158 Driving and en vi ro nm ent
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 loaded
vehicles .
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 highe r tha n the
bottom of the vehicle body.
- Do not d rive faster than wa lking speed.
_& WARNING
After d riving 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.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv
ing through it.
- Do not stop the veh icle, drive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.

Catalytic converter
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 17 4,
Fuel supply .
.. Never run the tank down all the way to emp
ty.
.. Never put too much motor o il in your eng ine
r::;> page 183, Adding engine oil~-
.. Never try to p ush- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean
up" dev ice built into the exhaust system of
t h e vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert
er and prope r funct ion ing of the engine.
A WARNING
- 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 wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converter .
- Do not exceed the correct engine oil level
¢page 183.
-Do not drive until the fuel tank becomes
completely empty . The engine could mis-
fire. Unburned fuel could also get into ..,.
-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wa it until no steam or
coolant can be seen or heard before care
fully opening the hood.
- Keep children away from the engine com
partment .
- Never spill fluids on hot engine compo
nents. They can cause a fire.
- Never touch the radiator fan. The auxili
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool
ant system is pressurized and hot cool
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- If work on the fuel system or the electri
cal system is necessary:
- 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).
Checking and filling 179
-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 wear no clothing that will
hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards

Engine cooling system
Coolant
T he engine coolan t 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 .
T he cooling system has been filled at the fac
tory with a permanent coolant which does not
need to be changed . The coolan t consis ts of a
mixture of water and the manufacturer 's gly
col-basedcoolant additive G12 ++ antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canad ian models). This mix
ture both assures the necessary frost protec
tion and protects metal components in the
engine 's cooling system from corrosion and
scaling. It also raises th e boiling point of the
c oolant.
Do not reduce the concentration of the coo l
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 antifree ze protection and cooling efficien
cy . If the coolant frost protection is too low,
the coolant could freeze and damage the veh i
cle heating and eng ine cooling system .
For year-round driving, an tifree ze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 5 °C) USA
- -40 °F ( -40 °C) Canada.
You can mix the G12 ++ coolant addit ive with
other additives (G12+ or G12) . Always check
with your authorized Audi dealer.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
-
Checkin g and fillin g 185
WARNINGS c:::> .& in Working in the engine
compartment on page 178.
(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 extreme ly cold . If necessary, in
crease the proportion of coo lant add itive
to 60% .
- Whe n adding coolant additive to your
cooling system, remember :
- We recommend using only coo lant ad
ditive G12++ (check the labe l) for your
vehicle . This coolant additive is avai la
ble at authorized Audi dealers. Other
types of ant ifreeze can significantly re
duce corrosion protection . The result
ing corrosion can cause a loss of cool
ant and ser ious eng ine damage.
- Do not add any type of rad iator leak seal
ant to yo ur vehicle's engine coolant .
Add ing radiator repair fluid may adverse
ly affect the function and performance of
your cooling system and could 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.

186 Checking and filling
Before you check anything in the engine com
partment,
alwa ys r ea d and heed all WARN
INGS ¢ A in Working in the engine
comportment on page 178.
• Switch the ignition off .
• Read the coo lant level at the coolant expan
s ion tank ¢
fig. 141 . With a co ld engine, it
must be above the "min" mark. W ith a hot
engine, it can be a little above the indicated
range.
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration .
To obtain an accurate reading , the engine
must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor .
When the coolant level is too low, the warning light in the Auto- Check System ¢
page 31 will
blink until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sen sor, we still rec
ommend you check the coolant leve l from
time to time.
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 A udi 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.
@ Note
Do not add any type of ra diator leak seal
ant to yo ur vehicle's eng ine coolant. Add
ing radiator repair f luid 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 anyth ing in the engine com
partment,
always read and heed all WARN
INGS ¢ A in Working in the engine comport
ment on page 178 .
•Turnoff the engine.
• Let the eng ine cool down.
• Place a thick rag ove r the coolant expansion
tank
¢ page 185, fig . 141 and carefully
tw ist the cap counter-clockwise ¢&_ .
• Add coolant.
• Twis t the cap o n aga in
tightly.
Replacement engine coolant must conform to
exact spec ificat ions
¢ page 185, Coolant.
E ven in a n emerge ncy, if coo lant addi -
t ive G1 2++, G12+ or G12 is not ava ilable , do
not use a d ifferen t addit ive. Use plain water
instead unti l you can get the cor rect additive
and can restore the correct ratio . This sho uld
be done as soon as possible .
If you have los t a considerab le amo unt o f
coolant , then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the engine is cold.
Always use
new engine coo la nt whe n refilling .
Do not fill coola nt above the "MAX" mark. Ex
