engine coolant AUDI S3 2009 Owners Manual

If the engine RPMs drop below 1 500, you should downshift to the
next lower gear. The red area at the end of the scale indicates
maximum permissible engine RPMs after the break-in period.
Before reaching this area, you should either shift into the next
higher gear or ease your foot off the accelerator pedal .
0 Note
The tachometer needle=> page 8, fig. 2 G) should not move into the
red range. If it does, then only for a very short period of time. You
could damage your engine by driving at high RPM!
<£> For the sake of the environment
Upshifting early saves fuels and reduces engine noise. •

following important points:
~
Vehicle care I I irechnical data

Instruments and warning/indicator lights
Engine cold
As long as the needle remains at the left end of the gauge, the
engine still has not reached its operating temperature . Avoid high
engine speeds, heavy engine loads and heavy throttle.
Normal temperature
When the engine has reached its operating temperature, the needle
will move into the middle of the gauge and remain there. If the engine is working hard at high outside temperatures, the needle
may turn further to the right. This is no cause for concern as long as
the
_ f_ warning light in the instrument cluster does not illuminate.
When the
-L warning light starts to flash, this can mean one of two
things: either the coolant
temperature is too high, or the coolant
level is too low=> page 30.
& WARNING
• Always observe the warning in => page 217, "Engine compart ­
ment" before opening the engine hood and checking the engine
coolant level.
• Never open the engine hood if you see or hear steam, or if you
see engine coolant dripping from the engine compartment. You
could burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant.
0 Note
• Mounting additional lights or accessories in front of the air inlets
reduces the cooling effect of the radiator . At high outside tempera ­
tures or high engine load, the engine could overheat.
• The front spoiler has been designed to properly distribute the
cooling air when the vehicle is moving. If the spoiler is damaged,
this could reduce the cooling effect and the engine could then over ­
heat. Ask your authorized Audi dealer for assistance. •
Fuel gauge
The fuel gauge works only when the ignition is on.
When the needle reaches the red area, the warning light in the
instrument cluster will illuminate=>
page 32 I). This means you
have approximately 1.8 gallons (7 liters) of fuel left in the tank.
Time
to refuel!
The total tank capacity of your vehicle is listed in=> page 300,
"Data".
0 Note
Never run the tank completely dry! An irregular supply of fuel can
cause engine misfiring and fuel could enter into the exhaust
system. The catalytic converter could then overheat and be
damaged .•
Speedometer with odometer
The speedometer shows you the vehicle speed, and the
odometer shows you how many miles (kilometers) you
have driven.

Engine cooling system malfunction _}_
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the - t symbol in the display flashes , then either the
engine coolant temperature is too high, or the coolant level
is too low . In addition to the symbol, the following message
also appears in the display :
Switch off engin e and ch ec k coolant level
- Pull off the road and stop the vehicle .

-Turn off the engine.
- Check coolant level => page
233 .
-Add coolant if necessary => page 234 .
-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
If the generator warning/indicator light should also illuminate
=> page 14, then the fan belt may be damaged .
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 58, "Emer­
gency flasher
A".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant
escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn off
the engine and allow it to cool . Follow the warning stickers
=> page 217, "Engine compartment" .

Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recomme nd the following s ettings:
- Select and set a temperature between 64
°F (+22 °C) and
84 °F (+28 °C).
- Press the !AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time . Change this set ting, as desired, to mee t your pe rsonal
needs.
The climate controls are a combination of heating, venti lation and
cooling systems, which automatica lly reduce humidity and coo l the
air inside your vehic le .
The air temperature, air flow and air distribution are automatically
regu lated to achieve and maintain the desired passenger compart ­
ment temperature as quick ly as possible.
The system automatically compensates for changes in the outside
temperature and for the intensity of the sun light entering the
veh ic le. We recommend you use the
Automat ic mode=> page 101
for year -round comfort.
P lease note the following :
Turn on the air conditioner to reduce humidity in the vehic le. This
a lso prevent the window s from fogging up. When the outside temperature is high and the air is very humid,
c
ondensat ion from the evaporator may drip under the vehicle . T his
is normal and does not indicate a leak.
I f the outside temperature is low, the fan normally only switches to
a higher speed once the engine coola nt has war med u p sufficiently .
T he air conditioner temporarily sw itches off when you drive off from
a standstill using fu ll throttle to save engine power.
The comp ressor also swi tches off if the coolant temperatu re is to o
high so that the engine can be adequate ly cooled under extreme
lo ads .
Air pollutants filt er
The air po llutants fi lter (a combined partic le filter and activated
charcoal fi lter) reduces or eliminates outside air pollution (dust, or
p ollen) from en ter ing the vehic le .
The air po llutants fi lter must be changed at the intervals specified
in your Warranty
& Maintenance bo oklet, so that the ai r conditioner
can proper ly work.
I f you drive your vehicle in an area with high air pol lution, the filter
may need to be changed m ore freque ntly tha n specified in your
Audi Warranty
& Maintenance booklet. If in doubt, ask your autho­
r iz ed Aud i Service Adviso r fo r a dvice .
& WARNING
Redu ced vi sibility i s dangerou s and can cause accidents .
• For saf e driving it is very important that all window s be free of
ice , sno w and conden sation.
• Fully familiarize yourself with the proper use and fun ction of
the heating and ventil ation sy stem and especially how to defog
and defrost the windows. ...

