The illum inat ion for the instrument cluster lights up whenever you
switch o n the ignition with the
vehicle headlight s off. As the daylight
fades, the instrument cluste r illum ination likewise d ims automati­
cally and w ill go out completely when the outside light is very low .
T his featu re is mean t to remind you to switch on the headligh ts when
outs ide light conditions become poor .•
Engine coolant temperature gauge
The engine coo lant gauge ~ fig . 2 © only works when the ignition is
on. To p revent damage to yo ur engine, ple ase note the following
important po ints:
Engine cold
As long as the need le remains at the le ft end of the gauge, the engine
st ill has not re ached its operating tem perature. Avoid high eng ine
speeds, heavy engine loads and heavy throttle applicat ions.
Normal temperature
When the eng ine has reached its ope rating temperature, the needle
w ill move into the midd le of the gauge and remain t he re.
If the
eng ine is working hard at high outs ide temperatures, the needle may
go furthe r to the right. This is no need to wo rry as long as the _JL
wa rning light in t he instrument cluster does not illuminate .
Warning light in the instrument cluster -t
When the _ L warning light starts to flash, this ca n mean one of two
t hings: e ither the cool ant
temperature is too h igh, or the coolant
level is too low=> page 29. _,.
