2013 AUDI A4 SEDAN brake fluid

~ Read the brake fluid level from the brake
fluid reservoir ¢
fig. 171, ¢ page 217,
fig . 167.
T he brake fluid level must be be ­
tween the "MIN" and "MAX" markings.
The brake f luid reservoir is located at the rear
partition of the engine compartment on the
l eft side ¢
page 217 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
If the brake fluid level falls considerably be­
l ow the "M IN" mark, the bra ke wa rning/ind i­
cator light (U .S . mode ls:
1111 , Canadian
models: .) will come on
¢ page 15. Do not
continue to operate the vehicle. The complete
brake system shou ld be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause co rrected . If the
b rake fluid level is too low, the b rake wa rn ing/
i nd icator lig ht w ill illuminate . Co ntact an a u­
thor ized Audi dealer immediately.
@ Tips
The brake f luid rese rvoir is located unde r­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experi­
enc ed technician .
Brake fluid ab sorbs moisture from the a ir. If
the water content in the brake fluid is too
hi gh, corrosion in the b rake system may result
after a per iod of t ime . The bo iling po int of t he
b ra ke fluid w ill also decrease con siderab ly and
d ec rease brak ing per forman ce.
Therefore, the brake flu id must be changed
every two year s. Always use new b ra ke fluid
which confo rms to Fede ral Motor Vehicle
S tand ard "FMVSS 1 16 DOT 4".
The brake flu id rese rvoir can be difficult to
r eac h, therefo re , we recommend that yo u
have the brake fl uid changed by yo ur aut ho r­
iz ed Audi dealer. Your dealer has the correc t
Checking and fillin g 225
tools, the right brake fl uid and t he know -how
to do this for you .
A WARNING
- Brake fl uid is poisonous. It must be stor­
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can res ult from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake fluid th at mee ts SA E
spe cificat ion
J 17 03 and conforms to
Fe dera l Mo to r Ve hicl e Standard 1 16.
Always check with yo ur autho rized Au di
dealer to make sure yo u are using the
correct brake fluid. The c orrect type of
brake f luid is also ind icated on t he
brake f luid reservoir .
- The bra ke fl uid must be new. Heavy use
of the brakes ca n cause a vapor lock if
the b rake fluid is left i n the system too
long. This can se riously affect the effi­
c iency of the b rakes as well as your
safety , T his could result in an accide nt.
(!) Note
Brake fluid will damage the pai nt of your
vehicle.
@) For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired an d th e nec essary exper tise, w e
r ecomme nd that yo u have th e brake flu id
c hanged by yo ur aut ho rize d Aud i dea le r.
Battery
General information
U nder normal operating cond itions, the bat­
te ry in your Audi does not need any ma inte­
nance . With
high outside temperat ures or
lo ng da ily drives we recommend that you have
t h e e lectrolyte leve l che cked by an autho riz ed
A udi de aler or qu alified workshop. The elec­
tro lyte leve l should also be checked e ach time
the battery is charged

238 Tires and wheels
-If the tire pressure is too low or too high,
the tires will wear prematurely and the
vehicle will not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Driving without valve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that facto ry installed
valve stem caps on all wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also increase the
fuel consumption .
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 w ill not handle
well and is more difficult to stop. Overloading
can not only lead to loss of vehicle control,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle . These
load limits are techn ically referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories , a full
tank of fuel , oi l, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs . (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve- hide.
If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the loaded trailer must be included as part of the
vehicle load.
T he
Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker label located on the
driver's side B-pillar.Your Audi has 5 seating
positions, 2 in the front and 3 in the rear for
total seating capacity of 5. Each seating posi­
tion has a seat belt <=>
page 136, Safety belts .
The fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
that the to tal weight of wha tever is being car­
ried in the vehicle ( including the weight of a
tra iler hitch and the tongue weight of the
loaded trailer) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage.
T he tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
label <=>page234 , fig.174.
A WARNING
-Overloading a vehicle can cause loss of ve-
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your vehicle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle with in a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly, incl uding a blowout
and sudden deflation, causing loss of
con trol and a crash .

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their" previous histo ­
ry ." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control. Tires and wheels 241
New tires and replacing tires and wheels
New tires and wheels have to be broken in

-Always make sure the transmission se­
lector lever (automatic transmiss ion) is
in "P" (Park position) or Neutral (manual
transmission) and the park brake is firm­
ly applied.
@) For the s ake of the environment
-Changing the engine settings w ill ad­
versely affect emission levels. This is det­
rimental to the environment and increas­
es fuel consumption .
- Always observe environmental regula­
tions when disposing of old engine oil,
used brake fluid, dirty engine coolant,
spent batteries or worn out tires.
- Undeployed airbag modules and preten­
s ioners might be classified as Perchlo­
rate Material -spec ial handling may ap­
ply, see www.dtsc.ca .gov/hazardous­
waste/perch lorate. When the veh icle or
parts of the restraint system including
airbag modules safety belts with preten­
sioners are scrapped, all app licable laws
and regulations must be observed . Your
authorized Audi dealer is familiar with
these requirements and we recommend
that you have your dealer perform this
serv ice for you .
