For safe driving, adjust the seat and mirror to an appropriate position before driving.
Correct driving posture

Correct use of the seat belts
Make sure that all occupants are wearing their seat belts before driving the vehicle.
Use a child restraint system appropriate for the child until the child becomes large enough to properly wear the vehicle's seat belt.
Adjusting the mirrors
Make sure that you can see backward clearly by adjusting the inside and outside rear view mirrors properly.
WARNING Observe the following precautions.
Failure to do so may result in death or serious injury.
Doing so could cause the driver to lose control of the vehicle.
A cushion may prevent correct posture from being achieved, and reduce the effectiveness of the seat belt and head restraint.
Objects placed under the front seats may become jammed in the seat tracks and stop the seat from locking in place. This may lead to an accident and the adjustment mechanism may also be damaged.
Also, if you feel tired or sleepy while driving, do not force yourself to continue driving and take a break immediately.
