When driving
HILUX_OM_OM0K134E_(EE)
CAUTION
During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 598
Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 167)
Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents,
resulting in death or serious injury.
Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or serious injury.
On vehicles with manual transmission, do not operate the clutch halfway
for a long period of time unless it is necessary. Doing so could not only
speed up clutch wear, but could also damage the clutch or even cause a
fatal accident such as vehicle fire.

CAUTION
When the vehicle is stopped
Do not race the engine.
If the vehicle is in any gear other than P (vehicles with automatic transmis-
sion only) or N, the vehicle may accelerate suddenly and unexpectedly,
causing an accident.
Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
On vehicles with automatic transmission, in order to prevent accidents due
to the vehicle rolling away, always keep depressing the brake pedal while
the engine is running, and apply the parking brake as necessary.
If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

158 2-1. Driving procedures
HILUX_OM_OM0K134E_(EE)
CAUTION
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever
or depress the accelerator pedal, this could cause an accident or fire due to
engine overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to
death or a serious health hazard.
When braking
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
If the power brake assist function does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking. In this
case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase.
Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
The brake system consists of 2 individual hydraulic systems: If one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase.
If this happens, do not continue to drive the vehicle. Have your brakes
fixed immediately.

CAUTION
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Caution when driving
Do not turn the engine switch to the “LOCK” position while driving.
If in an emergency, you must turn the engine off while the vehicle is moving,
turn the engine switch only to the “ACC” position to stop the engine. An acci-
dent may result if the engine is stopped while driving.
NOTICE
To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long periods
of time without the engine running.
When starting the engine
Do not crank the engine for more than 30 seconds at a time. This may
overheat the starter and wiring system.
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

Vehicles with optitron type meter
The engine switch is in the “ON” position.
The odometer and trip meter display illuminate when
The engine switch is in the “ON” position.
The brightness of the instrument panel lights
When the headlight switch is turned to on, the brightness will be reduced
slightly unless the control dial is turned fully clockwise.
When disconnecting and reconnecting battery terminals
The trip meter data will be reset.
NOTICE
To prevent damage to the engine and its components
Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 592)

248 2-5. Driving information
HILUX_OM_OM0K134E_(EE)If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If the
engine coolant temperature gauge indicates that the engine is
overheating, turn the air conditioning off immediately, leave the
road and stop the vehicle in a safe place. (P. 592)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever to P
for automatic transmissions, and 1 or R for manual transmissions.
CAUTION
Follow all the precautions described in this section. Failure to do so could
cause an accident resulting in death or serious injury.
Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded.
(P. 240)
Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while
descending steep or long down hill grades.
Operation of the brake pedal
Do not hold the brake pedal depressed often or for long periods of time.
Doing so may result in the brake overheating or reduce braking effects.
