Coolant temperature indicator
The coolant temperature display c;, page 8,

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

(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. ..,.

@ 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.

!?) Engine speed limitation
Applies to: vehicles with engine speed limitation
(II Maximum engine speed : XXXX rpm
The engine speed is automatically lim ited to the
speed d isplayed in the driver information system .
This protects the engine from overheating .
The engine speed limitation deactivates once the
engine is no longer in the critical temperature range and you have released the accelerator ped­
a l once.
If the engine speed limitation was activated by
an engine control malfunction, the
rl indicator
light also turns on. Make sure the engine speed
does not go
above the speed d isplayed, for exam­
ple when downsh ift ing. Drive to an autho rized
Aud i dealer o r authorized Aud i Service Facility im ­
mediately to have the malfunction corrected.
~. Engine oil level (MIN)
Applies to: vehicles with oil level warning
Ill Please check oil level
You may continue driving for the time being.
Check the engine oil leve l as soon as possible
r=> page236.
-If the engine oil level is too low, add engine oil
r=>page 237.
-If the engine oil level is correct and the ind ica­
tor light still turns on, drive at low eng ine
speed to an authori zed A udi dealer or autho r­
ized Audi Serv ice Facility.

tact Service
The sensor to check the engine oil level has
failed. Drive to an authorized Audi dealer or au ­
thorized Audi Service Facility immediate ly to have
the malfunction corrected .

If the indicator light turns on for the first time
and the message appears, there are about 1.9
gal (7 L) of fuel left in the tank.

If the indicator light turns on the message ap­
pears, the fuel tank is almost empty. Refue l the
vehicle immediately.

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
l oad and speed, road and weather cond itions,
