WARMING UP
When starting the engine allow it to warm up to operating temperature by allowing it to idle 5-10 minutes to ensure full
lubrication and operating temperature. Failure to do so can shorten engine life substantially.

WARMING UP IN COLD WEATHER

engine if it is not warmed up correctly.It also causes problems with the hydraulic system and the synchromesh in the transmission.
