Driving and Operating 9-15
Excessively shifting the transfer
case into or out of the different
modes may cause the transfer case
to enter the shift protection mode.
This will protect the transfer case
from possible damage and will only
allow the transfer case to respond to
one shift per 10 seconds. The
transfer case may stay in this mode
for up to three minutes. Brakes
Regenerative Braking
Regenerative braking is a hybrid
technology that enables the electric
drive motor to operate as a
generator when coasting or braking.
Energy from the moving vehicle
recharges the hybrid battery.
The hydraulic disc brakes work with
the regenerative braking to insure
effective braking, such as when a
high braking demand is requested.
The braking system is computer
controlled and blends the
regenerative braking with the
conventional hydraulic disc brakes
to meet any requirements for
deceleration. The controller
interprets the braking request and
uses regenerative braking,
conventional hydraulic braking or a
combination of both as necessary.
Because the controller applies the
hydraulic brakes through its high
pressure accumulator, you may
occasionally hear the motor driven
pump when it recharges the system.
This is normal.
In the event of a controller problem,
the brake pedal may be harder to
push and the stopping distance may
be longer.
