Operation of each component
GS350_U (OM30C34U)
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■Linked mirror function when reversing
●When either “L” or “R” of the mirror select switch is selected, the outside rear view
mirrors will automatically angle downwards when the vehicle is reversing in order
to give a better view of the ground. To disable this function, select neither “L” nor
“R”.
●If the mirror angle adjustment switch is operated while the linked mirror function is
in operation, the angle and position of the mirrors can be remembered, and the
mirrors will operate at the angle adjusted to the last time the linked mirror function
was operated.
However, because the mirrors move based on the angle they are in when the linked
mirror function is not operating, the mirror angle when the linked mirror function is
operating will also be changed if the mirrors are adjusted while the function is not
operating.
■When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. (→P. 3 6 5 )
■Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automatically
by the driving position memory. ( →P. 1 3 0 )
■Auto anti-glare function
When the anti-glare inside rear view mirror is set to automatic mode, the outside
rear view mirrors will activate in conjunction with the anti-glare inside rear view mir-
ror to reduce reflected light. ( →P. 1 4 0 )

vant door.
●After stopping the vehicle, the window can be closed by holding the power window
switch in the one-touch closing position while the engine switch is turned to IGNI-
TION ON mode.
●If the window still cannot be closed even by carrying out the operation as explained
above, initialize the function by performing the following procedure.Hold the power window switch in the one-touch closing position. Continue
holding the switch for a further 6 seconds after the window has closed.
Hold the power window switch in the one-touch opening position. Continue
holding the switch for a further 2 seconds after the window has opened com-
pletely.
Hold the power window switch in the one-touch closing position once again.
Continue holding the switch for a further 2 seconds after the window has
closed.
If you release the switch while the window is moving, start again from the beginning.
If the window continues to close but then re-open slightly even after performing the
above procedure correctly, have the vehicle inspected by your Lexus dealer.

Driving
Make sure that the parking brake is set and shift the shift lever to D.
Gently depress the accelerator pedal.
Release the parking brake.
■When starting off on a uphill
The hill-start assist control is available. (→P. 2 76 )
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because there
may be a layer of water between the tires and the road surface, preventing the
steering and brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine spee d may become high while driving. This is
due to automatic up-shifting control or down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
●When sport mode is selected ( →P. 2 6 3 )

Driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine running.
This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal willresult in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and accelerator pedals prop-
erly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, resulting in an acci-
dent.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.

4-1. Before driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
●During normal driving, do not turn off the engine. Turning the engine off while
driving will not cause loss of steering or braking control, but the power assist to
these systems will be lost. This will make it more difficult to steer and brake, so you
should pull over and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop
the vehicle in the normal way: →P. 6 7 7
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. ( →P. 1 7 8 )
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.
