WHAT TO DO IN EMERGENCIES BRAKE - Brake Warning Light • The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the parking brake is not applied, it indicates a possible brake hydraulic malfunction, brake booster problem or an Anti-Lock Brake System problem. • We recommend you drive to the nearest service center and have the vehicle serviced immediately. WARNING! Driving a vehicle with the red brake light on is dangerous. Part of the brake system may have failed. It will take longer to stop the vehicle. You could have a collision. Have the vehicle checked immediately. - Malfunction Indicator Light (MIL) • Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., may illuminate the MIL after engine start. The vehicle should be serviced if the light stays on through several typical driving cycles. In most situations, the vehicle will drive normally and not require towing. • If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic converter damage. We recommend you do not operate the vehicle. Have the vehicle serviced immediately. - Electronic Stability Control OFF Warning Light • If the ESC OFF warning light comes on continuously with the engine running, a malfunction has been detected. • If this light remains on after several ignition cycles, and the vehicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), we recommend you drive to the nearest service center and have the vehicle serviced immediately. - Charging System Light • This light shows the status of the electrical charging system. If the charging system light remains on, it means that the vehicle is experiencing a problem with the charging system. • We recommend you do not continue driving if the charging system light is on. Have the vehicle serviced immediately. - Oil Pressure Warning Light • This light indicates low engine oil pressure. If the light turns on while driving, stop the vehicle and shut off the engine as soon as possible. A chime will sound for four minutes when this light turns on. • We recommend you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately. 56
