::r ' engaged, for example when you notice that t he
next traffic light is red . This produces an engine
b raking effect, wh ich he lps to protect the brakes
and tires and reduces the emissions and f uel con­
sumpt ion to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficientl y
Upshifting earlier is an effective way to save fue l.
Staying in a gear too long uses fue l unnecessari­
ly .
Press down on the acce lerator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You sho uld rare ly t rave l at the maxim um vehicle
speed. High speeds cause a d isp roportiona tely
hi gh increase in fuel consump tion, emissions and
traffic noise . Driving more slowly saves f uel.
Reduce idling time
The Start/Stop system* he lps to reduce the id ling
time automatically. In vehicles wi thout the Sta rt/
Stop system*, it is efficient to switch the engine
off when stopped at ra ilroad crossings and long
red lights . Stopping the engine for
30 -40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
I t takes a very long time in idle to wa rm the en­
gine up to operating temperature . Wear and
emissions are especially high in the warm -up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while do ing th is .
Have maintenance perf ormed regularly
By having maintenance performed regu larly on
your ve hicle, you can he lp to reduce fuel con ­
sumpt ion before you even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l­
so impacts fuel consumption . A poorly main­
tained engine can lead to fuel consumpt ion that
i s
1 0% hi gher tha n normal.
Driving
Avoid short trips
T he eng ine and exh aust cleaning system mus t
r each their optima l operat ing temperatu re to ef ­
fectively reduce consumption and emissions.
A cold engine uses a d isp roportionately high
amoun t of fue l. The engine re ac h es operat ing
temperat ure and cons umption norma lizes on ly
after approximate ly 2.5 mi les (4 km) .
Check the tire pressure
To save fuel, ma ke sure the t ires are always i n­
flated to t he correct pressure~
page 340. The
fuel consumpt io n can increase by
5% if the pres ­
s u re is on ly
0 .5 bar too low. Due to the increased
rolling resistance, low tire pressures wi ll also
l ead to greater tire wear and will affect driving
behavior.
Do not drive on winter tires year -round, as this
will consume up to
10% more fuel.
Eliminate unnecessary weight
S ince eve ry po und of ext ra weight increases f uel
co nsump tion , a quick inspect io n of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rac k sho uld be re­
moved to decrease the w ind resis tance of the ve ­
hicle . This will save you approximately
12% fu el
at speeds from
62 -75 mph (100 -120 km/h) .
Save energy
The eng ine d rives the generator, which generates
electric ity; the fuel consumpt io n also increases
wi th the dema nd for e lec tric ity . T he refore, sw itch
electrical eq uipment off when you no longer
need it . Examples of eq uipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle or other proper ­
ty .

the cruise control from braking. This is be ­
cause pressing the accelerator pedal over­
rides the cruise contro l system .
- If a brake system ma lfunction such as over­
heating occurs when the cruise control sys­
tem is sw itched on, the braking function in
the system may be switched off . The rest of
the cruise control system functions remain act ive as long as
the @;\l)~ij (USA models) /

Gasoline additives
A ma jor concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline yo u use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. A l­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website
(www .toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
g ine of peak performance.
