GETTING TO KNOW YOUR VEHICLE 7
If the battery temperature is below -22°F
(-30°C), or 131°F (55°C) or above, the vehicle
will NOT start:

If the vehicle is plugged in at these battery
temperatures, the instrument cluster will
display the message “Please Leave Key In
RUN — Battery Conditioning Needed”.

If the vehicle is not plugged in at these
battery temperatures, the “Plug In Vehicle To
Condition Battery” will be shown in the instru-
ment cluster display.
NOTE:

When the “Please Leave Key In RUN —
Battery Conditioning Needed” message is
displayed, keep the ignition in the RUN posi-
tion for the battery to recover. Place the igni-
tion back in the OFF position when the
message disappears, and then start the
vehicle. When this message is displayed, do
not operate any air conditioning controls.

Under these high or low temperatures while
the vehicle is plugged in, and the ignition is in
the OFF position, the vehicle may “wake up”
to precondition the high voltage battery for
use.

It is recommended that the vehicle be
plugged in overnight when possible to maxi-
mize the electric range of the vehicle.

It is recommended that the High Voltage
battery not be exposed to direct sunlight in
high temperature environments while the
vehicle is OFF. This may lower the life of the
battery.
The messages will only be displayed when the
ignition is in the RUN position and the high
voltage battery is not ready to provide
propulsion power. The messages also display if
there was a failed attempt to achieve READY
state when the high voltage battery cell
temperatures were either too cold, or too hot.

(RBS)
Your vehicle has a RBS. The RBS replenishes
the vehicle's high voltage battery during
deceleration, and is particularly useful in
stop-and-go city traffic. The electric motors,
which propel the vehicle forward, can operate
as generators when braking. The RBS recharges
the high voltage battery under certain braking
conditions by recapturing energy that would
otherwise be lost while braking. The electric
power that is generated goes back into the high
voltage battery for later use, for example when
acceleration is desired.
The RBS uses conventional hydraulic friction
brakes, regenerative braking, or a combination
to slow the vehicle. If the system detects
slippery conditions while braking, ONLY friction
is used to slow the vehicle. The RBS can result
in extended life of the hydraulic service brakes;
however, all inspection, scheduled
maintenance, and service intervals for the
vehicle service brakes must be followed.
Max Regeneration
Max Regeneration is a supplemental feature of
the RBS. When activated, it will use the RBS to
help slow the vehicle when the driver releases
the accelerator pedal. This feature allows you to
moderately reduce driving speed without
pressing the brake pedal. It is always necessary
to apply the brake pedal to bring the vehicle to
a complete stop.
