Installing

Installation is carried out in the reverse order, when doing this note the following:

Locate bracket for alternator, vane pump and viscous fan on cylinder block and tighten bolts in diagonal sequence:

1, 2 - M 10 x 85 bolts
3 ... 6 - M 10 x 45 bolts

Install viscous fan => Fig.
13-12
.
Install ribbed belt =>Page

.
After connecting battery, enter anti-theft code for radio

=> Radio operating instructions

Close windows fully using electric window switches.
Then operate all electric window switches again for at least one second in the "close" direction to activate the automatic one-touch function.
Set clock to correct time.
