After a fuse is replaced

●

When installing the lid, make sure that the

●

If the replaced fuse blows again, have the

vehicle inspected by your Lexus 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

Lexus recommends that you use genuine

Lexus products designed for this vehicle.

Because certain bulbs are connected to cir-

cuits designed to prevent overload, non-

genuine parts or parts not designed for this

vehicle may be unusable.

7-2.Steps to take in an emergency

The following may indicate a problem
with your hybrid transmission. Contact
your Lexus dealer or commercial tow-
ing service before towing.
 The hybrid system warning message

If your vehicle needs to be
towed

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

WARNING

Observe the following precautions.

Failure to do so may result in death or

serious injury.

■

When towing the vehicle

Be sure to transport the vehicle with the

front wheels raised or with all four wheels

raised off the ground. If the vehicle is

towed with the front wheels contacting

the ground, the drivetrain and related

parts may be damaged or electricity

generated by the operation of the motor

may cause a fire to occur depending on

the nature of the damage or malfunction.

■

While towing

●

When towing using cables or chains,

avoid sudden starts, etc. which place

excessive stress on the towing eyelets,

cables or chains. The towing eyelets,

cables or chains may become dam-

aged, broken debris may hit people,

and cause serious damage.

●

Do not turn the power switch off.

There is a possibility that the steering

wheel is locked and cannot be oper-

ated.

■

Installing towing eyelets to the vehi-

cle

Make sure that towing eyelets are

installed securely.

If not securely installed, towing eyelets

may come loose during towing.

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 power switch is off. The

steering lock mechanism is not strong

enough to hold the front wheels

straight.

●

When raising the vehicle, ensure ade-

quate ground clearance for towing at

the opposite end of the raised vehicle.

Without adequate clearance, the vehi-

cle 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

If your vehicle is transported by a flat-
bed truck, it should be tied down at the
locations shown in the illustration.

If 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.

If a tow truck is not available in an
emergency, your vehicle may be tem-
porarily towed using cables or chains
secured to the emergency towing eye-
lets. 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.

vehicle, the towing eyelet must be
installed to your vehicle. Install the tow-
ing eyelet using the following proce-
dure.

Take out the towing eyelet.
(

P.373)

Remove the eyelet cover using a
flathead screwdriver.

To protect the bodywork, place a rag

between the screwdriver and the vehicle

body as shown in the illustration.

Insert the towing eyelet into the
hole and tighten partially by hand.

Tighten down the towing eyelet
securely using a wheel nut wrench
or hard metal bar.

Securely attach cables or chains to
the towing eyelet.

Take care not to damage the vehicle body.

Enter the vehicle being towed and
start the hybrid system.
