brake AUDI RS5 COUPE 2015 Workshop Manual

The Gross Axle W eight R ating
("GAWR") is t he maximum load
that can be applied at each of the
vehicle's two axles .
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carr ied in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen ­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage .
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
¢ page 206,
fig .171 .
A WARNIN G
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury , and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in-
Wheels
crease the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance .
- Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash .
- Always make sure that the to­
ta l load being transported -
including the weight of a trail ­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the tota l weight of the pas­
sengers and luggage or other
things that you plan to transpor t
so that you can make sure that
your vehicle will not be overload- ed.

"'Lay the valve insert on a clean surface.
"' Remove the sealing plug from the filling hose
and connect the hose to the tire valve .
"' Hold the bottle w ith the bottom facing upward
and empty the ent ire contents into the tire .
"'T hen pull out the hose and screw the valve in­
sert t ight ly back into the tire va lve.
Inflating a ti re
"' Screw the filling hose for the electric air pump
onto the tire valve and insert the connector into
the cigarette lighter .
"' Inflate the tire between 2.0 and 2.5 ba r and
read the pressure from the ga uge .
"' If this tire pressu re is not reached, drive your
vehicle approximate ly 10 meters forward or
backward so that the sea lant can be redistribut­
ed inside the tire. If at this time the required air
pressure st ill cannot be reached, the tire is too
badly damaged and cannot be repa ired with the
ti re sealant.
F in al ch eck
"' After driving for about 10 minutes, stop and
check the tire press ure.
"' If tire pressure is less than 1.3 bar, the tire is
too severely damaged . Do not cont inue to
drive. Seek professional assistance .
A WARNING
- Turn on the eme rgency flashers and set up
the emergen cy tr iangle if you have flat tire
wh ile in moving traffic. Th is is for yo ur pro­
tection and the for the safety o f other driv­
ers.
- Have all passengers leave the vehi cle and
stay away from the danger zone (for exam ­
ple, behind a guard rail).
- Read and fo llow the manufacturer's safety
precautions on the compressor and in the
instructions on the bottle of sealant!
- If a t ire pressure of 2.0 bar cannot reached
after inflating for six minutes, then the tire is too severe ly damaged . Do not contin ue
dr iv ing !

-Obtain qua lified help i f it is not possible to
perform the repair w ith the t ire sea lant.
- If the tire pressure is less than 1 .3 bar after
10 minutes of driving, then the the t ire is
too severe ly damaged. Do not continue driv­
ing. Seek professional assistance.
(D Note
Partic ular care is necessary if you are mak ing
a tire repa ir on a steep incl ine.
(D Tips
- Do not operate the electric air pump for
more than 6 minutes witho ut stopp ing, oth­
erwise it can overheat. When the air pump
has cooled down, you can continue to use it.
- If sea lant has spilled out, let it dry and then
you can remove it by peeling it away like a
foil.
- Remember to obtain a new bott le of sealant
from your authorized Audi dealer after re­ pairing a tire. After this, the functionality of
the tire repair set is restored .
- Obey all laws.

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases , other parts of the car must first be re­
moved before you are ab le to get to the bulb .
This applies especially to the light bulbs in the
front of you r ca r which you can only reach
through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, parts must be
Fuses and bulbs
correct ly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high electr ical voltage, have the bulbs
replaced by a qualified technician . Head lights
with Xenon light are identified by the high volt­
age sticker.
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light) * life -threatening injuries
can result from improper handling of the
high -vo ltage portions of such lamps!
-On ly your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts . If
you are uncertain about what to do, have
the wor k performed by an autho rized Audi
dealer or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work .
(D Tips
-If you st ill prefer to replace the light bulbs
yourself, be aware that the eng ine compart­
ment is a hazardous area to work
inq page 187 q &..
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb.
