2015 AUDI A4 ECU

268 What do I do now?
-Check the tire pressure on the spare imme­
diately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as possible by your authorized Audi dealer or
qualified workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lbs. (120 Nm).
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing
a tire, they should be replaced before you
check the tightening torque.
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover.
Until then, drive with extra care and at re­
duced speeds.
A WARNING
- If you are going to equip your vehicle
with tires or rims which differ from those
which were factory installed, then be
sure to read the information ~
page 248,
New tires and replacing tires and
wheels.
- Always make sure the damaged wheel or
even a flat tire and the jack and tool kit
are properly secured in the luggage com­
partment and are not loose in the pas­
senger compartment.
- In an accident or sudden maneuver they
could fly forward, injuring anyone in the
vehicle.
- Always store damaged wheel, jack and
tools securely in the luggage compart­
ment. Otherwise, in an accident or sud­
den maneuver they could fly forward,
causing injury to passengers in the vehi­
cle.
@ Note
Do not use commercially available tire
sealants. Otherwise, the electrical compo­
nents of the tire pressure monitoring sys­
tem* will no longer work properly and the
sensor for the tire pressure monitoring system* will
have to be replaced by quali­
fied workshop.

28 4 Con sum er Inf ormation
comp lexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, s afety an d e nvir onm ent al con­
cerns place very strict limits on the nature of repairs and adjustments to engine and trans ­
miss ion pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure proper
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­ ranty. Therefo re , proof of servici ng in accord­
ance w it h the ma intenance sched ule may be a
condition for upholding a possible warranty
claim made within the warran ty period.
Above all, operational safety can be adve rsely
affected, c reating unnecessary risks for you
and your passengers.
If in doubt about any serv icing, have it done
by your author ized Audi dealer or any properly
equ ipped and qu alified workshop. We strong­
l y urge you to give your authorized Audi dea ler
the opportunity to perform all scheduled maintenance and necessary repairs . Your deal­
er has the facilities, or iginal parts and trained
specialists to keep your veh icle running prop­
erly.
Performing lim it e d m aint en anc e y ourself
The following pages describe a limited num­
ber of procedures which can be performed on
you r vehicle with ordinary tools, should the
need arise and trained personnel be unavaila­
ble. Before performing any of these proce­
dures, always thoroughly read all of the app li­
cable text and ca refully follow the instruc­
tions given. Always rigorously obse rve the
WARNINGS p rovided .
Before you ch eck anything in th e engine
compartm ent, alw ays read an d hee d all WARNINGS
¢ & a
nd ¢ & in Working in the
engine comportment on page 212 .
A WARNING
--Serious personal in jury may occur as a re-
sult of improperly performed mainte­ nance, adjustments or repa irs.
- Always be extremely careful when work­
ing on the vehicle. Always follow com­
monly accepted safety pract ices and gen­
eral common sense. Never r isk personal
in jur y.
- Do not attempt any of the maintenance,
checks or repairs descr ibed o n the fol­
lowing pages if you are not fu lly fam iliar
with these or other procedures with re­ spect to the ve hicl e, or are uncerta in how
to proceed .
- Do not do any work withou t the proper
too ls and equipment . Have the necessary
work done by your authorized A udi deal ­
er or any properly equipped and q ualified
workshop.
- The engine compar tment o f any motor
vehicle is a potentially hazardous area. Never reach into the area around or
touch the rad iator fan. It is temperature
control led and can sw itch on suddenly -
even when the engine is off and the igni­
tion key has been removed. The rad iator
fan switches on automatically when the coo lant reaches a certain tempera ture
and will cont inue to run until the coo lant
temperature drops .
- Always remove the ign ition key befo re
a nyone gets under the veh icle.
- Always suppor t your veh icle with safety
s tands if it is necessary to work under­
neath the vehicle. The jack s upplied with
the vehicle is not adequate for this pur ­
pose and co uld co llapse causing serio us
personal injury.
- If you must work unde rneath the vehicle
with the wheels on the ground, a lways
make sure the vehicle is on leve l ground,
that the wheels are always securely blocked and that the engine cannot be
started.
