5-8 Instruments and Controls See "Trip Odometer" under Driver Information Center (DIC) on page 5‑18 for more information. Here are three things that can happen but do not indicate a problem with the fuel gauge: . Speedometer The speedometer shows the vehicle's speed in both kilometers per hour (km/h) and miles per hour (mph). Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). At the gas station, the gas pump shuts off before the gauge reads full. It takes a little more or less fuel to fill up than the gauge indicated. For example, the gauge may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank. The gauge moves a little when turning a corner or speeding up. Odometer The odometer shows how far the vehicle has been driven, in either kilometers or miles. This vehicle has a tamper-resistant odometer. If the vehicle needs a new odometer installed, the new one is set to the mileage of the old odometer. If this is not possible, it is set at zero and a label is put on the driver's door to show the old mileage reading. . Fuel Gauge . United States Canada Trip Odometer The vehicle has a trip odometer that indicates how far the vehicle has been driven since the trip odometer was last set to zero. The fuel gauge indicates about how much fuel there is remaining in the fuel tank. The ignition must be in ON/RUN. An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on. When the fuel in the fuel tank is low, a LOW FUEL message displays on the Driver Information Center (DIC). See Fuel System Messages on page 5‑24 for more information.
