Driving and environment
(I] Tip s
The consumption estimates as pub lished by ENV IRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating .
-Avo id unnecessary accelerating and braking.
Vehicles use the most fue l when they a re accele rating. If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example when you see that the next traffic l ight is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed .
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approx imately three
qua rters of top speed, fuel consumption will be reduced by one half.
Never drive faster than the posted speed limit and weather condi­
tions permit.
a Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
-
Shut the engine off when yo u are not driving the vehicle.
- Do not warm up the vehic le by letting the eng ine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting for
trains to pass at rai lroad crossings, o r at traffic lights that have long
wa its on red . Turn ing the eng ine off for just 30-40 seconds saves
more fuel than is burned starting the engine again.
It takes a long t ime for the engine to warm up fully when it is running
at idle. Howeve r, wear and noxious emissions are espec ially high
when the eng ine is wa rm ing up. So you sho uld d rive away as soon as
you start the engine and avoid running at hig h rpms while the eng ine
is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which cou ld result in
overheat ing o r othe r damage to the vehicle or other p roperty. •
Regular maintenanc_e ____________ _
A badly tuned engine unnecessarily wastes a lot of fuel .
- Have your vehicle serviced at regular intervals .
By having yo ur vehicle regularly se rviced by an Audi dealer helps to
ensure that it runs properly and economically . T he condition of your
vehicle not only a ffects its safety and ability to ho ld its va lue, it a lso
affects
fu el con sumption .
Check your o il e ach tim e you fill you r tank.

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 miles (5,000 kilometers)
before you can properly assess oil consumption.
This 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 cou ld lead to
damage.
• Do not alter or remove any component of the Emission Control
System un less approved by the manufacturer.
• Do not a lter or remove any device, such as heat shie lds, 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 eng ine and catalytic converter have to reach thei r optima l oper­
ating temperature
to reduce fuel consumption and noxio us em is­
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 miles (4 km), the engine is at its proper operating temperature
Controls and equip­
ment Safety first Vehicle operation
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 cr it ical in th is regard . Your car
consumes more fuel in the winter than in the summer. •

the formation of harmful deposits, sometimes ca lled "sludge," that
over time can lead to expensive re pairs.
At the time of pr int ing, engine o ils available in the U .S . and Canada
that meet the exacting s pecifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So a lways
be s ure that you use an approved o il.
To help prevent the format ion of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oi l stand ard VW 502 00
Oil container labels may carry the specification singly or in comb ina­
tion with other designations and o il quality standards.
Vi sco sit y
Engine oils are graded according to their viscosity . The proper
viscos ity grade oil for your eng ine depends on climactic or seasonal
conditions where you drive. You can use oi l with a v iscosity grade of
SAE SW40 across all tempera ture ranges for norma l driving cond i­
tions.
However, if engine o il viscosity grade SAE SW40 is not avai lable, you
can a lso use viscos ity grade SAE SW-30 or SAE OW-40 as long as it
meets Audi oil quality standard VW 502 00 specifications .
Be cause eng ine oil that meets the A udi oil standard may not be avail­
able everywhere when you need it, we strongly recommend that you
always carry w ith you an extra quart (liter) o f oi l that expressly
conforms to the VW 502 00 specif ication, in case you have to top off
the oi l while on the road.
On ly if the level of the o il is at or be low the min imum mark on the oil
dipstick - and no oil that expressly conforms to Audi oi l standard
VW 502 00 spec ificat ions is ava ilable - may you top off with a high
quality engine oil, preferably synthetic-based, that meets ACEA A3,
ACEA AS or ACEA BS or AP I SL spec ifications, but even then, on ly in
viscos ity grades SAE SW-40, SAE SW-30, or SAE OW-40. However,
dur ing t he entire time between oil change intervals, neve r top off w
ith more tha n a total of 0 .5 qt/liter eng ine o il that does not
con form to Audi o il specification VW 502 00.
For more information abo ut eng ine oil that has been approved for
your vehicle, p lease contact either your authorized Audi dealer or
Audi Customer Relat ions at 1 (800) 822-2834 or v isit our web site at
www.audiusa.com or www .audicanada.ca. Here you will also find a
cur rent list of oils (manufacture rs, brand names e tc.) t hat co nform to
Audi oil standard VW 502 00.
Chan ging the e ngine oil
T he eng ine oil and oil fi lter must be changed according to the mileage
(kilometers) and time interva ls specified in your vehicle's Warranty
&
Maintenan ce boo klet. Do no t exceed these interva ls - harmful
deposits from old eng ine oil can reduce engine performance and can
lead to expensive engine repairs.
Chang ing t he oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually d uring
normal veh icle use. If you are not sure when you have your o il
changed, ask your authorized A udi Service Advisor.
Under some circumsta nces the engine oil should even be changed
more frequently. Change oil more often if you drive most ly short
dis tances, ope rate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
a tures stay below freezi ng point for long periods .
Detergent add itives in the oil will make fres h oil look dark after the
engine has been running for a short t ime . This is normal and is not a
reaso n to cha nge the oil mo re often than recommended.
Damage or malfunctions due to lack of maintenance
It is essentia l that you change your o il at the recommended intervals
using only engine o il that comp lies w it h Aud i oil standard
VW 502 00 . Your Limited New Vehicle Warranty does not cover
damage or ma lfunctions due to fa ilure to follow recommended main­
tenance and use requirements as set forth in the Aud i Owner's
Ma nual and W arra nty
& M ai ntenance book let. Your deale r will have
to deny warranty coverage unless you present to the dealer proof in ._

eng ine is s ubject to wear as mileage builds up, the oil consumption
may increase over time until replacemen t of wo rn components may
