STARTING AND STOPPING PROCEDURES
COLD WEATHER STARTING
The vehicle may be equipped with the optional
ether cold starting aid to facilitate cold-weather
starts when the temperature is below 35°F
(2°C). To activate the ether starting aid,
proceed as follows:
1. Before cranking engine, press the “Ether”
rocker switch on the dashboard for 3
seconds to fill the solenoid valve;
2. Release rocker switch to discharge a shot of
ether;
3. Allow 3 seconds for the shot to discharge;
4. Start engine.
Caution: Use the cold starting aid only when
absolutely necessary. Excessive use of starter
fluid could result in serious engine damage.
ENGINE BLOCK HEATER
The vehicle may be equipped with an engine
immersion-type electric block heater to assist
cold weather starting. The 110-120 VAC power
connector is located to the right, behind the
engine compartment rear doors. Connect the
female plug of an extension cord to the 110-120
VAC male outlet. Plug the extension cord into a
110-120 VAC power source only. Use the
engine block heater whenever the vehicle is
parked for an extended period of time in cold
weather and when a 110-120 VAC power source
is available.
110-120 VOLTS CONNECTOR 06390
Caution: Use only a 110-120 VAC power
source. Use only grounded (three prongs)
extension cords with a minimum rated capacity
of 15 amps. Disconnect the extension cord
before starting. Before driving, make sure the
extension cord is disconnected and the engine
compartment door is closed.
ENGINE WARM-UP
After starting the engine, keep the parking brake
applied and let the engine run at slow 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.
Warning: 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).
WORLD TRANSMISSION (WT) WARM-UP
When the transmission temperature falls below
-20°F (-29°C), the CHECK TRANS telltale light
illuminates after the engine is started. In this
case, the transmission will be locked in neutral
(N) until the transmission temperature rises
above -20°F (-29°C) and the CHECK TRANS
telltale light goes out. The transmission will only
operate in first or reverse gears until it reaches
normal operating temperature.
JUMP STARTING
In order to avoid damage to solid-state electrical
components, it is important that jumper (booster)
cables be used correctly and only in
emergencies. To jump start, use another 24 volt
DC, negative grounded, power source. Use only
jumper cables rated at 500 cranking amperes.
Warning: Injury, explosion, battery acid
damage or charging system overload may result
if these jump starting procedures are not
precisely followed.
