engine overheat AUDI R8 SPYDER 2015 Owners Manual

Instrum ent s a nd w arn ing /indi cator lights
-Never open the engine compartment lid if
you see or hear steam, or if you see engine coolant dripping from the engine compart­
ment. You could burn yourself. Let the en­
gine cool off first until you can no longer see
or hear steam or coo lant escaping .
CD Note
- Mount ing additional lights or accessories in
front of the a ir inlets reduces the cooling ef­
fect of the rad iator. At h igh outside temper­
atures or high engine load, the engine could
ove rheat.
- The front spo ile r has been designed to prop­
erly distribute the cooling air when the veh i­
cle is mov ing. If the spo iler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author­
ized Audi dealer for assistance.
Fuel gauge
The fuel gauge works only when the ignition is
on. When the needle reaches the red area, the
warning light in the instrument cluster will illu­
minate

CD Note
Never run the tank completely dry! An irregu­
lar supply of fuel can cause engine m isfiring
and fuel could enter into the exhaust system .
The catalytic converter cou ld then overheat
and be damaged.

Speedometer with odometer
The speedometer shows you the vehicle speed,
and the odometer shows you how many miles
(kilometers) you have driven.
Fig. 5 Speedo meter close-up: odometer disp lay
The distance driven is shown in mi les (USA mod­
els) or in kilometers (Canada models).
Lower odomet er
The lower odometer shows the tota l number of
miles ( kilometers) driven .
Upper odometer (trip odometer )
The upper odometer shows the total number of miles (k ilometers) driven since you last reset the
odome ter back to zero. You can use this odome­
te r when you want to keep track of how many
miles (k ilomete rs) you have driven for a sing le
trip or errand. The last digit ind icates 1/10 of a
mile (100 meters). You can set the trip odometer
back to zero by pressing the reset button

A WARNING
-
- Never leave your vehicle with the engine
ru nning while in gear. If you must leave yo ur
vehicle with the engine r unning, set the
parking brake firmly and engage neutral
N .
- With the engine r unning and a gear engag­
ed, you have to ho ld the vehicle with the
foot brake .
- Do not accelerate when you sh ift gears with
the vehicle stationary and the engine run­ ning.
- Before driving down a steep slope, reduce
your speed and sh ift into a lower gear with S
tronic.
- Do not ride the bra kes or press the bra ke
pedal too often or too long. Constant brak­
ing causes the brakes to overheat and sub­
stantially reduces brak ing performance, in­
creases braking d istance or causes comp lete
fa ilu re of the brake system. ..,.

Anti-loc k br aking sy stem (ABS )
ABS prevents the wheels from locking up when
brak ing . T he vehicle can st ill be stee red even dur ­
ing hard braking. App ly steady pressure to the
brake peda l. Do not pump the peda l. A pulsing in
the brake pedal indicates that the system is help­
ing you to brake the vehicle.
Brake assist sy ste m
The brake assist system can decrease braking dis ­
tance. It increases braking power when the dr iver
presses the brake pedal quick ly in emergency sit­
uations. You must press and ho ld the brake pedal
until the situation is over.
Anti -slip regulation (ASR )
ASR reduces engine power when the drive whee ls
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acceler ­
ate and dr ive up h ills.
Electronic diff erential lock (EDL )
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive wheel or wheels if the vehicle is equipped w ith all-whee l
drive*. This function is available up to about 60
mph (100 km/h) .
I n extreme cases , EDL automatically switches off
to help keep the brake on the braked wheel from
overheating . EDL wi ll switch on again automati­
cally when conditions have returned to normal.
A WARNING
- ESC, ABS, ASR and EDL cannot overcome the
laws of phys ics. Th is is especially important
on slippery or wet roads. If the syst ems be­
gin act ing to stab ilize your vehicle, you
sho uld immediately cha nge your speed to
match the roa d and traffic con ditions. Do
not let the increased safety provided by
these systems tempt you to take risks . Do­
ing so wi ll increase the risk of a loss of vehi­
cle contro l, collis ion and serio us personal in­
juries .
- Always adapt your speed to road, traffic and
weather cond it ions. The risk of losing con­
tro l of the veh icle increases when driving
Int ellig ent t echnolo gy
too fast, especially through curves and on
slippery or wet roads, and when dr iving too
close to vehicles up ahead. ESC, ABS, the
brake assist system, EDL and ASR cannot
prevent coll is ions .
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance sys tems that cannot always help to reduce
the risk of loss of veh icle control.
(D Tips
- ABS and ASR only wo rk correctly when all
four wheels are eq uipped with ident ical
tire s. Different tire s izes can lead to a reduc­
t ion i n engine power.
- Yo u may hear noises when the systems de­
sc ribed a re wo rking.
- If the ind icator light GJ or II (USA mod­
els) ;tiJ (Canada models) appea rs, there
may be a malfunction~

