If you do not drive your vehicle for several days or weeks, e lectrical
consumers are gradually scaled back or switched off. Th is reduces
energy use and ensures the vehicle will be able to start after long
periods of time~
page 194. Some convenience functions such as
opening with the remote control key may not be available. These
convenience functions will be available again once you switch the
ignition on and start the engine. Even when consumers are switched
off, the battery will become deeply discharged by stand-by power
consumers if the vehicle is not driven for several months . Deep
discharging results in a chemica l reaction that destroys the inside of
the battery. The battery must be charged every month to prevent th is

system* will not work.
Winter operation
Cold weather places higher demands on the battery. This results in
reduced starting abi lity. Have the battery checked and recharged if
necessary before the cold weather beg ins.
Avoid unnecessary power consumption, part icularly in city traffic or
when travel ing on ly short distances. Let your author ized Audi dealer
Safety first
check the capacity of the vehicle battery before winter sets in
~ page 241. A well charged battery will not only p revent start ing
problems when the weather is cold, but will also last longer.

& WARNING
• If the tire pressure indicator appears in the instrument cluster
display, one or more of your tires is significantly under-inflated. Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible and check the tires
and their pressures . Inflate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire pressure label=>
page 249.
Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also is likely
to impair the vehicle's handling and stopping ability.
& WARNING (co ntinued )
• The driver is responsible for maintaining the correct tire pres­
sures . You must check the tire pressures regularly .
• Under certain conditions (such as a sporty driving style, winter
conditions or unpaved roads), the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run-flat tires may be used on
your vehicle. Your vehicle registration becomes invalid if you use
these tires when not permitted. Damage to your vehicle or acci­ dents could also result.
