The fluid level may drop slightly after some time d ue to the auto
m atic adjus tment o f th e b rake pads. This is no t ca use for alarm.
If the brake flu id level falls considerably below the "MIN" mark, the
brake warning/indicator light ( U.S. models:
BRAKE , Canadian mode ls:
ID ) will come on=> page 17 and=> page 30. Do not contin ue to
operate the vehicle. The complete brake system should be thoro ughly
c he cked by an au thor ized Aud i deale r or q ualified works hop and t he
cause corrected. If the brake fluid level is too low, the brake
w ar ning/ind ic a tor ligh t will illum ina te. Con ta ct a n au thori ze d Audi
dealer
immediately .
rn Tips
The brake fluid reservoir is located underneath t he cover. •
Changing brake fluid
Have the brake fluid cha nged b y an experienced tech ni
c ia n.
Brake fluid absorbs mo isture from the a ir . If the water content in the
bra ke fl uid i s too hig h, cor ros io n in th e bra ke system may res ult afte r
a period of time. The boiling po int of the brake fluid will also decrease
cons iderab ly and decrease brak ing perfo rmance .
Th erefo re, th e brake fl uid must be changed
every two years . Always
use new bra ke fluid w hich conforms to Federal Motor Vehicle Stan
dard "F MVSS 1 16 DO T 4".
The brake flu id reservoir can be diffic ult to reac h, therefore, we
recommend that you have the bra ke fluid c hanged by your author ized
Audi dealer . Your dealer has the correct tools, the right brake flu id
and the know -how to do t his for you .
LJ}. WARNING
• Brake fluid is poisonou s. It mu st be stored only in the closed
original containe r out of the reach of children!
& WARNING (co ntinued )
• Brake failure can result from old or inappropriate brake fluid.
Observe these precaution s:
- Use only brake fluid that meets SAE specification
J 1703 and
conforms to Federal Motor Vehicle Standard 116 . Always check
with your authorized Audi dealer to make sure you are using
the correct brake fluid. The correct type of brake fluid is also indicated on the brake fluid reservo ir.
- The brake flu id must be new . Heavy use of the brakes can
cause a vapor lock if the brake fluid is left in the system too
long. This can seriously affect the efficiency of the brakes as
well as your safety. This could result in an accident.
0 Note
Bra ke fluid will damage the paint of your veh icle.
For the sake of the environment
Because of the prob lem of proper disposal of brake fl uid as well as
t he s pecial tool s required a nd the nece ssary ex pert ise, we recom
mend that you have t he brake f lu id changed by your authorized Audi
de aler. •

& WARNING (conti nu ed )
• If the tire i s not flat and you do not ha ve to change a wheel
immediately, drive at reduced speed to the nearest service station
to check the tire pressure and add air as required.
0 Note
Driv ing without valve stem caps can cause damage to the tire valves.
T o preven t this, a lways make sure that fac tory ins talle d valve stem
caps on all wheels are securely mo unted on the valve.

Under inflated t ires will also increase the fuel consumption .•
Tires and vehicle load limits
There are limits to the amo unt of load or weig ht that any vehicle and
any t ire ca n carry. A veh icle th at is overlo ade d w ill n ot handle well and
is more difficult to stop . Overload ing can not on ly lead to loss of
vehicle co ntro l, bu t can also d amage important pa rts of the vehi cle
and can lead to sudden t ire failure, including a b lowo ut and sudden
deflation that can ca use the vehicle to c rash.
Yo ur safety and t hat of your passengers also depends o n mak ing s ure
that load limits are not e xceeded. Vehicle load incl udes eve rybody
and everyth ing in and on the ve hicle. These load limits are tech nically
refer red to as the veh icle's
Gross Vehicle We ight Rating ("GVWR").
T he "GVWR" includes t he weight of the basic vehi cle, all factory
installed accessories, a fu ll tank of fue l, o il, coo la nt and other fluids
plus maxim um load . The maxim um load includes the number of
passenge rs that the vehi cle is intended to car ry ("seating capacity ")
w ith an ass umed we ight of 150 lbs (68 kg) for each pa ssenger at a
designat ed seating position and the tota l w eight of any l uggage in
the vehicle. If you tow a trai le r, the weight o f the t railer hitch and the tongue weight of the
loaded tra ile r must be included as part of the
veh icle lo ad .
T he
Gross Axle Weight Rating ("GAWR ") is the max imum load t hat
can be a pplied at each of the ve hicle's two axles .
Th e Gross Vehicle Weight Rat ing and the Gro ss Axle Weight Ra ting
are listed on the safety compliance s ticker label located on the
dr iver 's s ide B-pillar. Audi h as 4 seat ing pos it ions, 2 in t he fro nt and
2 in the rear for total seating capacity of 4 . Each seating pos it io n has
a seat belt =>
page 189, "Safety belts" .
Th e fa ct t hat there is an upper lim it to your veh icle 's Gross Vehicle
We ight Rating means that the total weight of whatever is being
c arrie d in t he ve hicle (incl uding t he weight o f a trail er hi tch and the
tongue weig ht of the loaded tra iler) is limited . The more passengers
in the veh icle or p assenge rs who are he avier than the st anda rd
we ights assumed mean that less we ight can be carried as luggage.
Th e tire pressure labe l o n yo ur Audi a lso lists the max imum combine d
we ight of alt of the o ccupants and l uggage or o ther cargo that the
vehicle ca n carry . For t he locat ion of the label=>
page 300, fig. 22 7.
& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe di stan ce.
• Tires on a vehicle that has been o verloaded can fail suddenly ,
including a blowout and sudden deflation, causing loss of control
and a crash .
• Always make sure that the total load being transported -
i ncluding the weight of a trailer hitch and the tongue weight of a .,_

Unbalanced wh eels must be rebalanced to avoid e xcessive w ear o n
st eeri ng, sus pens ion and tires. A w heel must a lso be re balan ced
w hen a new tire is installed.
Incorrect wheel alignment
Incorrect whee l alignm ent can ca use excessive ti re wea r, impairing
th e safe ty o f the vehicle. If tir es show excessive we ar, ha ve the w heel
alignment checked by a n authorized A udi dealer or qualif ied wo rk
s hop .
All wheel drive
Vehicle s wi th qu att ro ® mus t alw ay s ha ve tires of the sa m e siz e,
construct ion a nd tread type. For details see~
page 246.
& 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.
• 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 chemicals 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.
• 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. •
