Here are four things that some owners ask about. All these things are normal and do not indicate that anything is wrong with the fuel gage. Service Traction System Warning Message • At the gas station, the gas pump shuts off before the gage reads full. • It takes a little more (or less) fuel to fill up than the gage reads. For example, the gage reads half full, but it took more (or less) than half of the tank's capacity to fill it. • The gage pointer may move while cornering, braking or speeding up. United States Canada • The gage may not indicate empty when the ignition is turned off. Message Center The message center is located in the instrument panel cluster at the bottom of the tachometer. It gives you important safety and maintenance facts. If your vehicle has the traction control system and this message is displayed when you're driving, there may be a problem with your traction control system. Your vehicle may need service. When this message is displayed, the traction control system will not limit wheel spin. Adjust your driving accordingly. If there's an engine-related and brake system problem that is specifically related to traction control, the traction control system will turn off and the warning message will come on. If the traction control system warning message comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service. 3-43
