Driving and Operating
Before Starting the Engine
1. The priming pump (1) is located on the
outboard side of the left frame rail,
behind the diesel exhaust fluid (DEF)
tank. Place a container beneath the drain
plug to receive fuel, and then fully
loosen the drain plug (2) to drain out
water.
2. Fully retighten the drain plug (2) and
wipe off any fuel that may have adhered
to the plug or surrounding area.
3. Pump the priming pump (1) back and
forth approximately 290 to 340 times
until resistance is felt and the handle
cannot be pumped anymore.
4. Start the engine.
5. If the engine does not start, repeat steps
3 and 4 as necessary until it does start.
After Starting the Engine
1. Without pressing the accelerator pedal,
start the engine.
2. After the engine has started, allow it to
idle for about 5 seconds.
3. Fully press the accelerator pedal and
increase the engine speed to the
maximum speed for 10 seconds. (Repeat
this operation several times.)
Insufficient air bleeding can result in faulty
engine operation. Be sure, therefore, to
always carry out the procedure described in
"After Starting the Engine".
Filling the Tank
Be sure to obey the following instructions
when refueling the vehicle:
.
Stop the engine and close the vehicle's
doors and windows.
.
Keep cigarettes and other flames away
from the vehicle.
.
Before opening the fuel tank filler cap,
touch a metallic object to discharge static
electricity from your body.
.
When filling, place the nozzle deeply into
the fuel tank. If you try to fill more fuel
by pulling out the nozzle from the fuel
tank, the fuel may spill out, thus causing
danger.
.
Be sure to wipe off the fuel that is spilled
at refueling.
{
Warning
Fuel vapor is highly flammable.
Be careful not to inhale fuel vapor when
refueling the vehicle.
If you have a static charge buildup on
your body while refueling the vehicle, a
spark caused by its discharge could ignite
the fuel, resulting in burns.
All parts of the refueling procedure (from
opening the fuel tank filler cap to
completing the refueling and closing the
fuel tank filler cap) must be performed
by the same person.
Other people may be carrying static
electricity. Do not allow them to
approach the fuel filler.
