■ After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacing. ( P. 423)
● If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■ If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.

5-1. Essential information
Towing with a wheel-lift type truck from the rear
Automatic transmission: Use a
towing dolly under the front
wheels.
Manual transmissions: We rec-
ommend to use a towing dolly
under the front wheels.
When not using a towing dolly,
turn the engine switch to the
“ACC” position and shift the shift
lever to N.
Using a flat bed truckIf you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45.
Do not overly tighten the tie
downs or the vehicle may be
damaged.
NOTICE
■ To prevent causing serious dama ge to the transmission
(automatic transmission)
Never tow this vehicle from the rear with the front wheels on the ground.
■ To prevent damaging the vehicle (manual transmission)
Do not tow the vehicle when the engine switch is in the “LOCK” position or
key removed.
The steering lock mechanism is not strong enough to hold the front wheel
straight.

5-1. Essential information
Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.Vehicles with smart key systemTurn the “ENGINE START STOP” switch OFF.
Restart the engine.
Vehicles without smart key system Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked on to the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or an air-
bag inflates upon collision, the fu el pump shut off system stops sup-
plying fuel to the engine.
