CHECK ENGINE WARNING LIGHT

The CHECK ENGINE warning light indicates malfunctions in the electronic engine control system. If functioning correctly, the light comes on when ignition switch is turned to the ON position and goes out after engine is started. If light fails to glow with ignition switch or remains on when running, service is needed.

BRAKE WARNING LIGHT

The BRAKE light indicates one of two things: either the parking brake is on or the brake fluid level is low. The light should come on briefly when ignition switch is turned to the ON position, and goes out after engine is started and the parking brake is released. If the light stays on, servicing is needed.

CHARGING SYSTEM LIGHT

Light is shown as a battery symbol on the instrument cluster. It will illuminate briefly when ignition is turned to ON or START position, and should go out when the engine starts and alternator begins to charge. If light stays on or comes on when the engine is running, the battery is not being charged and the electrical system needs service.

BATTERY VOLTAGE GAUGE

Gauge should register in the NORMAL range during operation. If gauge falls below NORMAL range during regular driving, the system should be checked.

BATTERY CHARGE INDICATOR

This feature indicates battery charging rate. During start-up or heavy electrical usage pointer may indicate discharge. Under normal driving conditions pointer should read slightly charging. If discharging is indicated during normal vehicle operation, have the electrical system checked.

ENGINE OIL PRESSURE GAUGE

Gauge indicates engine oil pressure, not the amount of oil in the engine. However, oil level may affect oil pressure. Under normal operating conditions, gauge should register within NORMAL range. If gauge drops below NORMAL operating band, stop immediately and check the oil level.

CAUTIONDO NOT operate vehicle if oil pressure gauge continues to register below NORMAL operating range.

OIL PRESSURE WARNING LIGHT

Light indicates possible low oil pressure. If light glows during regular operation, stop vehicle and check oil level. If oil level is adequate, and light remains on, have the system serviced as soon as possible.

ENGINE COOLANT TEMPERATURE GAUGE

Gauge should register within NORMAL band under regular operating conditions. If gauge rises into HOT range, stop the vehicle, let the engine cool and check the coolant level.

REAR ANTI-LOCK BRAKE WARNING LIGHT

If functioning correctly, this light comes on when ignition switch is turned to ON position and goes out after engine has started. If this light glows while driving, the rear anti-lock brake system may have a system malfunction. Repair immediately as necessary.

EMISSION WARNING LIGHT

This light is used on certain vehicles to indicate when maintenance is required for the emissions control devices. If functioning correctly, this light comes on when ignition switch is turned to the ON position and goes out after engine has started. If light glows continuously while driving, have the emissions control system serviced.

FUEL FILTER RESTRICTION LIGHT (DIESEL ENGINES)

If this light glows during normal operation, there is a restriction in the fuel filter system and the fuel filter should be changed.

WATER IN FUEL LIGHT (DIESEL ENGINES)

This light will glow when the fuel filter/separator has collected a significant quantity of water. If this light glows during operation, stop vehicle, shut off engine and drain filter bowl. Allowing water to remain in system could result in extensive damage to fuel injection system.
