NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitters, contact any authorized Lexus de aler or repairer, or another duly quali- fied and equipped professional as the tire pressure warning valves and transmitters may be damaged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire pressure warning valv es and the tire pressure warning valves could be bound.
●When replacing tire valve caps, do not use tire valve caps other than those specified.The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and trans- mitter may not operate properly. If a liquid sealant is used, contact any authorizedLexus dealer or repairer, or another duly qu alified and equipped professional or other
qualified service shop as soon as possible. After use of liquid sealant, make sure to replace the tire pressure warning valve and transmitter when repairing or replacing the tire. ( P. 537)
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes. These conditions may cause losses in tire inflation pressure, reducing the cushioning
ability of the tires. In addition, driving on rough roads may cause damage to the tires themselves, as well as the vehicle’s wheels and body.
■Low profile tires (except 17-inch tires)
Low profile tires may cause greater damage than usual to the tire wheel when sustain- ing impact from the road surface. Therefore, pay attention to the following:
●Be sure to use proper tire inflation pressu re. If tires are under-inflated, they may be
damaged more severely.
●Avoid potholes, uneven pavement, curbs an d other road hazards. Failure to do so may lead to severe tire and wheel damage.
■If tire inflation pressure of ea ch tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Remove the air conditioning filter
from the filter case and replace it
with a new one.
The “ UP” marks shown on the filter
and the filter case should be pointing up.
■Checking interval
Inspect and replace the air conditioning filt er according to the maintenance schedule. In dusty areas or areas with heavy traffic fl ow, 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.

NOTICE
■When using the air conditioning system
Make sure that a filter is always installed. Using the air conditioning system without a filter may cause damage to the system.

The following may indicate a problem with your transmission. Contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional or commercial towing service before towing.
●The engine is running but the vehicle does not move.
●The vehicle makes an abnormal sound.
If your vehicle needs to be towed
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 commercial towing se rvice, 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.

When trouble arises
RC200t_RC F_EE(OM24728E)
NOTICE
■When performing an emergency repair
●Perform the emergency repair without removing the nail or screw that has punctured the tread of the tire. If the object that has punctured the tire is removed, repair by the
emergency tire puncture repair kit may not be possible.
●The kit is not waterproof. Make sure that the kit is not exposed to water, such as when it is being used in the rain.
●Do not put the kit directly onto dusty ground such as sand at the side of the road. If thekit vacuums up dust etc., a malfunction may occur.
●Make sure to stand the kit with the bottle vertical. The kit cannot work properly if it is
laid on its side.
■Handling the emergency ti re puncture repair kit
●The compressor power source should be 12 V DC suitable for vehicle use. Do not
connect the compressor to any other source.
●If gasoline splatters on the kit, the kit may deteriorate. Take care not to allow gasoline to contact it.
●Store the emergency tire puncture repair kit in the trunk. The kit may be thrown around during sudden braking and so forth, damaging the kit.
●Store the kit in its assigned place out of reach of children.
●Do not disassemble or modify the kit. Do not subject parts such as the air pressure indicator to impacts. This may cause a malfunction.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and trans- mitter may not operate properly. If a liquid sealant is used, contact any authorizedLexus dealer or repairer, or another duly qu alified and equipped professional or other
qualified service shop as soon as possible. After use of liquid sealant, make sure to replace the tire pressure warning valve and transmitter when repairing or replacing the tire. ( P. 537)

Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil containers to help
you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN” means the oil quality designation by
American Petroleum Institute (API).
Center portion: “SAE 0W-20” means the SAE viscosity grade.
Lower portion: “Resource- Conserving” means that the oil hasfuel-saving and environmental pro-
tection capabilities.
ILSAC Certification Mark
The International Lubricant Specificatio n Advisory Committee (ILSAC) Certifica- tion Mark is displayed on the front of the container.

Oil viscosity (5W-30 is explained here as an example):
• The 5W in 5W-30 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 30 in 5W-30 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
