3-32 Seats and Restraints
Vehicles with eAssist have a high
voltage battery and a standard
12‐volt battery. If an airbag inflates
or the vehicle has been in a crash,
the vehicle's sensing system may
shut down the high voltage system.
When this occurs, the high voltage
battery is disconnected and the
vehicle is not charging the 12‐volt
battery or the electrical system. The
vehicle may start but it shuts down
once the 12‐volt battery is depleted.
When the 12‐volt battery is
depleted, the vehicle will not start
and the on‐board jump start feature
is disabled. The airbag readiness
light and/or the 12‐volt battery
warning light are displayed. Before
the vehicle can be operated again, it
must be serviced at your dealer.Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle's safety belts.The manufacturer's instructions that
come with the booster seat, state
the weight and height limitations for
that booster. Use a booster seat
with a lap-shoulder belt until the
child passes the below fit test:
.Sit all the way back on the seat.
Do the knees bend at the seat
edge? If yes, continue. If no,
return to the booster seat.
.Buckle the lap-shoulder belt.
Does the shoulder belt rest on
the shoulder? If yes, continue.
If no, then return to the
booster seat.
.Does the lap belt fit low and
snug on the hips, touching the
thighs? If yes, continue. If no,
return to the booster seat.
.Can proper safety belt fit be
maintained for the length of the
trip? If yes, continue. If no,
return to the booster seat.

loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steadypressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.

to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition
