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 needle on the engine coolant temperature
gauge should stay in the normal range. 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 check the coolant
reservoir level and the water pump drive belt. If
you suspect cooling system trouble, have your
cooling system checked by a Hyundai dealer as
soon as possible.

BRAKE PAD WEAR WARNING SOUND
The front disc brake pads have wear indicators
that should make a high-pitched squealing or
scraping noise when new pads are needed. The
sound may come and go or be heard all the time
when the vehicle is moving. It may also be heard
when the brake pedal is pushed down firmly.
Excessive rotor damage will result if the worn
pads are not replaced. See your Hyundai dealer
immediately.
