• Be aware of the different than usua l steering response and
adjus t you r steer ing forc e acc ordin gly.
• Have the prob lem checked and set right by an Audi dea ler as
s o on as poss ible.
[ i] Tips
• When t he engi ne is running, never ho ld t he steer ing w heel
turned all the way to the right or to the left for longer than 15
seco nds. Th e powe r steering p ump w ill ove rhea t th e hydra ulic flu id
if you keep holding the steer ing whee l turned a ll the way . T his is
l ike ly to d amage t he powe r stee ring sys tem.
• I f the power steering system should fail entirely, or if the engine
i s not r unning ( for e xa mpl e, while being t owed), you will still be able
to steer the vehicle . However,
considerably more effort wil l be
r e q uired to do s o.
• I f the power steering system should have a lea k, or is not func ­
t ioning pr operly, co nt ac t yo ur auth orize d Audi deale r immedia tely.
• T he power steering system requires a specia lly formu lated
h ydraulic fluid. T he power s teeri ng reserv oir is th e one loca ted m ost
forward on the left side of the engine
compartment=> page 265,
"Engine co mpartme nt". The c orrect f luid level in the reservoir is
important for proper functioning of the power steering .•

With All W heel Dr ive, powe r is d istributed to all four w hee ls . T hi s
happens automatica lly depending on your dr iving style and the

Winter tires
When driv ing in th e win te r, yo ur ve hicle with All Wheel Drive ha s an
advantage, even with regular t ires. In winter road conditions it may
b e advi sable to m ount win ter tires ( or all -s easo n tires) for impr oved
driveabi lit y and braking : th ese tires mus t be moun ted on
all four
wheels .

Replacing wheels /tires
Ve hicles wit h All Wheel D rive mu st always have t ires of the sa me

Off-Road dri ving?
Yo ur Au di d oes not have e nough gr ound clea ra nce to be use d as an
off -road vehic le . It is therefore best to avoid rough tracks and
u neven te rr ain as much as poss ible . Also refe r
to => page 2 45.
& WARNING
Alway s adjust your driving to road and traffic condition s. Do not
let the extra safety afforded by the all -wheel drive tempt you into
taking extra risks .
• Although the quattro ®all-wheel drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at e xcessive speeds on icy or slippery
road surfaces.
• On wet road surfaces , be careful not to drive too fast be cause
the front wheels could begin to slide on top of the water (hydro ­
planing ). If this should occur , you will have no warning from a
sudden increase in engine speed as with a front -wheel drive
vehicle . Always drive at speeds which are adjusted to the road
conditions - risk of crash! •

_ d_ w_ h_ e_ e_ls _________________________________________________ _
&, WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead means the part of the tire that is made of steel wires, wrapped or
reinforced by ply cords and that is shaped to fit the rim.
Bead separation
means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
&, WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
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 driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage.
•
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted .
Curb weight
means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire designed to operate at higher loads and at higher infla ­
tion pressures then the corresponding standard tire. Extra load tires
my be identified as "XL", "xi", "EXTRA LOAD", or
"RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire-ground interfaces .
Gross Vehicle Weight Rating ("GVWR")
means the maximum total loaded weight of the vehicle.

Rotating tires for more even wear
For all four tires on your vehic le to have the same service life, we

tire manufacturer 's suggested tire rotation interva ls. Please

• Ti re rotation interva ls m ay d iffer from th e vehic le servic e inter ­

Wheel balancing
T he wheels on n ew vehic les are bala nced. However, various situa ­
tions during eve ryday driving can cause them to become unba l­
ance d, res ulting i n vi brat ions you ca n us ual ly f eel thro ugh t he
steering whee l. U
nba lanc ed wh eels must be rebalanced to avoid excessive wear on
s tee ring, s uspen sio n an d tir es. A w heel m ust also be reba la nced
when a new tire is install ed.
Incorrect wheel alignment
Incorrect whee l alignment can cause excessive tire wear, impairing
t he sa fety o f the vehicl e. If ti res sh ow ex cessiv e w ear, h av e the
whee l al ignm ent check ed by an autho riz ed Aud i d eal er or qualifi ed
w ork shop.

see=> page 242 .
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators .
• Especially in wet and slick driving situations , a preferably large
profile depth of the tires is necessary , and an approximately
similar profile depth of the front and rear axle tires.
• The diminished driving safety , caused by too small of a tire
profile, is negatively perceivable especially in handling , in danger
of hydroplaning when driving through deep puddles and ponds,
when driving around curves , and in braking behavior.
• 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 chem icals that can cause tire damage , such as
grease, oil, gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
