brakes AUDI Q7 2011 Owner´s Manual

& WARNING (continued)
• Carrying more weight than your vehicle was designed 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 distance.
• Tires on a vehicle that has been overloaded 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 -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating. •
Determining correct Load Limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to transport so
that you can make sure that your vehicle
will not be overloaded.

Steps for Determining Correct
Load Limit
1.Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehicle's placard (tire infla­
tion pressure label)==>
page 322,
fig. 241.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker==>
page 322, fig. 241.
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5
X 150) = 650 lbs.) •

T ires with the ident ificat ion "AO" or "RO" have been specially

because t hey meet the hig hest standards regard ing safety a nd
dr iving charac teris tics when used corre ctly. Your aut horize d Aud i

Tire ply composition and materials used
T he number of p lies indicates the number of layers of rubber-coated
f abr ic in the tire. In ge ne ral, the greate r the numbe r of p lies, the
more weig ht a tire ca n support. Tire manufac turers also mus t indi­
c ate the materials in the t ire, which incl ude stee l, nylon, polyes ter,
and others .
Maximum Load Rating
This number ind icates the maximum load in k ilograms and pounds
t ha t can be carried by the tire .

temperature resistance

Maximum Permissible Inflation Pressure
Th is number is the greatest amount o f air press ure t hat should eve r

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control , collis ion
and seriou s personal injury.
& WARNING (co ntinued )
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that have been specifically app roved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that a re 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
eventhoughthedamagecannotbeseenthatcanleadtosudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type , size (rolling circumference) and the same tread pattern.
Driving with different tires reduces vehicle handling and can lead
to a loss of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for example with winter tires - only use the spare
tire for a short period of time and drive with extra care . Refit the
no rmal road wheel as soon as safely possible .
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Ove rloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or underinflated.
• For technical rea sons it is not always possible to use wheels
from other vehicles- in some cases not even wheels from the same
vehicle model.
• If you install wheel trim discs on the veh icle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopp ing distances
and causing a colli sion.
