change wheel AUDI A5 COUPE 2018 Owner's Manual

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-
pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 351, fig. 284.

(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 353
or for a full load
when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

Wheels
check you r tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
also reduces fuel efficiency and t ire tread life,
a nd may affect the veh icle's handling and stop ­
p ing ability .
Please note that the TPMS is not a substit ute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma inta in correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat io n of the TPMS low tire p res­
sure tellta le.
Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion i nd icator to indicate when the sys­
t e m is not operat ing properly. The TPMS ma l­
f u nction indicator is comb ined w ith the low tire
p ress ure tellt ale. Whe n the system dete cts a
malfunct ion, the te lltale will flash for approxi­
mate ly one min ute and then remain continuo usly
i l luminated. This sequence will continue upon
subseq uent veh icle start- ups as long as the ma l­
function ex ists .
When the malf unctio n indicator is ill uminated,
the system may not be able to detect or signa l
low tire pressure as intended . TPMS ma lf u nctions
may occur for a variety of reasons, including the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning prope rly . Always c heck the
TPMS malfunct ion tellta le afte r replacing one o r
mo re t ires o r whee ls on your ve hicle to e nsu re
t hat the repla cement or altern ate t ires and
wheels a llow the TPM S to con tinue to function
p roperly.
If the tire pressure monitoring indicator
appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Using the ABS sensors, the tire pressure mon itor­
ing system compares the tire tread circ umfer­
ence and vibration cha racteristics of the individu­
a l tires. If the pressure changes in one or more
tires, this is ind icated i n the instrument cluste r
360
display with an indicato r light RE and a message .
If only one tire is affected, the location of that
t ir e will be indicated.
The tire press ures mus t be sto red in the Infotain­
ment system again each time the p ress ures

Fig. 293 Sill: positio ning the vehicle jack
• Place the veh icle jack* (vehicle tool kit) on a
firm s urface. Use a flat, stable support if neces­
sary. On a slippery surface such as tile, you
should use a non-slip pad (such as a rubber
mat)¢ &.
• Find the marking on the sill that is closest to
the tire that will be changed
¢fig. 292. Behind
the marking, there is a lifting point on the side
sill for the vehicle jack*.
• Turn the handwheel to raise the vehicle jack*
under the lifting point on the side sill until the
bracket on the jack @ completely covers the
notch on your vehicle.
• Align the vehicle jack* so the bracket @covers
the notch and the base ® is flat on the ground.
The base ® must be directly under the lifting
