Us ing the ABS sensors, the tire pressure monitoring system compares
t he t ire tread c ircumference and vibrat ion characte rist ics o f the indi
vidual tires. If the pressure decreases in one or more tires, this is indi
cated in the ins trument cl uste r wi th a warning symbol

message=> fig. 246 . The dr iver message in the display goes o ut after
5 seconds . T he driver message can be disp layed again by p ressing the
[ CHECK ] button. If only one t ire is affected , the display will ind icate
its position . The tire press
ure monitoring must be reset via MMI each time the
pressu res are adju sted (e.g. when sw itching between partial and full
load pressure) or after chang ing or replacing a t ire on your veh icle
=>

chocks . To use the chocks, you first have to raise the support plate
=>
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. •
