194 Driving and Operating
Warning
Do not charge your vehicle s battery
above an 80% charge if you are going to
drive down long, steep grades such as
mountain passes. This provides room in
the battery for regenerative braking to
supplement your conventional brakes
during the descent. This is especially
important when towing a trailer, which
puts additional stress on your vehicle s
braking system.
See Charge Now under Charging 0 108
for information on setting charge limits.
See Hill and Mountain Roads 0 177 for
important information about driving on
grades.
The brake system uses regenerative braking,
conventional hydraulic braking, or a
combination of both as appropriate.
Regen on Demand
Regen on Demand allows increased
deceleration by pressing and holding the
steering wheel paddle. It works in D (Drive)
and L (Low). The accelerator pedal can be
used to manage deceleration while using
Regen on Demand. See One-Pedal Driving.
If the vehicle is brought to a complete stop
while the Regen on Demand paddle is held,
the vehicle will not creep forward when the
paddle is released. The accelerator pedal
must be pressed to move the vehicle
forward.
If the vehicle is on a steep grade, the brake
pedal must be used to hold the vehicle.
When available regenerative braking power
is limited, the hydraulic brakes may be
applied to make up the difference.
Cruise control will turn off and the brake
lamps may come on when this feature is
activated.
Avoid using Regen on Demand under
slippery road conditions. Use the brake
pedal as the primary braking device.

Ride Control Systems

Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control System
(TCS) and StabiliTrak/Electronic Stability
Control (ESC) system. These systems help
limit wheel slip and assist the driver in
maintaining control, especially on slippery
road conditions.
TCS activates if it senses that any of the
drive wheels are spinning or beginning to
lose traction. When this happens, TCS
applies the brakes to the spinning wheels
and reduces propulsion system power to
limit wheel spin.
