Working in the engine compartment
Special care is required if you are working in
the engine compartment
F o r w ork in th e engine co mpartm ent such as
c h ec king an d filling fluids, there i s a ri sk of
inj ury, sca lding, a ccid ent s, and b urn s. For
t hi s re ason , fo llow all th e followin g lis te d
warn in gs a nd ge neral safe ty pr eca utions.
Th e e ngine compartment is a d ange rous
area .¢ .& .
&_ WARNING
To reduce the risk of injury, before you
check anyth ing under the hood:
- Turn the engine off.
- Set the parking brake.
- Place the selector leve r in the P position.
- Remove the ignit io n key .
- Let the engine coo l down.
- To reduce the r isk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or hea rd before ca re­
fully opening the hood.
- Keep chi ldren away from the engine com­
partment .
- Never spill flu ids on a hot engine. These
fluids (such as the freeze protection con­
tained in the coolant) can catch fi re.
- Avoid short circuits in the electrical sys­
tem, especially the battery.
- When working in the engine compart­
ment, remembe r that the radiator fan
can switch on even if the ignition is
switched off, which increases the risk of
persona l injury . -
Never open the cap on the coolant ex­
pans ion tank when the eng ine is warm.
The coolant system is under pressure.
- To protect your face, hands, and arms
from hot steam or coolant, cover the cap
with a large cloth when opening.
- Do not remove the engine cover under
any circumstances . This increases the
risk of burns .
- If tests need to be performed with the
engine runn ing , there is add itional dan­
ger due to moving components (such as
the ribbed belt, generator and radiator
fan) and from the high voltage ignit ion
system.
- Never touch the rad iator fan . The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Pay attention to the fo llow ing warnings
listed when wo rk on the fuel system or
on the e lectr ica l equipment is req uired.
-A lways disconnect the vehicle battery
from the vehicle electr ical system
- Do not smoke
- Never work near open flames
- Always have a wo rk ing fire exting uisher
nearby
- To avo id e lectr ica l sho ck and pe rsonal in­
jury whi le the engine is running or being
started, never touch:
- Ign it ion cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the eng ine running:
- First, fully app ly the parking brake,
move selector lever to P (Park).
- Always use extreme caut io n to prevent
cl othing, jewelry, or long hair from get­
ting caught in the radiator fan, V-be lts
o r other moving parts, o r from contact­
ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards¢,& . ..,.

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.
(D Note
- Please note that summer and winter
tires are designed for the cond itions that
a re typ ica l in those seasons. Aud i recom­
mends using w inter t ires d uring the win-
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.
IJ>,

-Only when all tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring system can work cor­ rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specif ied tire pressure values
for the tires and the co rrect p ress ures for
the f unction of t he tire pressure mo nitor­
ing system.
- Always inflate ti res to the recommended
and co rrec t tire pressu re befo re d rivi ng
off.
- Drivi ng with under inflated ti res bend
more, letti ng them get too ho t res ulting
in t read separation, sudden t ire fail ure
and loss of control.
- Excessive spee d and/ove rloading can
cause heat bui ld -up, sudden tire fa il u re
and loss of control.
- If the t ire pressure is too low or too high,
the tires w ill wea r prematurely and the
vehicle will not hand le we ll.
- If the t ire is no t flat and you do no t have
to change a w heel imme diate ly, 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 va lve stem caps ca n cause
damage to the t ire va lves. To prevent this,
always make s ure that facto ry installed
valve stem caps on all wheels a re secure ly
mounted on the va lve .
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can carry .
A vehicle that is ove rloaded w ill not ha ndle
well and is more difficult to stop . Overload ing
can no t on ly lead to loss o f vehicle con tro l,
Tire s an d wheel s 233
but can also damage important parts of the
vehicle and ca n lead to sud den tire fai lure, in ­
clud ing a b lowout and s udden def lation that
can cause the vehicle to cras h.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
Gross Vehicle We ight Rating
("GVWR ") .
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coo lant and other fluids plus
maximum load . The max imum load includes
the number of passenge rs that th e vehicle is
i n tended to car ry ("seat ing capa city") wi th an
ass umed we igh t of 150 lbs (68 kg) fo r each
passenger at a designated seating posi tion
and t he tota l weight of any luggage i n the ve­
hicle . If you tow a trai ler, the weight of the
tra iler hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
T he
Gro ss 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
G ross Axle Weig ht Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar. Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rea r for
total seating capacity of 5 . Each seating posi ­
t ion has a safety belt
~ page 131, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
t h at the total weight of whatever is bei ng car­
ried in the vehicle ( in cl ud ing t he weight of a
t ra ile r hi tc h a nd the tongue we ight of t he
l o ad ed tr ailer) is lim ited. The more p assen­
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug -
gage.

- The vehicle capacity weight figures apply
when the load is distributed evenly in the
vehicle (passengers and luggage). When
transport ing a heavy load in the luggage
compartment, carry the load as near to
the rear axle as poss ible so that the vehi­
cle's handling is not impaired .
- Do not exceed the maximum permissible axle loads or the maximum gross veh icle
