(1) Note
Never drive with the tan k completely emp
ty. An irregu la r fuel supp ly can ca use the
eng ine to misfire. This leads to uncom
busted fuel in the exhaust system. This
can cause overheating and damage to the
catalyt ic converter.
Engine coolant temperature gauge
The engine coolant temperature gauge@
¢
page 10 , fig . 3 only functions when the ig
n ition is switched on . To prevent engine dam
age, observe the follow ing important points
concerning the temperature ranges.
Cold r ange
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high eng ine speed, full
throttle, and heavy eng ine load.
Norm al ra nge
The engine has reached its operating temper
ature once the LEDs up to the center of the
gauge turn on under normal driving condi
tions . The LEDs higher up may turn on when
the eng ine is under heavy load or the exter ior
temperature is high . Thi s is not a cause for
concern as long as the. indicator light in
the disp lay does not turn on .
Hot range
If the LEDs in the upper area of the display
and the. indicator light in the instrument
cluster display turn on, the coolant tempera
ture is too h igh ¢

A WARNING
-Always observe the warn ing in
¢
page 210 before opening the hood
a nd checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment .
You could bur n yourself. Let the engine
coo l off first u ntil yo u can no longer see
or hear steam or coolant escaping.
([) Note
-Add itional headlights and other compo
nents in front of the a ir intake reduces
affect of the eff iciency of the coolant. At
hig h ou tside air temperat ures and wi th
heavy eng ine load, there is a ris k of the
eng ine overheating .
- T he front spoiler ensures the correct dis
tribution of cooling air while driving . If
the spoi ler is damaged, the effect of the
coolant can be reduced and there is a risk
of the engine overheating. See your au
thorized Audi dealer or qualified repair
facility .

226 Tire 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.

- Please note that summer and winter
tires are designed for the cond itions that

Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those standard items which may be rep laced)
of automatic transmission, power steering,
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).
A spect ratio
means th e ratio of the height to the width of
the tire in percent. Numbers of 55 or lower in
d icate a low sidewall for improved steer ing re
sponse and better overall handling on dry
pavement .
Bead
means the part of the tire th at is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a breakdown of the bond between
components in the bead.
Cord
means t he strands forming the plies in the
tire. ter months.
Low tempe ratu res signifi
cantly decrease the elasticity of summer
tires, which affects traction and braking ability. If summer tires are used in very
co ld temperatures, cracks can form on
the tread bars, resu lting in permanent
tire damage that can cause loud driving
noise and unbalanced tires. Aud i is not
responsib le for this type of damage.
- Burn ished, polished or chromed rims
must not be used in winter weather. The
surfa ce of the rims does not have suff i
c ien t cor rosion prote ct io n for this and
co uld be pe rmanen tly damaged by road
salt or simi lar substances. This damage
is not cove red by war ranty.
Cold tire inflat ion pre ssure
mea ns the t ire press ure recommended by the
vehicle manufacturer for a tire o f a des ignated
size that has not bee n driven for more than a
coup le of miles (ki lometers) at low speeds in
the three hour period before the tire press ure
is measured or adjusted.
Curb weight
means the weight of a motor vehicle w ith
standard equipment including the maximum
capacity of fuel, o il, and coolant, air condi
tion ing and additional weight of optional
equipment.
E x tra load tire
means a tire design to operate at higher loads
and at higher inflation pressures than the cor
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR")
means the load-carrying capacity of a single
axle system, measured at the tire-ground in-
terfaces.
