.When going down on a steep
slope, avoid driving the vehicle
backward as much as possible.
Drive it forward slowly on the
down slope.
. Compared with forward
movement, the braking distance
of backward movement is longer,
and the steering response of
that is worse.
. If you must drive the vehicle
backward, drive it very carefully
and gradually by moving and
stopping repeatedly in order to
stop it any time.
Engine Brake : Engine brake is the
braking effect that occurs when you
release the accelerator pedal while
driving. The lower the gear, the
stronger the engine brake.
Exhaust Brake : The exhaust brake
is a system that closes the exhaust
pipe and uses the force of the
exhaust emissions to enhance the
effectiveness of engine brake. Overrunning :
An engine overrun is
an engine-speed increase that
causes the tachometer needle to
enter the red zone. It is dangerous
because it can cause engine failure.
Winter Driving
Recommendations for Driving
in Cold Regions
The following recommendations
apply to snowbound regions and to
mountainous regions, ski resorts
and other areas of extreme cold
and/or snowfall. Please follow them
also for reference in winter in other
regions.
For the sake of your vehicle, make
the winter preparations described in
the links below. Also have these
preparations made before driving to
a cold region.
See Engine Oil 0245.
See Engine Coolant 0253.
See Washer Fluid 0262.
See Battery - North America 0269.
When Ice Prevents You from
Putting Your Key in the Door
or Opening the Door
If you try to force the key into the
door, you could bend it. And if you
try to pull the door open with undue
force, the rubber seal around the
door could come unstuck or become
damaged. Use warm water to melt
the ice, then quickly wipe it away
and open the door.
If the wipers, electric door mirrors,
or power windows freeze up, also
use warm water to melt the ice and
then operate the system. Otherwise,
you could damage the mechanism
and drain the battery. After that,
wipe the water away.
Before Driving in Cold Regions
Getting In and Out of the Vehicle
The step can get icy in cold regions.
Be careful not to slip when getting in
and out of the vehicle.

Caution
After starting the engine, do not
turn the engine control switch to
the START position. Otherwise,
the starter motor may be
damaged.
Using electrical devices such as
the audio system for an extended
time period with the engine
stopped can completely discharge
the battery.
The starting circuit, engine alarm
circuits and accessory circuits are
all controlled by the engine control
switch.
1 LOCK : Lock is in the position
fully counterclockwise. In this
position, the key can be inserted or
removed. To place the engine control switch in the LOCK position,
press and hold the key in the ACC
position and then turn it to the
LOCK position. If you will leave the
vehicle, remove the key and turn the
steering wheel until it locks. The
steering wheel will be locked to help
prevent theft.
2 ACC :
Accessory is in the first
position clockwise. In this position,
the audio and other accessories can
be used with the engine stopped.
3 ON : This ON position is in the
second position clockwise. The key
stays in this position while the
engine is running. Engine control,
warning circuits, gauge circuits, and
accessory circuits are energized.
The engine cylinder heaters or glow
plugs are also turned on when the
switch is in the ON position. The
wait-to-start light will come on and
stay on until the glow plugs are
heated enough. When this light
goes off, turn the switch to the
START position.

Driving and Operating 169
Starting the Engine
Do not keep the engine control
switch in the START position for
more than about 10 seconds.
Operating the starter for too long
might cause starter and battery
failure or may result in overheating.
When the engine does not start,
wait for 20 to 30 seconds and then
turn the engine control switch again.
Before starting the engine sit in the
driver seat, check that the parking
brake is firmly engaged, the selector
lever is in the P or N (P is preferred)
position and the shift indicator also
shows P or N, and firmly press the
brake pedal to start the engine.
When stopped on a slope, start the
engine with the selector lever in the
P position. SeeIgnition Positions
0 166.
1. Make sure that the selector lever is in the P or N position
and firmly press the brake
pedal.
2. When the engine control switch
is turned to the ON position,
the wait-to-start light comes on
and it goes out in about
1 second when the engine is
warm, to about 10 seconds
when the engine is cold.
3. After confirming that the wait-to-start light has gone out,
turn the engine control switch
to the START position to start
the engine. Release the engine
control switch as soon as the
engine starts.
4. Do not crank the engine for more than 10 seconds at a
time. If the engine does not
start, wait 20 to 30 seconds
with the engine control switch
in the LOCK or ACC position
before trying to start again. It is normal for the vacuum warning
buzzer to sound for a few seconds
after the engine has started.
After the engine has started, check
to be sure the selector lever is still
in the P position.
This engine has an automatic
warm-up system that increases
engine idle speed and applies the
exhaust brake. Allow sufficient time
to let the engine circulate lubricant
oil before driving. This usually
requires 30 seconds to 2 minutes
depending on ambient conditions.
See
Brake System Warning Light
(Parking Brake Light) 074.
The turbocharged engine should be
started in a way which ensures the
bearings supporting the rotating
parts of the turbocharger are
sufficiently lubricated. Do not race a
cold engine.
At low ambient temperatures, a cold
engine may emit more smoke than
usual.
Do not drive the truck until the
engine has had sufficient time to
circulate the lubricant oil. This

