the starting process is automatically stopped
after a sho rt time. Repeat starting procedu re.
Sw it c hing the ignition /engine off
automatically *
The following applies to vehicles with Start­
Stop-System* /Hybrid drive*: to prevent the
battery from drain ing, the ignit ion and the en­
g ine will switch off automatically under the
following conditions :
- T he veh icle has al ready bee n driven .
- The driver's door is opened .
- The driver's seat belt is removed.
- The brake peda l is not pressed down.
- The veh icle is stationary.
I n th is case, the activated low beam w ill be re­
p laced by the side marker lights. The side
marker lights will switch off after a certain pe­
riod of time or w hen you lock the vehicle .
A WARNING
-Never allow the engine to run in confined
spaces - danger of asphyxiation .
- Never remove the ign ition key from the
ignition lock while the vehicle is moving.
Otherw ise, the steering lock could sud- denly engage and yo
u wo uld not be able
to steer the vehicle .
- Always take the key with you whenever
you leave your vehicle. Otherw ise, the
engine could be started or electrical
equ ipment such as the power windows
could be operated. This can lead to seri­
ous injury.
- Never leave children or persons requiring
assistance unattended in the vehicle . The
doors can be locked using the remote
transmitte r, prevent ing people from es­
caping from the ve hicle on t heir own in
t he event of an emergency. Depending
on the time of year, peop le inside the ve ­
hicle can be exposed to very high or very
low tempe ratu res .
(D Note
Avoid high eng ine rpm, f ull throttle and
heavy engine loads unti l the engine has
r eached operating temperat ure - ot her­
wise yo u risk eng ine damage.
@ For the sake of the environment
Do not let the engine run wh ile pa rked to
warm up. Begin driving immediately. This
r educes unnecessary emissions .
(D Tips
-If the key cannot be removed from the
ignition lock, you have to pull the me­
chanical key out of the master key in or­
der to be able to lock the vehicle
¢page 38.
-After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must f irst bu ild up
in the hydraulic valve adjusters . This is
normal and not a cause for concern.
- If you leave the ve hicle with the ignition
switched on, the ignit io n w ill switch off
afte r a certain per iod of t im e. Please
note that ele ctri cal eq uipment su ch as
exterior l igh ts will sw itch off as well
when that happens .

on the time of year, people inside the ve­
hicle can be exposed to very high or very
low temperatures .
0 Note
Avoid high engine rpm, full throttle and
heavy engine loads until the engine has
reached operating temperature -other-
wise you risk engine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up . Begin driving immediately. This
reduces unnecessary emissions.
@ Tips
- After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must first build up in the hydraulic valve adjusters . This is
normal and not a cause for concern .
- If you leave the vehicle with the ignition
switched on, the ignition will switch off
after a certain period of time . Please
note that electrical equipment such as
exterior lights will switch off as well
when that happens .
Switching engine off
App lies to vehicles: with Conve nie nce key
"" Bring your vehicle to a complete stop.
... Move the selector lever to the P or N posi­
tion.
"" Press the
!START ENGINE STOPI button
r:::;, page 86, fig. 100 .
Steering lock
The steering locks when you turn the engine
off using the

ton. The vehicle speed must be less than 6
mph/ 10 km/h.
A WARNING
- Never turn off the engine before the ve­
hicle has come to a complete stop . The
full function of the brake booster and the power steering is not guaranteed . You
must use more force to turn or brake if
necessary . Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injuries.
- For safety reasons, you should always
park your vehicle with the selector lever
in P . Otherwise, the vehicle could inad­
vertently roll away.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the engine and removed the ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment.
- Always take the key with you whenever you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated. This can lead to seri­
ous inJury.
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preventing people from es­
caping from the vehicle on their own in
the event of an emergency. Depending
on the time of year, people inside the ve­ hicle can be exposed to very high or very
low temperatures.
(D Note
If the engine has been under heavy load
for an extended period, heat builds up in
the engine compartment after the engine is switched off -there is a risk of damaging
the engine. Allow the engine to run at idle
for about two minutes before switching it
off .

Fa u lts in th e brake sy stem
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circuits may have failed~.&. .
Low brak e flu id level
Malfunct ions can occur in the brake system if
the brake fl uid leve l is too low . T he b rake fluid
l eve l is monito red electronically .
Brake booster
The brake booster increases the pressure that
you generate w ith the brake pedal.
It only op­
e rates while the eng ine is running or with the
i gnit ion sw itched on (hybr id dr ive*) ~.&, .
Brake lining wear statu s
Brake lining wear may be checked by visual in ­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sa ry, the wheel may be removed for this in­
spection
~ page 2 74, Changing a wheel.
.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often . This could cause the
brakes to get hot and dimin ish b raking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the b rakes to
overheat, premat ure wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter , driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
Int ellig ent technolog y 201
for a test. Brakes will dry and ice coat­
ings w ill be cleaned off after a few care­
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
f low to the front brakes is not obst ruct­
ed. Otherw ise the brake system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopping distance . Avoid driving
the vehicle and have it towed to the near­
est a uthori zed Audi dea ler or qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

