leave your vehicle . Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the eng ine compartment after the engine is
switched off -there is a risk of damaging the
engine. For this reason, let the engine r un at
idle for approxi mately two minutes before
shutting it off.

Depending on your vehicle 's equipment , various
parking aids will help you when parking and ma­
neuvering.
The
rear park ing system is an audible parking aid
that warns you of obstacles
behind the vehicle
~ page 88.
The parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
~ page 89.
The rear view camera shows the area behind the
vehicle in the Infotainment display . This display
assists you when you are cross or parallel parking
~ page 90. In addition, you are assisted by the
functions from the park ing system plus
~ page 89.
& WARNING
-Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible for safety during parking and
for all other maneuvers.
- Please note that some surfaces , such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of children and
animals.
- The sensors can be displaced by impacts or
damage to the radiator gr ille, bumper,
wheel housing and the underbody . The park­
ing systems may become impa ired as a re­
sult . Have your authorized Audi dealer or

tem under certain circumstances:
-Objects such as barrier chains, trailer draw
bars, vertical poles or fences
- Objects above the sensors such as wall ex ­
tensions
- Objects with specific surfaces or struc ­
tures such as chain link fences or powder
snow.
- If you continue driving closer to a low-lying
object, it may disappear from the sensor
range. Note that you will no longer be
warned about this obstacle.
(D Tips
-The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as:
- certain road surfaces or for long grass.
- external ultrasonic sources e.g. from cleaning vehicles .
- heavy rain, snow or thick vehicle exhaust .
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system . When doing
this, there should be good light and weath­
er conditions.

ers , deposits or any other obstructions as it may ""'

Checking and Filling
-Keep children away from the engine com­
partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxiliary
electric fan is temperature controlled and
can switch on suddenly.
- Never open the coolant reservoir cap when
the engine is still warm. The coolant system
is pressurized and hot coolant could spray
out.
- Protect your face, hands and arm from steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns .
- If work on the fuel system or the electrical
system is necessary:
-Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment
could start a fire.
- Keep an approved fire extinguisher imme­
diately available.
- To avoid electrical shock and personal injury
while the engine is running or being started,
never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake, move
selector lever of automatic transmission
to "P" (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get-
178
ting caught in the radiator fan, V-belts or
other moving parts, or from contacting
hot parts. Tie back hair before starting,
and do not wear clothing that will hang or
droop into the engine.
- Minimize exposure to emission and chemi­
cal hazards

([) Note
When adding fluids, always make sure that
they are poured into the proper container or
filler opening, otherwise serious damage to
vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If you
see spots from oil or other vehicle fluids, have
your vehicle inspected by an authorized Audi dealer .

Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
T he cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the manufactur ­
er's glycol-basedcoolant add itive G 13 antifreeze
with anticorrosion additives (SO% for USA mod­
e ls; 60% for Canada models) . This mixt ure bot h
assures the necessary frost protec tion and pro­
tects meta l components in the engine's cooling
system from corrosion and scaling . It also raises
the boiling point of the coolant.
D o not red uce the concent ration of the coolant in
the summer by add ing p la in water.
The propor­
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- -4 0 ° F ( - 40 °C) Can ada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
_& WARNING
Before you check anythi ng i n t he engine com­
partment, a lways read and heed a ll WARN ­
INGS
¢ .&. in Working in the engine compart­
ment on page 177 .
(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in you r
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember :
- We recommend us ing only coolant add i­
tive G12+ + or G13 fo r yo ur vehicle. This
coolant addit ive is avai lab le a t aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

