Maintenance recommendations TRANSMISSION MAINTENANCE Automatic transmission fluid (if equipped) The automatic transmission fluid should be checked at least once per month or every 5,000 km (3,000 miles), whichever occurs first. The correct fluid level is crucial to proper vehicle functioning. If the transmission is not functioning properly (if the transmission slips, shifts slowly or if fluid leakage occurs), the fluid level should be checked and the leakage problem corrected. Vehicles frequently operated in extreme temperatures or under fleet conditions may require more frequent maintenance. A burnt or rotten odor and dark color in the transmission fluid indicates a high temperature or sever vehicle usage. If such an odor or discoloration should develop, the transmission should be serviced immediately. For 4R70W transmissions, use only MERCON௡ fluid. For 5R55E transmissions,use only MERCON௡ V (XT-5-QM). Use of other transmission fluid may result in transmission damage, malfunction or failure. for more information on transmission maintenance, refer to Checking and adding automatic transmission fluid in the Maintenance and care chapter of the "Owner Guide". 8 DON'T ADD IF IN CROSSHATCHED AREA • CHECK WHEN HOT IDLING IN PARK
