Refer to the Maintenance Schedule to determine what

fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7‑8.
3. After adding fluid, recheck the fluid level as
described under “How to Check Automatic
Transmission Fluid” earlier in this section.
