WA R N I N G
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the selector lever is in
P (automatic transaxle) or in 1st gear or R
(manual transaxle):
Leaving the driver's seat without switching
the ignition off, setting the parking brake,
and shifting the selector lever to P
(automatic transaxle) or to 1st gear or R
(manual transaxle) is dangerous.
Unexpected vehicle movement could occur
which could result in an accident.
In addition, if your intention is to leave the
vehicle for even a short period, it is
important to switch the ignition off, as
leaving it in another position will disable
some of the vehicle's security systems and
run the battery down.