This can cause a temporary reduction in braking
force compared to dry brakes. You can compen­
sate for this by pressing the brake pedal harder.
Cor ro sion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to fo rm on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes.
If the b rakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few times from a moderately high speed
c:> &. .
Faults in the brake sy stem
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have fai led
c:> .&, .
Low brak e flu id le vel
Malfunct ions can occur in the brake system if the
brake fluid level is too low. The brake flu id leve l is
monitored e lectronically.
Br ake power assis t un it
T he brake power assist unit increases the pres­
sure that you generate with the brake pedal.
It
works only when the eng ine is running .
Brak e lining wear sta tu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 203 .
.8, WARNING
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the init ial 250 mi les ( 400 km) of normal city
driving. The break -in period can be consider­
ably longer for vehicles with ceramic brake
rotors *. You can compensate for this by
pressing the brake pedal more firmly. This
also applies later when new pads are instal­
led .
- You should perform brak ing maneuvers for
the purpose of clean ing the brake system
Int elli ge nt te chn olo gy
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an accident!
- Before descending a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could cause the bra kes to get
hot and dimin ish braking effic iency .
- Do not "ride the brakes" by rest ing your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premat ure wear and increased stop­
ping distance.
- Under certain cl imatic and operat ing condi ­
tions such as passing thro ugh water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, lin ings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can also affect braking efficiency .
Clean off accum ulated salt coating from
b rake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be su re the air flow
to the front brakes is not obstructed . O ther­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem .
- Fai lure of one brake circuit will impai r the
braking capability resu lting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest Aud i dea ler
or qualif ied workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, for ex­
ample when towing your veh icle, or because
the brake booster has somehow been dam­
aged, the brake pedal must be pressed con ­
siderably harder to make up for the lack of booster assistance.

The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
- Do not park or operate the vehicle in areas where the hot exhaust system may come in contact with dry grass, brush, fuel spill or
other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or
heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
([) Note
-Be aware that just one tank filling with lead­
ed
fuel will already seriously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
~page 160.
- Do not drive until the fuel tank becomes
completely empty. The engine could misfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
lytic converter to overheat.
- Do not turn off the ignition while the vehicle
is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requir­
ing its replacement.
- To assure efficient operation of the Emission
Control System:
- Have your vehicle maintained properly and in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
Driving and environment
{® For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline .
Shutting down vehicle
If you would like your vehicle to remain inopera­
tive for a longer period of time , contact an Audi
or other specialized dealer. They can advise you
on necessary precautions e.g. corrosion preven­
tion, maintenance and storage. Pay attention to
additional information concerning the battery.
Refer to~
page 164.
Operation and
maintenance
Fuel economy, environmental impact, and wear
on your engine, brakes and tires largely depend
on three factors:
-your personal driving style
- operating conditions
- technical limitations
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it runs properly and economically. The condition of
your vehicle not only affects its safety and ability
to hold its value, it also affects
fuel consump­
tion.
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile­
age has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly as­
sess oil consumption .
This also applies to fuel consumption and engine output . .,,.

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­
tects the engine from freezing in the winter.
T he coo ling system is sealed and genera lly re­
quires little attention.
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of a mixtu re of
specially conditioned wate r and the manufactur­
er's glycol-basedcoolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­ els; 60% for Canadian models). This mixture both
assures the necessary frost protection and pro­
tects metal components in the engine's cooling
system from corrosio n and scaling. It also ra ises
the boiling point of the coolant .

The expansion tank in your vehicle is equipped
with an electric coolant level sensor
r::!) page 14.
We still recommend you check the coolant level
from time to time .
Coolant lo ss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cooling
system should be inspected immediately by your
author iz ed Audi dealer. It is not enough merely
to add coolant.
In a
s e a led system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheat ing.
A WARNING
- The cooling system is under pressure. Do
not open the cap of the coolant expans ion
tank when the engine is hot. You risk being
sca lded.
-
- The coolant add itive, and therefore the cool­
ant itself, is hazardous to health. Keep the
c oolant additive in the or igina l co ntainer out

It is a poison haz­
ard.
Ch eck ing and fillin g
(D Note
Do not add any type of radiator leak sea lant
to your vehicle's engine coolant . Add ing radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Veh icle Limited Warranty.