218 Clea ning and protec tio n
- Never use sp onges designed to remove
insects, or a ny kitchen scouring sponges
or similar products . They can dama ge
you r paint f inish.
- Never use a dry cloth or s ponge to clean
the headligh ts. On ly use wet clot hs or
sponges to prevent scratches.
It i s best
to use soapy water.
- You should rem ove debris (suc h as in ­
sects) from the headlight lenses on a
regular basis, fo r example when refuel­
i ng your vehicle. Never clean the head­
li ghts w ith a dry cloth or sponge. Use a
wet cloth or sponge.
It is best to use
soapy water.
@ For the sake of the environment
On ly wash the vehicle in facilit ies specially
designed for that pu rpose. This w ill reduce
t he risk of d irty water contami nated with
oil from en tering the sewer system. In
some areas, washing vehicles outside of
these facilities is prohibited .
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you
observe a few simple rules.
.. Before us ing the power washe r, make sure
you have read and understood the WARN­
INGS¢
A in General information on
page 216 .
• Always follow the operating instructions for
the power washer .
• Make sure that the jet o n the spray hose
produces a "fan shaped sp ray ".
• Do
not ho ld the spray nozzle too close t o
soft materia ls.
Keep a d istance from soft mate rials such as
rubber hoses or insulat ing mater ial as well as
sensors and camera lenses .
When clea ning the veh icle w it h a power wash­
e r
always fo llow the operating instructions.
This applies particul arly to the operating pres­
sure and the spraying distance. Do not po int the spray di
rectly at the seals around the side
windows, around the doors, on the rear lid or
on the Panoram ic sliding sunroof* . Likewise,
do not po int it direct ly at tires, rubber hoses,
insulat ion material or sensors
¢ page 219.
Hold the spray nozz le at least 1.3 ft (0.4 m)
away from the vehicle.
Do not use a high-pressure power washer to
remove snow and ice .
Do not use a jet which sprays water in a direct
stream or one that has a rotating jet .
Water tempera ture sho uld no t exceed 140 ° F
(60 °().
_& WARNING
Neve r wash tires with a jet t hat sprays wa­
ter in a direct stream . Th is could cause in­
v is ible damage to the t ires and weaken
them, even if the spray is from a relative ly
l ong distance and for a short time. Dam­
aged and weakened tires can fail and cause
accidents and personal in ju ry .
(D Note
To avoid damaging you r vehicle, always
make sure that there is suffic ient d istance
between the spray head and soft materia ls
l ike rubber hoses, plast ic pa rts and sound­
deade ning mater ia ls as well as sensors
and camera lenses. Never a im the sp ray
head at the same point fo r a long time .
This also applies to cleaning headlights
and painted bumpers. Remembe r: the
closer the nozzle is to the surface of the
mater ia l, the greater the stress on the ma­
terial.

220 Cleaning and protec tio n
- do not clean the camera lenses and the
area around them with the pressure
washer.
- Never use warm or hot water to remove
snow or ice from the camera lens. T his
could cause the lens to crack.
- Never clean the camera lens with abra­
sive prod ucts .
Waxing and Polishing
Wa xing
A good wax coating protects the vehicle paint
to a large extent against the environmental
factors listed under
qpage 216, Washing and
even against slight scratches .
You can use a liquid car wax to protect your pa int as soon as one week after your veh icle
has been delivered.
Even if you regularly use a
w axi ng process in
automatic car washes, we recommend that
you manua lly app ly a coat of wax to give the
pa int extra protection, particularly if water no
longer beads on the clean paint .
Protect p lastic body parts with car wax in the
same way as the vehicle body.
During wa rm weather dead insects tend to
collect on the front bumper and on the for­
ward area of the hood . They are much easier
to remove from paint that is waxed
often.
P oli shing
Polish your vehicle on ly if the paint has lost its
shine and the g loss cannot be brought back
with wax .
I f the polish used does not contain preserva ­
tive compounds, the paint must be waxed af­
terwards .

above the "MAX" marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢
page 235.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 30 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized Audi dealer.
It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your

Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 233.
... Turn off the engine .
... Let the engine cool down.
Checking and filling 241
... Place a thick rag over the coolant expansion
tank ¢
page 240, fig. 199 and carefully turn
the cap counter-clockwise ¢
A.
... Add coolant.
... Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 240, Coolant. We
recommend using only coolant additive
Gl2+
+, Gl3
or in an emergency Gl2 +. Do not use a
different additive . In an emergency use plain
water until you can get the correct additive and can restore the correct ratio. This should
be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en­
gine becomes hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap .
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
-Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
