on and the lights are turned off. The illumina­
tion fo r the ga uges reduces automat ical ly and
eventu ally turns off as brightness outside in­

turn the low beams on at the appropriate
time.
Coolant temperature indicator
~ The coolant temperature display (D ¢ page 9,

<.,:, ' ed on. To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold ran ge
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high eng ine speeds, full ac­
celerating and heavy eng ine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on.
If the . indicator light in the instru­
ment cluster d isplay turns on, the coolant tem­
perature is too
high ¢ page 13.
@ Note
-Aux iliary headlights and other accessories in
front of the coo ling-air intake impa ir the
cooling effect of the coolant . This increases
the risk of the engine overheating dur ing
high ou tside temperatures and heavy en­
gine load.

Instrum ent s and ind icat or light s
-The front spoiler also he lps to distribute
cooling air while driving . If the spoiler is
damaged, the cooling effect w ill be im­
paired and the r isk of the engine overheat­
i ng will increase. See an author ized Audi
dealer or authorized Audi Service Fac ility for
ass istance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the speed is below 1,S00 RPM. The beginn ing of
the red zone in the tachometer indicates the maximum permissible engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before
reaching the red zone, yo u should shift into the
next higher gear, choose the Dor S se lector lever
position, or remove your foot from the accelera ­
tor peda l.
@ Note
The needle in the tachometer @ ¢ page 9,
fig. 3
may only be in the red area of the gauge
for a short time or there is a risk of engine
damage.
@ For the sake of the environment
Upshifting early he lps you to save fuel and re ­
duces operating noise.
(D Tips
Applies to: S models
The engine speed is limited when the eng ine
is cold - the full engine output is not availa­
ble. When the engine is at operating temper­
ature, the red area in the tachometer moves
to a hig her RPM range .
Fuel level
The display @ only wo rks when the ignition is
sw itched on. If the fuel level d rops below 2 .6 gal
(10 li ters), a red L ED w ill tur n on and t he
rD indi ­
cator light will turn
on ¢ page 17. The LED
blinks red when the fuel leve l is very low .

! ?) Engine speed limitation
Applies to: ve hicles with eng ine speed lim itat ion
Ill Maximum engine speed: XXXX rpm
The engine speed is automatically limited to the
speed displayed in the instrument cluster. This
protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature range and you have released the accelerator ped­
a l once.
If the engine speed limitation was activated by
an engine contro l ma lfunction, the

does not go above the speed displayed. Drive to
an author ized Audi dealer or authorized Audi
Service Facility immediately to have the malfunc­
tion corrected .

Driving
When not being used, a roof rack should be re­moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62- 7 5 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* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
ind icate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper-
ty.
@ Note
- 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 consumption 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
66
load and speed, road and weather conditions ,
trip length, etc.
Steering
Manual steering wheel position adjustment
Applies to: vehicles with manual steering wheel adjustment
The steering wheel posi tion is adjustable up and
down and forward and back .

... Bring the steering wheel into the desired posi­
tion .
.,. Push the lever against the steering column un ­
til it is secure.
A WARNING
Improper use of steering wheel adjustment
and improper seating position can cause seri­
ous personal injury.
-Adjust the steering wheel column only when
the vehicle is not moving to prevent loss of
vehicle control.
-Adjust the driver's seat or steering wheel so
that there is a minimum of 10 in (25 cm)
between your chest and the steering wheel
~page 126, fig. 138. If you cannot main­
tain this minimum distance, the airbag sys­
tem cannot protect you properly .
- If physical limitations prevent you from sit­
ting 10 in (25 cm) or more from the steer­
ing wheel, check with your authorized Audi
dealer to see if adaptive equipment is avail-
able.
