Maintenance and care
GS350_250_OM_OM30E16E_(EE)
Wipe the dipstick and reinsert it fully.
■Adding engine oil
If the oil level is below or near the
low level mark, add engine oil of
the same type as that already in
the engine.
Make sure to check the oil type and prepare the items needed before
adding oil.Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.
■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following situa-
tions, oil consumption may increase, and engine oil may need to be refilled in
between oil maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle or after
replacing the engine
●If low quality oil or oil of an inappropriate viscosity is used
●When driving at high engine speeds or with a heavy load, when towing, or when
driving while accelerating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently through
heavy traffic

■Low profile tires (except 225/50R17 tires)
Generally, low profile tires will wear more rapidly and tire grip performance will be
reduced on snowy and/or icy roads when compared to standard tires. Be sure to use
snow tires or tire chains on snowy and/or icy roads and drive carefully at a speed
appropriate for road and weather conditions. (→P. 3 5 6 )
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
■Situations in which the tire pressure warning system may not operate properly
(vehicles with the tire pressure warning system)
●In the following cases, the tire pressure warning system may not operate properly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• Lock nuts are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels or
wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If the spare tire is in a location subject to poor radio wave signal reception.
*
• If a large metallic object which can interfere with signal reception is put in the trunk.
*
*
: Vehicles with a full-size spare tire only
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, airport or other facility that generates strong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wire- less communication device
Vehicles with the tire inflation pressure display function: If tire position information
is not correctly displayed due to the radio wave conditions, the display may be cor-
rected by driving and changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could
be extended.
●When tire inflation pressure declines rapidly for example when a tire has burst, the
warning may not function.

CAUTION
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dangerous
handling characteristics, which may lead to an accident resulting in death or seri-
ous injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Lexus.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
●Vehicles with a compact spare tire: Do not tow if your vehicle has a compact
spare tire installed.
●Vehicles with an emergency tire puncture repair kit (if equipped): Do not tow
anything if a tire that has been repaired using the emergency tire puncture repair
kit is installed. The load on the tire may cause unexpected damage to the tire.
■When initializing the tire pressure warning system (vehicles with the tire pressure
warning system)
Do not operate the tire pressure warning reset switch without first adjusting the tire
inflation pressure to the specified level. Otherwise, the tire pressure warning light
may not come on even if the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.

■Outer foot lightsPress the upper part of the out-
side rear view mirror to tilt the
mirror face upward, and apply
protective tape to the lower
part of the mirror cover.
Insert 2 flathead screwdrivers
wrapped in protective tape,
and disconnect the tabs
behind the mirror.
Pry the mirror out toward you, dis-
connecting the tabs 2 at a time.
Work carefully, ensuring that you
do not drop the mirror.
Disconnect the connectors
behind the mirror, and remove
the mirror.
When removing the thin connec-
tors, make sure to mark one of the
connectors with a piece of tape, to
avoid mixing them up when rein-
stalling.
Work carefully, ensuring that you
do not drop the mirror.
When handling the mirror, do not
touch the parts applied with
grease.
The number of connectors
equipped differs by vehicle specifi-
cation.

GS350_250_OM_OM30E16E_(EE)
If your Lexus is transported by a flat-
bed truck, it should be tied down at
the locations shown in the illustra-
tion.
If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45°.
Do not overly tighten the tie downs
or the vehicle may be damaged.
If a tow truck is not available in an emergency, your vehicle may be tempo-
rarily towed using a cable or chain secured to the emergency towing eye-
let. This should only be attempted on hard surfaced roads for 80 km
(50miles) at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The vehi-
cle’s wheels, drive train, axles, steer ing and brakes must be in good condi-
tion.
