7-2.Steps to take in an emergency

If your vehicle needs to be
towed

If towing is necessary, we recom-
mend having your vehicle towed by
any authorized Lexus retailer or
Lexus authorized repairer, or any
reliable repairer 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.

Q

When towing the vehicle

LC500: Be sure to transport the vehicle

with all four wheels raised off the ground.

If the vehicle is towed with the tires con-

tacting the ground, the drivetrain and

related parts may be damaged or an

accident may occur due to a change in

direction of the vehicle.

LC500h: Be sure to transport the vehi-

cle with all four wheels raised off the

ground. If the vehicle is towed with the

tires contacting the ground, the drive-

train and related parts may be damaged,

an accident may occur due to a change

in direction of the vehicle or electricity

generated by the operation of the motor

may cause a fire to occur depending on

the nature of the damage or malfunction.

Q

While towing

O

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.

O

Do not turn the engine switch <power

switch> off.

This may lead to an accident as the

rear wheels will be locked by the park-

ing lock. Also, there is a possibility that

the steering wheel is locked and can-

not be operated.

Q

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.

436

7-2. Steps to take in an emergency

In the following situations, it is not pos-
sible to be towed by another vehicle
using cables or chains, as the rear
wheels may be locked due to the park-
ing lock. Contact any authorized Lexus

NOTICE

Q

To prevent damage to the vehicle

when towing using a wheel-lift type

truck

O

Do not tow the vehicle from the rear

when the engine switch <power

switch> is off. The steering lock mecha-

nism is not strong enough to hold the

front wheels straight.

O

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.

In order to suppress vehicle movement
during transportation, set the parking
brake and turn the engine switch
<power switch> off.

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 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.

WARNING

Q

If both the ABS and the brake system warning lights remain on

Stop your vehicle in a safe place immediately and contact any authorized Lexus retailer

or Lexus authorized repairer, or any reliable repairer. The vehicle will become extremely

unstable during braking, and the ABS system may fail, which could cause an accident

resulting in death or serious injury.

Q

When the electric power steering system warning light comes on

When the light comes on yellow, the assist to the power steering is restricted. When the

light comes on red, the assist to the power steering is lost and handling operations of the

steering wheel become extremely heavy. When steering wheel operations are heavier

than usual, grip the steering wheel firmly and operate it using more force than usual.

Q

If the tire pressure warning light comes on

Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-

cle control and result in death or serious injury.

O

Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 80

km/h (50 mph).

O

Check and adjust the tire inflation pressure immediately.

O

If the tire pressure warning light comes on even after tire inflation pressure adjustment,

it is probable that you have a flat tire. Have the flat tire replaced by nearest authorized

Lexus retailer or Lexus authorized repairer, or any reliable repairer.

O

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose

control of the steering wheel or the brakes.

Q

If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.
