,...., -Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, ac­ tivate the parking brake and move the selec­
tor lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre ­
vent the vehicle from "creeping", you must keep your foot on the brake when the en­
gine is running and the selector lever is in D/
5 or R or "tiptronic" mode is selected .
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is running.
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with "tiptronic" .
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system .
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload . An indicator lamp
[ijJ illuminates
and a driver message appears
c> page 126
when the clutch is overloaded .
- If the engine must remain running, never
have any driving position engaged when
checking under the hood.
Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
c> page 220. Otherwise, any increase in en­
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se-
Automatic transmission
lected. This can cause the transmission to
overheat and can damage it. Activate the
parking brake or press the brake pedal to
prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances.
(!) Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the driver
when driving down decline s.
Hill descent control is activated when the selec­
to r lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
tha t is suitable for the incline. Hill descent con­
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitations. It may still be necessary to adjust the
speed with the brakes .
Hill descent control switches off once the decline
levels out or you press the accelerator pedal.
When the speed is set in the cruise control sys­
tem
c> page 95 , hill descen t control is also ac ti­
vated .
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions . Always
be ready to apply the brakes.

give you some tips on how you can he lp the envi­
ronment and your pocketbook.
(D Tips
T he consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre ­
spond to your act ual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating .
.. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler­
ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel ­
erate less . Let the vehicle coast whenever possi­
b le -for example when you see that the next traf­
fic light is red .
Avoid full throttle
Driving a t moderate speeds saves fuel and im­
proves your mileage .
.. Try and keep well be low your car's max imum
speed.
Accelerating gent ly reduces f uel consumption,
engine wear, and does not disturb the environ­
ment.
F ue l cons umption, exha ust emissions and engine
noise increase d isproportionately at high speeds.
If yo u drive at approximately three quarters of
top speed, fuel consumpt ion w ill be reduced by
one ha lf. Never drive faster than the posted
speed limit and weather conditions perm it .
Driving and the envir onment
Reducing unnecessary idling
Even when your car is just idling it burns up fuel .
.. Shut the eng ine off when you are not driving
the vehicle.
.. Do not warm up t he vehicle by lett ing the en-
gine run at idle .
The idling phase is automatically reduced for
vehicles with the Start-Stop-System*. It is effi­ c ient to sw itch off the engine in veh icles without
the Start-Stop-System* when stopped at ra ilroad
c ross ings and long red lights . T urning the engine
off fo r just 30-40 seconds saves mo re fue l th an is
bur ned by s tarti ng the eng ine again .
It takes a long time for the eng ine to warm up
fully when it is ru nning at id le. However, wea r
and noxious emissions are especially high w hen
t h e engine is war ming up. So yo u should dr ive
aw ay as soon as you star t the eng ine and avoid
runn ing at high rpms w hile the engine is sti ll
warming up .
(D Note
Do not leave eng ine idling unatt ended after
start ing. If wa rning lights sho uld come on to
i ndicate impro per operation, they would go
u nheeded. Extended idling also prod uces
heat, which could result in overheating or
other damage to the vehicle o r othe r proper­
ty .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
.. Have your vehicle serviced at regular interva ls.
By hav ing your vehicle regular ly serv ice d by an
authorized Aud i dea ler helps to ensure that it
runs properly and economically . T he cond ition o f
yo ur vehicle not on ly affects its safety and ability
to hold its value , it also affects
fuel consump­
tion .
Check your oil each time you fill your tank.
T he amou nt o f oil used is related to engine load
and speed. .,,.

conditions and off-road
General information
The operation of the Electronic Stabilization Con­
trol (ESC) is expanded for operation away from paved roads. In situations where slip or a differ­
ential locking fun ction is required , the offroad
mode can be activated ¢
page 190. Your Audi al­
so has permanent all-wheel drive in addition .
However, your Audi is not a pure offroad vehicle.
It was not built for driving under extreme condi­
tions, e.g. for tr ips that are in the nature of an
expedition .
Drive only on roads and offroad sections which
match the design of your vehicle and your abili­
ties as a driver. Never take risks!
Before driving offroad
-Check the engine oi l level, tire pressure, coo l­
ant level, and the fluid level in the windshield
washer reservo ir.
- Stow luggage items and other objects in the
luggage compartment, and secure them
against sliding around.
After driving offroad
-After trips offroad, remove any twigs and other
foreign objects from the gri ll, the underbody
and the wheels. Pay special attention to foreign
objects (stones) which have become lodged in
the tire tread.
- Clean the body and the vehicle underside, and
inspect the vehicle for possible damage.
- Clean dirty windows, headlamp lenses, rear
lights, and license plates.
- Perform a brake check (particularly after travel­
ling through water).
A WARNING
-Drive especially attentively and plan ahead
in difficult road condit ions and when off­
road. Excessive speed or incorrect maneu­
vers can cause injuries and damage to the
vehicle .
Offroad driving
-Always adapt your speed and driving style to
road, offroad, traffic, and weather condi­
tions. Drive especially slowly offroad when
your view is restricted.
- Please be aware that in offroad mode, par­
ticularly on a smooth and slippery road, the
wheels may have an increased tendency to spin and the vehicle may break away - dan­
ger of skidd ing!
- Stability is lim ited in the offroad mode .
@) For the sake of the environment
Avoid damage to the environment and re­
spect nature.
(D Tips
Only drive where it is permitted and stay on
marked roads and paths.

