2023-4. Adjusting the steering wheel and mirrors
GS350_250_OM_OM30E16E_(EE)
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■Rain clearing mirrors (if equipped)
When water droplets collects on the mirror surface, for example when it rains, the
rain clearing (hydrophilic) effect of the mirrors causes the droplets to be spread out
into a film making the rear view clearer. In the following cases, the rain clearing effect
will be reduced temporarily, but will return after 1 or 2 days’ exposure to direct sun-
light.
●After wiping dirt off the mirrors
●When the mirrors fog up
●After waxing your vehicle in an automatic car wash
●After your vehicle has been parked for a long period in underground parking lots
etc. where there is no direct sunlight
■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 9 6 )
■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 8 6 )
■Auto anti-glare function (if equipped)
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 9 7 )
■Using automatic mode in cold weather
When automatic mode is used in cold weather, the door mirror could freeze up and
automatic stowing and return may not be possible. In this event, remove any ice and
snow from the door mirror, then either operate the mirror using manual mode or
move the mirror by hand.

Driving
GS350_250_OM_OM30E16E_(EE)
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.

2184-1. Before driving
GS350_250_OM_OM30E16E_(EE)
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. 5 3 5
●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. 2 4 4 )
●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.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected.
