tion with t he
vehicle headlights off . As
the daylight fades, the instrument cluster illumi nat ion likewise dims automatically

side light is very low. This feat ure is meant
to remind you to switch on the headlights
w hen o utside lig ht con dit io ns become

Engine coolant temperature gauge
The eng ine coolant gauge q page 10, fig. 3 CD
only works when the ignition is on. To p revent
damage to you r engine, please note the fol­
lowing impor tant po ints:
Engine cold
As long as the needle remains at or close to
the bottom of the gauge, the engi ne still has
not reached its operat ing temperature . Avoid
high eng ine speeds, heavy eng ine loads and
heavy th rottle a pplicat io ns.
Normal temperature
When the engine has reached its operat ing
temperature, the needle w ill move into the
midd le of the gauge and rema in the re. If th e
engine is worki ng ha rd at high outside tem­
peratures, the needle may rise up. This is no
need to worry as long as the. warni ng lig ht
i n the i nstr ument cluster does not ill uminate.
Warning light in the instrument cluster
When the. warning lig ht in the instr ument
cluster s tarts to flash, th is can mean one of
two things : either the coo lant
temperatur e is .,..

too high, or the coolant level is too low
¢ page 32.
If the needle is well in the upper area of the
ga uge , the coolant temperature is too high.
Stop the vehicle , switch the eng ine off and
allow the engine to cool.
If the warning light
comes on again after driving a short distance,
contact an authorized dealer.
A WARNING
- Always observe the warning in
¢
page 256, before opening the hood
and checking the engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment.
You could bu rn yourself. Let the engine
cool off first until you can no longer see
or hear steam or coolant escaping.
0 Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high eng ine load , the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this cou ld reduce the cooling
effect and the engine could then over­ heat. Ask your authorized Audi dealer for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer @¢ page 10, fig. 3 is the left
of the two large clock-type displays.
The engine turns at a speed 1,000
times the
single digit in the display, e.g . if the needle is
pointing at the "2" the engine is turning at
2,000 RPM.
If engine RPM drops be low 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod. Before reaching this area , move these­
lector lever to position D (Drive) or ease your
foot off the accelerator pedal.
(D Note
The tachometer needle should not move
into the red range. If it does, then only for
a very short per iod of t i me. You could
damage your engine by driving at high RPM .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .

conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded fo r operation away
from paved roads. In situations where slip or a
differential lock ing funct ion is required, the
offroad mode can be activated
c::;, page 223.
H ill descent control is a lso ava ilable in the off­
road mode, which automat ically brakes the
ve hicl e and thereby keeps speed consta nt
when differe nt w heel speeds a re detected
when descending a hill
¢page 2 2 5. Your A ud i
a lso has permanent a ll-wheel drive in addi­
tion.
H oweve r, your Aud i is no t a pure off road ve hi­
cle. I t was not built for d riving unde r extreme
conditions, e.g. fo r trips that are in the nat ure
of an expedition .
Drive only on road s and offro ad sections
which match the de sign of y our vehicl e and
you r abilitie s as a dri ver. Ne ver t ake ri sks!
Before driving offroad
- Check the eng ine oi l level, t ire pressu re,
coolant level, and the fluid level in the w ind­
shield washe r reservo ir.
- Stow luggage items a nd other objects in the
l uggage compartment, and sec ure t hem
against s lid ing aro und.
After driving offroad
- After trips off road, remove any twigs and
othe r foreign objects from the grill, the un­
derbody and the wheels. Pay spec ia l atten­
t ion to fore ign ob jects (stones) which have
become lodged in t he tire tre ad.
- Clean t he body and the vehicle unders ide,
and inspect the veh icle for possible damage.
- Clean dirty w indows, headlamp lenses, rear
li gh ts, and license plates .
- Perfo rm a brake check (particularly after
t ravell ing throug h water).
Driving off road 235
A WARNING
- Drive especially attentively and plan
ahead in diff icu lt road conditions and
when off road. Excessive speed o r inco r­
rect maneuve rs can cause injuries and
damage to the vehicle.
-
- Always adapt your speed and driving
style to road, offroad, t raff ic, and weath­
e r condition s. D rive e spe cially slowly off­
road when yo ur view is restricted.
- Please be aware that in offroad mode,
pa rti cularly on a smoo th and s lippery
road, the whee ls may have an increased
tendency to spin and the vehicle may
break away -danger of skidding!
- Stability is limited in the offroad mode .
@ For the sake of the environment
Avoid damage to the environment and re­

road when you are driving .
The cha ins shou ld cross under the tra ile r
tongue to prevent it from dropping in case of
separation from the hitch.
0 Note
If you are going to tow a tra ile r, you must
activa te the trailer operation mode
~ page 161, Towing a trailer.
Driving instructions
Driving with a trailer always requires extra
cor e and consid eration.
To obta in the best poss ible handling of vehicle
and tra ile r, p le ase no te the following:
.. Do not tow a loaded tra iler when your car it­
self is not loaded.
.,. Be especia lly careful when pass ing othe r
vehicles .
.. Observe speed limits.
.. Do not driv e at the maximum p ermissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight di stributio n
Towing a loaded trai ler with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
l ow speeds only to avoid the risk of losing
steering control.
A "balanced" rig is eas ier to operate and con ­
trol. This means that the tow vehicle should
be loaded to the extent possible and permiss i­
ble, while keeping the trailer as light as possi­
b le under the circumstances. Whenever possi­
b le, transfer some cargo to the luggage com­
pa rtment of the tow veh icle wh ile observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permiss ible speed . Re- duce your speed even more i
f load, weather or
wind conditions are unfavorable - particularly
when going downhill.
Red uce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do not
t ry to stop the swa ying by acceleratin g.
Observe speed limits. In some a reas, speeds
f or vehicles tow ing tra ile rs are lower than for
r egular vehicles.
Always apply brakes early. When driving down hill, shift into a lowe r gear to use the en­
gine braking effect to s low the vehicle . U se o f
the brakes alone can cause them to overheat
and fail.
Coolant temperature
T he coo lant tempe ratu re gauge ~ page 10
must be observed caref ully. If the need le
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warn ing light in
the instr ume nt cluster starts flashing., pull
off the road , stop and let the engine
idle for
about two min utes to prevent heat build -up .
A WARNING "--
Anyone not proper ly restrained in a mov-
i ng vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
p rov ided by Audi .
Trailer towing tips
Important to know
Your vehicle handles d ifferently when towing
-
a trai ler because of the additional weight and
different weight distr ibut ion. Safety, perform­
ance and economy will great ly depend on how
ca refully you load your tra iler and operate
yo ur rig .
Before you act ua lly tow your tra iler, practice
turning, stopping and backing up in an area
away from traffic. Keep pract ic ing unt il you

-Apply the parking brake.
- Move selector lever to P (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances . This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
Checking and filling 257
- First, fully apply the parking brake,
move selector lever to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­
ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&. .