Starting and stopping the engine
Starting the engine
The engine can only be started with on original Audi key
and the clutch pedal* depressed.
- Set the parking brake.
Move the selector lever to the neutral position (automatic
transmission): selector lever in P or N) =>
&.
- On vehicles with manual transmission, fully depress the
clutch pedal.
- Turn the ignition key to position@=>
page 108, fig. 113
- do not depress the gas pedal when starting the engine!
- Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure . This normal
and no need for concern.
If the engine does not star t immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled .
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.
Controls and equip ­
ment
0 Note
• Avoid high engine speeds, fast acceleration or heavy engine
loads while the engine is still cold. This could damage the engine!
• The engine cannot be started by pushing o r towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emis­
sions, 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 108 , fig. 113.
& WARNING
• Never turn off the engine until the vehicle 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. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition 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. .,

Weig ht dis tributi on
Towing a loaded trailer with an empty car resu lts in a high ly
unstable distribution of weight . If this cannot be avoided drive at
very low speeds on ly to avoid the risk of losing steering control.
A "ba lanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and permis ­
sib le while keeping the trai ler as light as possib le under the circum ­
stances. Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle while observing tongue load requirements and vehicle loading considerations .
Speed
The higher the speed, the more difficult it becomes for the driver to
control the rig . Do not drive at the maximum permissible speed.
Reduce your speed even more under unfavorable load, weather or
wind conditions -particularly when going downhill.
Reduce vehicle speed
imm ed ia tely if the trailer shows the sl ightest
sign of swaying. Do not try to s top the s wayi ng by a ccelerating .
Observe speed limits . In some areas speeds for vehicles towing
trai lers are lower than for regular vehicles.
Always app ly brakes early. When driving downhill, shift into lower
gear to use the engine braking effect to slow down the vehicle. Use
of the brakes alone can cause them to overheat and fail.
C oo la nt tempe ra tu re
The coolant temperature gauge ~ page 9 must be observed care ­
ful ly. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or switch off the air condit ioner.
If the coolant temperature warning light in the instrument cluster
starts flashing -~-, pull off the road, stop and let the engine
idle for
about two minutes to prevent heat build -up .
& WARNING
An yone not p rope rly res train ed in a mo ving vehi cle is a t a mu ch
gre ater risk in a n accident. Neve r let an yone ride in your car who
is not p rop erly we ari ng th e res tra int s pro vide d b y Aud i.

Trailer towing tips
Important to know
Your vehicle handles different ly when towing a trailer because of
the additional weight and weight distribution . Safety, performance
and economy w ill great ly depend on how carefu lly you load your
trailer and operate your rig.
Before you actually tow you r trailer, practice turn ing, stopping and
backing up in an area away from traffic. Keep practicing unti l you
have complete ly become familiar with the way your vehicle -trailer
combination behaves and responds .
Backing up is difficult and requires practice. Backing up with a
trailer genera lly requires steering ac tion opposite of that when
backing up your vehicle without a trailer .
Maintain a greater distance between your vehicle and the one in
front of you. You will need more room to stop.
T o compensate for the trailer, you wi ll need a larger than normal
turning radius .
When passing, remember that you cannot accelerate as fast as you n ormal ly wou ld because of the added load . Make su re you have
enough room to pass. After passing, al low plenty of room for your
trailer before changing lanes again .
Avoid jerky starts, sharp turns o r rapid lane changes.
