will move to the middle o f the gauge and remain ther e. I f t he engine
is working hard at high outside temperatures , the needle may move
higher on the gauge. This is not a cause for concern as long as the

controlled by a light sensor located in the instrument panel. The
instrument panel illumination will automatically become dimmer
as the daylight fades away and eventually will go out completely
when outside light is very low. This is to remind you, the driver, to
switch on the headlights before it gets too dark.

regardless of the intensity of ambient light . Always be aware of
changes in outside light conditions while you are driving. Respond
in time to fading daylight by turning the light switch to position
