2015 AUDI RS5 CABRIOLET fuel cap

196 Checking and filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
- Keep children away from the engine com ­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­ partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park). -
Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~& .

Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manu­
facturer for a tire of a designat­
ed size that has not been driven
for more than a couple of miles (kilometers) at low speeds in
the three hour period before
the tire pressure is measured or
adjusted.
Curb weight
means the weight of a motor
vehicle with standard equip­
ment including the maximum
capacity of fuel, oil, and cool­
ant, air conditioning and addi­
tional weight of optional equip­
ment.
Tires and wheels 213
Extra load tire
means a tire design to operate
at higher loads and at higher inflation pressures than the
corresponding standard tire. Extra load tires may be identi­
fied as "XL", "xl", "EXTRA
LOAD", or "RF" on the sidewall.

224 Tires and wheels
are located on a sticker on
the driver's side B-pillar.
-Only when all tires on the vehicle are filled to the cor­rect pressure, the tire pres­
sure monitoring system*
can work correctly.
-The use of incorrect tire pressure values can lead to
accidents or other damage.
Therefore it is essential that
the driver observe the speci­
fied tire pressure values for
the tires and the correct pressures for the function of
the tire pressure monitoring
system*.
-Always inflate tires to the
recommended and correct
tire pressure before driving
off.
-Driving with underinflated
tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­ loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too
low or too high, the tires will wear prematurely and
the vehicle will not handle
well.
-If the tire is not flat and you
do not have to change a
wheel immediately, drive at
reduced speed to the near­
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem
caps on all wheels are secure­ ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi­
cle and any tire can carry. Ave­
hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can not only lead to loss of vehicle
control, but can also damage .,.

important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your
passengers also depends on
making sure that load limits are not exceeded. Vehicle load in­
cludes everybody and every­
thing in and on the vehicle.
These load limits are technical­ ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the
weight of the basic vehicle, all
factory installed accessories, a
full tank of fuel, oil, coolant and other fluids plus maximum
load. The maximum load in­
cludes the number of passen­
gers that the vehicle is intend­
ed to carry ("seating capacity")
with an assumed weight of 150 lbs . (68 kg) for each pas­
senger at a designated seating
position and the total weight of
any luggage in the vehicle. If
you tow a trailer, the weight of
the trailer hitch and the tongue
weight of the loaded trailer
Tires and wheels 225
must be included as part of the
vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of
the vehicle's two axles.
The Gross Vehicle Weight Rat­ ing and the Gross Axle Weight
Rating are listed on the safety
compliance sticker label locat­
ed on the driver's side 8-pillar.
Your Audi has 4 seating posi­
tions, 2 in the front and 2 in the rear for total seating capacity
of 4. Each seating position has
a seat belt¢ page 123, Safety
belts.
The fact that there is an upper limit to your vehicle's Gross Ve­
hicle Weight Rating means that
the total weight of whatever is being carried in the vehicle (in­
cluding the weight of a trailer hitch and the tongue weight of
the loaded trailer) is limited.
The more passengers in the ve­ hicle or passengers who are
heavier than the standard
weights assumed mean that less weight can be carried as
luggage.

Your vehicle is equipped with all whee l drive,
this will improve traction during winter driv­ ing, even with the standard tires. However, we
strongly recommend that you a lways equip a ll
four wheels on your veh icle w ith correctly fit­
ted wi nte r tires or all -season tires, when w in ­
ter road conditions are expected. This also im­
p roves the vehicle 's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow .
W inter tire s (snow t ires) must always be fitted
on all four wheels.
Ask your authorized Audi dea ler o r qualified
workshop for permitted
w inter t ire sizes. Use
only radia l winter tires .
Winte r ti res lose thei r effectiveness when the
tread is worn down to a depth of
0 .15 7 inch
(4 mm) .
On ly drive with winter tires under winter con­
d itions. Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is above
45 °F (7 °().
If yo u have a flat tire, see notes on repla ce ­
ment whee l¢ page 230 .
Pl ease always remembe r th at w inte r ti res may
have a lower speed rating tha n the t ires origi­
n all y ins talled on your veh icle at the t ime i t
was manufactured . Please see ¢ page 232,
Speed rating (letter code) for a Listing of the
speed rat ing letter codes and the maximum
speed at wh ich the t ires can be driven .
The speed rating letter code( ¢ page
215) is
on the side wall of the tire ¢ page 230.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed befo re driving off . Never drive faster
than the speed permitted for your specific
w inte r tir es . This will cause damage to the
ti res leading to an ac cident and se rious
pe rsonal i njury to you and yo ur p assen­
gers .
Tire s an d wheel s 237
A WARNING
Driving faster than the maximum speed
for which the winter tires on your ve hicle
were designed can cause t ire fail ure in­
cluding a blowout and sudden deflation,
l oss of cont ro l, crashes and ser ious per­
sona l injuries. Have wo rn or damaged ti res
replaced immedia tely.
- Wi nte r tires h ave maxim um speed ra ting
that may be lower than yo ur vehicle 's
maxim um speed.
- Never d rive fas ter than the speed for
whi ch the w inter or othe r ti res installed
on yo ur vehicle are rated.
A WARNING
=
A lways ad just yo ur driving to t he roa d and
traffic conditions. Never let the good ac­
celeration o f the winter tires and a ll wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all wheel drive vehicle handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions.
@ For the sake of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
Snow cha ins may be fitted only to the fro nt
whee ls, and on ly to certain tire sizes . Ask your
autho rized Aud i dea le r o n whi ch tire sizes
snow chains can be used.
The snow chains must have low-p rofile links
and must not be th icker than
0 .41 inch
(10 .5 mm) , in cl ud ing t he lo ck.
Remove wheel center covers and trim discs
before putt ing snow cha ins on your veh icle
