NOTE: Your vehicle should not be driven until some fluid has been added if the fluid level is below the bottom hole on the dipstick and the outside temperature is above 50˚F (10˚C). Add only enough fluid to bring the level above the bottom hole. If the vehicle has not been driven and the fluid level is above the bottom hole on the dipstick, do not add fluid. Recheck the fluid level after your vehicle has reached normal operating temperature. Normal operating temperature is reached after driving approximately 20 miles (32 km). The fluid level should be within the crosshatched area on the dipstick. NOTE: If the vehicle has been operated for an extended period at high speeds, driven in city traffic during hot weather, or has been pulling a trailer, the vehicle should be turned off for about 30 minutes to allow the fluid to cool before checking. Adding Automatic Transaxle Fluid Before adding any fluid, be sure that the correct type will be used. Correct type is shown on the dipstick. Add fluid in 1/2 pint (.25L) increments through the filler tube to bring the level within the crosshatched area on the dipstick. If the level is above the top hole on the dipstick, excess fluid should be removed by a qualified technician. 298
