120 Instruments and Controls
Antilock Brake System
(ABS) Warning Light
The ABS warning light will come on
briefly when the vehicle is started.
This is normal. If the light does not
come on then, have it fixed so it will
be ready to warn if there is a
problem.
If the light stays on or comes on
while driving, stop as soon as
possible and turn the vehicle off.
Then start the vehicle again to reset
the system. If the light still stays on,
or comes on again while driving, the
vehicle needs service. See your
dealer. If the regular brake system
warning light is not on, the brakes
will still work, but the antilock brakes
will not work. If the regular brake
system warning light is also on, theantilock brakes will not work and
there is a problem with the regular
brakes.
Sport Mode Light
This light comes on when Sport
Mode is selected.
Lane Keep Assist (LKA)
Light
If available, this light comes on
briefly while starting the vehicle.
If it does not come on, have the
vehicle serviced.This light is green if LKA is available
to assist.
LKA may assist by gently turning
the steering wheel if the vehicle
approaches a detected lane marking
without using the turn signal in that
direction. The LKA light will turn
amber.
This light is amber and flashes as a
Lane Departure Warning (LDW)
alert, to indicate that the lane
marking has been crossed.
Vehicle Ahead Indicator
If equipped, this indicator will
display green when a vehicle is
detected ahead and amber when
you are following a vehicle ahead
much too closely

Driving and Operating 195
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
. Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues —such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
. Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate. Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.
Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth.
. Turn off cruise control.

10122739) - 2017 - CRC - 10/3/16
196 Driving and Operating
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain.
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
electric drive unit.
. Keep the vehicle in gear when
going down steep or long hills.
{Warning
Coasting downhill in N (Neutral)
or with the vehicle turned off is
dangerous. The brakes will have
to do all the work of slowing down
the vehicle and could become too
hot. Hot brakes may not be able
to slow the vehicle enough to
maintain speed and control. You
could crash. Always have the
vehicle running and in gear when
going downhill. This will allow the
electric drive unit to assist in
slowing and maintaining speed. .
Drive at speeds to keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills.
Something could be in your lane
(e.g., stalled car, accident).
. Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick. .
Turn on TCS.
. The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner
than when on dry pavement.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 031. To get
help and keep everyone in the
vehicle safe:
. Turn on the hazard warning
flashers.

service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off, and
the brake pedal not applied,
pressing and holding POWER
Ofor
more than five seconds will place
the vehicle in Service Mode. The
instruments and audio systems will
operate as they do in ON/RUN, but
the vehicle will not be able to be
driven. The propulsion system will
not start in Service Mode. Press
POWER
Oagain to turn the
vehicle off.
Caution
Placing the vehicle in Service
Mode will use the 12-volt battery.
Do not use Service Mode for an
extended period, or the vehicle
may not start.
STOPPING THE VEHICLE/OFF :
To turn the vehicle off, press
POWER
Owith the vehicle in
P (Park). Retained Accessory Power
(RAP) will remain active until the
driver door is opened. When turning
off the vehicle, if the vehicle is not in
P (Park), the gear will go to P (Park)
and then power off automatically.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop, shift to P (Park), and turn the vehicle
off by pressing POWER

Driving and Operating 209
Caution
Spinning the tires excessively
may damage the electric drive
unit. The repair will not be
covered by the vehicle warranty.
If you are stuck, do not spin the
tires. When stopping on a steep
hill, use the brakes to hold the
vehicle in place.
L : This position reduces vehicle
speed without using the brakes. Use
L (Low) on very steep hills, deep
snow, in mud, or in stop-and-go
traffic.
One-Pedal Driving
With One-Pedal Driving, the
accelerator pedal can be used to
control the deceleration of the
vehicle down to a complete stop. Completely lifting off the accelerator
pedal will result in aggressive
deceleration. Slowly lifting off the
accelerator pedal will allow the
deceleration of the vehicle to be
adjusted as desired.
To use One-Pedal Driving, place
vehicle in L (Low). Press the
accelerator pedal to the desired
speed. The deceleration provided by
One-Pedal Driving provides full
regenerative braking and helps
increase energy efficiency.
While driving on grades, One-Pedal
Driving may not be able to bring the
vehicle to a complete stop or hold
the vehicle at a stop.
If the vehicle cannot maintain the
grade while using One-Pedal
Driving, the Electric Parking
Brake (EPB) may apply to hold the
vehicle stationary. To drive again,
press the accelerator pedal, and the
EPB will automatically disengage.One-Pedal Driving may become
disabled and the vehicle may
continue to creep forward, or if
stopped, may apply the EPB or shift
to park. This can be caused by the
following:
.
The drivers door is open.
. The drivers safety belt is
unbuckled.
. The vehicle has remained
stationary for five minutes.
. There is a problem with the
propulsion system.
Additional deceleration can be
achieved by using the Regen on
Demand paddle. See Regenerative
Braking 0212.

10122739) - 2017 - CRC - 10/3/16
210 Driving and Operating
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When propulsion is active and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 120. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Electric Parking Brake

212 Driving and Operating
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver hasquickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
The Hill Start Assist (HSA) feature
will activate when the vehicle is
stopped on a moderate to steep
grade to help prevent it from rolling
in an unintended direction. After the
brake pedal has been released and
before the accelerator pedal has
been pressed, HSA uses braking
pressure to hold the vehicle
stationary. If HSA is holding the
vehicle, a DIC message displays.HSA will not activate in a forward
drive gear when facing downhill,
or in R (Reverse) when facing uphill.
Regenerative Braking
Some braking energy from the
moving vehicle is turned back into
electrical energy. This energy is
then stored back into the high
voltage battery system, increasing
energy efficiency.
The hydraulic disc brakes will
become active and work to slow the
vehicle once the energy generated
from the regenerative braking has
been maximized, or if the battery is
fully charged.

Driving and Operating 213
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.
Cruise control will turn off and the
brake lamps may come on when
this feature is activated.
If the vehicle is in D (Drive) and 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. Theaccelerator pedal must be pressed
to move the vehicle forward. See
“One-Pedal Driving”
underElectric
Drive Unit 0206.
If the vehicle is on a steep grade,
the brake pedal must be used to
hold the vehicle.
Hill Top Reserve
Hill Top Reserve enables
regenerative braking efficiency to be
maximized when driving from a
higher elevation immediately after
charging. When turned on, this
feature will stop the charge before
the battery is full, allowing space for
energy from regenerative braking.
This feature also integrates with the
Location Based Charging feature,
allowing the system to be
configured so it is enabled when at
home (On - Home Only) or
away (On - Away Only). See
“Location Based Charging” under
Programmable Charging 0124.
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control 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.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of the
