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 controllerinterprets 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 5‑43. 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.

Turning the System On and Off
The UFRPA system can be turned
on and off by pressing the park
assist button in the overhead
console.
The park assist button lights up
when the system is on and turns
off when it has been disabled.
When the System Does Not
Seem to Work Properly
If UFRPA does not turn on due to a
temporary condition, the message
PARK ASSIST OFF displays on the
DIC, and the light on the park assist
button turns off. This can occur
under the following conditions:
.The ultrasonic sensors are not
clean. Keep the sensors free of
mud, dirt, snow, ice, and slush.
For cleaning instructions, see
Exterior Care on page 10‑89.
.The vehicle was washed in cold
weather. This may cause frost
or ice to form in the park assist
sensors. Keep the sensors free
of frost or ice.
.An object was hanging out of the
hatch during the last drive cycle.
Once the attached object is
removed, UFRPA will return to
normal operation.
.The bumper is damaged.
Take the vehicle to your
dealer to repair the system.
.Other conditions may affect
system performance, such as
vibrations from a jackhammer or
the compression of air brakes
on a very large truck.
