Driving and Operating
2. As soon as the wait-to-start light
goes off, immediately turn the
ignition key to START. When the
engine starts, let go of the key.
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.
Notice:
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, turn the
ignition switch to LOCK/OFF.
Wait one minute for the starter to
cool, then try the same steps
again.
If you are trying to start the engine
after you have run out of fuel, follow
the steps in

.
When the engine is cold, let it run
for a few minutes before you move
the vehicle. This lets oil pressure
build up. The engine will sound
louder when it is cold.
Cold Weather Starting (Diesel
Engine)
The following tips will help with cold
weather starting.
Use the recommended engine oil
when the outside temperature drops
below freezing. See
Engine Oil on
page 10
‑

. When the outside
temperature drops below
–
18°C
(0° F), use of the engine coolant
heater is recommended.
If you experience longer cranking
times, notice an unusual amount of
exhaust smoke, or are at higher
elevations (over 2 135 m or 7,000 ft),
you may use the engine coolant
heater. See
Engine Heater on

.
If the vehicle is not out of fuel, and
the engine will not start, turn the
ignition key to ON/RUN.
Immediately after the wait-to-start
light goes off, turn the ignition key to
START.
If the light does not go off, wait a
few seconds, then try starting the
engine again. See your dealer as
soon as you can for a starting
system check.
If the light comes on and then goes
off and you know the batteries are
charged, but the engine still will not
start, the vehicle needs service.
If the light does not come on when
the engine is cold, the vehicle
needs service.
If the batteries do not have enough
charge to start the engine, see
“
Battery
”
in the owner manual.
