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.
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).
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.
ALLISON TRANSMISSION WARM-UP
With an automatic transmission, when the
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.
STARTING THE VEHICLE AFTER A
FIRE ALARM
The vehicle may be started after a fire alarm
without resetting the system. Refer to Section 7
SAFETY FEATURES AND EQUIPMENT under
