@ 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.

@ Note
- Before the start of winter, have an author­ ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. Th is is especially important
when driving in co lder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive . You cou ld damage the en­
gine.
If t his happens, only use wate r and re­
store the correct mixture ratio with the
specified coolant additive as soon as possi­
ble .
- Only refill with new coo lant.
- Radiato r sealant must not be mixed w ith
the coo lant .
Adding coolant

Observe the safety precautions c:::> page 233 ,
Working in the engine compar tment.

~ 0 > 00 ID
.. Read the coolant level on the coolant expansion
tank
c:::> page 236, fig. 180 . The coolant level
must be between the markings when the en­
gine in cold. When the engine is warm it can be
slightly above the upper mark ing .
Adding coo lant
Requirement : there must be a residual amount of
coolant in the expansion tank

.. Let the engine cool down.
.. Place a clot h over the coolant expansion tank
cap and unscrew the cap counterclockwise

.. Add coo lant mixed in the correct rat io
c:::> page 239 up to the upper marking .
.. Make sure that the fluid level remains stable.
Add more coolant if necessary .
.. Close the cap securely .
Coolant loss usually ind icates there is a leak. Im­
mediate ly dr ive your vehicle to a n author ized
Audi dealer or author ized Audi Service Fac il ity
and have the cooling system inspected. If the
cooling system is not lea king , a loss can come
from the coolant boiling through overheat ing
and being pushed ou t of the cooling system .
Lil WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion tank cap
when the engine is hot. This increases the risk of burns.
-The coolant additive and the coolant can be dangerous to your health. For this reason ,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
-When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched
off, wh ich
increases the r is k of injury.
@ Note
Do not add coolant if the expans ion tank is
empty . A ir could enter the cooling system and
-
damage the eng ine . If this is the case, do not ..,.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout

Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number
