REGENERATIVE BRAKING
SYSTEM (RBS)
Your vehicle has a RBS. The RBS replenishes the vehicle's
high voltage battery during deceleration, and is particularly
useful in stop-and-go city traffic. The electric motors, which
propel the vehicle forward, can operate as generators when
braking. The RBS recharges the high voltage battery under
certain braking conditions by recapturing energy that would
otherwise be lost while braking. The electric power that is
generated goes back into the high voltage battery for later
use, for example when acceleration is desired.
The RBS uses conventional hydraulic friction brakes,
regenerative braking, or a combination to slow the
vehicle. If the system detects slippery conditions while
braking, ONLY friction is used to slow the vehicle. The
RBS can result in extended life of the hydraulic service
brakes; however, all inspection, scheduled mainte-
nance, and service intervals for the vehicle service
brakes must be followed.
Max Regeneration
Max Regeneration is a supplemental feature of the
RBS. When activated, it will use the RBS to help slow
the vehicle when the driver releases the accelerator
pedal. This feature allows you to moderately reduce
driving speed without pressing the brake pedal. It is
always necessary to apply the brake pedal to bring the
vehicle to a complete stop. The Driving History screen
shows the value of energy recovered from the high-
voltage battery during eCoasting and eBraking energy
recovery operations page 29.
•eCoasting: Intervenes in place of the exhaust brake
when the throttle is released, allowing energy recov-
ery when slowing down, even when the brake pedal
is released. It will differentiate depending on select-
ing driving mode. When the accelerator pedal is
released, recovers energy during the slowing down
phase of the car. It it always active regardless of the
selected operating mode. eCoasting is possible if
the automatic transmission is in Drive. In “Natural”
and “Advanced Efficiency” modes, which can be
selected via the DNA system selector, eCoasting has
a setting that favors driving comfort. While in
“Dynamic” mode, eCoasting has a more pronounced
deceleration when the accelerator pedal is released.
•eBraking: eBraking is always active regardless of
the selected operating mode, and activates the
high-voltage battery charging when the brake pedal
is pressed, thereby recovering energy during brak-
ing. It is useful when driving in the city, where there
are continuous stops and starts. To make the most
efficient use the system, the braking phase should
be modulated by applying gradual pressure on the
brake pedal to allow maximum energy recovery.
E-SELEC MODE
This system allows the driver to select different modes by
pushing the following buttons located below the gear shifter.
•
Hybrid: Prioritizes electric range first, then gas range.
○Automatically switches between using gas and
battery for greatest efficiency and performance.
○
Best heating/cooling and acceleration performance.
•Electric: Prevents the engine from running, unless
you absolutely need it.
○
Driving in electric mode allows the vehicle to use up to
the full capability of the electric drivetrain, and if the
electric drivetrain is operating at its peak power, then
pressing the accelerator pedal more will not result in
more power. To access the full capability of the engine
plus electric motors, switch to Hybrid or e-Save.
○Engine will switch on during a Wide Open Throttle
(WOT) event, or if cruise control requires it.
○
Vehicle will switch to hybrid mode upon reaching <
1% State of Charge (SOC) or due to system needs.
See
page 84 for information on where to view
your vehicle’s SOC.
•e-Save: Aims to maintain a high level of SOC/Electric
range for later use. It can be customized in settings
to increase the SOC to predefined levels.
○e-Save settings can be found in the Uconnect
Hybrid Electric App.
○When e-Save is selected on a fully charged
vehicle, the SOC will drop slightly for optimal
performance.
○The Battery Save setting aims to maintain the
SOC at the current level. Under heavy load, such
as while pulling a trailer, SOC may decrease.
When coasting, the SOC may increase.
○The Battery Charge setting uses power from the
engine to increase SOC to the selected target. If
the SOC is above the target when e-Save mode is
activated, then the vehicle will automatically
switch between gas and battery until SOC
reaches the target.
○The e-Save mode button must be pressed to acti-
vate Battery Save or Battery Charge.
