132 Audi side assist
-The radar sensor's vision can be reduced
or entirely blocked by rain, snow, and
heavy spray . This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the direction you
are traveling and the relevant area
around the vehicle.
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- Side assist signal does not work around
tight corners (turning radius less than
328 feet, or 100 m).
- Side assist is no replacement for the driv­
er's full attention. The driver alone is re­
sponsible for lane changes and similar
driving maneuvers. Always keep an eye
on the direction you are traveling and the relevant area around the vehicle.
- To ensure that you do not adversely af­
fect side assist, do not block the area on
the rear bumper where the radar sensors
are located with foreign objects (such as
stickers or bicycle racks).
- Make sure that the signal light on the
outside mirror is not blocked by stickers
or other items.
(Di Tips
- Side assist automatically deactivates if it
detects that the radar sensors are
blocked ¢
page 13 7. The indicator light
on the button goes out .
- The area on the bumper where the radar
sensors are located must consistently re­
main free of snow, ice, and heavy soiling
so that side assist can function properly.
Follow the additional notes on
¢page 138.
-For vehicles with a factory installed tow­
ing hitch* or a trailer hitch* that was in­
stalled later according to factory specifi­
cations, side assist is automatically deac- tivated
as soon as the electrical connec­
tion to the trailer electrical socket is made
¢ page 137.
-For vehicles with a trailer hitch that was
not installed according to factory specifi­
cations, switch off the side assist when
towing a trailer .
- Additional tinting on the front side win­
dows can make it harder to see and cor­
rectly understand the signal light on the
outside mirror.

Fig. 153 Sc hematic illustration: Sensor detectio n area
The detection ¢ fig. 153 of the radar sensor
detection area is made up of:
-
- the approach area (light red area) (D, about
230 feet (70 m) behind the vehicle, and
- the "blind spot" (dark red area) @.
The radar sensors cover the adjacent left and
right lanes. Other lanes are
not covered by the
radar sensors.
(D Tips
Side assist does not measure actual lane
width. The system assumes a fixed lane
width . Detection in the left and right lanes
is based on this assumed lane width.
When driving on narrow roads or when
driving to the left or right of the center of
a travel lane, it is possible that vehicles
will be detected that are
not in the lane

Faults in the brake system
If you should notice a sudden increase in
brake peda l travel, t hen one of the two bra ke
circ uits may have failed ¢.&. .
Low brak e flu id le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low . T he brake fluid
l eve l is monitored electronically .
Bra ke boo ster
The brake booster increases the pressure that
you generate w ith the brake pedal. It only op­
erates while the eng ine is running ¢,&. .
Brake lining we ar sta tu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spection ¢
page 307, Changing a wheel.
A WARNING
- You should perfo rm bra king maneuve rs
for the p urpose of clean ing the b rake
system on ly if road condit ions permit.
Other road users must not be put at risk -
you may cause an accident!
- Be fore descending a steep grade, reduce
speed and shift transmission 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 braking
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 brakes to
overheat, premature wear and inc reased
stopping distance.
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced . In winter, ice can accumu
late on the brake pads, linings,
discs and drums. Carefully app ly brakes
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
b rake discs and pads with a few ca reful
brake applications.
- If you damage the front spoiler, or if you
i n stall a diffe rent spoiler, be s ure the a ir
f low to the front brakes is not obs truct­
ed . Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system .
- Fai lure of one brake circuit will impai r
the braking capability resulting in an in­
creased stopping distance . Avoid driving
the vehicle and have it towed to the near­
est authorized Audi dea ler or qualified
workshop .
- Never let the ve hicle roll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake peda l must be pressed cons idera­
b ly harder to make up for the lack of
booster assistance.
Servotronic - advanced power steering system
The power steering systems uses the power of
the running engine to allow precise steering
with Little effort.
T he advanced Servotronic power steer ing sys ­
tem senses the road speed and electronica lly
adjusts power assistance to provide comforta­
ble and safe steering response exactly match­
ed to the vehicle speed.
Power s teer ing will not work if the engine is
off. As a result, the steering wheel will be hard
to turn.
T he powe r steering fluid level is checked d ur-
ing the sched uled maintenance services . ..,.

