■After a fuse is replaced

●If the lights do not turn on even after the fuse has been replaced, a bulb

may need replacement. (→P. 422)

●If the replaced fuse blows again, have the vehicle inspected by your

Toyota dealer.

■If there is an overload in a circuit

The fuses are designed to blow, protecting the wiring harness from damage.

■When replacing light bulbs

Toyota recommends that you use genuine Toyota products designed for this vehicle. Because certain bulbs are connected to circuits designed to prevent overload, non-genuine parts or parts not designed for this vehicle may be unusable.

CAUTION

■To prevent system breakdowns and vehicle fire

Observe the following precautions. Failure to do so may cause damage to the vehicle, and possibly a fire or injury. ●Never use a fuse of a higher amperage rating than that indicated, or use

any other object in place of a fuse.

●Always use a genuine Toyota fuse or equivalent.

Never replace a fuse with a wire, even as a temporary fix.

●Do not modify the fuses or fuse boxes. ■Fuse box near the power control unit

Never check or replace the fuses as there are high voltage parts and wiring near the fuse box. Doing so may cause electric shock, resulting in death or serious injury.

■LED lights

The headlight low beams (LED type), stop lights, tail lights, rear side marker lights and high mounted stoplight consist of a number of LEDs. If any of the LEDs burn out, take your vehicle to your Toyota dealer to have the light replaced.

■Condensation build-up on the inside of the lens

Contact your Toyota dealer for more information in the following situations. Temporary condensation build-up on the inside of the headlight lens does not indicate a malfunction. ●Large drops of water have built up on the inside of the lens. ●Water has built up inside the headlight.

CAUTION

■Replacing light bulbs

●Be sure to stop the hybrid system and 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. Hold the

bulb by the plastic or metal portion. 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.

■To prevent damage or fire

Make sure bulbs are fully seated and locked.

5-1. Essential information If your vehicle needs to be towed

If towing is necessary, we recommend having your vehicle towed by your Toyota dealer or a commercial towing service, using a lift-type truck or flat bed truck. Use a safety chain system for all towing, and abide by all state/pro- vincial and local laws.

Before towing

The following may indicate a problem with your hybrid transmission. Contact your Toyota dealer before towing. ● The hybrid system is operating but the vehicle will not move. ● The vehicle makes an abnormal sound. If there is a malfunction in the P position control system, the smart key system or the immobilizer system, or if the 12-volt battery is dis- charged, the vehicle cannot be towed with the front wheels on the ground, as the front wheels may be locked. In this case, transport the vehicle with both front wheels or all four wheels lifted.

439

PRIUS v_OM_OM47820U_(U)

5-1. Essential information

Emergency towing

If a tow truck is not available in an emergency, your vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet(s). This should only be attempted on hard surfaced roads for short distances at under 18 mph (30 km/h). 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.

CAUTION

■Caution while towing

●Use extreme caution when towing the vehicle.

Avoid sudden starts or erratic driving maneuvers which place excessive stress on the emergency towing eyelets and the cables or chains. Always be cautious of the surroundings and other vehicles while towing.

●Do not turn the “POWER” switch off.

This may lead to an accident as the front wheels will be locked by the parking lock.

●If the hybrid system is off, the power assist for the brakes and steering will

not function, making steering and braking more difficult.

■Installing towing eyelets to the vehicle

Make sure that towing eyelets are installed securely. If not securely installed, towing eyelets may come loose during towing. This may lead to accidents that cause serious injury or even death.

NOTICE

■To prevent damaging the vehicle

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 causing serious damage to the hybrid transmission when

towing using a wheel-lift type truck Never tow this vehicle from the rear with the front wheels on the ground.

■To prevent body damage when towing with a sling-type truck

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

■To prevent causing serious damage to the hybrid transmission in

emergency towing Never tow a vehicle from the rear with four wheels on the ground. This may cause serious damage to the hybrid transmission.
