The fluid level must be above the lower mark. If it is not, you should not drive your vehicle until more fluid is added. Ideally, the fluid level should be within the specified area of the dipstick. NOTE: The fluid level indication on the dipstick will be different at operating temperature and room temperature. For the correct fluid level reading on the dipstick, follow the appropriate instructions. At normal operating temperature (approximately 20 miles [32 km] of vehicle operation), the level on the dipstick should be within the specified area on the "Safe level when hot" temperature scale. At room temperature, the level should be within the specified area on the "Safe level when cold" temperature scale. If your vehicle has not been operated for some time and outside temperature is below 50˚F (10˚C) the fluid must be warmed by running the engine.
