WARNING

■ Replacing light bulbs

● Turn off the lights. Do not attempt to replace the bulb immediately after

turning off the lights.

The bulbs become very hot and may cause burns.

●Do not touch the glass portion of the light bulb with bare hands. When it is

unavoidable to hold the glass portion, use and hold with a clean dry cloth

to avoid getting moisture and oils on the bulb.

Also, if the bulb is scratched or dropped, it may blow out or crack.

●Fully install light bulbs and any parts used to secure them. Failure to do so

may result in heat damage, fire, or water entering the headlight unit. This

may damage the headlights or cause condensation to build up on the lens.

●Do not attempt to repair or disassemble light bulbs, connectors, electric

circuits or component parts.

Doing so may result in death or serious injury due to electric shock.

■ To prevent damage or fire

● Make sure bulbs are fully seated and locked.

●Check the wattage of the bulb before installing to prevent heat damage.

NOTICE

■ When replacing the outer foot lights

If the front window is stopping you from conducting the replace operation

properly, open the window on the side you are working on to allow you

enough space to work. Continuing the operation without giving yourself

enough space to work could lead you to scratch the vehicle.

8-1. Essential information

555

If the vehicle is submerged or water on the

road is rising

This vehicle is not designed to be able to drive on roads that are

deeply flooded with water. Do not drive on roads where the

roads may be submerged or the water may be rising. It is dan-

gerous to remain in the vehicle, if it anticipated that the vehicle

will be flooded or set a drift. Remain calm and follow the follow-

ing.

● If the door can be opened, open the door and exit the vehicle.

● If the door can not be opened, open the window using the power

window switch and ensure an escape route.

● If the window can be opened, exit the vehicle through the window.

● If the door and window cannot be opened due to the rising water,

remain calm, wait until the water level inside the vehicle rises to the

point that the water pressure inside of the vehicle equals the water

pressure outside of the vehicle and then open the door after waiting

for the rising water to enter the vehicle, and exit the vehicle. When

the outside water level exceeds half the height of the door, the door

cannot be opened from the inside due to water pressure.

■ Water level exceeds the floor

When the water level exceeds the floor and time has passed, the electrical

equipment will get damaged, the power windows will not operate, the engine

stop, and the vehicle may not be able to get moving.

■ Using an emergency escape hammer*

Laminated glass is used in the windshield on this vehicle.

Laminated glass cannot be shattered with an emergency hammer*.

Tempered glass is used in the windows on this vehicle.

temporarily towed using cables or chains secured to the emergency

towing hooks. This should only be attempted on hard surfaced roads

for at most 80 km (50 miles) at under 30 km/h (18 mph).

A driver must be in the vehicle to steer and operate the brakes. The

vehicle’s wheels, drive train, axles, steering and brakes must be in

good condition.

Emergency towing procedure

Securely attach cables or

chains to the towing hooks.

Take care not to damage the vehi-

cle body.

Enter the vehicle being towed and start the engine.

If the engine does not start, turn the engine switch to the “ON” position

(vehicles without smart entry & start system) or IGNITION ON mode (vehi-

cles with smart entry & start system).

Vehicles with Stop & Start system:

Before towing the vehicle, turn the engine switch to the “LOCK” position

(vehicles without smart entry & start system) or off (vehicles with smart

entry & start system) once, and then start the engine.

8-2. Steps to take in an emergency

■While towing

If the engine is not running, the power assist for the brakes and steering will

not function, making steering and braking more difficult.

WARNING

Observe the following precautions.

Failure to do so may result in death or serious injury.

■ When towing the vehicle

Pre Runner (2WD models): Be sure to

transport the vehicle with all four wheels

raised off the ground. If the vehicle is

towed with the tires contacting the

ground, the drivetrain and related parts

may be damaged or an accident may

occur due to a change in direction of the

vehicle.

4WD models: Be sure to transport the

vehicle with all four wheels raised off the

ground. If the vehicle is towed with the

tires contacting the ground, the drivetrain

and related parts may be damaged, and

the vehicle may fly off the truck.

■ While towing

●When towing using cables or chains, avoid sudden starts, etc. which place

excessive stress on the towing hooks, cables or chains. The towing hooks,

cables or chains may become damaged, broken debris may hit people,

and cause serious damage.

● Vehicles without smart entry & start system or vehicles with manual trans-

mission: Do not turn the engine switch to the “LOCK” position (vehicles

without smart entry & start system) or off (vehicles with smart entry & start

system).

There is a possibility that the steering wheel is locked and cannot be oper-

ated.

8-2. Steps to take in an emergency

561

NOTICE

■ To prevent damage to the vehicle when towing using a wheel-lift type

truck

●Do not tow the vehicle from the rear when the engine switch is in the

“LOCK” position or the key is removed (vehicles without smart entry & start

system) or the engine switch is turned to off (vehicles with smart entry &

start system). The steering lock mechanism (if equipped) is not strong

enough to hold the front wheels straight.

● When raising the vehicle, ensure adequate ground clearance for towing at

the opposite end of the raised vehicle. Without adequate clearance, the

vehicle could be damaged while being towed.

■ To prevent damage to the vehicle when towing with a sling-type truck

Do not tow with a sling-type truck, either from the front or rear.

■ To prevent damage to the vehicle during emergency towing

Do not secure cables or chains to the suspension components.

■ When towing a vehicle equipped with a Stop & Start system (if

equipped)

If it is necessary to tow the vehicle with all 4 wheels on the ground, perform

the following procedure before towing the vehicle, in order to protect the

system.

Turn the engine switch to the “LOCK” position (vehicles without smart entry

& start system) or off (vehicles with smart entry & start system) and then

start the engine or turn the engine switch to the “ON” position (vehicles with-

out smart entry & start system) or IGNITION ON mode (vehicles with smart

entry & start system).

Fuel pump shut off system (gasoline engine only)

To minimize the risk of fuel leakage when the engine stalls or

when an airbag inflates upon collision, the fuel pump shut off

system stops the supply of fuel to the engine.

Follow the procedure below to restart the engine after the system is

activated.

Turn the engine switch to the “ACC” or “LOCK” position (vehicles

without smart entry & start system) or ACCESSORY mode or off

(vehicles with smart entry & start system).
