Instruments and indicator lights
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed may
be slightly higher than the actua l temperature
outside due to the heat radiating from the en­
g ine.
A WARNING
Do not assume the roads are free of ice based
on the outs ide temperat ure display . Be aware
that there may be ice on roads even when the
outside temperature is around 42 °F (+5 °C)
a nd that ice can increase the risk of accidents .
You can set the un its used for temperat ure,
speed and other measurements in the Info­
tainment system.
Indicator lights
Description
The indicator lights in the instrument cluster

Driving
braking effec t, which he lps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during dece lera­
tion) .
Shift effici en tly
Upshift ing earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari ­
ly.
P ress down o n the acce le ra tor peda l slowly and
avoid " kick -down ".
Avoid full acceleration
You should rare ly trave l at the maximum vehicle
speed. High speeds cause a d isproportionately
h igh inc rease in fuel consump tion, emissions and
tr affic no ise. Slower driving saves fuel.
Reduce idling time
There are benefits to stopp ing the engine, for ex ­
ample when at railroad crossings or traffic lights
with longer red lights. Stopping the engi ne for
30 -40 seconds already saves mo re fuel than the
amount of extra fuel needed to restart the en­
gine.
It takes a very long time in idle to wa rm the en­
g ine up to ope ra ting tempe ra tu re. Wea r and
emissions are especially high in the wa rm -up
phase . Therefore, yo u should begi n driving im ­
mediately after starting the engine. Avoid high
RP Ms while doing t his .
Have maintenance performed r egularly
By having m ainten ance perfo rmed regu larly on
your ve hicle, yo u can he lp to reduce f uel con­
sumpt ion befo re yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-te rm value but a l­
so impacts
fuel consumpt ion . A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Also check th e
oil level when refueling . T he oil
consumption
depends large ly on the engine load
and speed. It is normal for the oil consumpt ion
of a new eng ine to reach its lowest point only af ­
ter a certain amount of use. Therefo re, the oil
consumpt ion can o nly be properly judged after
58
approximately 3,0 00 miles (S,000 km) have been
driven .
Avoid short trips
The eng ine and exhaust clean ing system mus t
r each their optima l
operating temperature to ef­
fe ct ively reduce consump tion and emissions.
A cold engine uses a d isp roportionately high
amount of fue l. The engine reac hes operat ing
temperat ure and cons umption no rmal izes on ly
a fter approximate ly 2.5 m iles (4 km) .
Check the tire pressure
To save fuel, make sure the t ires are always in­
flated to the correct pressure ~
page 175. The
fuel consumpt ion can increase by 5% if the p res ­
s ur e is on ly 0.5 bar too low. Due to the i ncreased
rol ling resis tance, low tire p ressures w ill also
l ead to greater tire
wear and will affect driving
behavior .
Do no t drive on
winter tir es ye ar-r ound, as this
will consume up to 10% more f uel.
Eliminate unnecessary weight
S ince every po und of ext ra weight increases fuel
consump tion , a quick inspect io n of the luggage
compartmen t may be wo rth it to avoid unneces ­
s ar y we ight.
When not be ing used, a roof rack shou ld be re­
moved to decrease the w ind resistance of the ve­
hi cle. This will save yo u ap prox imately 1 2% fue l
at speeds from 62 -75 mph (100 -12 0 km/h).
Save energy
The eng ine drives the generator, which generates
e lectric ity; the fuel consumpt io n also increases
with t he demand for e lectricity . T he refore, sw itch
electrica l eq uipm ent off whe n you no longe r
need i t. Exa mples of eq uipme nt tha t uses a lo t of
energy a re air blowe rs at a high setting, the rea r
window defogger and seat heating* .
([) Note
-Do not leave engine idling un attended afte r
sta rting. If warn ing li ghts should come on
to ind icate improper ope ration, they wou ld
go unheeded . Extended idling also pro duces .,.

Trailer towing
Driving with a trailer
General information
Your vehicle is primarily intended for transport­ ing people and luggage . However, if you drive
with a trailer , follow the technical requirements,
the operation and driving tips, and the legal reg­
ulations.
Driving with a trailer affects the vehicle's fuel
consumption, performance and wear.
It also re­
quires higher concentration from the driver.
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removable ball hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle , the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol­
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Trailer towing
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys­
tem must be designed for additional load and
contain enough coolant
c::> (D .
A WARNING
-
-Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trail­
er hitch . The vehicle was not designed for
these types of trailer hitches . The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
- If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in­
creases the risk of an accident.
- To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount­
ed.
(D Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out­
side temperatures are high. otherwise, this
increases the risk of engine damage.
' Operating instructions
Several things must be noted when towing a
trailer.

The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unleaded ga soli ne.
Aud i recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gaso line can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/

Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
Yo u may use unleaded gasoline b lended wi th al­
cohol o r MTBE (commonly referred to as oxygen ­
ates) if the blended mixt ure meets the fo llowing
criteria :
Blend of ga soline methanol (wood alcohol or
meth yl alcohol)
- Anti-knock index must be 87 AK I or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more tha n 2% co -solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol )
-Anti -knock index must be 87 AK I or higher .
- Blend must not co ntai n mo re t han
15% etha-
nol.
Blend of ga soline and MTBE
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades a re blended to pe rform es­
pec ially well for w in ter o r su mme r dr iv ing . D ur ­
i ng seasonal change-ove r, we s ugges t th at yo u
fill up at busy gas stat ions where the seasona l
adjustment is more likely to be made in time.
(D Note
- Meth ano l fuels which do not meet these re­
q uirements may cause corrosion and dam ­
age to plastic and rubber com ponents in the
fuel system.
- Do not use fue ls that fa il to meet the speci­

System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A majo r concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine parts, such as fuel injectors and intake valves . Al­
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 information on TOP TIER Deter­
gent Gasoline, please go to the official website
(www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob your en­ gine of peak performance.
