2015 AUDI RS5 CABRIOLET fuel consumption

24 Driver information d isplay
Trip computer
Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 9 Trip computer display: Average fuel mileage
The following information is continuously
eva luated by the trip computer and can be dis­
played sequentially in the instrument cluster
display:
Fuel range
The estimated cruising range in miles (km)
appears in the display. This tells you how far
your ve hicle wi ll be able to travel on the cur­
rent tank of fuel and with the same driving
style. The display changes in increments of
5 miles (10 km).
The cruising range is calcu lated based on the
fuel consumption for the last 18 miles
(30 km).
If you drive conservat ively, the cruis­
ing range will increa se.
Average fuel mileage The average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display. You can use this display to adjust
your driving technique to achieve a desired mileage.
Current fuel mileage
The instantaneous fuel consumption in mi les
per gallon (l/100 km) is shown in this display .
You can use this display to adjust your driving
technique to achieve a desired mileage. Fuel
consumption is recalcu lated at intervals
of 33 yards (30 meters). This disp lay switches
to gallons/hour (liters/hour) when the vehicle is not moving.
Average speed
T he average speed in mph (km/h) s ince you
last reset the memory appears in the display.
Elapsed time
The length of time that you have been driving
s ince you last reset the memory appears in
th is disp lay.
Distance
The distance that has been covered since the
last t ime the memory was cleared appears in
the display.
(0 Tips
- Fuel consumptions (average and cur­ rent), range and speed are displayed in
metric units on Canadian models.
- All stored values will be lost if the vehi­
cle battery is disconnected .
Memories
The trip computer is equipped with two fully
automatic memories.

(D Note
-Be aware that just one tank fi lling with
le ad ed fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
c>page 199.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis ­
fire. Unburned fuel could also get into
the exhaust system and this could cause
the catalyt ic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is moving .
- Do not continue to operate your vehicle
under these condit ions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement.
- To assure efficient operat ion of the Emis­
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and could lead to damage .
@) For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fuel being used.
Using a d ifferent brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Shutting down vehicle
If you would like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Audi or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro ­
sion prevention, maintenance and storage.

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex ­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely depend on three factors:
- your personal d riving style
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTEC TION AGENCY
( E PA) and Transpo rt Canada may not cor re­
spond to your actual consump tion on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con ­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most f uel when they a re ac­
ce lerat ing. If you ant icipate what is going to
happe n next, you will need to brake less and,
th us, acce lerate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.

182 Driving and en vironm ent
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage .
"'Try and keep well below your car 's max imum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
g ine no ise increase d isproportionately at high
speeds. If you dr ive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never dr ive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
"'Shut the engine off when you are not dr iv ing
the vehicle .
"'Do not warm up the veh icle by letting the
engine run at idle .
It makes sense to shut
off the e ngine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings , or at traff ic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
bu rned s tarting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . Howeve r, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
([) Note
Do not leave engine idling unattended af ­
ter starti ng . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over- heating o
r othe r damage to the ve hicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"' Have your ve hicle serviced at reg ular in ter -
vals.
By having your veh icle regu la rly serviced by an
a utho rized Aud i dea le r helps to ensure that it
runs properly and econom ic all y. The cond it ion
of your veh icle not on ly affe cts its safety and
ability to ho ld its va lue, it a lso affects
fuel
con sumption .
Check your oil ea ch time you fill your tank.
The amount of o il used is re lated to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l cons umption and en­
gine output.
(D Note
- Have your vehicle maintained proper ly
and in accordance with the service rec ­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alte r or remove any device, such
a s hea t sh ie lds, swi tches, ig nitio n w ires,
valves, which are designe d to p rotec t
your vehicle's Emission Control System
and other impo rtant vehicle compo­
nents .

Fewer short trips
Fuel consumption will always be relatively
high on short trips.
11-Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effectively .
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 m iles (4 km),
the engine is at its proper operating tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you should avoid
short trips whenever possible.
The
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer.

198 Checking and filling
Using the proper engine oil is important for
the functionality and service life of the en­
gine. Your engine was factory-filled with a
high-quality oil which can usually be used
throughout the entire year.
0 Note
Your Limited New Vehicle Warranty does
not cover damage or malfunctions due to
failure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet.
- Use only a high quality engine oil that ex­
pressly complies with the Audi oil quality
standard specified for your vehicle's en­
gine . Using any other oil can cause seri­
ous engine damage.
- Do not mix any lubricants or other addi­
tives into the engine oil. Doing so can
cause engine damage.
If you need to add oil and there is none
available that meets the Audi oil quality
standard your engine requires, you may
add a total of no more than 0.5 quart/liter
of a high-quality "synthetic"oil that meets
the following specifications.
- Vehicles with gasoline engine: ACEA A3
or API SM with a viscosity grade of
SAE 0W-30, SAE SW-30 or SAE SW-40.
- For more information about engine oil
that has been approved for your vehicle, please contact either your authorized
Audi dealer or Audi Customer Relations
at 1 (800) 822-2834 or visit our web site
at www.audiusa .com or
www .audicanada .ca .
Engine oil consumption
The engine in your vehicle depends on an ade ­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cooling of internal engine components, all in­
ternal combustion engines consume a certain amount of oil. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see
¢ page 179) consume more oil during the
break -in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions . Further fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump­
tion may increase over time until replacement of worn components may become necessary.
With all these variables coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev­ el, see
Note.
If
the yellow engine oil level warning symbol
El in the instrument cluster lights up, you
should check the oil level as soon as possible
¢ page 199. Top off the oil at your earliest
convenience
¢ page 199.
A WARNING
--
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
& in Working in the engine
compartment on page 195.
{(D Note
Driving with an insufficient oil level is like­
ly to cause severe damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­ erably each time you refuel, and always
before going on a long trip. .,.

26 6 Con sum er Inf ormation
-Always make sure the transmission se­
lector lever (automatic transmiss ion) is
in "P" (Park position) and the park brake
is f irmly app lied .
@) For the sake of the environment
-Changing the engine settings wi ll ad­
versely affect em iss ion levels. This is det­
rimental to the environment and increas­
es fuel consumption .
- Always observe env ironmental regula­
tions when dispos ing of old engine oil,
used brake fluid, dirty engine coolant,
spent batteries or worn out tires.
- Undeployed airbag modules and preten­
s ioners might be classified as Perchlo ­
