2003 HONDA S2000 engine coolant

The tachometer shows the engine
speed in revolutions per minute
(rpm). To protect the engine f rom
damage, never drive with the
tachometerreadingintheredzone.
This shows the temperature of the
engine’s coolant. During normal
operation, the reading should be in
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the reading may reach near
the red mark. If it reaches the red
mark, pull saf ely to the side of the
road. Turn to page for
instructions and precautions on
checking the engine’s cooling
system.
The Select button switches the
speedometer reading between miles
perhourandkilometerperhour.It
also changes the odometer and trip
meters to read in miles or kilometers
correspondingly. To change the
readings, push the Select button and
hold it until you hear a beep.

This section covers how to set up the
system controls f or ventilation,
heating, cooling, dehumidif ying, and
def rosting.
The engine must be running f or the
heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes bef ore you f eel warm air
coming from the system.
The air conditioning does not rely on
engine temperature.
You can adjust the direction of the
air coming from the vents on both
sides of the instrument panel and at
the corner of the dashboard on the
passenger’s side. To adjust the air
flow up and down, move the tab in
the center of each vent up and down.
To adjust it lef t and right, turn the
dial under each vent lef t and right. You can shut off the air flow from
each vent by turning the dial all the
way toward the mark until it
clicks.
