the timing marks on the crankshaft pulley are small about 1/4inch little "bumps" one is on the block and the other on the pulley right behind harmonic balancer pulley. there are two small "teeth" in two gear teeth, if you find those the second mark (mentioned above) is between them. As for the cam gears you have to have the back timing cover on its the small one and you can place it without bolting up. there are two slight 90 degree angles cut out of the round part of the this housing. on the left gear its at about 2:00 on the right about 10:00. and the marks on the pulley are slight indentions, like small lines. line these up and you should be good to go.
there only a set point in the timing mark alocation regarding this ,crank with the T sign from the crankshaft set point arrow sing 2 for exhaust and 3 for the inlet upward direction of the arrow last is the tensioner it only little difference for adjusting this
The Volvo has a brand circle with an arrow coming out the side.
There is one arrow etched in the side of the sprocket that look like this: > for the left side cam and for the right it looks like this: < They need to line up with the plastic timing belt cut outs

If this is the same engine as mine in a Nov '98 Holden vectra and you are talking about cam timing, the 4 bolts need to come off the crank pulley so you can see the notch that needs to line up with the notch on the sumpcasting goving TDC on No.1 cyl. cam pulley marks - lihe the INTAKE makr with the arrow cast into the plastic cam cover @12oclock to the cam and EXH mark on exhaust cam with the corresponding mark on the plastic cam cover.
The arrow light in your Volvo indicates that you are driving it as a 3 speed.You can change this by simply pushing button on side of your shifter.If you do, you change it over to a 4 speed which is best for interstate driving.I learned this by reading my Volvo 740 manual.:-) Hope this helps ya.
approx 90mph with arrow exhaust
If its an automatic then your either in winter or a low gear(not flashing) or transmission fault(flashing arrow) But if its manual the non flashing arrow is the recommended time to up shift.
