Instruments and Controls 5-45 Engine Power Messages ENGINE POWER IS REDUCED This message displays and a chime may sound when the cooling system temperature gets too hot and the engine further enters the engine coolant protection mode. See Engine Overheating on page 10‑26 for more information. This message also displays when the vehicle's engine power is reduced. Reduced engine power can affect the vehicle's ability to accelerate. If this message is on, but there is no reduction in performance, proceed to your destination. The performance may be reduced the next time the vehicle is driven. The vehicle may be driven at a reduced speed while this message is on, but acceleration and speed may be reduced. Anytime this message stays on, the vehicle should be taken to your dealer for service as soon as possible. Fuel System Messages FUEL LEVEL LOW This message displays and a chime may sound if the fuel level is low. Refuel as soon as possible. See Fuel Gauge on page 5‑16 and Fuel on page 9‑79 for more information. Key and Lock Messages REPLACE BATTERY IN REMOTE KEY This message displays if a Remote Keyless Entry (RKE) transmitter battery is low. The battery needs to be replaced in the transmitter. See "Battery Replacement" under Remote Keyless Entry (RKE) System Operation on page 2‑3. TIGHTEN GAS CAP This message may display along with the check engine light on the instrument panel cluster if the vehicle's fuel cap is not tightened properly. See Malfunction Indicator Lamp on page 5‑24. Reinstall the fuel cap fully. See Filling the Tank on page 9‑83. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn this light and message off. Lamp Messages TURN SIGNAL ON This message displays and a chime sounds if a turn signal is left on for 1.2 km (0.75 mile). Move the turn signal/multifunction lever to the off position.
