NOTICE
How to use the camera
The parking assist monitor may not operate properly in the following
cases, or if the precautions described below are not followed.
• If the back of the vehicle is hit, the position and mounting angle of the
camera may change.
• As the camera has a water proof construction, do not detach, disassem-
ble or modify it. This may cause incorrect operation.
• Do not strongly rub the camera lens. If the camera lens is scratched, it
cannot transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coat to
adhere to the camera. If this happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on
the vehicle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunction-
ing.
• When the camera is used under fluorescent lights, sodium light or mer-
cury light etc., the lights and the illuminated areas may appear to
flicker.
Do not expose the camera to strong impact as this could cause a malfunc-
tion. If this happens, have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible.

cate the system is activated. The
slip indicator will also start flash-
ing.

• The shift lever is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
Hill-start assist control cannot be operated while the slip indicator light is
illuminated.
Hill-start assist control

applied after the driver releases the brake pedal. The stop lights and the high
mounted stoplight turn on.
Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
If the slip indicator does not flash and the buzzer does not sound when the

3604-6. Driving tips
GS350/250_EE (OM30C36E)Perform the following according to the driving conditions:
Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing.
To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle’s roof, chassis, around
the tires or on the brakes.
Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to road
conditions.
Park the vehicle and move the shift lever to P without setting the
parking brake. The parking brake may freeze up, preventing it from
being released. If necessary, block the wheels to prevent inadver-
tent sliding or creeping.
