For safety and security
Make sure that you can see backward clea rly by adjusting the inside and outside
rear view mirrors properly. ( P. 141, 143)
Adjusting the mirrors
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the effec-
tiveness of the seat belt and head restraint.
●Do not place anything under the front seats.
Objects placed under the front seats may be come jammed in the seat tracks and stop
the seat from locking in place. This may lead to an accident and the adjustment mech-
anism may also be damaged.
●When driving over long distances, take regular breaks before you start to feel tired.
Also, if you feel tired or sleepy while drivin g, do not force yourself to continue driving
and take a break immediately.
