Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the temperature measured and
does not record the road temperature.
The outside temperature display is in the multi-
function display (
Y
page 265).
There is a short delay before a change in outside
temperature appears in the multifunction dis-
play.

Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases

injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
