Regenerative Braking

Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored
back into the high voltage battery
system, contributing to increased
energy efficiency.
The hydraulic disc brakes work with
the regenerative braking to ensure
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.
See Warning Lights, Gauges, and
Indicators on page 5 8 and Driver
Information Center (DIC) on
page 5 41. In the event of a
controller problem, the brake pedal
may be harder to push and the
stopping distance may be longer.
Ride Control Systems
Traction Control

System (TCS)

The vehicle has a Traction Control
System (TCS) that limits wheel spin.
The system operates if it senses
that one or both of the drive wheels
are slipping or beginning to lose
traction. When this happens, the
system brakes the spinning wheel(s)
and/or reduces power to limit
wheel spin.
The system may be heard or felt
while it is working, but this is
normal.
To assist with directional control of
the vehicle, TCS automatically
comes on whenever the vehicle is
turned on. To limit wheel spin,
especially in slippery road
conditions, the system should
always be left on. But, TCS can be
turned off if needed.
