-Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
-Avoid driving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
The amount of fuel consumption, the environ
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap
proximately 10-15%. The following tips will help
you conserve the environment and your money at the same time.
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a
gear
engaged, for example, 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
sumption to zero (fuel shut-off during decelera
tion) .
Shift efficiently
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fuel unnecessari
ly .
Press down on the accelerator pedal slowly and
avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles without the Start/
8 Stop system*, it is efficient to switch the engine 00 \.J '
off when stopped at railroad 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 engine.
It takes a very long time in idle to warm 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 doing this .
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con
sumption before you even start to drive. 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 consumption that
is 10% higher than normal.
Avoid short trips
The engine and emissions control system must
reach their optimal operating temperature to ef
fectively reduce consumption and emissions .
A cold engine uses a disproportionately high amount of fuel. The engine reaches operating
temperature and consumption normalizes only
after approximately
2 .5 miles (4 km) .
Check the tire pressure
To save fuel, make sure the tires are always in
flated to the correct pressure
Q page 215. The
fuel consumption can increase by S% if the pres
sure is only 0.5 bar too low . Due to the increased
rolling resistance, low tire pressures will also
lead 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
Since every pound of extra weight increases fuel
consumption, a quick inspection of the luggage
compartment may be worth it to avoid unneces -
sary weight.

Driving sa fety
,.. ALWAYS adjust your speed to road, traffic and
weather conditions.
,.. Take frequent breaks on long trips. Do not drive
for more than two hours at a stretch.
,.. Do NOT drive when you are tired, under pres
sure or whe n you are stressed .
A WARNING
Impaired driv ing safety inc reases the risk of
ser ious persona l inju ry and death whenever a
vehicle is being used.
Correct passenger
seating positions
Proper seating position for the driver
The proper driver sea ting po sition is impor tan t
for safe, relaxed driving .
Fig. 14 0 Correc t seat ing posit ion
F or your own safety and to reduce the risk of in
jury in the event of an accident, we recommend
that you adjust the driver 's seat to the following
position :
,.. Adjust the dr iver's seat so tha t you can easily
push the pedals all the way to the floor whi le
keeping your knee(s) s light ly
bent ¢ ,A.
,.. Adjust the angle of the seatback so that it is in
an upright position so that your back comes in
full contact with it when you drive.
,.. Adjust the steering wheel so that there is a dis
tance of at least 10 inches (25 cm ) between the
stee ring wheel and your breast
bone ¢ fig. 140 .
If not possib le, see you r autho rized Aud i dea l
ersh ip about adaptive equipment .
130
,.. Adjust the steering wheel so that the steering
wh eel and airbag cover points at your chest and
not at your face.
,.. Grasp the top of the steering wheel with your
elbow(s) slightly bent.
,.. F or ad justab le head rest raints: Adjust the head
restraint so t he upper edge is as even as possi
ble with the top of your head . If that is not pos
sible, t ry to adjust the head restraint so tha t it
is a s close to this pos it ion as poss ible . M ove the
he ad restraint so tha t it is as close to the back
o f the head as possible.
,.. Fasten and wear safety belts correctly
¢ page 141 .
,.. Always keep both feet in the footwell so that
you are in contro l of the veh icle at all times .
Fo r detail ed information on how to adjust the
dr iver's seat,
see ¢ page 47.
A WARNING
Drivers who are unbelted , out of position or
too close to the airbag can be seriously in-
jured by an airbag as it unfo lds . To help re-
duce the risk of serio us pe rsonal i njury:
-Always adjust the driver's seat and the steer ing whee l so that there are at least
10 inches (25 cm) between you r breastbone
and the steering wheel.
- Always ad just the driver's seat and the
steer ing whee l so that the re are at least
4 inch es (10 cm) between the knees a nd the
lower part of the ins trumen t panel.
-Always hold t he s teering wheel on the out
side of t he steering wheel r im with yo ur
hands at the 9 o'clock and 3 o'clock posi
tions to help reduce the risk of personal in
jury if the dr iver 's airbag inflates.
-Never hold the stee ring wheel at the
12 o'clock position or with you r hands at
other positions inside the steer ing whee l
rim o r on the steering wheel hub. Holding
the steering wheel the wrong way can cause
serious injuries to the hands, arms and head
-
if the driver's airbag inflates . .,_

