Intelligent Technology

— Utilize the engine braking effect when driv-
ing downhill by selecting the “S” driving
program > page 82. This reduces the load
on the brakes. If you need to brake addition-
ally, brake in intervals and not continuously.
G) Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.
— Also refer to the information about brake
fluid > page 209.
Messages
EG / ©) Brakes: malfunction! Safely stop ve-
hicle
There is a malfunction in the brake system. If
[ES / Gana Blalso turn on, there is a malfunc-
tion in the ABS, ESC, and braking distribution. If
the brake booster is not working, you have to use
much more force when braking the vehicle.
Do not continue driving. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance. Read and follow the other safety pre-
cautions > A\.
GG / @ Warning! No brake booster function
If the brake booster is not working, you have to
use much more force when braking the vehicle.
See an authorized Audi dealer or authorized Audi
Service Facility for assistance.
GG if @ Brake pads: wear limit reached. You
can continue driving. Please contact Service
The brake pads are worn. Drive to an authorized
Audi dealer or authorized Audi Service Facility as
soon as possible to have the malfunction correct-
ed.
Ga / @ Parking brake: malfunction! Safely
stop vehicle. See owner's manual
— If the indicator light and the message appear
when the vehicle is stationary or after switch-
ing the ignition on, check if you can release the
parking brake. If you cannot release the parking
brake, see an authorized Audi dealer or author-
ized Audi Service Facility. If you can release the
parking brake and the message still appears,
see an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
— If the indicator light and message appear while
driving, the hill start assist or emergency brak-
ing function may be malfunctioning. It may not
be possible to set the parking brake or release
it once it has been set. Do not park your vehicle
on hills. See an authorized Audi dealer or au-
thorized Audi Service Facility for assistance.
Other indicator lights
When you switch the ignition on, the IBRAKE| /@
indicator light turns on briefly to check the func-
tion. If the indicator light does not turn on, there
is a system malfunction.
fe / @ stays on, there is a malfunction in
the brake system.

ZA\ WARNING
If a malfunction occurs in the ABS, ESC, and
braking distribution, interventions that stabi-
lize the vehicle will no longer be available.
This could cause the vehicle to swerve, which
increases the risk that the vehicle will slide.
Do not continue driving. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.

Steering
Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
speed. The settings depend on the selected Audi
drive select* mode.

Checking and Filling


High voltage! Switch off the engine be-
fore coming into contact with any igni-
tion system components!

The catalytic converter can be damaged
"271i if the oil level is too high!

Always follow the instructions in the op-
aa erating manual.


ZA\ WARNING
— Turn the engine off.
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Allow the engine to cool.
— Keep children away from the motor com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contained
in the coolant) can catch fire.
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— Never open the hood when there is steam or
coolant escaping from the motor compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
—The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure. There
is a risk of burns
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“P” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.


Z\ WARNING
California Proposition 65 Warning:
— Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali-
fornia to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
— Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California

Checking the brake fluid level
> Read the brake fluid level on the brake fluid
reservoir > page 203, fig. 168. The brake fluid
level must be between the MIN and MAX mark-
ings > A\.
The brake fluid level is monitored automatically.
Message
EG / @® Brakes: stop vehicle and check brake
fluid level
Stop the vehicle and check the brake fluid level.
See an authorized Audi dealer or authorized Audi
Service Facility for assistance.
Changing the brake fluid
Brake fluid should be changed at regular inter-
vals. Have the brake fluid changed by an author-
ized Audi dealer or authorized Audi Service Facili-
ty. The authorized Audi dealer or authorized Audi
Service Facility will inform you of the replace-
ment intervals.
ZX WARNING
— If the brake fluid level is below the MIN
marking, it can impair the braking effect and
driving safety, which increase the risk of an
accident. Do not continue driving. See an au-
thorized Audi dealer or authorized Audi
Service Facility for assistance.
— If the brake fluid is old, bubbles may form in
the brake system during heavy braking. This
could impair braking performance and driv-
ing safety, which increases the risk of an ac-
cident.
— The brake fluid in your vehicle must meet
the standard VW 501 14 and is available at
an authorized Audi dealer or authorized
Audi Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-

ard (FMVSS) 116 DOT 4, Class 6.
@) Note
— If the brake fluid level is above the MAX
marking, brake fluid may leak out over the
edge of the reservoir and result in damage
to the vehicle.

— Do not allow any brake fluid to come into
contact with the vehicle paint, because it
will corrode the paint.
Electrical system
If the fz or = indicator light turns on, there is a
malfunction in the generator, the battery, or the
vehicle electrical system.
= Electrical system: malfunction! Battery is
not being charged
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately. Turn off all un-
necessary electrical equipment because it will
drain the battery. See an authorized Audi dealer
or authorized Audi Service Facility if the battery
charge level is too low.
= Electrical system: low battery charge. Bat-
tery
will be charged while driving
The starting ability may be impaired.
