GS350_200t_GS F_OM_OM30E87E_(EE)
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.
■Changing interval
Inspect and replace the air conditioning filt er 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.
■Air conditioning filter with deodorizing function
When fragrances are placed in your vehicle, the deodorizing effect may become signifi-
cantly weakened in a short period.
When an air conditioning odor comes out cont inuously, replace the air conditioning filter.

If your vehicle needs to be towed
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.
Do not tow with a sling-type truck to
prevent body damage.
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 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.

GS350_200t_GS F_OM_OM30E87E_(EE)
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 repair kit is not waterproof. Make sure that the repair kit is not exposed to water,
such as when it is being used in the rain.
●Do not put the repair kit directly onto dusty ground such as sand at the side of the
road. If the repair kit vacuums up dust etc., a malfunction may occur.
■Handling the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle use. Do not con-
nect the repair kit to any other source.
●If gasoline splatters on the repair kit, the repair 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 repair kit in the trunk out of reach of children.
●Do not disassemble or modify the repair kit. Do not subject parts such as the air pres-
sure indicator to impacts. This may cause a malfunction.
■To avoid damage to the tire pressure warning valves and transmitters (vehicles with
the tire pressure warning system)
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 authorized
Lexus dealer or repairer, or another duly qu alified and equipped professional or other
qualified service shop as soon as possible. Make sure to replace the tire pressure warn-
ing valve and transmitter when repairing or replacing the tire. ( →P. 4 6 7 )

6148-1. Specifications
GS350_200t_GS F_OM_OM30E87E_(EE)
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 viscosit y 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-Conserv-
ing” means that the oil has fuel-saving
and environmental protection capa-
bilities.
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.
