If your vehicle needs to be towed

If towing is necessary, we recommend 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/provincial and
local laws.
If towing your vehicle with a wheel-lift type truck from the front, the vehicle’s
rear wheels and axles must be in good conditions. (



P. 659, 661)

If they are damaged, use a towing dolly or flatbed truck.

WARNING

Observe the following precautions.

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

■

When towing the vehicle

■

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 damaged, broken debris may hit people, and cause serious damage.

●

Do not turn the power switch off.

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

■

Installing towing eyelet to the vehicle

Make sure that towing eyelet is installed securely. If not securely installed, towing eyelet

may come loose during towing.

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 electric-

ity generated by the operation of the motor

may cause a fire to occur depending on the

nature of the damage or malfunction.

660

8-2. Steps to take in an emergency

In the following situations, it is not possible to be towed by another vehicle using
cables or chains, as the front wheels may be locked due to the parking lock. Con-

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 adequate ground clearance for towing at the oppo-

site end of the raised vehicle. Without adequate clearance, the vehicle could be dam-

aged while being towed.

may cause the warning light to flash and the warning buzzer to sound even if a passen-

ger is not sitting in the seat.

●

If a cushion is placed on the seat, the sensor may not detect a passenger, and the warn-

ing light may not operate properly.

■

Electric power steering system warning light (warning buzzer)

When the 12-volt battery charge becomes insufficient or the voltage temporarily drops,

the electric power steering system warning light may come on and the warning buzzer

may sound.

■

If the malfunction indicator lamp comes on while driving

The malfunction indicator lamp will come on if the fuel tank becomes completely empty.

If the fuel tank is empty, refuel the vehicle immediately. The malfunction indicator lamp

If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered sufficiently.

●

Check the tire inflation pressure and adjust to the appropriate level.

●

If the warning light does not go out even after several minutes, check that the tire infla-

tion pressure is at the specified level and carry out initialization. (

If the tire pressure warning light comes on

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

vehicle control and result in death or serious injury.

●

Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure

immediately.

●

Vehicles with a spare tire: If the tire pressure warning light comes on even after tire

inflation pressure adjustment, it is probable that you have a flat tire. Check the tires. If

a tire is flat, change it with the spare tire and have the flat tire repaired by the nearest

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

●

Vehicles with an emergency tire puncture repair kit: If the tire pressure warning light

comes on even after tire inflation pressure adjustment, it is probable that you have a

flat tire. Check the tires. If a tire is flat, repair the flat tire by using emergency tire punc-

ture repair kit.

●

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

control of the steering wheel or the brakes.
