engine coolant AUDI S3 2010 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 215, "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 296,
"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.

is too low. In addition to the symbol, the following message
also appears in the display:
Switch off engine and check 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

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
vehic le. We recomme nd you use the
Automati c mode~ page 99for
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. ...

___________________________________________________ W_ a_ r_m _ a_ n_d_ c_ o_ ld _ __.11111
<£> For the s ake of th e envir onm ent
By reducing the amount of fue l you use, you a lso reduce the amount
of pollutants emitted into the air. •
Key coded settings
When the ignition is switched on, the air conditioner
settings are automatically assigned to the key being used.
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatical ly selects the settings assigned to that key .
This way every driver will maintain his/her own personal settings and does not have to reset them manually.
[ i ] Tip s
If a different driver uses your key and changes the air conditioner
sett ings, the latest adjustments wil l erase and replace the settings
you hav e stored. •

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.
