symbol appears in front of the temperature dis-
play > A\.

ZA\ WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+5 °C)

tween 176 °F (80 °C) and 248 °F (120 °C) under

ature may be higher if there is heavy engine load

cause for concern as long as the E or = indica-
tor lights do not turn on.
