Oil pressure warning light
Warning light (low oil pressure)
The vehicle is equipped with a warning light on the
instrument panel that lights up when the key is
turned to the «ON» position. However, this light
should switch off once the engine has been star-
ted.
If the light comes on during braking, at idling
speed or while turning, it is necessary to first
switch off the engine and then to check the oil
level and the lubrication system
Checking the valve clearance

the references between the cam shaft control pul-
ley and head.

the valve and register screw correspond to the in-
dicated values. If the clearance does not corre-
spond, adjust it by loosening the lock nut using a
screwdriver on the set screw as shown in the fig-
ure.
