2013 AUDI S4 coolant capacity

(D Note
Never use a fast charger as a booster to
start the engine . This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc ., as well
as the battery charger .
Battery replacement
The new battery mu st have the same specifi­
cations and dimensions as the original equip­
ment battery .
Intelligent energy management in your vehi­
cle is responsible for d istributing the electr i­
cal energy throughout your vehicle
c::>
page 192. The intelligent energy manage­
ment system w ill keep the engine battery
charged bette r then vehicles w ithout t his sys­
tem. To make sure the additional electr ica l en­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and manu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the bat tery hous ing. Your
author ized Audi dealer must code the battery
in the energy management system to enable
you to use the energy management functions
correctly after replac ing the battery .
If it is not possible to use a battery of this
type, the new battery must have the same ca­
pac ity, voltage (12-volts), amperage, con­
struction and plug sea ling.
When insta lling the battery, make sure the ig ­
nition and all electr ical consumers are turned
off.
(D Note
Make sure the venti lation hose on the s ide
of the battery is connected , othe rwise
fumes or battery ac id can leak out .
@ For the sake of the environment
Because of the problem of proper d isposal
of a battery, we recommend your author­
ized Aud i dealer change the battery for

you. Batteries contain sul fur ic acid and
l ead and must always be disposed of prop­
erly in comp liance with a ll environmental
regulations. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi­
ronment .

-Never mount used tires on yo ur vehicle if
yo u 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.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

Glossary of tire and loading terminology
Accessory weight means the comb ined weight (in excess of
those sta ndard items which may be rep laced)
of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overa ll handling on dry
pavement .
Bead
means the part of the t ire t hat is made o f
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead .
Cord means the strands forming the plies in the
tire.

typica l in those seasons . Aud i recommends
using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem ­
peratures, cracks ca n form o n the tread
bars , res ulting in perma nen t tire damage
that can cause loud driving noise and un­
bala nced ti re s. Audi i s not respon sible for
th is type of damage .
Cold tire inflation pressure
means the t ire p ress ure recommended by t he
vehicle manufacture r fo r a tire o f a des ignated
s ize t hat has not bee n driven for more than a
coup le o f miles (k ilometers) at low speeds in
the three hour period before the tire press ure
is m easured or adjusted.
Curb weight
me ans the we ight of a motor ve hicle with
st andard equipmen t incl ud ing the max imum
capacity of fuel, oi l, and coolant, air condi ­
tioning and additional weig ht of optiona l
equipment.
Extra load tire
means a t ire design to oper ate a t higher load s
and at higher inflation pressures than the cor­
responding standa rd tire . Extra load tires may
be identified as "XL", "x l", "EXTRA LOAD", o r
"RF" on the sidewal l.

not exceeded . Vehicle load includes everybody
and everything in and on the vehicle. These
l oad limits are techn ica lly referred to as the
ve hicle's
Gross Veh icle Weight Rat ing
("GVWR").
The "GVWR" includes the weight of the basic
veh icle, all factory insta lled accessories, a full
tank of fu el, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
in tended to carry ("seating capacity") w ith a n
assumed weight of 150 lbs . (68 kg) for each
passenger at a des igna ted sea ting pos ition
and the tota l we ight of any l uggage in the ve­
h icle. If you tow a trailer, the weig ht o f the
trailer hitch and the tong ue weight of the
l oaded trailer must be included as part of the
veh icle load.
The
Gro ss A xle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two ax les.
The G ross Vehicle We ight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker labe l located on the
driver's side B -pi llar .Your Audi has 5 seating
positions, 2 in the front and 3 in the rear for
tota l seating capacity of 5. Each seating posi­
tion has a seat belt¢
page 137, Safety belts.
The fact that there is an upper limit to your
veh icle's Gross Vehicle Weight Rating means
that the tota l weight of whatever is being car­
ried in the vehicle (including the weight of a
trailer hitch and the tongue weight of the
loaded trailer) is limited. The more passen­
ge rs in the veh icle or passengers who are
h eav ier than the standa rd weights assumed
mean that less weight can be ca rr ied as l ug­
gage.
The tire pressure labe l on you r Audi also lists
the maximum combined we ight of all of the
oc cu pants and luggage o r othe r ca rgo that
the vehicle can carry . For the location o f the

A WARNING
Overloading a vehicle can cause loss of ve­
h icle contro l, a crash or other accident, se­
rious pe rsonal injury, and even death.
- Carrying more we ight than your veh icle
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 w ith in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, incl uding a blowout
and sudden defla tion, causing loss of
contro l and a crash.
- Always ma ke sure that the total load be­
ing transpor ted - incl uding the weight of
a trailer hitch and the tongue weight of a loaded trailer -does not ma ke the vehi­
cle heavier than the vehicle's Gross Vehi­
cle We ight Rating.
Determining correct load limit

culate the total weight of the
pa ssengers and lu ggage or oth­
e r thing s that you pl an t o tran s­
po rt so that you can make sur e
that your vehicle will not b e
o verloaded.
Steps for Determining
Correct Load Limit
