from the engine. Do not race
the engine immediately after
starting it. Operate the engine
and transmission gently until
the oil warms up and lubricates
all moving parts.
Diesel Engine Starting Procedure
The diesel engine starts differently
than a gasoline engine.
1. With the Keyless Access
system, the RKE transmitter
must be in the vehicle. Press
ENGINE START/STOP and
observe the wait-to-start light.
See Wait-to-Start Light 0 131.
This light may not come on if
the engine is warm.
2. As soon as the wait-to-start
light goes off, immediately
press ENGINE START/STOP
with the brake pedal applied to
start.
The engine has a fast warm-up
glow plug system. The
wait-to-start light will illuminate
for a much shorter time than
most diesel engines, due to the
rapid heating of the glow plug
system.
Caution
If the wait-to-start light stays on
after starting the vehicle, the
vehicle may not run properly.
Have the vehicle serviced
right away.
3. If the engine does not start
after 15 seconds of cranking,
wait one minute for the
cranking motor to cool, then try
the same steps again.
If you are trying to start the engine
after the vehicle has run out of fuel,
follow the steps in Running Out of
Fuel (Diesel) 0 240.
When the engine is cold, let it run
for a few minutes before driving.
This lets oil pressure build up. The
engine will sound louder when it
is cold.
Driving and Operating
Cold Weather Starting (Diesel
Engine)
Use the recommended engine oil
when the outside temperature drops
below freezing. See Engine Oil
0 263. When the outside
temperature drops below 18°C
(0°F), use of the engine heater is
recommended.
See Fuel for Diesel Engines 0 233
for information on what fuel to use in
cold weather.
If the Diesel Engine Will Not
Start
If the vehicle has run out of fuel, see
Running Out of Fuel (Diesel) 0 240.
If the vehicle is not out of fuel, and
the engine will not start:
Press ENGINE START/STOP.
Immediately after the wait-to-start
light goes off, press ENGINE
START/STOP to start the vehicle.
If the light does not go off, wait a
few seconds, then try starting the
engine again. See your dealer for a
starting system check.
