45 minutes of continuous operation. Refer to the "Main-
tenance Schedule" in Section 8 of this manual for the
proper maintenance intervals.
NOTE:
• Check the automatic transaxle fluid level before tow-
ing.
• The six-speed automatic transaxle is sealed and re-
quires an authorized dealer to check the transaxle
fluid.
