2009 AUDI A4 CABRIOLET fuel consumption

Tires and wheels -
----------------
•
• The tire pressures should only be checked and adjusted when
t he t ires are co ld . The s lightly raised press ures of warm tires must
not be reduced .
• Adjust t he tire p re ssure to the load you are carrying.
• Reinstall the va lve stem cap on the valve.
When should I check the tire pressure?
The correc t tire p re ssur e is espec ially i mportant at high speeds. The
pressure should there fore be c hecked at least once a month and
a lways before starting a journey. Do not forget to check the tire pres ­
su re for t he spare whee l::::>
page 291.
When should I adjust the tire pressures?
Adjust the ti re pressur e to the load you are carrying. A fter chang in g
a wheel
or replacing whee ls you have to adj ust t he t ire pressure s on
a ll whee ls. In addition, o n ve hicles w ith t ire pressure monito ring
system * you must then store the new tire pressures in the system
=> page 41.
& WARNING
Incorrect tire pres sures and /or underinflation can lead sudden tire
failure, loss of control , collision, serious personal injury or even
death .
• When the warning symbol ( appears in the instrument
cluster , stop and inspect the tires .
• Incorrect tire pressure and /or underinflation can cause
increased tire wear and can affe ct the handling of the vehicle and
stopping ability .
• Incorre ct tire pressures and /or underinflat ion can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehi cle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle . The appli cable pre ssure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
& WARNING (continued )
• Only when all tires on the veh icle are filled to the correct pres­
s ure, the tire pressure monitoring system * can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure monitoring system*.
• Alway s inflate tires to the recommended and corre ct tire pres ­
sure before driving off.
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Excessive speed and /overloading can cause he at build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high , the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest service station
to che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
valves. To p revent this, a lways make sure tha t factory installe d va lve
stem caps on al l wheels are securely mounted on the va lve .
<£> For the sake of the environment
Underinflated tires wi ll a lso increase the fue l consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehic le and
any tire can carry. A vehicle that is overloa ded wil l n o t handle well _,.
