one half. Never drive faster than the posted speed limit and weather
conditions permit. •
Reducing unnecessary =citing
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the engine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings , or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fuel than is burned starting the engine again .
It takes a long time for the engine to warm up fu lly when it is
running at idle. However, wear and noxious emissions are especially
high when the engine is warming up. So you should drive away as
soon as you start the engine and avoid running at high rpms while
the engine is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended idling also produces heat, which could result in overheating or other damage to the vehicle or other
property .•
Regu1ar ma1--.tenance
A badly tuned engine unnecessarily wastes a lot of fuel.
-Have your vehic le serviced at regular intervals .
By having your vehicle regularly serviced by an Audi dealer helps to
ensure that it runs properly and economically. The condition of your
vehic le not only affects its safety and abi lity to hold its value, it also
affects
fuel con sumpt ion.
C hec k your o il e ach time you fill your t ank.
The amount of oil used is related to engine load and speed.
It is norma l for the oil consumption of a new engine to reach its
lowest va lue after a certain mileage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption .
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. Lack of proper ma intenance as well as improper use of the
vehic le wi ll impair the function of the emission control system and
cou ld lead to damage.
• Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not alter or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
vehicle's Em ission Control System and other important vehicle
components .•
Fewer short tr ips
Fuel consumption will always be relatively high on short
trips.
- Try to avoid driving short dista nces wi th a cold engine. _,

from fading. Slight color variations will develop in normal use and
are not an indication of material deterioration.
0 Note
• Never use chemical solvents (e.g. lighter fluid, turpentine),
waxes, shoe polish or similar products on Alcantara ® surfaces.
• To avoid damage, have stubborn stains removed by a commer­
cial cleaning specialist.
• Do not use brushes, stiff sponges or similarly abrasive cleaning
aids .•
Safety belts
Only well-maintained safety belts work reliably when
needed.
- Keep belts clean.
- For cleaning, use a mild soap and water solution . Let
belts dry thoroughly and away from direct sunlight .
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash.
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them.
& WARNING (continued)
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your Audi dealer.
• Always read and heed all WARNINGS and other information
~ page282. a
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine ~ &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts.
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti -corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
2 l, or if you have the engine washed, the anti­
corrosion treatment is almost always removed as well. It is therefore .,_
21 Use only th e correct cleaning solut ions. N ev er use gasolin e or di ese l fu el.

models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects metal components in the
engine's cooling 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.

coolant could free ze and damage the veh icle heating and engine
cooling system .
For year-round driving , antifreeze is added at the factory for temper ­
atures down to:
• -31 °F ( -35 °c1 usA
• - 40 °F ( - 40 °C) Canada.
You can mix the
Gl 2+ + coolant additive with other additives (G12+
or G12). Always check w ith your authorized Audi dealer.

• Before winter sets in, have the coolant checked to see if the
coo lant additive in your vehicle is sufficient to meet the climate
conditions. This is especia lly important if you live in a region where
the winter is extremely cold . If necessary, increase the proportion of
coolant additive to 60%.
• When adding coolan t additive to your coo ling system,
remember:
-We recommend using only coolant additive
G12+ + (check the
label) for your vehicle. This coolant additive is avai lable at autho­
riz ed Audi dealers. Other types of antifreeze can significantly reduce 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 coolan t. Adding radiator repair fluid may adversely 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.

Before you check anything in the engine compartment,
alw ays read and h eed all WARNINGS ~ & in "Working in
the eng ine compartment" on page 301.
- Turn off the ignition.
- Read the e ngine coo lant level from the coo lant expan -
sion tank~ fig. 242. With a cold engi ne, the coolant level
sho uld be between the "min" and "max" markings. W hen
the engine is warm, the level may be slightly above the
"max" marking .
The location of the coolant expansion tank can be seen in the
engine compartment illustration~
page 302.

•
T o obtain an accurate reading, the engine must be switched off .
The expansion tank in your vehic le 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 37 will blink until you add coo lant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coo lant level
from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer . It is not enough merely to add
coo la nt.
In a sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating .
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant . Adding radiator repair fluid may adversely affect the func­
tion 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 compartment,
always read and heed all WARNINGS~ & in "Working in
the engine compartment" on
page 301.
- Turn off the engine.
- Let the engine cool down. Place
a thick rag over the coolant expansion tank
~ page 308, fig. 242 and carefully twist the cap counter­
clockwise ~& .
Add coolant.
- Twist the cap on again
tightly .
Replacement engine coolant must conform to exact specifications
~ page 307, "Coolant". Even in an emergency, if coolant additive
G12++ , G12 + or G12 is not availab le, do not use a different additive .
Use plain water instead until you can get the correct add itive and
can restore the correct ratio. This shou ld be done as soon as
possible.
If you have lost a considerab le amount of coolant, then you should
add cold antifreeze and cold water only when the engine is cold .
A lw ays use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Excess coolant will be
forced out through the pressure relief valve in the cap when the
eng ine becomes hot.
& 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 antifreeze or coolant on
the exhaust system or hot engine parts. Under certain condi-
tions , the ethylene glycol in engine coolant can catch fire . ...
