wheel bolts AUDI A5 2015 Owner´s Manual

_& WARNING -
-Only use tire/rim combina­tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
- For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
- Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than 6 years old when abso­
lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
Wheels
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 169 Tire profile: Treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
- Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
- Have an authorized Audi dealer
or authorized repair facility
check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can ma ke sure that
your vehicle will not be overload­ ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU­ PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehi cle's pla card
(tire inflation pressure label)
¢ page 215 , fig. 170.
2 . Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3 . Subtract the combined weight
of the driver and passengers
from
"XXX " kilograms or "XXX"
pound s shown on the sticker
¢ page 215 , fig. 170 .
4. The resulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample, if the
" XXX" amount
equals 1400 lbs. and there will
Wheels
be five 1 SO lb s. passenger s in
your vehicle, the amount of available cargo and luggage load capa city is 650 lb s.
(1400-750 (5 X 150) = 650
lb s.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle .
That weight may not safely e x­
c eed the available cargo and
luggage load capa city cal culat­
ed in Step 4 .
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your vehi­
cle. Con sult thi s manual to d e­
termine how this redu ce s the
available cargo and luggage load capacity of your vehicle .
.,.Check the tire sidewall
(¢ page 205 , fig. 168) to deter­
mine the designated load rating
for a specific tire.
Wheel bolts and rims

Wheels
A WARNING
Wheel bolts that are tightened or repaired in­correctly can become loose and result in loss
of vehicle control , which increases the risk of
an accident. For the correct tightening specifi­
cation, refer to
c:> page 22 7, After changing a
wheel.
- Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized repair
facility. Never repair or disassemble rims
yourself, because this increases the risk of an accident.
Winter tires
Winter tires significantly improve the vehicle's handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
.., Use winter tires on all four wheels .
.., Only use winter tires that are approved for your
vehicle.
.., Please note that the maximum permitted
speed may be lower with winter tires
c:> .&,.
Your authorized Audi dealer or authorized re­
pai r facility can inform you about the maximum
permitted speed for your tires .
.., Check the tire pressure after installing wheels
c:> page 215.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1S7 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re ­
gardless of the remaining tread.
A WARNING
-Never drive faster than the maximum per­
mitted speed for your t ires. This could cause
the tires to heat up too much . This increases
the risk of an accident because it can cause
the tire to burst.
220
- Always adapt your driving to the road and
traffic conditions. Drive carefully and reduce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only win­
ter tires w ith the
& symbol may be permit­
ted.
· Snow chains
Snow chains improve traction in the snow .
.., Only install snow chains on the front wheels.
This applies also to vehicles with all wheel drive* .
.., Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer .
.., Note the maximum permitted speed when driv­
ing with snow chains . Do not exceed 30 mph
(SO km/h) .
Snow chains not only improve the
driving in win­
ter road conditions, but also the
braking.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­
ized repair facility to see if you may use snow
chains .
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.S mm) in height, includ­
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow. When roads are free
of snow, snow chains can impair handling and .,.
