238 DRIVING AND OPERATING
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 hydraulic braking system
uses an electronic booster for boost
assist on demand, under certain
conditions a motor noise may be
heard. This is normal operation.
See Warning Lights, Gauges, and
Indicators 0 126 and Driver Information
Center (DIC) 0 162. In the event of a
controller problem, the brake pedal
may be harder to push and the
stopping distance may be longer.
Regen on Demand
Regen on Demand allows the user to
select increased coast deceleration by
pressing the steering wheel tap
controls. It is activated temporarily
while in D (Drive) and permanently
while in M (Manual Mode). Increased
coast deceleration will be felt while
the accelerator pedal is fully released
and lessened when the accelerator
pedal is pressed.
The brake pedal must be applied at
low speed, because Regen on Demand
will not stop the car.
The brake lamps may come on when
this feature is activated.
To enter Permanent Regen on
Demand Mode:
1. Move the shift lever from
D (Drive) to M (Manual Mode).
While in Permanent Regen on
Demand, the M of the PRNDM
section of the instrument cluster
will become highlighted, and the
current coast deceleration level is
indicated. Level 1 (M1) provides
the most coast deceleration.
Level 4 (M4) provides the least
coast deceleration and is
equivalent to the level found in
D (Drive).
2. Tap the left control on the back
of the steering wheel toward the
driver to select more coast
deceleration. Tap the right
control toward the driver to
select less coast deceleration. To
select the most coast
deceleration, press and hold the
left control.
3. To exit, move the shift lever back
to D (Drive).
With the shift lever in D (Drive) and
not in Permanent Regen on Demand
Mode, the Tap Shift controls will
activate Temporary Regen on
Demand. The vehicle exits Temporary
Regen on Demand after the
