1) Normal operating range
The temperature gauge shows engine coolant temper-
ature when the ignition switch is in the "ON" position.
The coolant temperature will vary in accordance with
the outside temperature and driving conditions.
We recommend that you drive moderately until the
pointer of the temperature gauge reaches near the
middle of the range. Engine operation is optimum with
the engine coolant at this temperature range and high
3-10
revving operation when the engine is not warmed up
enough should be avoided.
