When a malfunction occurs during charging

The indicators on the CCID (Charging Circuit Interrupting Device) use a
combination of different statuses (not illuminated, illuminated or flashing) to
inform the user of internal malfunctions.

When the error warning indicator is illuminated or flashing, temporarily remove the plug
from the outlet and then reconnect it to check if the error indicator turns off.
If the error warning indicator turns off, charging is now possible. If it does not turn off,
perform the correction procedure in the following chart.

Towing with a tow truck

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 adequate ground clearance for towing at the oppo-
site end of the raised vehicle. Without adequate clearance, the vehicle could be
damaged while being towed.

Towing with a tow truck

If towing is necessary, we recommend having your vehicle towed by your Lexus
dealer or a 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.

WARNING

Be sure to transport the vehicle with all four wheels
raised off the ground. If the vehicle is towed with the
tires contacting the ground, the drivetrain or related
parts may be damaged, the vehicle may fly off the
truck, or electricity generated by the operation of the
motor may cause a fire to occur depending on the
nature of the damage or malfunction.

towed using cables or chains secured to the emergency towing eyelets. 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.

chains to the suspension components.

Enter the vehicle being towed and start the hybrid system.

If the hybrid system does not start, turn the power switch to ON.

INFORMATION

■

While towing

If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.

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

Shift the shift position to N and release the parking brake.

Turn auto mode of the parking brake off.

provide traction.

Restart the hybrid system.

Shift the shift position to D or R and release the parking brake. Then, while
exercising caution, depress the accelerator pedal.

WARNING

●

When shifting the shift lever, do not shift it with the accelerator pedal depressed.
Doing so may lead to unexpected rapid acceleration of the vehicle that may cause
an accident.

●

If you choose to push the vehicle back and forth to free it, make sure the surround-
ing area is clear to avoid striking other vehicles, objects or people.
The vehicle may also lunge forward or lunge back suddenly as it becomes free.
Use extreme caution.

NOTICE

Avoid spinning the front wheels and depressing the accelerator pedal more than
necessary.
Doing so may damage the hybrid transmission and other components.

If it is difficult to free the vehicle, press the

switch and turn the TRAC off.

If the vehicle remains stuck even after these procedures are performed, the vehicle
may require towing to be freed.