Offroad dri ving
- Ideal conditions do not prevai l offroad . Nev­
er utilize the maximum readings to their
fullest, always leave a safety reserve.
Driving tips
On poor rood ond offroad, there is always only
one motto: Plan ahead and drive slowly!
Pl ease observe the following when driv ing away
from paved roads:
.,. Drive only on roads and off road sections which
ma tch the des ign of your vehicle and yo ur abili ­
ties as a driver . Neve r take risks!
... Drive slowly and p lan ahead!
... Take into consideratio n the
ground clearan ce
of your veh icle.
.,. Activate the
offro ad mode Q page 190 as need­
ed .
.,. Use the
hill desc ent a ssis t Q page 192 when
driv ing down steep sections on hills .
Unpaved roads and offroad
Drive s low ly on unfam iliar roads and unknown
offroad sections, and look out for unexpected ob­
stacles (e .g. potholes, rocks, tree stumps, etc .) .
To prevent the veh icle from bottoming and avoid
damage to the underbody, you should d rive
stra ight across severe bumps in the ground with
only one side of the vehicle so that only two of
your wheels cross the b umps.
Drive briskly through sandy or marshy offroad
sections and do not stop , if at all possible .
Driving through water
Note the following to avoid vehicle damage when
driving throug h water, fo r example on flooded
roads:
- T he wate r must no t be any higher than the bot-
tom of the vehicle body .
- Do no t drive fas ter than wa lking spee d.
Driving on a slope
If you ever find yo urself not able to cl imb a s lope,
do not try to turn around, d rive back down in
re ­
verse .
Otherw ise, you run the risk of tipping over.
202 If the vehicle thre
atens to tip o ver when dr iving
across a slope, you must immediately stee r
downhill in the direction of the slope.
Do no t pa rk you r vehi cle on steep s lopes or
grades .
To reduce the risk of tipping over, drive on slopes
i n the d irect io n of the downwa rd slope (fa ll line) -
not cros swi se .
& WARNING
After driving thro ugh water, mud, slush, etc.,
the brakes may be slow to take effect beca use
of wet brake rotors and pads. Dry the brakes
f irst by braking carefu lly to restore the full
braking effect .
(D Note
- Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be seve rely damaged by driving
throug h water.
-Always switch off the Start-Stop-System *
when driving through water Qpage 93.
(D Tips
-Check the de pth of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or
switch the engine of f whe n driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep fo r your vehicle to drive
t h roug h safe ly.
-Avoid driv ing through salt water beca use it
can cause corrosion.

Tr aile r to wing weights
With a f ac tor y-inst all ed or an a ft er ma rket trailer
h itch, the maximum permissib le trailer weight is
4,400 lbs (2,000 kg) . The maximum perm iss ible
unb raked trailer weight is 1,650 lbs (750 kg) .
These spec ificat ions apply when dr iv ing on roads
hav ing an incl ine of less tha n 12%.
Perm is sible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maxim um allowable or
slightly lower. You can get an approx imation of
the tongue load w ith a bathroom scale or you can
measure the load at a tr ucking company or
weighing station.
W ith a
fa ctor y-installed or an aftermarket trailer
h itch, t he maximum permissib le load on the ball
h itch may not exceed 440 lbs (200 kg).
It is rec­
ommended to use the maximum permissible
load.
Trailer load di stribution
B e su re the load in the trailer is held securely in
p lace to prevent it from s hift ing fo rwa rd, back ­
ward or sideways.
Nev er allo w a p assenge r to ride in a trail er c::> A

Ball mount
The trailer hitch may only be used w ith suitable
ball mount and ball
c::> fig. 189 . Installat ion of
the hitch ball must be carr ied out in accordance
w ith the manufacturer 's inst ruct ions.
204
Engine cooling system
Towing a tra ile r makes t he engine work harder. It
is important that the cooling system's perform­
ance is up to the additional load . Make sure that
the cooling system has enough fluid .
Tire pressure
When towing a t railer, inflate the ti res of your
vehicle to the cold tire pressure listed under "Full
l oad" on the tire press ure label. The tire pressure
l abel is located on the driver 's side B-pillar . In­
flate tra iler tires to trailer and tire manufactur­
ers' specifications.
Lights
The head light settings shou ld be checked with
the trailer attached before driving off. Check to
make s ure both vehicle and trailer lights are
working properly.
Safety chains
Be sure tra ile r safety cha ins a re properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit tu rn­
i ng corners . When you install safety chains, make
s u re they will not drag on the road when you are
driv ing.
The chains should cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
To obtain the best possible handling of veh icle
and t railer, p lease note the following:
.., Do not tow a loaded trai ler when your car itself
is not loaded.
.., Be especially care ful when passing other
vehicles .
.., Observe speed limits.
.., Do not drive at the maximum permissible
speed.
.., Always app ly brakes early.
.., Monitor the temperature gauge.

Fuel and R efu eli ng
Gasoline additives
Applies to veh icles: w ith gaso li ne engine
A major concern among many auto manufactur­
ers is carbon deposit build- up ca used 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 gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l 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 pe riod of using inadequate
fue ls, built-up carbon depos its can rob your en­
gine of peak performance.
(D Note
- Damage or ma lfunction due to poor fue l
quality is not covered by the Audi New Vehi­
cle Limited Warranty.
- Do not add aftermarket fuel additive prod­
ucts to yo ur fuel tank.
Diesel fuel
Applies to veh icles: w ith d iese l e ngine
Always use ULSD (Ultra Low Su lfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM D97S.
Diese l fuel with concentrations of biodiesel high­
er than S % such as 811,820 or 8100 are strictly prohibited.
