and always
before going on a long trip.
- If you have the impression your engine
consumes excessive amounts of oil, we
r ecommend that you consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time. Your Audi dealer has in ­
str uctions about how to measure oil con­
sumption accurately.
Checking the engine oil level

Add engine oil if the bar of the oil level indi­
cator is near "min" ~
page 226 .
Depending on the way the veh icle is driven
and the operating conditions, oil consumption
can be up to 1/2 quart per 600 m iles (0.5 liter
per 1,000 km) . Consumption may be higher
within the f irst 3,000 miles (5,000 km).
(D Tips
The oil leve l indicator in t he MMI Display is
on ly an information display. If the oil level
i s low, a min imum oil warn ing appears in
the instrument cluster. Add oil

-While topping off, the oil must not come
in contact with hot e ngine parts -fire
hazard!
- The oil filler cap must be properly se­
cured to prevent oil from being sprayed
on the hot engine and exhaust system
when the engine is running -fire hazard! ..,_

228 Check ing and filling
- Always dispose of used engine oil proper ­
l y . Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- 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
qu ires 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 spec ially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with ant icorros ion 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 coo ling system from
corrosion and scaling . It also raises the boil­
ing point of the coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water.
The
p ropo rtion of coolant add itive must be at
l e a st 50 % but not mo re th an 60 %
to ma in­
tain antifreeze protection and cooling efficien­
cy . If the coolant frost protect ion is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and eng ine cool ing system.
For year-round driving, antifreeze is added at
the facto ry for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( -40 °C) Canada.
If you m ust add coo lant, use a m ix tu re of wa ­
ter and coo lant addit ive . M ixing the coolant
additive with disti lled water is recommended .
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS~ &.
in Working in the engine
compartment on page
222 .
(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 especia lly impor­
tant if you live in a reg ion where t he win ­
t er is ex treme ly cold. If necessary, in­
crease the p roportion of coo lant add it ive
to 60% .
- When adding coolant addi tive to yo ur
c ooling sys tem, remembe r:
- We recommend us ing on ly coolant ad­
d itive G12++ or G13 (check the label)
for your vehicle . This coolant additive is
ava ilable at autho rized Aud i dea le rs.
Other types of antifree ze ca n sign ifi­
ca ntly reduce co rros io n protec tion. The
res ulting corrosion c an cause a loss of
coolant and serious engine damage.
- Do not add any type of r ad iator le ak seal­
ant to yo ur vehicle 's engine coolant .
Adding radiator repair flu id may adverse­
ly affect the function and performance of
your cooling system and cou ld resu lt 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.

Before you check anything in the engine com­
partment,
al ways r ead and heed all W ARN­
ING S r=;, A in Working in the engine compart­
ment on page 222.
.. Park your vehicle on a level surface.
.. Switch
off the ignition .
.. Read the eng ine coolant leve l from the cool­
ant expansion tank¢
fig. 191, ¢ page 224,
fig. 188.
With a cold engine, 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"
mark ing .
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration ¢
page 224.
To obta in an accurate read ing, the engine
must be switched
off.
The expansion 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 16 will
illum inate until yo u add coolant and the level
has been restored to normal. Even though
there is an electric coo lant level sensor, 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 authorized Audi dealer . It is not
enough merely to add coola nt.
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
The coo ling system is unde r pressure and
c an get ve ry ho t. Reduce the risk of s cald­
ing from h ot coolan t by followi ng these
steps .
- T urn
off the engine and allow it to coo l
down.
Checkin g and fillin g 229
-Protect your face, hands and arms from
escaping flu id and steam by covering the
cap with a large, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect 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 parts. Under certa in cond i­
tions, th e ethylene glycol in engine coo l­
ant can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your ve hicle's engine coolant. Add-
i ng radiator repa ir flui d may adverse ly af­
fe ct the funct ion a nd pe rfo rma nce of you r
co oling system and could re sult in damage
not covered by your New Vehicle Limi ted
War ranty.
