Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may
occur and result in an accident causing death or serious injury:
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and cause air
leakage, which could result in an accident. If the caps are lost, replace them as
soon as possible.

Maintenance and care
If the filter is dirty, clean by blow-
ing compressed air through the fil-
ter from the underside.
Hold the air gun 5 cm (2 in.)
from the filter and blow for
approximately 2 minutes at 500
kPa (5.0 kgf/cm
2 or bar, 72 psi).
If an air gun is not available,
have the filter cleaned by any
authorized Lexus dealer or
repairer, or another duly qualified
and equipped professional.
Checking interval
Inspect, clean and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement may
be required. (For scheduled maintenance information, please refer to the “Lexus
Service Booklet” or “Lexus Warranty Booklet”.)
If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
Cleaning method
NOTICE
To prevent damage to the system
When using the air conditioning system, make sure that a filter is always
installed.
When cleaning the filter, do not clean with water.

If your vehicle needs to be towed
In the following situations, it is not possible to be towed by another vehi-
cle using cable or chain, as the front wheels may be locked due to the
parking lock. Contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional or a commercial towing service.
There is a malfunction in the P position control system. (P. 581)
There is a malfunction in the immobilizer system. (P. 87)
There is a malfunction in the smart entry & start system. (P. 622)
The 12-volt battery is discharged. (P. 624)
If towing is necessary, we recommend having your vehicle towed by any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional or a commercial towing service, using a lift-type
truck or flat bed 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. 563,
566)
If they are damaged, use a towing dolly or flatbed truck.

When trouble arises
If you think something is wrong
Fluid leaks under the vehicle
(Water dripping from the air conditioning after use is normal.)
Flat-looking tires or uneven tire wear
High coolant temperature warning light flashes or comes on
Changes in exhaust sound
Excessive tire squeal when cornering
Strange noises related to the suspension system
Pinging or other noises related to the hybrid system
Engine missing, stumbling or running roughly
Appreciable loss of power
Vehicle pulls heavily to one side when braking
Vehicle pulls heavily to one side when driving on a level road
Loss of brake effectiveness, spongy feeling, pedal almost touches the
floor
If you notice any of the following symptoms, your vehicle probably

When trouble arises
When a tire is replaced with a spare tire (vehicles with a compact spare tire and
the tire pressure warning system)
The compact spare tire is not equipped with a tire pressure warning valve and
transmitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire has been replaced with the spare tire. Replace the spare tire
with the repaired tire and adjust the tire inflation pressure. The tire pressure
warning light will go off after a few minutes.
Conditions that the tire pressure warning system may not function properly (vehi-
cles with the tire pressure warning system)
P. 514
If the tire pressure warning light frequently comes on after blinking for 1 minute
(vehicles with the tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1 minute
when the power switch is turned to ON mode, have it checked by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location or
audio sound.
WA R N I N G
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
dealer or repairer, or another duly qualified and equipped professional. 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.
When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly
and operate using more force than usual.

When fixing the flat tire
Stop your vehicle in a safe and flat area.
Connect the valve and hose securely with the tire installed on the vehicle.
If the hose is not properly connected to the valve, air leakage may occur or
sealant may be sprayed out.
If the hose comes off the valve while inflating the tire, there is a risk that the
hose will move abruptly due to air pressure.
After inflation of the tire has completed, the sealant may splatter when the
hose is disconnected or some air is let out of the tire.
Keep back from the tire while it is being repaired, as there is a chance of it
bursting while the repair operation is being performed. If you notice any
cracks or deformation of the tire, turn off the compressor switch and stop the
repair operation immediately.
The kit may overheat if operated for a long period of time. Do not operate the
compressor continuously for more than 10 minutes.
Parts of the kit become hot during operation. Be careful handling the kit
during and after operation.
Do not attach the vehicle speed warning sticker to an area other than the one
indicated. If the sticker is attached to an area where an SRS airbag is located,
such as the pad of the steering wheel, it may prevent the SRS air bag from
operating properly.
Driving to spread the liquid sealant evenly
Drive the vehicle carefully at a low speed. Be especially careful when turning
and cornering.
If the vehicle does not drive straight or you feel a pull through the steering
wheel, stop the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm
2 or
bar, 19 psi) or below, this may indicate severe tire damage.
