B330A03A-AATTACHOMETERThe tachometer registers the speed of your
engine in revolutions per minute (rpm).

GAUGE
WARNING:Never remove the radiator cap when the
engine is hot. The engine coolant is under
pressure and could erupt and cause severe
burns. Wait until the engine is cool before
adding coolant to the reservoir.The normal range is approximately in the middle
between "H" and "C". If it moves across the dial
to "H" (HOT), pull over and stop as soon as
possible and turn off the engine. Then open the
hood and, after the engine has cooled, check the
coolant level (See "If the engine overheats" on
the page 3-4.) and the water pump drive belt. If you
suspect cooling system trouble, have your cool-
ing system checked by a Hyundai dealer as soon
as possible.
