NOTICE
■If you get a flat tire while driving
A flat or damaged tire may
cause the following situations . Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.

●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 472, 483)
■When encountering flooded roads
Do not drive on a road that has flooded af ter heavy rain etc. Doing so may cause the
following serious damage to the vehicle:

WARNING
■To avoid malfunction of the camera sensor
Observe the following precautions.
Otherwise, the camera sensor may not operate properly, possibly leading to an acci-
dent resulting in deat h or serious injury.
●Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets, snow, etc.,
clear the windshield.
• If a glass coating agent is applied to the wi ndshield, it will still be necessary to use
the windshield wipers to remove water droplets, etc. from the area of the wind-
shield in front of the camera sensor.
• If the inner side of the windshield where th e camera sensor is installed is dirty, con-
tact your Lexus dealer.
●If the part of the windshield in front of the camera sensor is fogged up or covered with
condensation or ice, use the windshield defogger to remove the fog, condensation or
ice. ( →P. 314)
●If water droplets cannot be properly removed from the area of the windshield in front
of the camera sensor by th e windshield wipers, replace the wiper insert or wiper
blade.
If the wiper inserts or wiper blades need to be replaced, contact your Lexus dealer.
●Do not attach window tinting to the windshield.
●Replace the windshield if it is damaged or cracked.
If the windshield needs to be re placed, contact your Lexus dealer.
●Do not get the camera sensor wet.
●Do not allow bright lights to shine into the camera sensor.
●Do not dirty or damage the camera sensor.
When cleaning the inside of the windshield , do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
If the lens is dirty or damaged, contact your Lexus dealer.
●Do not subject the camera sensor to a strong impact.
●Do not change the installation position or direction of the camera sensor or remove it.
●Do not disassemble the camera sensor.
●Do not attach objects, such as stickers, trans-
parent stickers, etc., and so forth, to the outer
side of the windshield in front of the camera
sensor (shaded area in the illustration).
A: From the top of the windshield to approxi-
mately 0.4 in. (1 cm) below the bottom of the
camera sensor
B: Approximately 7.9 in. (20 cm) (Approxi-
mately 4.0 in. (10 cm) to the right and left
from the center of the camera sensor)

When trouble arises
*: Refer to the separate “Scheduled Mainte nance” or “Owner’s Manual Supplement”
for the maintenance interval applicable to your vehicle.
Indicates that the outside temperature is approximately
37° F (3 °C) or lower
A buzzer also sounds.
→ Drive carefully, as the road may be icy.
(GS350/GS300 only)
Indicates that the engine oil is scheduled to be changed
→Check the engine oil and change if necessary. After
changing the engine oil, the oil change system
should be reset. ( →P. 383)
(The indicator will not work properly unless the oil
maintenance data has been reset.)
(U.S.A. only)
Indicates that all maintenance according to the driven
distance on the maintenance schedule

formed soon. Comes on approximately 4500 miles (7200 km)
after the message has been reset.
→ If necessary, perform maintenance.
(GS350/GS300 only)
Indicates that the engine o il and oil filter should be
changed
→ Have the engine oil and oil filter checked and/or
changed by your Lexus dealer. After changing the
engine oil, the oil change system should be reset.

Vehicle specifications
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20
at the next oil change.
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 be fore the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscos ity 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 lo ad conditions.
How to read oil container label:
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is added
to some oil containers to help you
select the oil you should use.

■Engine oil selection
“Toyota Genuine Motor Oil” is used
in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 5W-30
SAE 5W-30 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 5W-30 is not available, SAE
10W-30 oil may be used. However,
it should be replaced with SAE 5W-
30 at the next oil change.
Oil viscosity (5W-30 is explained here as an example): • The 5W in 5W-30 indicates the charact eristic of the oil which allows cold
startability. Oils with a lower value be fore the W allow for easier starting of
the engine in cold weather.
• The 30 in 5W-30 indicates the viscos ity 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 lo ad conditions.
