Engine speed
To achieve better performance with increased engine serv-
ice life, it is wise to maintain correct engine speed.
1. The engine has less pulling power in the engine speed
areas below the green zone. High load at low engine
speeds increases fuel consumption and the risk of over-
heating.
2. Inside the green zone, optimum pulling power and fuel
economy will be obtained. When driving, the engine
speed should be kept in this zone as much as possible.
Inside the green-striped engine speed zone the pulling
power is also high, but the fuel economy somewhat low-
er.
3. Never let the needle go into the red.
Turbo pressure ”econometer” (option)
Indicates overpressure in the engine intake manifold. When
driving on level roads the pointer should remain on a low
level (wide green zone) for best fuel economy.
Fuel level
States the relative amount of fuel in the fuel tank. Fuel tank
volume and the fuel tank location may vary between differ-
ent models.
