SEATS AND RESTRAINTS 97
The manufacturer 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 fit test below:
.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,
try using the rear seat belt
comfort guide, if available. See
“Rear Seat Belt Comfort Guides”
under Lap-Shoulder Belt 080. If a
comfort guide is not available, or if
the shoulder belt still does not rest
on the shoulder, 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 seat belt fit be
maintained for the length of the
trip? If yes, continue. If no, return
to the booster seat. Q: What is the proper way to wear
seat belts?
A: An older child should wear a
lap-shoulder belt and get the
additional restraint a shoulder belt
can provide. The shoulder belt
should not cross the face or neck.
The lap belt should fit snugly
below the hips, just touching the
top of the thighs. This applies belt
force to the child's pelvic bones in
a crash. It should never be worn
over the abdomen, which could
cause severe or even fatal internal
injuries in a crash.
Also see “Rear Seat Belt Comfort
Guides” underLap-Shoulder Belt 080.
According to accident statistics,
children are safer when properly
restrained in a rear seating position.
In a crash, children who are not
buckled up can strike other people
who are buckled up, or can be thrown
out of the vehicle. Older children need
to use seat belts properly.{Warning
Never allow more than one child to
wear the same seat belt. The seat
belt cannot properly spread the
impact forces. In a crash, they can
be crushed together and seriously
injured. A seat belt must be used by
only one person at a time.

will result in reduced, or no power. An
adequate fuel level must be
maintained in the vehicle to keep it
operational.
Fuel Maintenance Mode (FMM)
FMM tracks average fuel age. Old fuel
can cause engine problems. If low
engine usage causes average fuel age
to exceed approximately one year,
FMM will run the engine to use up
the old fuel. The engine will run until
enough fresh fuel is added to bring
the average fuel age into an
acceptable range. Allowing more old
fuel to be used up by FMM and
adding a larger amount of fresh fuel
will maximize the length of time
before another fuel maintenance
mode is needed. During FMM the
engine may turn on and off.
When FMM is needed, the FMM
Request screen appears on the
infotainment display at vehicle start.
If Yes is selected, FMM will begin. The
engine will not start until after a short
delay once shifted into D (Drive). FMM
will automatically continue at each
vehicle start until fresh fuel is added.
If No is selected, the FMM Request
screen will appear when the vehicle is
next started. The FMM request can be
delayed for only one day.If the FMM request was delayed for
one day, FMM will start at the next
vehicle start and display the FMM
Notification screen on the
infotainment display. The engine will
not start until after a short delay once
shifted into D (Drive).
If FMM is required and the fuel level
is low, FMM may eventually empty
the fuel tank if fuel is not added. This
will result in reduced, or no power. An
adequate fuel level must be
maintained in the vehicle to keep it
operational. After FMM has run it is
recommended to fill the fuel tank.
