Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 196 Eng ine compartment: cover on the coolant
expansion tank
Before you check anything in the engine com­
partment,
alwa ys read and hee d all W ARN­
ING S ¢.&. in Working in the engine compart­
ment on page 22
7 .
.,. Park your vehicle on a level surface.
.,. Switch off the ignit ion.
.,. Read the engine coolant level from the cool­
ant expansion tank¢
fig. 196, ¢ page 229 ,
fig. 193 .
With a cold engine, the coolant
level should be between the "min" and
"max" mar kings. When the engine is warm,
the leve l may be slightly above the "max"
marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration¢
page 229 .
To obtain an accurate read ing, the eng ine
must be switched off.
The expans ion tank in you r vehicle is equipped
with an electric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto -Check System ¢
page 17 will
illum inate u ntil you add coolant a nd the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolan t leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool-
Checkin g and fillin g 235
ing system should be inspected immediately
by your authorized Audi dealer . It is not
enough merely to add coolant.
In a
s ea led system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by follow ing these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escap ing f lu id and steam by cover ing the
cap with a la rge, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
plyi ng light, downward pressure on the
top of the cap .
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine parts. Under certa in cond i­
tions, the ethylene gly col in engine coo l­
a nt can catch fire.
(D Note
Do not add any type of radiator leak sea L­
ant to your veh icle's engine coo lant . Add­
i ng radiato r repa ir flui d may adverse ly af­
fect the funct io n and performa nce o f your
cooling system and could result in damage
not covered by your New Vehicle Limited
War ranty.
Adding coolant
Be very careful when adding engine coolant .
Before you che ck anyth ing in the eng ine com­
partmen t,
alway s read and heed all WARN­
INGS ¢.&_ in Working in the engine compart­
ment on page

.,. Tur n off the engi ne.
.,. Let the engine cool down.

24 4 T ire s and wheel s
-Never mount used tires on yo ur 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 t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.
(D Note
Please note that summer and winter tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that th ese
items are availab le as factory -installed equip­
ment (whether installed or not) .
Aspect ratio
means t he ratio of the he ight 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 overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typ
ica l in those seasons . Audi recommends
using winter tires during the winter
months . Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very co ld tem­
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un­
balan ced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pressure
means the tire p ressu re recommended by t he
vehicle manufacturer fo r a tire of a des igna ted
s iz e that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
t h e three hour period before the tire pressure
is measured or adjusted.
Curb weight
mea ns the we ight of a motor ve hicl e w ith
standard equipment including the max imum
capacity of fuel, oil, and coolant, air condi ­
tioning and additional weight of optiona l
equipment.
Extra load tire
me ans a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -c a rry ing c apac ity of a s ingle
axle system , measured a t the tire-ground in­
terfaces.
Gross Vehicle Weight Rating ("GVWR ")
mea ns the maximum total loaded we ight of

chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severe ly dam­
age the wheelhouse and other parts of
the veh icle.
(D} Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory installed r ims. If different rims
are fit­
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
¢page 287.
_& WARNING
Imprope rly tig htened o r maintained whee l
bolts can be come loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bol ts an d the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be prop­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintain the correct tighten ing
torq ue for the wheel bo lts to reduce the risk of a whee
l loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tighte ning torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be­
come loose.
([) Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torque whee l bolts diago­
nally. Afte r changing a whee l, the torque
must be checked as soon as possible wi th a
torque wrench -pre ferably by an au thor­
ized Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and hand ling u nder a var iety of d riv ing condi ­
t ions . As k your author ized Audi dealer for
more details.
The low aspect ratio of these tires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral rep resents the ratio
of the t ire's s idewa ll height in relation to its
t read width ex pressed in percentage. Conven­
t iona l tires have a he igh t/w idth rat io of 60 or
more.
The performanc e of low -a sp ec t-ratio tires i s
pa rticularly sensitive to improper inflation
pre ssure . It is therefore important that low
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure i s
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 249, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w ith potholes, curbs, gull ies .,..
