Instruments and Controls

The trip odometer has a feature called the retro-active reset. This can be used to set the trip odometer to the number of kilometers (miles) driven since the ignition was last turned on. This can be used if the trip odometer is not reset at the beginning of the trip. To use the retro-active reset feature, press and hold V for at least four seconds. The trip odometer will display the number of kilometers (km) or miles (mi) driven since the ignition was last turned on and the vehicle was moving. Once the vehicle begins moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven 8 km (5 miles) before it is started again, and then the retro-active reset feature is activated, the display will show 8 km (5 miles). As the vehicle begins moving, the display will then increase to 8.1 km (5.1 miles), 8.2 km (5.2 miles), etc. If the retro-active reset feature is activated after the vehicle is started, but before it begins moving, the

display will show the number of kilometers (km) or miles (mi) that were driven during the last ignition cycle.

Fuel Range Press 3 until FUEL RANGE displays. This display shows the approximate number of remaining kilometers (km) or miles (mi) the vehicle can be driven without refueling. The display will show LOW if the fuel level is low. The fuel range estimate is based on an average of the fuel economy over recent driving history and the amount of fuel remaining in the fuel tank. This estimate will change if driving conditions change. For example, if driving in traffic and making frequent stops, this display may read one number, but if the vehicle is driven on a freeway, the number may change even though the same amount of fuel is in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving.

If the vehicle is low on fuel, the FUEL LEVEL LOW message will be displayed. See Fuel System Messages 0 114.

Average Economy Press 3 until AVG ECONOMY displays. This display shows the approximate average liters per 100 kilometers (L/100 km) or miles per gallon (mpg). This number is calculated based on the number of L/100 km (mpg) recorded since the last time this menu item was reset. To reset AVG ECONOMY, press and hold V. The display will return to zero.

Fuel Used Press 3 until FUEL USED displays. This display shows the number of liters (L) or gallons (gal) of fuel used since the last reset of this menu item. To reset the fuel used information, press and hold V while FUEL USED is displayed.

Lighting Features

Entry/Exit Lighting The vehicle has an illuminated entry/exit feature. The dome lamps come on if the E DOME OFF button is in the extended position, when a door is opened, or the key is removed from the ignition.

Battery Load Management The vehicle may have Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gauge or a voltage display on the Driver Information

Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as SERVICE BATTERY CHARGING SYSTEM. If this messages displays, it is recommended that the driver reduce the electrical loads as much as possible. See Battery Voltage and Charging Messages 0 111.

Battery Power Protection This feature shuts off the dome lamps if they are left on for more than 10 minutes when the ignition is in LOCK/OFF. This helps to prevent the battery from running down.

Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories.
