ECO mode AUDI S6 2009 Service Manual

Tires and wheels -
----------------
•
The correct tire pressure for the spare wheel is located on a label on
the driver's side 8 -pillar.
Because technical changes may be made to vehicle equipment
during the mode l year, always compare the tire size designation on
the tire pressure label on your vehicle with the tires on your vehicle.
Make sure that the tire size information on the vehicle label is the
same as the size of the tires on the vehicle. This is especially impor­
tant if the vehicle belongs to someone else or you bought the
vehic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers also depends
on making sure that load l imits are not exceeded. Vehicle load
includes everybody and everything in and on the vehicle . These load
limits are techn ically referred to as the vehicle's Gross Veh icle
Weight Rating ("GVWR"l. The Gross Axle Weight Rating ("GAWR"l is
the maximum load that can be applied at each of the vehicle's two
axles. The Gross Vehicle Weight Rating and the Gross Axle Weight
Rating are listed on the safety compliance sticker label located on
the driver's side 8-pillar. The tire pressure label on your Audi lists
the maximum comb ined weight of all of the occupants and luggage
or other cargo that the vehicle can carry. For the location of the tire
pressure label =>
page 327, fig. 247.
& 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 designed to carry
will prevent the vehicle from handling properly and increase the
risk of a 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
causing loss of control and a crash.
& WARNING (continued)
• 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 .
& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
serious or fatal accident.
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
on driver's side 8-pillar.
The recommended tire pressures are on the tire pressure label and
in the table=>
page 327, "Cold tire inflation pressure". This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of mi les (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as it flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold ."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Cold tire inf lation
pressure" recommendations=>
page 327. The tires wou ld then be
underinflated and could fail suddenly. .,_

Tires and wheels -_______________________ ..::...:..:..-=::.......:.:..;::..:....____;___
•
Wheel bolts
Wheel bolts must always be tightened to the correct
torque.
The design of wheel bolts is matched to the factory installed rims. If
different rims are fitted, the correct wheel bolts with the right length
and correctly shaped bolt heads must be used. This ensures that
wheels are fitted securely and that the brake system functions
correctly.
In certain circumstances, you may not use wheel bolts from a
different vehicle - even if it is the same model~
page 374.
& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss.
If the tightening torque of
the wheel bolts is too low, they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel bolts and threads can be damaged and the wheel can become
loose.
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
tolerance of ± 7,4 ft lb(± 10 Nm). Torque wheel bolts diagonally.
After changing a wheel, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under
a variety of driving conditions. Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of 55 or
less in the tire's size designation. The numeral represents the ratio
of the tire's sidewall height in relation to its tread width expressed
in percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 323, "Checking tire pressure" .
What you can do to avoid tire and rim damage Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehicle, we recommend that you observe the following
precautions:
• Always maintain recommended inflation pressures . Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes, deep gullies or ridges.
The impact from driving through or over such obstacles can
damage your tires. Impact with a curb may also cause damage to
your tires. ..,

& WARNING
Always read and follow all WARNINGS and information => & in
"Raising the vehicle" on
page 347 and => page 349. •
After changing a vvheel
A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
-Check the tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
replaced as soon as possible.
[ i] Tips
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Drive at reduced speed until you have the tightening torques
checked. a