3. Always refuel at the end of aday's operation. Moisture will
condense in an empty tank;
therefore, the tank should be
filled before leaving the vehicle
standing for an extended
period.
Do not use starting aids in the air
intake system. Such aids can cause
immediate engine damage. See
Fuel for Diesel Engines 0227.
Stopping the Engine
When stopping the engine, take the
following steps: 1. Bring the vehicle to a complete stop.
2. Firmly apply the parking brake.
3. Move the selector lever to the P position and make sure that
the shift indicator shows P.
4. Allow the engine to idle for approximately 3 minutes.
5. Turn the engine control switch to the ACC or LOCK position. Do not shut down the engine
immediately after driving the vehicle.
Otherwise, a seizure or other
failures may result.
To prevent the battery from going
dead, turn the engine control switch
to the ACC or LOCK position after
stopping the engine. If you leave the
vehicle for an extended period of
time, place the engine control switch
in the LOCK position.
Let the engine idle for 3 minutes
before shutting off the engine. This
allows the turbocharger to slow
down while keeping the bearings
lubricated.
If the Vehicle Has Not Been Used
for a Long Period
If a diesel vehicle has been
standing for an extended period of
time, the turbocharger bearings
should be pre-lubricated prior to
starting. See your authorized dealer
for more detailed information.
Before using a vehicle that has not
been driven for a long period, check
the engine and transmission for oil
leakage, and make sure the oil is at the required levels. If there is
insufficient oil, it will not adequately
reach and lubricate components,
and a breakdown will result.
Start the engine and allow it to idle
for at least five minutes. Check for
abnormal noises.
For instructions on warming up the
engine, refer to
“Starting the Engine”
previously in this section.
If one year has passed since the
diesel exhaust fluid (DEF) in the
DEF tank was added, the DEF in
the tank should be replaced. Be
careful not to inhale the ammonia
odor when replacing the DEF. Also,
please contact your nearest dealer
about the replacement work.
Operating Temperature
Recommendations for Warming
Up the Engine
The engine is sufficiently warmed
up when the needle of the engine
coolant temperature gauge starts
to move.

4. Press the cruise control mainswitch to set it to ON. At this
time, the operation indicating
light will turn to green.
5. Turn and hold the cruise control set switch in the SET
position. After approximately
3 seconds the cruise control
set indicator light will begin to
flash slowly and the engine idle
will increase to 1,200 r/min.
Canceling High Idle Mode
Any of the following actions will
cancel high idle mode.
. The cruise control main switch is
set to OFF.
. The brake pedal is pressed.
. The parking brake is released.
. The selector lever is moved from
P (Park) or N (Neutral) position.
. The accelerator pedal is
pressed, accelerating the engine
beyond the engine speed
threshold. The cruise set indicator light will
stop flashing and the engine speed
will return to normal.
Engine Checks Before
Operating
Checks Before Operating
Allow the engine to warm up before
placing the engine under heavy load
driving. While the engine is warming
up under light load, the following
checks should be made:
1. Observe the red engine oil pressure warning light. The
light should go out when the
engine is running. If it stays on,
shut the engine off and find the
cause.
2. Look at the engine coolant temperature gauge. If the
gauge reaches the H (HOT)
area, stop the engine and find
the cause of the overheating.
3. Check that the battery warning light has gone out. The light
should go off and stay off at
normal idle speeds. If the light does not go out or comes on
during normal operation, have
the charging system checked.
4. Check that the brake low vacuum warning light is out
and that the vacuum buzzer is
not sounding. It is normal for
the warning buzzer to sound
for a few seconds after the
engine starts. If the light and
buzzer remain on, do not drive
the vehicle until the cause has
been found and corrected.
5. Look at the brake system warning light. It should be out
when the parking brake is
released and the engine is
running. If it stays on, it could
mean that the brake fluid level
is low. Check the brake fluid
reservoir. This condition must
be corrected before moving the
vehicle.
