fuel cap AUDI S3 2010 Owners Manual

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.

On-Board Diagnostics monitors the components of your emission
control system . Each controlled component in your engine system
has been assigned a code. In case of a malfunction , the component
will be identified and the fault stored as a code in the control
module memory .
The Mil lamp may also illuminate if there is a leak in the on-board
fuel vapor recovery system . If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed

Malfunction Indicator Lamp (MIL) (USA
models)/ (Canada models)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 11, fig . 5 is part of the On-Board Diagnostic (OBD II) system .
The warning/indicator light illuminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabilized. This indicates that the Mil is working properly .
If the light does not go out after the engine is started, or illuminates
while you are driving, a ma lfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected . Contact your authorized Audi dealer.
If the light illuminates , the electronic speed limiter may also be
malfunctioning. For more information=>
page 21, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
=> page 220. •
Electronic speed limiter
Your vehicle may be factory equipped with tires that are rated for a
maximum speed of 130 mph (210 km/h) . This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, yo ur vehicle also has an electronic speed limiter. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information
=> page 256, "Speed rating
(letter code)".
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfun cti on Indicator Light (MIU will illuminate . If this
occurs, contact the nearest authori zed Audi dealer for assistance. _.,

labeled ask the station operator what fuel is being dispensed before
filling up your vehic le .
Service stations offering diesel fuel are generally located on truck
routes or major highways. Directories of diesel fuel stations are
usually available at diese l fuel stations.
Some states in the USA require permits to purchase diesel fuel.
Check with your State Motor Vehicle Department.
Diesel fuel may not be available outside the USA and Canada . Be
su re to check before traveling to other countries .
Winte r ope ra ti on
At temperatures be low 20° F (- 7° Cl, Diesel fuel No. 2 loses its fluidity
due to wax separation, which may c log the fuel filter or tank filter
and keep the engine from running.
To he lp the filter from being clogged by wax, the fue l filter in your
vehic le is automatically preheated. Preheating the fuel fi lter makes
operation of your vehicle poss ible with Diese l fue l No. 2 down to -
10° F (- 24° Cl.
If you expect tempe ratures below 5° F ( -15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is sufficiently winterized for the prevai ling and expected temperatures .
If not winterized or insufficiently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during
the warm -up per iod in winter. It is also normal when whitish -blue
smoke comes out of the tailpipe after starting and dur ing warm-up.
The amount of smoke depends on the outside temperature .
Do not let your diese l eng ine idle unnecessarily after a cold start.
Driving off slowly will shorten the warm -up period.

& WARNING
Improper refueling or handling of fuel can cause fire , explosion
and severe burns .
• Fuel is highly flammable and can cause severe burns and other
injuries .
• Failure to shut the engine off while refueling and /or to insert
the pump nozzle fully into the fuel filler ne ck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire .
• Never use a cellular telephone while refueling . The electromag ­
netic radiation can cause sparks that can ignite fuel vapors and
c ause a fire .
• Never get ba ck into your vehicle while refueling .
If in excep­
tional circumstances you must get back in your vehicle while refu ­
eling , make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
& WARNING (continued )
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety, we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container , full or
empty may leak and could cause a fire , especially in a crash .
• If, under e xceptional circumstances , you must transport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example , in the luggage compartment , or on
the trunk). Static electricity can build up while filling and can ignite fuel vapors cau sing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely inside the portable
container before and during filling .
- If filling a portable container made of metal , the filler nozzle
must always be in contact with the container. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment .
Fuel vapors are h ighly flammable.
- Alway s observe local and state /provincial laws regarding the
use , storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
(ANSI / ASTM F852-86I.

after refueling before starting the engine. It may take longer than
usual for the engine to start, even up to a minute. This is because
the air must first bleed out of the fuel system when starting the
engine.
W For the sak e of the environm ent
As soon as the correctly ope rated nozzle swi tches off automatical ly
for the first time, the tank is full. Do not try to add more fuel because
fue l may spill out . In addition, the expansion space in the fuel tank
wi ll be filled -causing the fuel to overflow when it becomes warm
and pollute the environment.
[ i J Tip s
• Running your engine while refuelling may cause vapors to
escape or even fuel to spill out of the tank . Th is would then shut off
the fue l nozzle before the tank is full.
• Do not refuel your veh ic le with the ignit ion switched on. The fue l
gauge may otherwise not indicate the correct fuel level after
refuel ling .•

Cold tire inflation pressure
Tire
pressure affects the overall handling, performance and safety of a vehicle.
Fig. 173 Tire pressure
label: located either on
driver's side B-pillar or
inside the fuel filler flap
Tire pressure generally refers to the amount of air in a tir e that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI). Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size. The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure." Air in
the tires expands when the tire heats up because of internal friction
when it flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold ." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations .
The tires would then be underinflated and could fail suddenly.

Maintaining proper tire pressure is one of the most important
th ings you can do to help avoid sudden tire failure . Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying .
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load -carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
On USA vehicles, the tire pressure label is located on driver's side B ­
pillar. On Canada vehicles, the tire pressure label is located either on
the driver's side B -pillar or inside the fuel filler flap. The tire pressure