A WARNING ,~
- The cooling system is under pressure and
can get very hot. Reduce the risk of scald ing
from hot coolant by following these steps.
- Turn
off the engine and allow it to coo l
down.
- Protect you r face, hands and arms from
escaping fluid and steam by cover ing the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise d irection while applying
light, downward p ressure on the top of
the cap.
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in cond i­
tions, the ethylene glycol in eng ine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its orig inal container and well out
of the reach of children.
- If you dra in the coolant, it must be caught
and safely stored in a proper conta iner
clearly marked "poison".
- Do not add coolant if the expansion tank is
empty. Air cou ld enter the cooling system
and damage the eng ine. If this is the case,
do not continue driving . Seek professional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire. Excess coolant will be
fo rced o ut through the pressure relief valve
i n the cap when the e ng ine be comes hot.
- If, in an emergency, only wate r can be add­
ed, the co rrect r atio betwee n wate r and an­
tifree ze

Rad iator fan
The radiator fan switches on automatically by it­
self .
The radiator fan is driven by the engine via the V­
belt. The viscous clutch regulates th e speed of
the fan accord ing to the temperature of the cool­
ant .
An auxiliary e lectr ic radiator fan* switches on and
off depending on coo lant temperature and other
vehicle operating conditions.
After you switch the engine
off, the auxiliary fan
can continue running for up to 10 m inutes -even
with the ignition
off. It can even switch on aga in
later by itself
Q .& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up beca use the
veh icle is parked in intense sunlight.
A WARNING
- To reduce the r isk of persona l injury neve r
touch the radia to r fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not ru nning .
- The a uxiliary radiator fan sw itches on auto­
mat ically when the eng ine coolant reaches a
certa in temperature a nd will continue to run
until the coolant temperature d rops.

Check ing and F illing
CJ) Note
Never use a fast charger as a booster to start
the engine . This will serious ly damage sensi­
tive electronic components, such as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
¢ page 157. The intelli ­
gent energy management system wi ll keep the
engine battery charged better then veh icles w ith­
out this system. To make sure the addit ional
e lectrica l energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­
facture only (the same as those installed at the
time your veh icle was delivered). Specifications
are listed on the battery housing. Your author­
ized Audi dealer must code the battery in the en­
ergy management system to enable you to use
the energy manageme nt functions correctly after
replacing the battery.
If it is not possible to use a battery of this type,
the new battery must have the same capacity,
voltage (12-volts), amperage, construction and p lug sealing.
When installing the battery, make sure the igni­
tion and all electrical consumers are turned off.
@ Note
Make sure the ventilation hose on the side of
the battery is connected, otherw ise fumes or
battery acid can leak out.
@ For the sake of the environment
Because of the problem of proper disposal of
a battery, we recommend your authorized
Audi dea ler change the battery for you. Bat­
teries contain sulfuric ac id and lead and must
always be disposed of properly in compliance
190
with all environmenta l regulations. Disposing
of vehicle batteries improperly is very danger­
ous to the environment.

To reduce the risk of lime scale depos its on the
spray nozzles, use clean water with low amounts
of calcium . Always add window cleaner to the wa­
ter. When the outside temperatures are cold, an
anti-freez ing agent shou ld be added to t he water
so that it does not freeze .
(D Note
-The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective climate. A con­
centration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­
t ives to the washer fluid.
- Do not use a glass cleaner that contains
paint solvents, because th is could damage
the paint.

today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work ­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and
its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any other properly equipped and qualified workshop. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­ nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of
procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicable text and careful­ ly follow the instructions given . Always rigorously
observe the
WARNINGS provided .
Before you check anything in the engine com­
partment, always read and heed all WARNINGS
c::> .&. and c::> .&. in Working in the engine compart­
ment on page 177. Consumer information
A WARNING
-
Serious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­
mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fully familiar with these
or other procedures with respect to the ve­ hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or an­
other properly equipped and qualified work­
shop.
- The engine compartment of any motor vehi­ cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan.
It is temperature controlled and
can switch on suddenly - even when the en­
gine is off and the ignition key has been re­
moved. The radiator fan switches on auto­
matically when the coolant reaches a certain
temperature and will continue to run until
the coolant temperature drops.
- Always remove the ignition key before any­
one gets under the vehicle.
- Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle. The jack* supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
jury.
- If you must work underneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that the engine cannot be started.
- Always make sure the transmission selector
lever (automatic transmission) is in P (Park
position) and the park brake is applied.
