ing. Malfunctions or req uired service proce­
dures ar e signaled audib ly and indicated by

A WARNING -
- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not . K eep in m ind
that road surfaces, espec ially br idges
and overp asses, co uld be ice covered and
slippe ry even at an outside tempe ra tu re
above 4 1 °F (+5 °C).
- Always remembe r, even if the "snow­
f lake" symbo l (ice warning) does not ap­
pear in the disp lay, black ice could be on
the road .
- A lways reduce your speed and d rive with
specia l care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
(D Tips
- If the vehicle is stationary, or if you are
dr iving at a very low speed, the tempera­
t u re s hown in the d isp lay m ight be
slightly h igher than the actual o utside
temperature. Th is is caused by the heat
being radiated from the engine .
- On vehicles with Audi Nav igat ion sys­
tem *, the displays may differ from their
normal appearance during navigation .
