20 GETTING TO KNOW YOUR VEHICLE

ONDITIONING
In extreme temperatures, high or low, the high
voltage battery may need to be conditioned, and
therefore may require the vehicle to be plugged in.
If the ambient temperature is 5°F (-15°C) or
below at vehicle shut down, the instrument cluster
will display the message “Plug In Vehicle To
Condition Battery”.
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 vehicle will not start and the
instrument cluster will display the message
“Please Leave Key In RUN — Battery Condi-
tioning Needed” until battery conditioning is
complete.

If the vehicle is not plugged in at these battery
temperatures, the vehicle will not start and the
“Plug In Vehicle To Condition Battery” message
will be shown in the instrument cluster display.
NOTE:

When the “Please Leave Key In RUN — Battery
Conditioning Needed” message is displayed,
keep the ignition in the RUN position for the
battery to recover. Place the ignition 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 maximize the elec-
tric range of the vehicle.
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 will 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.

YSTEM
(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.
