Shift efficiently
Upshift ing earlier is an effective way to save fue l.
Staying in a gear too long uses fue l unnecessari­

Press down on the acce le rato r peda l slowly and
avoid "k ic k-dow n".
Avoid full acceleration
You s hould rare ly tr ave l a t t he m axim um ve hicle

It tak es a ve ry long time in idl e to warm the en ­
gine up to o peratin g tem perature . Wear an d
emissions are especially high in the warm -up
phase. The refore, you s hould begin drivi ng im ­
med iate ly after starting the eng ine. Avoid h igh
RPMs wh ile doing this.
Have maintenance performed regularly
By hav ing maintenance pe rformed reg ularly o n

Driving
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62
-75 mph (100 -120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment
off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
(D 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 could result in overheating or
other damage to the vehicle or other prop­ erty.
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let . Lack of proper maintenance as well as
improper use of the vehicle will 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 ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
@ Tips
The consumpt ion estimates as published by
ENVIRONMENTAL 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.

.. Tilt the lever -c> fig. 83 downward¢ ,&..
.. Bring the steering wheel into the desired posi­
tion.
.. Push the lever against the steering column un­
til it is secure.
A WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the veh icle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches
(25 cm) dis­
tance between your chest and the steering
wheelr::!>page250, fig. 217. If you do not
maintain this distance, the airbag system
will not be able to provide its full protec­ tion.
c:> page 250, fig. 217.
- If your physical characteristics prevent you
from sitting at least 10 inches
(25 cm) or
more away from the steering wheel, see if
an authorized Audi dealer or authorized
Audi Service Facility can provide adapters that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision. Always make sure
that the steering wheel is level with your
chest.

Energy recovery (recuperation)
When braking, t he e lectr ic moto r will act as a
generato r creat ing elect ric energy that is then
stored in the hig h-voltage battery. This also o c­
curs when the vehicle is coasting or driving down ­
hill .
If the brakes are applied early and evenly, the
electric motor w ill brake the vehicle @
¢
page 95, fig. 98. By doing this, a large amount
of the kinetic energy is recovered and may be
stored as electric energy in the high-voltage bat­
tery . The conventional brakes are also activated
when the brakes are pressed very hard.
The strength of recuperation can depend on the
following factors:

(D Tips
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depending on driving style and operating
conditions. Consumpt io n may be h igher
dur ing the fi rst 3,000 mi les (5,000 km) . Be­
c ause of this , the eng ine o il level must be
che cked regularly.
It is best to check each
t ime you refuel your vehicle and before long
drives .
- In order to prov ide effective l ubrication and
cooling of interna l engine components, a ll
internal combustion engines consume a cer ­
tain amount of oil. O il consumption varies
from engine to engine and may change sig­ nificantly over the life of the engine. Typi­
cally, eng ines with a specif ied break-in peri­
od consume more oil during the break-in pe ­
riod than they consume after o il consump­
t ion has stabilized .
- Under normal condit ions, the rate of oil
cons umption depends on t he quality and
viscosity of the oil, the RPM (revo lutions per
mi nute) at which the engine is ope rated, the
ambien t temperature and road conditions .
Further factors are the amount of oi l dilu­
tion from water condensation or fuel resi­ due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easi ly.
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 ¢_&. .
_& WARNING
Wheel bolts that are tig htened 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
q page 364, After changing a
wheel.
- 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 yourself, 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

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.
