2014 AUDI A5 CABRIOLET wheel bolt torque

driving a few yards and correct if neces­
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this norma lly also applies to
veh icles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit ­
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model<=>
page 266.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop­
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 239
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) w ith a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i­
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k­
shop .
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
tions . Ask your authorized Aud i dealer for
more details .
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s­
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 228 , Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.

use a st urdy board under the jack.
- Always store the vehicle tool kit, the
jack* and the repla ced ti re in the l uggage
compartment

(D Note
If you are chang ing the wheel on a steep
incline, use a rock or similar object to
block the opposite wheel to prevent the
ve hicl e from mov ing.

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction.
Using a sp are t ire w ith a tread p attern
int ended fo r use in a specific dir ection
When us ing a spare tire w ith a tread pattern
in tended for use in a specific direction, please
note the following:
- The direction of rotation is marked by an
a r­
ro w o n th e side o f th e tire .
-If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the ti re will not be able to
achieve its optimum performance character­
i st ics with rega rd to aquaplaning, noise and
wear.
- We recommend that you pay particular at­
tent ion to this fact du ring wet weathe r and
that you adjust your speed to match road conditions.
- Replace the fla t tire w ith a new one and
have it installed on your veh icle as soon as
possib le to restore the handling advantages
of a unid irectiona l tire .
Notes on wheel changing

nents of the tire pressure monitoring sys­
tem* wi ll no longer work properly and the
sensor for the tire pressure monitoring
system* will have to be replaced by quali­
