Scheduled maintenance of the air

intake vent is necessary when

In some situations such as when the vehicle

is used frequently or in heavy traffic or dusty

areas, the air intake vent may need to be

cleaned more regularly. For details, refer to

“Lexus Service Booklet” or “Lexus War-

ranty Booklet”.

Cleaning the air intake vent

Dust in the air intake vent may interfere

with the cooling of the hybrid battery

(traction battery). If charging/discharg-

ing of the hybrid battery (traction battery)

becomes limited, the distance that the

vehicle can be driven using the electric

motor (traction motor) may be reduced

and the fuel economy may be reduced.

Inspect and clean the air intake vent peri-

odically.

Improper handling of the air intake vent

cover and filter may result in damage to

them. If you have any concerns about

cleaning the filter, contact any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

If “Maintenance required for Traction

battery cooling parts See owner’s man-

ual” is displayed on the multi-informa-

tion display

If this warning message is displayed on

the multi-information display, remove the

air intake vent cover and clean the filter.

(



P.385)

After cleaning the air intake vent, start

the hybrid system and check that the

warning message is no longer displayed.

After the hybrid system is started, it may

be necessary to drive the vehicle up to

approximately 20 minutes before the

warning message disappears. If the warn-

ing message does not disappear after

driving for appropriately 20 minutes,

have the vehicle inspected by any autho-

rized Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

WARNING

When cleaning the air intake vent

Do not use water or other liquids to

clean the air intake vent. If water is

applied to the hybrid battery (traction

battery) or other components, a mal-

function or fire may occur.

Before cleaning the air intake vent,

make sure to turn the power switch off

to stop the hybrid system.

When removing the air intake vent

cover

Do not touch the service plug located

near the air intake vent. (

6-3. Do-it-yourself maintenance

NOTICE

When cleaning the air intake vent

When cleaning the air intake vent, make

sure to only use a vacuum to suck out

dust and clogs. If a compressed air blow

gun, etc. is used to blow out dust and

clogs, the dust or clogs may be pushed

into the air intake vent, which may affect

the performance of the hybrid battery

(traction battery) and cause a malfunc-

tion.

To prevent damage to the vehicle

Do not allow water or foreign matter

to enter the air intake vent when the

cover is removed.

Carefully handle the removed filter so

that it will not be damaged.

If the filter is damaged, have it

replaced with a new filter by any

authorized Lexus retailer or Lexus

authorized repairer, or any reliable

repairer.

Make sure to reinstall the filter and

cover to their original positions after

cleaning.

Do not install anything to the air intake

vent other than the exclusive filter for

this vehicle or use the vehicle without

the filter installed.

If “Maintenance required for Trac-

tion battery cooling parts See

owner’s manual” is displayed on the

multi-information display

If the vehicle is continuously driven with

the warning message (indicating that

charging/discharging of the hybrid bat-

tery (traction battery) may become lim-

ited) displayed, the hybrid battery

(traction battery) may malfunction. If the

warning message is displayed, clean the

air intake vent immediately.

To prevent battery explosion or leak-

age of flammable liquid or gas

Replace the battery with a new battery

of the same type. If a wrong type of

battery is used, it may explode.

Do not expose batteries to extremely

low pressure due to high altitude or

extremely high temperatures.

When using a flat-bed truck to trans-
port the vehicle, use tire strapping
belts. Refer to the owner’s manual of
the flat-bed truck for the tire strapping
method.
In order to suppress vehicle movement
during transportation, set the parking
brake and turn the 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-
let. 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

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.

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.
