344 STARTING AND OPERATING Automatic Transaxle The DRIVE range can be selected when towing. However, if frequent shifting occurs while in this range, third gear for a four-speed automatic and the fifth gear for a six-speed AutoStick should be selected. NOTE: Using third or fifth instead of DRIVE while operating the vehicle under heavy operating conditions, will improve performance and extend transaxle life by reducing excessive shifting and heat build-up. This action will also provide better engine braking. If you REGULARLY TOW a trailer for more than 45 minutes of continuous operation, then change the automatic transaxle fluid and filter according to the interval specified for "police, taxi, fleet, or frequent trailer towing" in the "Maintenance Schedule" in this manual. NOTE: Check the four-speed automatic transaxle fluid level before towing. AutoStick six-speed transmission is sealed and the fluid level cannot be checked. See your authorized dealership service center for assistance.

Cooling System To reduce potential for engine and transaxle overheating, take the following actions: • City Driving When stopped for short periods of time, put transaxle in neutral and increase engine idle speed.
