3. Check the engine's oil level, following the instructions on checking and adding engine oil in this Owner Guide. (See Engine oil in the Index.) If you do not follow these instructions, you or others could be injured. To ensure an accurate reading, your vehicle should be on level ground. If the oil level is low, add as much oil as necessary before you drive your vehicle again. Do not overfill. Do not operate the engine when the oil pressure light is on, even if the oil level is correct. For more information about adding oil, see Adding engine oil in the Index. 4. Fuel Gauge The fuel gauge displays approximately how much fuel is in the fuel tank only when the ignition switch is ON. For proper fuel gauge indication after adding fuel, the ignition switch should be in the OFF position while the vehicle is being refueled. The fuel gauge indicator may vary slightly when the vehicle is in motion. With the ignition switch OFF, the fuel gauge indicator may drift from the ignition switch ON position. Speedometer The speedometer tells you how many miles (kilometers) per hour your vehicle is moving. Odometer The odometer tells you the total number of miles (kilometers) your vehicle has been driven. 104
