A WARNING
-Always observe the warning in
~ page 231, Working in the engine
compartment,
before opening the hood
and checking the engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping 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 .
(D Note
- Mounting additional lights or accessories
in front of the a ir inlets reduces the cool­
i ng effect of the rad iator . At h igh outside
temperatures or high eng ine load, the
engine co uld overheat.
- The front spo ile r has been designed to
properly distrib ute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this cou ld red uce the cooling
effect and t he engine co uld then over­
heat . Ask your aut ho rized Audi dea le r for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine R PM drops be low 1,500, you should
downshift to the next lower gear. The red a rea
at the end of the sca le ind icates maxim um
perm iss ible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position "D (Drive)" or ease
your foot off the accelerator pedal.
@ Note
The tachometer need le should only briefly
be in the red zone: yo u could damage your
engine! The beg inning of the red zone var ­
i es dependi ng on the engine.
@ For the sake of the environment
Upsh ifting early saves fuel and reduces en ­
gine noise.
Fuel gauge
The fuel gauge only works when the ignition is
o n.
If the fue l level drops below 4 gallons (15
l ite rs), the bottom LE D tu rns red and the indi­
cator light~ turns on
c::> page 21. The bot­
tom LED b link s red when the fue l level is very
l ow .
The possible range based on the current fuel
level is shown in tab@~
page 24, fig. 4.
(D Note
Never run the ta nk complet ely dry. An ir­
regular supply of f uel can cause engine
misfiring and fuel cou ld enter the exha ust
system. The cata lytic converter could t hen
overheat and be damaged .

A WARNING
- Always observe the wa rnings in
Q page 231, before opening the hood
and checking the brake fluid .
- Driv ing with low b rake fluid is a safety
haza rd. S top the car and get professional
assista nee .
- If the
1111 (USA models)/ . (Canada
mode ls) b rake system indicator light
turns on together with the ABS and ESC indicator lights, the ABS/ESC regu lating
function may have failed. F unctions that
stabilize the vehicle are no longer availa­
ble. Th is could cause the vehicle to
swerve and increase the risk of sliding .
Drive carefully to the nearest authorized
Audi dealer or other qualified workshop
and have the malfunction cor rected.
- If the brake warning/indicator light does
not go out afte r a few seconds and the
par king brake is released, or ligh ts up while you are driving, the fluid leve
l in
the brake fl uid reservo ir is too low. If you
believe that it is safe to do so, proceed
immed iate ly at low speed to the nearest
author ized Audi dealer or qualified repair
facility and have the brake system in­ spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressu re on the brake pedal to stop you r
veh icle. Do not rely on st rained bra kes to
respond with maximum stopping powe r
in critical situations . You must allow for
increased braking distances . The extra
distance used up by fading brakes could
lead to an accident.
PARK/( ®) Electromechanical parking
brake
The warning/indicator light monitors the
electromechanical parking brake .

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain ­
ed occupants.
Fi g. 1 73 Side curtain a irbags, d river 's side: s ide curta in
a ir bag location
The s ide curtain airbags are located o n both
sides of the interior above the front and rea r
side windows
c:.> fig. 173 . They are ident ified
by the word "AIRBAG" on the windshield
frame and the center roof p illar.
The s ide curtain airbag system supp lements
the safety belts and can help to reduce the risk of injury for occupants' heads and upper
torso o n the side of the vehicle tha t is struc k in a side collision
. The side curtain airbag in­
flates in side impacts and only when the vehi­ cle acceleration registered by the control un it
is h igh enough . If this rate is below the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
t h ough the car may be bad ly damaged as a re­
su lt of the co llision .
It is not possib le to de­
fine an airbag triggering range that will cover every possib le ang le of impact, s ince the cir­
cumstances will vary cons iderably between
one collision and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc .
c:,, page 175, How side cur­
tain airbags work .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a colli­
sion so that the side curtain airbags can pro­
vide protection .
The airbag system is not a substit ute for your
safety belt . Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the a irbag system can
only help to protect you if you are wear ing
you r saf ety belt and wearing it properly . This
is anothe r reason why yo u should always wear
yo ur safe ty belts, no t just because the law re ­
quires yo u to do soc:.>
page 145, General
notes .
It is important to remember that w hile the
s ide cur tain airbag system is designed to help
reduce the likelihood of ser ious injur ies, other
injuries, for example, swelling, bruising, and
minor ab rasions can also be associated with
these a irbags upon dep loyment. Remember
too, these airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offe r protection .
The s ide curtain a irbag system basic ally
cons ists of:
- The e lectronic control module and external
side impact sensors
- The side curtain airbags above the front and
rear s ide windows

A WARNING
Audi pre sense cannot overcome the laws
of physics.
It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the risk of a collision and serious personal
injuries.
- The sensors cannot always detect all ob­
jects . This increases the risk of a colli­
sion.
-Audi pre sense does not detect people or
animals or objects that are crossing the
veh icle's path ¢
page 94.
- The radar sensor's vision can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from be ing ac­
curately detected and in some cases they
may not be detected at all.
