2011 AUDI A5 CABRIOLET fuel consumption

Driving and environment
The amount of oil used is related to engine load and speed.
It is normal for the oil consumption of a new engine to reach its
lowest value after a certain mileage has been driven.
You must drive your vehicle about 3,000 mi les (S,000 kilometers)
before you can properly assess oil consumption.
Th is also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as improper use of the vehicle w ill
impair the function of the emission control system and could lead to
damage.
• Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not a lter or remove any device, such as heat shields, switches,
ignition wires, valves, which are designed to protect your vehicle's Emission Contro l System and other important vehicle components .•
Fewer short trips
Fuel consumption will always be relatively high on short
trips .
-Try to avoid driving short distances with a cold engine.
The engine and catalytic converter have to reach their optimal oper·
ating 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 m iles 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 mi les (4 km), the engine is at its proper operat ing temperature and fuel economy has reached a normal
level. So you can see that you
should avoid short trips whenever possible .
The
outside temperature is also crit ical in this regard . Your car
consumes more fue l in the winter than in the summer. •

Changing the engine oil
The engine oil and oil filter must be changed according to the mileage
(kilometers) and time intervals specified in your vehicle's Warranty
&
Maintenance booklet. Do not exceed these intervals -harmful
deposits from old engine oil can reduce engine performance and can
lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor .
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay below freezing point for long periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not a
reason to change the oil more often than recommended.
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW
502 00 . Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Service or Repair Orders that all scheduled maintenance
was performed in a timely manner. •
Safety first
Engine oil consumption
The engine in your vehicle depends on an adequate
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 internal 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 250) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil consumption 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 factors are the amount of oil dilution from water
condensation or fuel residue and the oxidation level of the oil. As any
engine is subject to wear as mileage builds up, the oil consumption
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 established or specified. There is no alternative
to regular and frequent checking of the oil level, see
Note.
If the yellow engine oil level warning symbol in the instrument
cluster _ lights up, you should check the oil level as soon as possible
~ page 284. Top off the oil at your earliest convenience~ page 284.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on page
280.

Driv ing with an insufficient o il level is likely to cause severe damage
to the engine .
[ i J Tips
• The oil pressure wa rning display 9:!::r. is not an ind icator of the oil
level. Do not rely on it. Instead, check the oil level
in your engine at
r egula r inte rvals , prefe rably ea ch time you refuel , and always
before going on a long trip.
• If you have the impression your engine consumes excessive
amounts of o il, we recommend th at yo u consult an autho riz ed Aud i
dealer to have the cause of your concern properly diagnosed . Keep in
m ind that the accurate measu rement of oil consumption re quires
great care and may take some t ime. An authorized Audi dealer has
instructions about how to meas ure oil consumption accu rately .•
Checking the engine oil level
Fig. 2 21 MMI D isplay :
Oil le vel ind icat or
Read oil level
-Park your vehicle on a level sur face.
- S hut the engine off when it is warm. -
Switc h only th e ignition back on .
- Wa it appro ximately two minutes.
- Select: Function button
[CAR ]> Oil level.
- Check the oi l level in the display=> fig. 2 2 1. Add e ngi ne oil
if t he ba r of the oil level ind icator is near "min"
=>
page 284 .
The oil leve l needs to be c hec ked at regular intervals. The bes t times
to do this are whe neve r you refuel and p rior to long tr ips.
Depending on the way the vehicle is driven and the operating condi­
ti ons, oi l cons ump tion can be u p to 1/2 q uart per 600 m iles (0.5 l iter
per 1,000 km). Consumpt ion may be higher with in the first 3,000
m iles (5,0 00 km).

Tires and vehicle load limits
There are limits to the amo unt of load or weig ht that any vehicle and
any t ire ca n carry. A veh icle th at is overlo ade d w ill n ot handle well and
is more difficult to stop . Overload ing can not on ly lead to loss of
vehicle co ntro l, bu t can also d amage important pa rts of the vehi cle
and can lead to sudden t ire failure, including a b lowo ut and sudden
deflation that can ca use the vehicle to c rash.
Yo ur safety and t hat of your passengers also depends o n mak ing s ure
that load limits are not e xceeded. Vehicle load incl udes eve rybody
and everyth ing in and on the ve hicle. These load limits are tech nically
refer red to as the veh icle's
Gross Vehicle We ight Rating ("GVWR").
T he "GVWR" includes t he weight of the basic vehi cle, all factory
installed accessories, a fu ll tank of fue l, o il, coo la nt and other fluids
plus maxim um load . The maxim um load includes the number of
passenge rs that the vehi cle is intended to car ry ("seating capacity ")
w ith an ass umed we ight of 150 lbs (68 kg) for each pa ssenger at a
designat ed seating position and the tota l w eight of any l uggage in
the vehicle. If you tow a trai le r, the weight o f the t railer hitch and the tongue weight of the
loaded tra ile r must be included as part of the
veh icle lo ad .
T he
Gross Axle Weight Rating ("GAWR ") is the max imum load t hat
can be a pplied at each of the ve hicle's two axles .
Th e Gross Vehicle Weight Rat ing and the Gro ss Axle Weight Ra ting
are listed on the safety compliance s ticker label located on the
dr iver 's s ide B-pillar. Audi h as 4 seat ing pos it ions, 2 in t he fro nt and
2 in the rear for total seating capacity of 4 . Each seating pos it io n has
a seat belt =>
page 189, "Safety belts" .
Th e fa ct t hat there is an upper lim it to your veh icle 's Gross Vehicle
We ight Rating means that the total weight of whatever is being
c arrie d in t he ve hicle (incl uding t he weight o f a trail er hi tch and the
tongue weig ht of the loaded tra iler) is limited . The more passengers
in the veh icle or p assenge rs who are he avier than the st anda rd
we ights assumed mean that less we ight can be carried as luggage.

& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase 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 di stan ce.
• Tires on a vehicle that has been o verloaded can fail suddenly ,
including a blowout and sudden deflation, causing loss of control
and a crash .
• Always make sure that the total load being transported -
