CD only functions when the ignition is
sw itched on. To prevent engine damage, p lease
observe the following notes about the tempera­
ture ranges.
Cold range
If on ly the LEDs in the left area of the gauge turn
on, the engine has not reached operating tem­ perature yet. Avoid high engine speeds, full ac­
celerating and heavy engine loads .
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on. If
the . indicator light in the Infotain­
ment system display turns on, the coolant tem­
perature is too high
c::;, page 12.

(I;} Note
-Aux iliary head lights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en ­
gine load.
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating w ill increase. See an authorized
Audi dealer or author ized Audi Service Fa ­
cility for assistance .
Fuel level
The indicator@ only func tions when the ignition
i s sw itched on. If the fuel level drops below 1.9
gal (7
L), a red LED will light up and the rD indi­
cator light will turn on
c::;, page 15. The LED
blinks red when the fuel level is very low.
The fuel tank capacity of your veh icle is listed in
the
Technical Data section c;, page 288. ..,.

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
@ Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom­
busted fuel will then enter the exhaust sys­
tem. Th is can cause overheating and damage
to the catalytic converter.
Indicator lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
functions.
With some indicator lights, messages may ap ­
pear and warning signals may sound. The indica ­
tor lights and messages in the display can be cov­
ered by other displays. To show them again, se­
lect the tab for indicator lights and messages us­
ing the multifunction steering wheel
¢ page 17. If there are several malfunct ions,
you can display them one at a time us ing the
thumbw heel.
Some ind icator lights in the d isplay can display in
several colors .
Overview
Some indicator lights turn on briefly as a function
check when you switch the ign ition on. These sys­
tems are marked with a
./ in the following tables.
I f one of these indicator lights does not turn on,
there is a ma lfunction in that system.

-- Read and follow the warnings in
¢ page 233, Working in the engine com­
partment
before opening the hood and
checking the brake fluid level.
- If the brake system indicator light does not
turn off or it turns on while driving, the
brake fluid level in the reservoir is too low,
and this increases the risk of an accident .
Stop the vehicle and do not continue driv­
ing. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- If the brake system indicator light turns on
together with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
be malfunctioning. Functions that stabilize
the vehicle are no longer available. This
could cause the rear of the vehicle to
swerve, which increases the risk that the ve­
hicle will slide. Drive carefully to the nearest
authorized Audi dealer or authorized Audi
Service Facility and have the malfunction
corrected.

Avoid full acceler ation
You sho uld rare ly t rave l a t t he maxim um vehicle
speed . High speeds cause a disproportionately
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the eng ine, for example when
at ra ilroad crossings or traffi c lights w ith longer
red lights . Stopping the engine for 30 -40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
I t takes a very long time in idle to wa rm the en­
gine up to operating tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, you should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Hav e ma intenanc e performed r egularly
By having maintenance performed regu lar ly on
your vehicle, you can he lp to reduce fuel con ­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term va lue but al­
so impacts
fu el con sumpt ion .
A poorly maintained engine can lead to fuel con ­
sumpt ion that is 10% higher than norma l.
A lso check the
o il l evel when refueling . The oil
consumpt ion
depends large ly on the engine load
and speed. It is normal for the oil consumption
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approx imately 3,000 m i (S,000 km) have been
driven.
Avoid short trips
The engine and exhaust clean ing system must
reach their opt imal
op erating temp eratur e to ef­
fective ly reduce consumpt ion and emiss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The eng ine reaches operating
temperature and consumpt ion normalizes only
afte r approx imately
2.5 miles (4 km) .
Driving
@ Note
Do not leave engine idling unattended after
start ing. If warning lights sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle o r other proper­
ty.
@ Note
- Have your ve hicle ma intained properly and
in accordance w ith the service recommenda­
tions i n your Warranty
& Main tenance book­
let. La ck of prope r mai nte nan ce as we ll as
imp rope r use of t he ve hicle will impa ir the
function of the em iss ion cont ro l system and
co uld lead to damage .
- Do not alte r or remove any compone nt o f
t he Emission Contro l System unless ap ­
proved by the man ufacturer .
- Do not alte r or remove any dev ice, s uch as
heat shields, switc hes, ignition wires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
impo rtant ve hicle components.
(D Tips
The cons umption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and T ransport Canada may not co rre­
spond to your actual consumption on the r oad, wh ich w ill vary depending upon veh icle

Driving
When parking on a level surface, simply place the
selector lever in the "P" position. On inclines, ac­
tivate the parking brake first and then move the
selector lever to the "P " position
c> page 61 . This
prevents the locking mechanism from being
loaded too heavily and will make it easier to
move the selector lever out of the "P" position.
A WARNING
- The vehicle can roll even when the engine is
switched off .
- Unintended vehicle movement can lead to
serious injuries.
- Never leave your vehicle with the engine
running while in gear . If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- Power is still transferred to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake when the en­
gine is running and the selector lever is in
the "D" , "S" or "R" position or "tiptronic"
mode is selected.
- Do not inadvertently press the accelerator
pedal when the vehicle is stationary. Other­
wise the vehicle will start to move immedi­
ately, even if the parking brake is set . This
could result in a crash .
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running .
- Never engage the R or P selector level posi­
tions while driving. It could cause a crash .
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"ti ptron i c" .
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- If you must stop on an incline, always hold
the vehicle in place with the foot brake or
66
parking brake to prevent it from rolling
back .
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. The
ml indicator light turns on
and a message appears
c> page 68 when
the clutch is overloaded .
- If the engine must run while you are work­
ing in the engine compartment with the
hood open, make sure a gear is not engag­
ed. The selector lever must be firmly in the
P position and locked in place and the park­
ing brake must be set
c> page 233. Other­
wise, the vehicle could begin moving when
increasing the engine speed, even with the
parking brake set.
@ Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­
lected. This can cause the automatic trans­
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in the N
position will damage the automatic trans­
mission because it is not lubricated under
those circumstances.
- The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions such as frequent starts, creeping for a
long time , or stop-and-go traffic . When the
ml or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool
c> page 68.
- Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans­
mission because it is not lubricated
c> page 285, Towing with a tow truck .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is fastened.

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
-The efficiency of the brakes can also be im­
paired by driving for long stretches on roads
covered with salt without using the brakes .
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes severa l t imes .
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are vent ilated proper ly . Otherwise,
the b rake system could overheat, w hich re­
duces the ir effectiveness.
- Failure of a brake c ircuit impa irs b raking
perfo rman ce , which increases brak ing dis ­
tan ce. Avoid d riving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while t he engine is
stopped because this increases the risk of an
accident.
- If the brake booster is not working, you will
have to press much harder on the brake
peda l to compensate for the lack of the
booster.
@ Note
- Never let the brakes "rub" by pressing the
pedal light ly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking d istance and
causes wear.
- Before driving downhi ll a long distance on a
steep h ill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and relieves the brakes . If
you need to brake additionally, brake in in­
tervals and not conti nuous ly .
0) Tips
- If the brake booster is not working, you
must press the brake pedal with much more
fo rce t han normal.
- If you retrofit your vehicle with a front spoil­
er, whee l covers o r similar items, make sure
t h at the a ir flow to the front whee ls is not
i nte rru pted. Ot herw ise the brake system
ca n become too ho t.
