IS350 AWD/IS350/IS300 AWD/IS300_U
■To stop the position recall operation part-way through
Perform any of the following operations:
●Press the “SET” button.
●Press button “1”, “2” or “3”.
●Operate any of the seat adjustment switches (only cancels seat position recall).

■Seat positions that can be memorized ( P. 143)
The adjusted positions other than the position adjusted by lumbar support switch can be
memorized.
■Operating the driving position memory after turning the engine switch off
Recorded seat positions can be activated up to 180 seconds after the driver’s door is
opened and another 60 seconds after it is closed again. Recorded steering wheel posi-
tion can be activated by pr essing the engine switch.
■In order to correctly use the dr iving position memory function
If a seat position is already in the furthest po ssible position and the seat is operated in the
same direction, the recorded position may be slightly different when it is recalled.

IS350 AWD/IS350/IS300 AWD/IS300_U
Each electronic key (including a card key) can be registered to recall your pre-
ferred driving position.
■Registering procedure
Record your driving position to button “1”, “2” or “3” before performing the
following:
Carry only the key you want to register, and then close the driver’s door. If 2 or
more keys are in the vehicle, the driving position cannot be recorded properly.
Check that the shift lever is in P.
Turn the engine switch to IGNITION ON mode.
Recall the driving position that you want to record.
While pressing the recalled but-
ton, press and hold the door lock
switch (either lock or unlock) until
the buzzer sounds.
If the button could not be registered,
the buzzer sounds continuously for
approximately 3 seconds.
■Recall procedureMake sure that the doors are locked before recalling the driving position.
Carry the electronic key that has been registered to the driving position,
and then unlock and open the driver’s door using the smart access system
with push-button start system or wireless remote control.
The driving position will move to the recorded position (not including the steering
wheel). However, the seat will move to a position slightly behind the recorded posi-
tion in order to make entering the vehicle easier.
If the driving position is in a position th at has already been recorded, the seat and
outside rear view mirrors will not move.
Turn the engine switch to ACCESS ORY mode or IGNITION ON mode,
or fasten a seat belt.
The seat and steering wheel will move to the recorded position.

IS350 AWD/IS350/IS300 AWD/IS300_U
When either “L” or “R” of the mirror select switch is selected, \
the outside rear
view mirrors will automatically angle down wards when the vehicle is reversing in
order to give a better view of the ground.
To disable this function, select neither “L” nor “R”.
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust th e mirror angle at a desired position.
The adjusted angle will be memorized and the mirror will automatically tilt to
the memorized angle whenever the shift lever is shifted to R from next t\
ime.
The memorized downward tilt position of th e mirror is linked to the normal position
(angle adjusted with the shif t lever in other than R). Ther efore, if the normal posi-
tion is changed after adjustment, the tilt position will also change.
When the normal position is chang ed, readjust the angle in reversing.
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■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. 422)
■Automatic adjustment of the mirror angle (if equipped)
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. ( P. 147)
■Auto anti-glare function (if equipped)
When the anti-glare inside re ar view mirror is set to automatic mode, the outside rear
view mirrors will activate in conjunction with the anti-glare inside rear view mirror to
reduce reflected light. ( P. 157)

Driving
IS350 AWD/IS350/IS300 AWD/IS300_U
WARNING
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 ped-
als 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 oper-
ating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay re sponse in an emergency, resulting in an accident.
●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.
●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. 515
●Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause th e brakes to overheat and lose effective-
ness. ( P. 191)
●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 across a river or th rough other bodies of water.
This may cause electric/elect ronic components to short circuit, damage the engine or
cause other serious damage to 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 no t before driving at such speeds.
