Safe Driving
■Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the trip. Slouching an d leaning reduces the effectiveness of
the belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat belt. If they do, they could be very
seriously injured in a crash.
• Do not put any accessories on the seat be lts. Devices intended to improve comfort
or reposition the shoulder part of a seat be lt can reduce the protective capability
and increase the chance of serious injury in a crash.
Your vehicle monitors front seat belt use. If
the power mode is set to ON before the
driver’s seat belt is fastened, a beeper will
sound and the indicator will blink. If the driver
does not fasten the belt before the beeper
stops, the indicator will remain on.
The beeper will also periodically sound and
the indicator will blink while driving until the
driver’s and front passenger’s seat belts are
fastened.
■Seat Belt Reminder
1 About Your Seat Belts
If a rear seat passenger moves around and extends
the seat belt, the lockable retractor may activate. If
this happens, release the retractor by unfastening the
seat belt and allow the belt to retract completely.
Then refasten the belt.
1Seat Belt Reminder
The indicator will also come on if a front passenger
does not fasten their seat be lt within 6 seconds after
the power mode is set to ON.
When no one is sitting in th e front passenger’s seat,
or a child or small adult is riding there, the indicator
will not come on.
This is because the weight sensors in the seat cannot
detect their presence.
