Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
The beginning 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 warm. Before reaching the red
zone, you should shift into the next higher gear,
choose the Dor S selector lever position, or re­
move your foot from the accelerator pedal.
@ Note
The needle in the tachometer may only be in
the red area of the gauge for a short per iod of
time or there is a risk of damaging the engine .
The location where the red zone begins varies
depending on the engine.
@) For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.

The roof rack must only be secured in the posi­
tioning bolt area.
Fig . SO Mount ing locat ions fo r roof rac k
If luggage or cargo is to be carried on the roof,
you must observe the following:
- Yo ur vehicle has ae rodynami c rain channels
molded in to the roof . T h is is why convent ional
roo f luggage racks ca nnot be used . We recom ­
mend using roof rails from the Aud i Genu ine
Accessories program.
- These roof rai ls are the bas is for a complete
roof rack system . For safety reasons, some ad­
ditional attachments are necessary to transport luggage, bicycles, surf boards, skis and small
boats safely . All these components are availa­
ble at yo ur authorized Aud i dealer .
- The permitted roof load for your veh icle is 165
lbs (75 kg) . The roof load is a combination of
the weight of the carrier system and the cargo .
- When using roof rack systems with a lower load
capacity, you cannot use the maximum permis­
s ible roof load . In this case, the roof rack can
o nly be loaded to the weight lim it given in the
i nstallation guide.
Inst allation
When installing the support feet, make sure they
are only placed in the positioning bolt area be­
tween the side wa ll frame and the roof frame
trim ¢
fig. 50. The positioning bolt is visible as
soon as you push the sealing lip back from the
room frame tr im us ing t he des igna ted tool.

the permissible roof load, the permissible
axle loads o r the pe rm issib le overa ll we ight

ris k of an a cc iden t.
- Please note that there is a h igher r is k of an
accident when transporting heavy objec ts or
objec ts wi th a l arge sur face on the roof r ack,
since the handling characterist ics change
due to a shift in the center of gravity or the
greater surface area exposed to the wind . So
adapt your driving and speed to the actual
conditions.

® For the sake of the environment
A roof rack is often left mounted out of con­
venience even if it is no longer used. Your ve­ hicle w ill use more fue l due to the inc reased
