jury, scalding, accidents, and burns. For this
reason, follow all the warnings and general
safety precautions provided in the following in-
formation. The vehicle's motor compartment is
a dangerous area. > /A\.
Explanation of warnings (sticker in the motor
compartment):

Hot motor components!
@® Rotating parts!


The radiator fan can switch on at any
LB, time!
— The coolant expansion tank cap is equipped
with a seal that must never be removed un-
der any circumstances > page 243. If the
coolant expansion tank is not sealed, con-
tact an authorized Audi dealer or authorized
Audi Service Facility.
— The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure.
—To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— 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 chemicals to as short
a time as possible.


High voltage! The voltage in the high-
voltage system is high enough to cause
fatal injuries. Touching a damaged high-
voltage component can result in a fatal
electric shock.


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

ZA\ WARNING
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Keep children away from the motor com-
partment.
— Never spill operating fluids in the motor
compartment.
— Avoid short circuits in the electrical system.
— 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

— The cap on the coolant expansion tank may
only be opened by an authorized Audi dealer
ZA WARNING
The voltage in the high-voltage system is high
enough to cause fatal injuries. Touching a
damaged high-voltage component can result
in a fatal electric shock. The components in
the high-voltage system are marked with a
warning label which warns of the high-volt-
age.
— The voltage level in the high-voltage system
is still dangerous and potentially life-threat-
ening when the ignition is switched off.
— Never perform work on orange high-voltage
cables or on high-voltage components. Only
authorized repair facilities that are certified
may perform work on the high-voltage sys-
tem.

Coolant level


Fig. 158 Motor compartment: coolant expansion tank
Observe the safety precautions > page 240, Gen-
eral information.
Checking the coolant level
> Park the vehicle on a level surface.
> Switch the ignition off.
> Open the hood > page 241.
The coolant expansion tank is located in the ple-
num chamber under a cover. Slide the cover that
is located below the windshield wipers on the
front passenger's side toward the windshield and
remove the cover > page 242, fig. 157.
> Read the coolant level on the floating gauge for
the expansion tank without opening the cap.
The coolant level must be between the Min and
Max markings when the coolant is cold
> fig. 158
> 1 turns on, do not continue driving
=> page 242.
> If the coolant level is just over the Min marking,
drive to an authorized Audi dealer or authorized
Audi Service Facility immediately.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected.

Z\ WARNING
— The engine/motor compartment in any vehi-
cle can be a dangerous area. Switch the igni-
tion off and allow the cooling system to cool
down. Always follow the information found
in > page 240, General information.

— Never open the hood if you can see or hear
steam or coolant escaping from the motor
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the motor
compartment with caution.
— The coolant expansion tank may only be
opened and filled by an authorized Audi
dealer or authorized Audi Service Facility.
— The coolant expansion tank cap is equipped
with a seal that must never be removed un-
der any circumstances > page 243. If the
coolant expansion tank is not sealed, con-
tact an authorized Audi dealer or authorized
Audi Service Facility.
— When adding coolant, it may leak into the
inside of high-voltage components and
cause a short circuit, increasing the risk of
fire.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.

Accessories and technical changes

Technical Modifications
Interference with electronic components, their
software, the wiring, and data transfer may cause
malfunctions. Because of the way electronic com-
ponents are interconnected, such malfunctions
can also impair systems that are not directly in-
volved. This means that you risk both a substan-
tial reduction in the operational safety of your ve-
hicle and increased wear of vehicle components.
Some convenience functions, such as the conven-
ience turn signal function, individual door open-
ing function, and displays, can be reprogrammed
using special workshop equipment. If functions
are reprogrammed, the information and descrip-
tions about these functions in this Owner's Man-
ual may no longer apply to the changed func-
tions. Audi recommends that an authorized Audi
dealer or authorized Audi Service Facility perform
and verify any reprogramming procedures.

ZA\ WARNING
Maintenance procedures, repairs, or technical
modifications that are performed incorrectly
increase the risk of an accident and can lead
to serious injuries.

ZA WARNING
The engine/motor compartment in any motor
vehicle is a potentially dangerous area and can
cause serious personal injury.
— Always use extreme caution when doing any
work in the motor compartment. Always fol-
low commonly accepted safety practices and
use common sense. Never risk personal in-
jury.
— Never perform any work in the motor com-
partment unless you know exactly how to
carry out the job and have the correct tech-
nical information and the correct tools.
— If you are uncertain about what to do, have
the work performed by an authorized Audi
dealer, an authorized Audi Service Facility,
or another qualified workshop. Serious per-
sonal injury may result from improperly per-
formed work.

CG) Note
— Maintenance procedures, repairs or techni-
cal modifications that are performed incor-
rectly can cause damage to the vehicle, such
as corrosion.
— If emergency repairs must be performed,
take your vehicle to an authorized Audi deal-
er or authorized Audi Service Facility as soon
as possible.
— Audi is not liable for damage to the vehicle
resulting from failure to comply with these
guidelines.
(@) For the sake of the environment
— Regular maintenance can help protect the
environment.
— Technical modifications to the vehicle may
have a negative affect on energy use.
@) For the sake of the environment
Certain components in your vehicle such as
undeployed airbag modules, pretensioners
and remote control batteries may contain Per-
chlorate Material - special handling may ap-
ply, See www.dtsc.ca.gov/hazardouswaste/
perchlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are scrap-
ped, all applicable laws and regulations must
be observed. Your authorized Audi dealer is
familiar with these requirements and we rec-
ommend that you have your dealer perform
this service for you.
(i) Tips
Because of your vehicle's aluminum body de-
sign, all service and repair procedures affect-
ing the body should be performed by an au-
thorized Audi dealer or authorized Audi Serv-
ice Facility, who will perform the work accord-
ing to Audi factory specifications. Only Audi
Genuine Parts are used when Audi experts
perform repair or service procedures. Failure
to use Audi Genuine Parts or Audi Genuine Ac-
cessories or performing repairs incorrectly
may result in severe vehicle damage, such as
corrosion.
