AM Transmissions
Fading - AM broadcasts are
reflected by the upper atmosphere,
especially at night. These reflected
signals can interfere with those
received directly from the radio
station, causing the radio station to
sound alternately strong and weak.
Station interference - When a
reflected signal and a signal
received directly from a radio station
are very nearly the same frequency,
they can interfere with each other,
making it difficult to hear the
broadcast.
Static - AM is easily affected by
external sources of electrical noise,
such as high tension power lines,
lightning, or electrical motors. This
results in static.

Warning (Continued)
should overheat, as indicated by
the engine coolant temperature
gauge, immediate action is
required to correct the condition.
Continued operation of the
engine, even for a short time, may
result in a fire. Do not engage the
exhaust brake while the engine is
idling as this may cause engine
overheating.
The diesel particulate filter (DPF)
may automatically start
regeneration when the vehicle is
stopped and parked with the
engine running. To prevent a fire,
make sure there is no flammable
material near the muffler, DPF,
and exhaust pipe. Be careful not
to get burned by hot exhaust
gases.
You and others could be seriously
injured.Do Not Forget to Release the
Parking Brake
Pulling away with the parking brake
still applied can damage the brake
system.
Before pulling away, make sure the
parking brake is not set by checking
that the parking brake indicator light
is not on.
Be Sure to Have the Engine
Running When the Vehicle is
Moving
{Warning
When the engine is not running,
the power steering system does
not work so the steering wheel is
hard to turn. Also, the brake
booster does not work so there is
little braking ability. If you coast
down a slope without the engine
running, you would not be able to
properly control the vehicle and
could have a crash.
Parking, or Leaving
Driver
’s Seat
{Danger
It can be dangerous to get out of
your vehicle if the selector lever is
not fully in "P" (Park) or the
parking brake is not applied all
the way. Your vehicle can roll or
move suddenly.
To be sure your vehicle will not
move, even when you are parking
on level ground, follow the steps
below. (If you have to park on a
hill, also turn your front wheels so
the vehicle will roll away from
traffic.)
You and others could be seriously
injured or killed.
1. Hold the regular brake pedal down with your right foot and
apply the parking brake all the
way before shifting the
transmission. Follow the
Parking Brake instructions in
this manual for your vehicle.

Emergencies (Disabled
Vehicle)
When the Vehicle
Breaks Down
When the Vehicle Stops While
Driving
The brake booster will no longer
operate and brake effectiveness will
be reduced. If the engine cannot be
started, promptly have the vehicle
inspected and repaired.
If the engine stopped because the
vehicle ran out of fuel while driving,
refueling alone will not be enough to
restart the engine. Bleed the fuel
system after refueling the vehicle.
When the Fuel Tank is Empty
SeeRunning Out of Fuel 0224.
When the Engine Stalls and
Cannot Be Restarted
Move the selector lever to the "N"
position and push the vehicle to a
safe place.
{Warning
Vehicle operations will change, so
stop the vehicle in a safe place
with the following in mind.
The power steering system will
not work so the steering wheel
will be hard to turn. It will require
more strength than during normal
operation.
As the brake booster will no
longer be functional, brake
effectiveness will be greatly
reduced. Be sure to apply more
pressure than usual to the brake
pedal.
If the power assist steering
system goes out because the
engine has stopped or the assist
system has malfunctioned, the
vehicle can still be steered.
However, much greater effort is
needed, especially in sharp turns
or at low speeds.
You and others could be seriously
injured. When the Vehicle Breaks Down
During Driving
1. Use the hazard warning flasher any time to warn other drivers,
day or night, and pull the
vehicle immediately over to a
safe place that does not
impede traffic (shoulder). Place
triangle reflectors to alert other
traffic to the presence of your
vehicle.
2. If the vehicle can be exited safely, have the other
passengers get out and wait in
a safe place.
3. If the vehicle can be exited safely, walk to a safe place and
take appropriate measures by
using the closest
telephone, etc.
See Hazard Warning Flashers 082.

Starting and

New Vehicle Break-In
Good vehicle care begins with
proper break-in. While every new
vehicle goes through rigid factory
and dealer inspection and tests
before delivery, the care you give
your vehicle during the initial
break-in period can pay off in longer
life, better performance and more
economical operation.
It is therefore always recommended
that during the initial 1 000 km
(600 mile) break-in period, the
following few simple precautions are
carefully observed.
Follow the recommendations listed
below:
.Warm up the engine by driving
easily for the first few minutes
before placing it under load.
. Do not drive for extended
periods at any one constant
speed, either fast or slow, during
the first 800 km (500 miles). .
Use the correct gear to maintain
the desired road speed without
lugging the engine.
. Avoid racing the engine,
full-throttle starts and aggressive
application of brakes when
stopping.
. Keep tires properly inflated for
the load carried.
. Check lubricant levels in the
engine and transmission weekly.
. Keep speeds below 80 km/h
(50 MPH) for the first 800 km
(500 miles).
. Use the lowest gear ratio
available when starting a loaded
vehicle and when climbing
slopes to avoid lugging the
engine.
. It is recommended that the
engine speed is restricted to
2,300 r/min.

158 Driving and Operating
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.
