Checking th e brake fluid level
• Read the brake fluid level on the brake fluid
reservo ir
Q page 196, fig. 181. The brake fluid
level must be between the MIN and MAX mark­
ings ~,&. .
The brake fluid level is mon itored automat ically.
Chang ing the bra ke flu id
Have the brake fluid changed regularly by an au­
thorized Audi dealer or authorized Audi Service
Facility .
A WARNING
-If the brake fluid level is be low the MIN
marking, it can impair the braking effect
and dr iving safety, which increase the risk of
an acc ident. Do not cont inue driv ing . See an
authorized Audi deale r or autho rized Aud i
Service Facility for assist ance .
-If the brake f luid is o ld, bubbles may form
in the brake system d uring heavy b raking.
T his would impair bra king perfo rman ce an d
driving safety, which increases the risk of an
accident.
- T o ensure the bra ke system functions cor­
rectly, only use brake fluids that comply
with VW standard 501 14 or FMVSS-116 DOT
4 .
(D Note
- If the brake fluid level is above the MAX
mar king, brake fluid may leak out over the
Chec king and Filling
edge of the reservo ir and result in damage
to the vehicle.
- Do not get any b rake fl uid on the vehicle
paint, because it wi ll co rrode the paint .

Battery acid is highly corrosive. Wear pro-
tect ive gloves and eye protection .
@
Fire, sparks, open flame and smoking are
forbidden .

Checking and Filling
(D Note
If the vehicle will be parked for long periods
of t ime , protect it against the co ld so that it
will not be destroyed by "freezing"

Vehicle battery
The term "vehicle battery " refers to the 12 Volt
bat tery in your vehicle.
Not running the vehicle for long pe riods of
t ime
If you do not drive your vehicle for several days o r
weeks , electri cal equipment is gr adually scaled
back or switched off . This reduces energy use and
ensures the veh icle w ill be able to start after long
periods of time
c::> page 126 . Some conve nience
functions, s uch as interior lighting or power seat
adj ustment, may not be available under certa in
circumstances. These convenience f unct ions w ill
be ava ilab le aga in once you switch the ignition on
and start the engine .
E ven w hen electrica l equ ipme nt is swi tched off,
the equipment can still d rain the vehicle battery
if the vehicle is not driven for long periods of
time . Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery .
The vehicle battery must be charged every month
t o reduce the risk of this happening
c::> page 202.
Contact an author ized Audi dealer or authorized
Aud i Serv ice Facility for more information .
Winter operati on
Cold weather places higher demands on the vehi­
cle battery. This results in reduced start ing abili ­
ty . Have the vehicle battery checked by an au­
thor ized Audi dealer or authorized Audi Service
Facility before the co ld time of year .

The windshield washer reservoir O contains the
cleaning solution for the windshie ld and the
headlight washer
system* ¢ page 196, fig . 181.
The reservoir capacity can be found in
¢page 254.
To reduce the risk of lime sca le deposits on the
spray nozzles, use clean water with low amounts
of calc ium . A lways add window cleaner to the wa­
ter. When the outs ide temperatures are cold, an
anti -freezing agent should be added to the water
so that it does not freeze .
@ Note
-The concentration of anti-freezing agent
must be adjusted to the vehicle operating
cond itions in the respective climate. A con­
ce ntration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­
tives to the washer fluid.
Checking and Filling
- Do not use a glass cleaner that contains
paint so lvents, because t his could damage
the paint.

has reached an inspection or oil change interval
or both intervals at the same t ime, the mes­
sage

- Yellow: the current tire pressure is too low
compared to the specified tire pressure.
The specified tire pressure is the last tire pres­
sure that was stored

Note that the tire pressure also depends on the
temperature of the tire. The tire pressure in­
creases as the engine becomes warmer while
driving.

Only correct the pressure in tires
whose temperature is approximately the same
as the ambient temperature. If the tempera­
ture of the tire is higher than the ambient air
temperature, the tire pressure must be in­
creased approximately 3 PSI (0,2 bar) above
the value on the sticker .

ing devices to alert other motorists .
- Make sur e that passengers wait in a safe
place away from the vehicle and we ll away
from the road and traffic.
236
- To help prevent the vehicle from moving
suddenly and possibly s lipping off the jack,
always fully set the parking brake and block
the front and back of the wheel diagonally
opposite the wheel being changed. When
one front wheel is lifted off the ground,
p lacing the Automat ic Transmission in P