~ Make sure that the rear seatback is securely
latched in place.
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per
sonal injury in the event of hard b raking or an
accident . To help reduce the risk of serious
personal in jury:
- Always put objects, fo r example, luggage o r
other heavy items in the luggage compart
ment.
- Always sec ure objects in the luggage com
partmen t using the tie-down hooks an d
s u itable straps.
A WARNING
Heavy loads wi ll influence the way yo ur vehi
cle handles. To he lp reduce the ris k of a loss
of contro l leading to serio us pe rsonal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
- Always d istribute the load as evenly as
possible.
- Place heavy objects as far forward in the
luggage compartment as poss ible .
- Never exceed the Gross Axle Weight Rating or the Gross Vehicle Weight Rat ing specified
on the safety compliance sticker on the driv
er's side B-p illar. Exceeding permissible
we ight s tanda rds can cause the vehicle to
slide and handle differently .
- Please obse rve information on safe driving
~page 1 2 9.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed wh ile driving.
- Never transport objects larger than those
fitt ing completely into the luggage area be
cause the rear lid can not be fully closed.
-
Dri ving saf ety
- If you absolutely m ust dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Open all a ir outlets in the instrument pan-
el,
- Switch
off the air rec irculat ion,
- Set the fresh air fan to the highest speed.
A WARNING
=
A lways make su re that the doo rs, all win-
dows, the powe r roof* and the rea r lid are se
curely closed and locked to reduce the r isk of
i njury when the veh icle is not being used .
- After closing the rear lid , always make sure
that it is properly closed and locked .
- Never leave your veh icle unattended espe
cially with the rear lid left open . A child
could crawl in to the vehicle th rough the lug
gage compartment and close the rea r lid be
coming trapped and unab le to get o ut. Be
ing trapped in a vehicle c an le ad to ser ious
pe rsonal injury.
- Never let children play in o r around the vehi
cle .
- Never let passengers ride in the luggage
compa rtment. Vehicle occupants mus t al
ways be p roperly restrained in one of the ve
h icle's seat ing pos itions.
(D Tips
- Air circulation helps to reduce w indow fog
ging. Stale air esc apes to the outs ide
t hrough vents in the tr im panel. Be sure to
keep these slots free and open.
- The tire p ressure m ust co rres pond to the
load. The t ire pressure is shown on the tire
pressure label. The t ire pressure label is lo
cated on the dr iver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures fo r the veh icle at its
maximum capac ity weight and the tires that
we re on your vehicle at the time it was man
ufac tured . For recommended t ire pressures

Wheels and Ti re s
General information
.,,.Check your tires regularly for
damage (punctures, cuts , cracks
and bulges). Remove foreign ob
jects from the tire tread .
.,,. If driving over curbs or similar
obstacles, drive slowly and ap
proach the curb at an angle.
.,,. Have faulty tires or rims re
placed immediately .
.,,.Protect your tires from oil ,
grease and fuel.
.,,. Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled .
.,,.Lay tires flat when storing and
store them in a cool, dry locat ion
with as litt le exposure to light as
possible .
&_ WARNING -
-Never drive faster than the
maximum permitted speed
for your tires. This could cause the tires to heat up too much .
This increases the risk of an
acc ident because it can cause
the tire to burst.
-Always adapt your driving to the road and traffic condi-
Wheels
tions. Drive carefully and re
duce your speed on icy or slip
pery roads . Even winter tires
can lose traction on black ice .
@ N ot e
-Please note that summer and
winter tires are designed for
the condit ions that are typical
in those seasons. Audi recom
mends using winter ti res dur
ing the winter months. Low
temperatures significantly de crease the e lasticity of summ
er tires , which affects traction
and braking ab ility . If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be
used in winter driving condi
tions . The surface of the rims
does not have sufficient corro
sion protect ion for this and
could be permanently dam
aged by road salt or similar
substances.

New tires or wheels
Audi recommends having all work
on t ires or wheels performed by
an authorized Audi dealer or au
thorized Audi Service Facility.
These facilities have the proper
know ledge and are eq uipped with
the required too ls and rep lace
ment parts.
1>- New tires do not yet have the
optim um gripping properties.
Drive carefully and at moderate
speeds for the first 35 0 m iles
(500 km) with new tires .
1>-Qnly use tires with the same de
sign, size ( rolling circumfer
ence) , and as close to t he same
tread pattern as possible on a ll
four wheels .
.,.Applies to: RS models: only use
tires with the same design, size (ro lling circumfere nce), and the
same tread pattern on all four
whee ls.
1>- Do not replace tires individually.
At least replace bo th tires on the
same axle at the same time .
