CERTAIN PASSENGER VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 208, 'OCCUPANT CRASH PROTECTION.'

What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 1998 DIAMANTE.
- Book a repair at any authorized Mitsubishi dealer. Quote NHTSA campaign 04V428000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-787-251-8715.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

EVERYTIME THE HEATER IS SWITCHED ON, I CAN FEEL A WEIRD SMELL WHICH WILL LAST FOR ABOUT 10 MINS. THIS SMELL SEEMS LIKE SUFFOCATING AND HAVE TO OPEN THE WINDOWS FOR THE FRESH AIR TO ENTER. THERE IS SOME KIND OF LEAK IN THE ENGINE COMPARTMENT, I AM NOT SURE WHERE THE LEAK IS FROM. I AM BIT WORRIED ABT THE SMELL. THANKS *TR
