The illumination for the instrument cluster lights up whenever you
switch on the ign ition with the
ve hicle hea dlight s off. As the
daylight fades, the instrument cluster illumination likewise dims
automatically and wil l go out completely when the outside light is
very low. This feature is meant to remind you to switch on th e head ­
lights when outside light conditions become poor. •
Tachometer (engine rev counter)
The tachometer indicates the engine RPM (revolutions per
minutes) .
The tachometer 0 ~ fig. 2 is the left of the two large c lock -type
displays.
The engine turns at a speed
1,000 times the single digit in the
display, e.g . if th e ne edle is pointing a t the
"2" the engine is turning
at 2,000 RPM .
If engine RPM drops below 1,500, you should downshif t to the next
lower gear . The red ar ea at the end of th e scale indica tes maximum
permissible engine RPM after the break- in period. Before reaching
th is area , shift into the next higher gear (manua l transmission),
move the selec tor lever to position "D (Drive)" (automatic) or ease
your foot off the accelerator pedal.
0 Note
T he tachometer need le should not move into the red range . If it
does, then on ly for a very short period of time . You could damage
your engine by driving a t high RPM. ...
