! 7l Engine speed limitation
A ppl ies to vehicles: with e ngin e s pee d l imitat ion
(II Engine speed maximum XXXX RPM
The engine speed is automatically limited to the
speed d isplayed in the instrument cluster. This
protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature range and you have released the accelerator ped­
al.
If the engine speed limitation was activated by
an engine control malfunction, the~ indicator
light also turns on . Make sure that the speed
does not go above the speed d isplayed . Drive to
an author ized Audi dealer or authorized Audi
Service Facility immediately to have the malfunc­
tion corrected.

CD Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Always switch the Start-Stop-System* off
when driving through water
9 page 79.
@ Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, 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 vehicle to drive
through safely.
-Avoid driving through salt water (corrosion).
Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
... Always use lead-free gasoline 9 page 208,
Fuel supply.
... Never run the tank down all the way to empty.
.,. Never put too much motor oil in your engine
9 page 220, Adding engine oil~-
.,. Never try to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
Driving and the environment
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in contact with dry grass, brush, fuel spill or
other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
CD Note
- Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic converter .
- Do not exceed the correct engine oil level
9page220.
- Do not drive until the fuel tank becomes
completely empty . The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requir­
ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur

drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station.
Cooling system
Coolant
T he 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 factory
with a permanent coolant which does not need to be changed . The coolant consists of a mixture of
specially conditioned water and the manufactur ­
er's glycol-based coolant additive G13 antifreeze
with anticorrosion additives (50% for USA mod­
els · 60% for Canadian models). This mixture
'
both assures the necessary frost protection and
protects metal components in the engine 's cool­
ing system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water.
The propor­
tion of coolant additive must be at least 50% but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to:
- -31 °F ( -3 5 °C) USA
- - 40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
_& WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN-
222
INGS ~&. in Working in the engine compart­
ment on page 216.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­ ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold . If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember:
- We recommend using only coolant addi­
tive G12++ or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce 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 engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.
