1- 58 FEATURES OF YOUR HYUNDAI B550A02Y-AAT B560A02Y-AAT HIGH-MOUNTED REAR STOP LIGHT REMOTE FUEL-FILLER LID RELEASE Fuel Cap Holder B560A02Y B550A03Y HEF-132A In addition to the lower-mounted rear stoplights on either side of the car, the high mounted rear stoplight in the center of the rear window also lights when the brakes are applied. The fuel-filler lid may be opened from inside the vehicle by pushing up on the fuel-filler lid opener located on the driver side door. ! WARNING: NOTE: If the fuel-filler lid will not open because ice has formed around it, tap lightly or push on the lid to break the ice and release the lid. Do not pry on the lid. If necessary, spray around the lid with an approved de-icer fluid (do not use radiator anti-freeze) or move the vehicle to a warm place and allow the ice to melt. o Gasoline vapors are dangerous. Before refueling, always stop the engine and never allow sparks or open flames near the filler area. If you need to replace the filler cap, use a genuine Hyundai replacement part. o If you open the fuel filler cap during high ambient temperatures, a slight "pressure sound" may be heard. This is normal and not a cause for concern. Whenever you open the fuel filler cap, turn it slowly. o Make sure the fuel filler cap is replaced and securely seated after fueling. Failure to replace or fully seat the fuel filler cap will result in fuel vapors escaping into the atmosphere and the check engine (MIL) indicator illuminating.
