GS350/250_EE (OM30C36E)
NOTICE
Cleaning detergents
Do not use the following types of detergent, as they may discolor the vehi-
cle interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline,
alkaline or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alco-
hol
Do not use polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.
Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces:
Remove any dust or dirt from leather surfaces immediately.
Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.
When cleaning the inside of the windshield (vehicles with LKA [Lane-
Keeping Assist])
Be careful not to touch the camera sensor (P. 274).
If the camera is accidentally scratched or hit, LKA may not operate prop-
erly or may cause a malfunction.
Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause dam-
age to the rear window defogger heater wires or antenna. Use a cloth
dampened with lukewarm water to gently wipe the window clean. Wipe
the window in strokes running parallel to the heater wires or antenna.
Be careful not to scratch or damage the heater wires or antenna.
