temperature outside due to the heat rad iat ing from the engine .
T he unit of measurement for the temperature can be set in either °F

ature display automatically shows the unit o f measurement that has
been set. For ad ditio nal info rmation, see t he MM I* or the r adio

• Never use the outside temperatu re display to determine if a
road surface i s ic y or not . Keep in mind that road surfaces, espe­
cially bridges and o verpasses , could be ice covered and slippery
even at an out side temperature above 41 °F (+5 °C ).

[I) Tips
• If the vehicle is s tat io nary, o r if you are d riving a t a very low speed,
the temperature shown in the disp lay might be slightly higher than
