PA1633 X3-45 Commuter Operator’s Manual
ENGINE WARM-UP
After starting the engine, keep the parking brake
applied and let the engine run at normal idle for
two minutes to allow lubricating oil to reach the
turbocharger. Increase engine speed to fast
idle, using the FAST IDLE switch located on the
dashboard for five minutes, without loading the
engine. Monitor the gauges and indicator lights
to make sure all conditions are normal. If an
abnormal condition is observed, stop the engine
immediately and have the condition corrected.
DANGER
Never let the engine run in an enclosed, non-
ventilated area. Engine exhaust fumes contain
dangerous gases which can be fatal if inhaled.
Before warming up the engine, open the
door(s) or move the vehicle outside.
NOTE
The engine will reach normal operating
temperature shortly after driving. Avoid driving
at full throttle until engine coolant temperature
reaches 140°F (60°C).
ALLISON TRANSMISSION WARM-UP
When the transmission temperature falls below
-20°F (-29°C), the CHECK telltale light
illuminates after the engine is started, and a
reminder tone will sound. In this case, the
transmission will be locked in neutral (N) until
the transmission temperature rises above -20°F
(-29°C) and the CHECK telltale light goes out.
The transmission will only operate in first or
reverse gears until it reaches normal operating
temperature.
