engaged, for examp le when you notice that the
next traffic light is red . This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during decelera­
tion) .
Shift effici entl y
Upshifting earlier is an effective way to save fuel.
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 shou ld rare ly t ravel at the maximum vehicle
speed. High speeds cause a d isp ropor tionately
high increase in fuel consumption, emissions and
traffic noise . Driving more slowly saves fue l.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles witho ut the Start/
Stop system* , it is
efficient to switch the eng ine
off when stopped at rai lroad crossings and long
red lights . Stopping the engine for
30 -40 sec ­
onds already saves more fu el than the amount of
extra fuel needed to restart the engine.
It t akes 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 .
Ha ve mainten anc e performed regularly
By having maintenance performed regu lar ly on
your veh icle, you can he lp to reduc e fuel con­
sumpt ion before you even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long -term value but al­
so impacts fuel consumption . A poorly main­
tained engine can lead to fuel consumpt ion that
is
1 0% hi gher tha n normal.
74
Avoid short trip s
The engine and exh aust clean ing system mus t
reach their optima l operating temperature to ef­
fective ly reduce consumption and emissions.
A cold engine uses a d isp roportionately high
amoun t of fue l. The eng ine re aches opera ting
temperat ure and cons umption norma lizes on ly
after approximate ly 2.5 mi les (4 km) .
Check the tire pressure
To save fue l, ma ke sure the t ires are always in­
flated to the correct
press ure~ page 335. The
fuel consumpt ion can increase by
5% if the pres ­
sure is on ly
0 .5 bar too low. Due to t he 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 fue l.
Eliminat e unnecessary weight
Since eve ry po und of ext ra weight increases f uel
consump tion, a quick inspec tion of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rack sho uld be re ­
moved to decrease the w ind resis tance of the ve­
hicle . This will save you approx imately
12% fue l
at speeds from
6 2 -75 mph (100 -120 km/h) .
Save energy
The eng ine d rives the generator, which generates
electr ic ity; the f uel consumpt ion also inc reases
wi th the demand for e lec tricity . T he refore, sw itch
electrica l eq uipment o ff when you no longe r
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 s houl d come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
h eat, which could result in overheating or
other damage to the veh icle or othe r proper­
ty .

Trail er to wing
Trailer towing
Driving with a trailer
General information
Your veh icle is primari ly intended for transport­
ing peop le and luggage. Howeve r, if you dr ive
with a tra iler , follow the techn ica l requirements ,
the operation and driving tips, and the lega l reg ­
ulations.
Dr iving w ith a trailer affects the vehicle 's fuel
consumpt ion, performance and wear. It a lso 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 removab le ball
h itch mount and ball h itch. The tra ile r hitc h must
be pe rm it t ed for the vehicle, the tra iler and the
permitted tota l weight of the trailer being
pu lled . Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mo unt a t rai ler hitch on the bumper. The
trai ler hitc h 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 regu larly if the trai ler hitc h is securely
mounted . A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If t he tra ile r has its own bra ke system, then fol­
low the manufacturer specifica tions. Howeve r,
the brake system on the trai ler must never be
connected to the vehicle brake system.
92
Engine cooling system
D riving w ith a tra ile r means a higher load on t he
engine and the cooling sys tem. The coo ling sys­
tem must be designed for additiona l load and
contain enoug h
coolant ~@ .
A WARNING -
- Never mount a "weight -distributing" or
"load-balancing" trailer coupler as the trail­
er hitch. The ve hicle was not des igned for
these types of tra iler h itches. The tra iler
h itch can malfunction and t he tra ile r can
b reak off from the vehicle.
- If t he tra ile r i s equ ipped w ith elect ronic
brakes, these brakes can not be activated by
a facto ry-installed control system, whi ch in­
creases the r isk of an accide nt.
- To red uce the r is k of injury, always remove
the ball hitch mount if no tra ile r is mo unt ­
ed.
@ Note
L onge r incl ines cannot be dr iven without a
su itab le cooli ng system, especially if the out­
s ide temperatu res a re high. ot herwise, this
i nc reases the risk of eng ine da mage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
The permitted towing capacity must not be ex ­
ceeded under any
circumstances ~ page 370.
You can dr ive up larger inclines if you are not us­
i ng the maximum towing capacity.
The towing capacities given only apply to e leva ­
tions up to 3,200 ft (1,000 m) above sea level. As
the e levation increases, the engine power de­
creases due to the decreasing air pressures. T his
reduces the hill climb ing ability and towing ca­
pac ity . For every additional 3,200
ft (1,000 m),
t h e maximum permitted tow ing weight must be
r educed by app roximately 10% . T he pe rm itted
tow ing weight is t he comb ined we igh t of the
( loaded) vehicle and the (loaded) trailer .

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power steer­
ing , power brakes , power win­
dows , power seats, radio, and
heater, to the extent that these
items are available as factory-in­
stalled equipment (whether in­
stalled or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent. Numbers of 55 or lower indicate a
low sidewall for improved steer­
ing response and better overall
handling on dry pavement .
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim.
Bead separation
means a breakdown of the bond
between components in the bead.
328
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the t ire pressure recom­
mended by the vehicle manufac­
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo ­
meters) at low speeds in the
three hour period before the tire pressure is measured or adjusted.
Curb weight
means the weight of a motor ve­
hicle w ith standard equipment in­
cluding the maximum capacity of
fuel, oil, and coolant, ai r condi­
tioning and additional weight of
optional equipment.
E x tra load ti re
means a tire designed to operate
at higher loads and at higher in­
flation pressures than the corre­
sponding standard tire. Extra load
tires may be identified as "X L",
"
l" "EXTRA LOAD" or "RF" on X I I
the sidewall. .,.

maximum specified
pressure ¢.&. -
Checking/correcting tire
pressure
~check the tire pressure at least
once per month and also check it
before every long drive .
~Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
~check the label¢ fig . 269 for
the correct tire pressure based
on vehicle load.
~correct the tire pressure if nec­
essary .
~store the new tire pressure in

-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
- Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.

Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces . These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
d isassemble them
C> _&. .
_& WARNING
Wheel bolts that are tight ened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
e> page 356, Finishing.
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourse lf, because this increases the risk
of an accident.
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions . Be ­
cause of their construction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow.
"'Use winter tires on all four wheels .
"'Only use winter tires that are approved for your
vehicle .
"'Please note that the maximum permitted
speed may be lower with winter tires
e> & in
General information on page 325.
An author­
ized Audi dealer or authorized Audi Service Fa­
cility can inform you about the maximum per­
mitted speed for your tires .
"'Check the tire pressure after installing wheels
¢page 335.
340
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.16 in (4 mm) . The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
Snow cha ins not only improve the driving in win­
ter road conditions, but also the braking.
"'Only install snow chains on the rear wheels.
"' Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer.
"'Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0 .53 in (13.S mm) in height, including
the chain lock.
You must remove the snow chains on roads with­
out snow . Otherwise, you could impair driving
ability and damage the tires .
_& WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
