STARTING THE ENGINE
Read all starting instructions carefully before you start your vehicle.
For temperatures below 0°C (32°F), the use of the correct grade engine
oil is essential for proper operation.
If your vehicle is equipped with a manual transmission, make sure the
parking brake is set fully before you turn the key. Depress the clutch
pedal and place the gearshift in the neutral position. The clutch must be
fully depressed in order to operate the starter. Do not press the
accelerator during starting.
If your vehicle is equipped with an automatic transmission, ensure the
gearshift lever is in P (Park) and the parking brake is set before you turn
the key. Do not press the accelerator during starting.
COLD WEATHER STARTING
Do not crank the engine for more than 30 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to OFF and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system
(see Air Cleaner Decal). Such fluid could cause immediate
explosive damage to the engine and possible personal injury.
Note:Do not add gasoline, gasohol or alcohol to Diesel fuel. This
practice creates a serious fire hazard and causes engine performance
problems.
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer toSeating
and safety restraintschapter in the owner guide.
2. Make sure the headlamps and vehicle accessories are off.
3. Turn the key to the ON position. When the WAIT TO START light
goes off, turn the key to START. (For Canadian vehicles, the daytime
running lamps will be on if the parking brake is not applied and the key
is turned to ON.)
4. When the engine starts, release
the key. The glow plugs will
continue to be activated for up to
two minutes after the WAIT TO
START light turns off. If the engine is not started before the activation
ceases, the glow plug system must be reset by turning the ignition key to
OFF.

increase engine speed until the oil pressure gauge indicates normal
pressure.)
STOPPING THE ENGINE
Turn the ignition to OFF.

5. After the engine starts, allow it to idle for about 15 seconds. (Do not
increase engine speed until the oil pressure gauge indicates normal
pressure.)
STOPPING THE ENGINE
Turn the ignition to OFF. To prolong engine life (after extended high
speed or maximum GVW operation), it is recommended that a hot engine
be allowed to operate at low idle for about 7–10 minutes which would
allow sufficient time for the turbocharged engine to cool down.
COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theGeneral
maintenance informationchapter.
At temperatures below–7°C (20°F), Number 2–D Diesel fuel may
thicken enough to clog the fuel filter. Your vehicle is equipped with an
HFCM which acts as a fuel filter/heater/water separator to keep the wax
melted which will help prevent fuel filter clogging. However, if the engine
starts but stalls after a short time and will not restart, the fuel filter(s)
may be clogged. For best results in cold weather, use Number 1–D Diesel
fuel or“winterized”Number 2–D Diesel fuel which has an additive to
minimize wax formation.
Your vehicle is also equipped with a bypass relief valve, located on the
fuel control module, which provides fuel flow to the engine if the fuel
pickup should become plugged by ice or wax. To allow this bypass valve
to function and avoid engine fuel starvation, it is recommended that,
during cold weather operation 0°C (32°F) or below, the fuel level in your
tank should not be allowed to drop below 1/4 full. This will help prevent
air from entering the fuel system and stalling the engine.
In cold weather below 0°C (32°F) your Diesel engine will slowly increase
to a higher idle speed if left idling in P (Park). As the engine warms-up,
the engine sound level will decrease due to the activation of
PCM-controlled sound reduction features.
Operation in snow
Vehicle operation in heavy snowfall or in dry loose snow that may swirl
around the front of the vehicle may feed excessive amounts of snow into
the air intake system. This could plug the air cleaner with snow and
cause the engine to stall.
Refer toAir filter restriction gaugein theDiesel informationchapter
and Engine air filter in theWarning lightschapter for more information.
