Operation of each component
GS350_OM_OM30D41U_(U)
■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 di sable 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 angl e 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 cleare d using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. ( P. 3 74 )
■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 2 )
■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 2 )

Gently depress the accelerator pedal.
Release the parking brake.
■When starting off on a uphill
The hill-start assist control is available. (P. 277)
■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 speed may become high while driving. This is
due to automatic up-shifting control or do wn-shifting implementation to meet driv-
ing conditions. It does not indicate sudden acceleration.

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 will
result 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 depres s 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.
