9-34 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 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 ‑ 9 and Driver
Information Center (DIC) on
page 5
‑ 38 . 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 spinning 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 comes on
automatically whenever the vehicle
is started and cannot be turned off.
When the vehicle is started and
begins to move, the system
performs several diagnostic checks
to ensure there are no problems.
The system may be heard or felt
while it is working. This is normal
and does not mean there is a
problem with the vehicle. The
system should initialize before the
vehicle reaches 32 km/h (20 mph).
In some cases, it may take
approximately 3.2 km (2 mi) of
driving before the system initializes.
The Traction Control System may
activate on dry or rough roads or
under conditions such as heavy
acceleration while turning or abrupt
changes in output from the electric
drive unit. When this happens, a
reduction in acceleration may be
noticed, or a noise or vibration may
be heard. This is normal.
The TCS/StabiliTrak warning light
will flash to indicate that the traction
control system is active.
