Speedometer and Odometer Your speedometer lets you see your speed in miles per hour (mph) or kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). The speedometer shows a top speed of 140 mph (220 km/h). This is not intended to be the vehicle's top speed. Your vehicle is equipped with a tamper resistant odometer. If you see ERROR displayed, you will know that someone has probably tried to turn it back. You may wonder what happens if your vehicle needs a new odometer installed. If the new one can be set to the mileage total of the old odometer, then it must be. But if it cannot, then it is set at zero and a label must be put on the driver's door to show the old mileage reading when the new odometer was installed. Trip Odometer The trip odometer can tell you how far you have driven since you last reset it. To set it to zero, press the trip reset button next to the instrument panel cluster on the right side. 3-39
