Vehicle may shut down
unexpectedly
The electrical system cannot maintain the
voltage required to support all vehicle
features.
If you drive the vehicle while this alert is
present, certain features may be disabled or
function at a reduced level due to the low
voltage. It is also possible the vehicle will shut
down unexpectedly.
Try turning off non-critical features, like seat
heaters or cabin fans, to help the vehicle
maintain electrical power for as long as
possible.
Eliminating or reducing usage of non-critical
features may allow the vehicle to reach its
destination without shutting down, although
this is not guaranteed.
Schedule service before your next planned
drive. The vehicle may shut down
unexpectedly or may not restart without
service.
