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
c::;, page 12.
8
(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.

A WARNING
-- 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.
