Tires and wheels -________________ f!ffl
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupant s), you can adjust tire pres sures to
those specified for normal vehicle load . Before operating the
vehicle at maximum lo ad, you must increase the tire p res sures to
those specified for maximum vehicle load=>& .
Bear in mind that the tire press ure monitor ing system can only
mon itor the t ire pressu re s you h ave sto red . T he sys tem does no t
recogn ize the load cond it ion of your vehicle.
Th e effectiveness of t he tire pressu re monitoring system will be
impa ired if you store normal load pressu res but then operate the
vehicle at its maxim um loa d=> & . See the
illustration=> fig. 241 for the location of the label on driver's
side B- pillar (colo r of the act ual la bel and ex act l ocation on the
vehicle will vary slig htly).
N ote that the fo llow ing tab le is accurate at the time of going to press
and is subjec t to change. I n the even t of discrepancies , the tire pres­
sure label located on the dr iver's side B-pi llar a lways takes prece­
dence .

=>
page 340, fig . 250 (D and then insert the locking plate with the
two "tabs" into the elongated holes in the base plate @=>& .
& WARNING
• The chock cannot fulfil its function and may lose its stability if
the "tabs" on the support plate are not inserted correctly into the
elo ngated holes in the base plate. If this happens, the vehicle may
start to move while a wheel is being changed.
• Never use the folding chocks if they are damaged or if they
have not been assembled correctly.
& WARNING
Improper use of the vehicle jack can cause serious personal inju­
ries.
• Never use the jack supplied with your Audi on another vehicle,
particularly on a heavier one. The jack is only suitable for use on
the vehicle it came with.
• Using a bumper jack to raise the vehicle will damage the
bumper system. The jack may slip, causing injury.
• Never support your vehicle on cinder blocks, bricks or other
objects . These may not be able to support the load and could cause
injury when they fail.
• Never start or run the engine while the vehicle is supported by
the jack.
• If you must work under the vehicle, always use safety stands
specifically designed for this purpose.
• Always make sure the inflatable spare tire and even a flat tire
are secured in place and not loose, otherwise they could fly
forward, causing personal injury to passengers in the vehicle in an
accident or sudden maneuver. •

& WARNING
Batterie s contain electricity, acid, and gas . Any of these can cause
very serious or fatal injury . Follow the inst ructions below for safe
handling of your vehicle 's battery .
• Always shield your eyes and avoid leaning over the battery
whenever possible.
• A discharged battery can freeze at temperatures just below
32 °F (0 °C). Before connecting a jumper cable, you must thaw the
frozen battery completely , otherwise it could explode.
• Do not allow battery acid to contact eyes or skin . Flush any
contacted area with water immediately .
• Improper use of a booster battery to start a vehicle may cause
an explosion.
• Vehicle batteries generate e xplos ive gases. Keep spa rks, flame
and lighted cigarettes away from batteries.
• Do not try to jump start any vehicle with a low acid level in the
battery.
• The voltage of the booster battery must also h ave a 12 -Volt
rating. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery. Use of batter ies of
different voltage or sub stantially different "Ah " rating may cau se
an explosion and personal injury.
• Never charge a frozen battery . Ga s trapped in the ice may cause
an e xplosion.
• Never charge or use a battery that has been frozen. The battery
case may have be weakened.
• Use of batteries of different voltage or substantially different