Catalytic converter
Applies to vehicles: with gasoline engine
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
... Always use lead-free gasoline c::> page 248,
Gasoline .
... Never run the tank down all the way to emp­
ty .
... Never put too much motor oil in your engine
c::> page 261, Adding engine oil 't=r..
.,. Never try to push-or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr it ically
i mportant for the life of the cata lytic convert­
e r and proper functioning of the engine.
& WARNING ,~
T he temperature of the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exha ust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
(D Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de-
grade the performance of the catalytic
conve rter.
Dri vin g and en vironm ent 231
-Do not exceed the correct engine oil level
c::> page 261.
- Do not drive until the fue l tank becomes
completely empty. The engine cou ld mis­
fire. Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing.
- Do not continue to operate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle main tained properly
and in accordance w ith the se rv ice rec­
ommendations in your Warranty & Maintenance book let.
- Lack of proper maintenance as we ll as
improper use of t he vehicle will impair
the function of the emission contro l
system and could lead to damage.
@) For the sa ke of the env ironment
Even when the Emission Control System is
operating properly, the exhaust gas can have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank with lead-free s uper
g rade gasoline.
Diesel particulate filter
App lies to vehicles: wit h diese l eng ine
The diesel part iculate filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r clea ns itself automat ica lly under no rma l
driv ing cond itions. If the filter cannot clean it ­
self (for example, because you are on ly driving
short distances), the fi lter becomes clogged
with soot and the
II symbol for the diese l
particulate filter i lluminates

232 Driving and en vironm ent
,8. WARNING
-Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in the exhaust system area or a fire could start.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especia lly true for vehicles with low­
slung chassis (sports chassis)* and fully load­
ed vehicles.
Shutting down vehicle
If you would like your vehicle to remain inop­
erative for a longer period of time, contact an
Audi or other specialized dealer . They can ad­
vise you on necessary precautions e.g . corro­
sion prevention, maintenance and storage. Pay attention to additional information con ­
cerning the battery. Refer to
c::> page 266 .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent . This sec­
tion will give you some tips on how you can help the environment and your pocketbook.
(D Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
· Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac­
celerating.
., Avo id unnecessary accelerating and brak ing .
Vehicles use the most fuel when they are ac ­
celerating . If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
., Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the environment.
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit.

Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at rail­
road cross ings, or at traffic lights that have
long waits on red. Turning the engine
off for
just 30-40 seconds saves more fuel than is
burned starting the engine again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting. If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
11-Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects fuel
consumption.
Check your oil each time you fill your tank.
Driving and environment 233
The amount of oil used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(S,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
t enance booklet. Lack of prop er mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission cont ro l system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
11-Try to avoid driving short distances w ith a
cold engine.
T he engine and cata lytic converter have to
reach their optimal operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/l00km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km), liJI,

Gasoline additives
Applies to vehicles : wit h gasoli ne e ng in e
A majo r concern among many auto manufac­
ture rs is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
Fuel supply and filling your fuel tank 249
brands include additives to keep engine and
fuel systems clean, they are not equally effec­
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
webs ite (www.toptiergas.com).
After an extended per iod of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
CD Note
Damage or malf unct ion due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diesel engine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2. The ULSD No. 2 meets the ASTM D97S.
Diesel fuel with concentrations of biodiesel
highe r than S % such as Bll, B2O or BlOO are
strictly prohib ited .
Se rv ice stat ion fuel pumps are labeled with
the cor rect fuel informat ion for easy recogn i­
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries .
ULSD No. 2 can become thicker in very cold
temperatu res, and this can impair the en­
gine's start ing and running. Depending on the
season, gas stations provide ULSD No. 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usua l.
CD Note
-Yo ur vehicle's diesel engine was de­
signed soley for use with ULSD No. 2.
Therefore, never use gasoline, heating oil, other fuels or flow improvers. These
conta in substances that will severely
damage the fuel system and the engine . .,.

252 Fuel supply and filling your fuel tank
addition, the expans ion space in the fuel
tank will be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
@ Tips
- Running your engine while refuelling
may cause vapors to escape or even
cause fue l to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle w ith the igni­
tion turned on. The fuel gauge may oth­
erwise not ind icate the correct fuel level
after refuell ing.
- Diesel veh icles* are equipped with a die­
sel misfueling protector. It allows the
vehicle to be fueled only w ith a diesel
fuel pump nozzle. A worn or damaged
nozzle or a nozzle that is too small may
not be able to open the diesel misfueling
protector. If this is the case, try turning
the nozz le before inserting it in the fue l
filler neck, use a different fuel pump or
see your authorized Audi dealer or au­
thorized repair facility for assistance.

Selective catalytic
reduction
General information
Applies to vehicles: with diesel engine
On vehicles with selective catalytic reduction,
an urea solution (AdBlue) is injected into the
exhaust system before a nitrogen oxide cata­
lytic converter to reduce nitrogen emissions.
The Ad Blue is stored in a separate tank in the
vehicle. The Ad Blue usage accounts for ap­ proximately 0.5% to 1.2% of the diesel fuel
that is used .
You must refill the Ad Blue or have it ref illed
by your authorized Audi dealer or qualified
workshop as soon as the Ad Blue refill mes­
sage appears in the instrument cluster
¢page 254.
&_ WARNING ~
Failure to heed AdBlue refill information in
the instrument cluster can prevent the ve­
hicle from being started and dr iven.
If the
vehicle cannot be driven and an emergency
arises, personal injury can occur.
- Always have the AdBlue tank refilled we ll
before the tank runs dry. .,.
