A WARNING
--- Never rely exclusively on the outside tem­ pe ratu re d isplay to dete rm ine if a road sur­
face is icy or not. Keep in mind that road sur­
faces, espe cially bridges and overpasses,
could be ice covered and slippery even at an
outside temperature above 41 °f (+S °C).

the chance of encountering icy road surfaces
increases.

If the vehicle is stationary, or if yo u are driv­
ing at a very low speed, the temperature
shown in the disp lay might be slightly higher
than the actual outside temperature . This is

nostic (OBD II) system.
The warning/indicator light illuminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the light does not go out after the engine is
started, or illuminates while you are driving, a malfunct ion may exist in the engine system. If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
