2012 TOYOTA HILUX overheating

158 2-1. Driving procedures
HILUX_EE (OM0K132E)
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.

HILUX_EE (OM0K132E)
Parking brake
Usage in winter time
See “Winter driving tips” for parking brake usage in winter time. (P. 234)
NOTICE
Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components
overheating, which may affect braking performance and increase brake
wear.
To set the parking brake,
fully pull the parking brake
lever while depressing the
brake pedal.
At this time, the brake system
warning light will come on.
To release the parking
brake, slightly raise the
lever and lower it in com-
pletely while pressing the
button.
At this time, the brake system
warning light will go off.

When driving
HILUX_EE (OM0K132E)
The meters and 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. 584)

When driving
HILUX_EE (OM0K132E)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. 584)
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. 239)
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.

CAUTION
Burns
Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE
To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
To prevent battery discharge
Turn the seat heaters off when the engine is not running.

585 5-2. Steps to take in an emergency
When trouble arises
HILUX_EE (OM0K132E)
Overheating
If you observe the following, your vehicle may be overheating:
The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
Steam comes out from under the hood.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. (P. 606)
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional as
soon as possible.
