Driving Information
Driving for Better Energy
Efficiency
Use the following tips to help maximize
energy efficiency and driving range.
In colder temperatures, while these
efficiency tips will help, the electric vehicle
driving range will be lower due to higher
energy usage including energy spent
heating the cabin.
The Range Impacts screen estimates the
influence of the main factors impacting
vehicle range. After charging is complete,
this information is reset. See“Range
Impacts” under. See Energy Information
0 97.
Acceleration/Braking/Coasting
Avoid rapid accelerations and decelerations.
Driving range is maximized at 89 km/h
(55 mph) and less.
Use cruise control when appropriate.
Plan ahead for decelerations and coast
whenever possible. Do not rush to traffic
signals. Do not shift to N (Neutral) to coast. The vehicle recovers more energy while
coasting and braking with One-Pedal mode
turned on. See
One-Pedal Driving 0171.
Using the Regen on Demand paddle during
deceleration recovers more energy. See
Regenerative Braking 0174.
Terrain and Vehicle Speed
Higher speeds and grade changes use more
energy and can significantly reduce driving
range.
Climate Setting
Using the heat and air conditioning systems
decreases the energy available for electric
driving.
Optimal energy efficiency is achieved when
the heat, air conditioning, and fan are
turned off.
Use the heated seat features instead of
climate control system. Heating the seat
uses less energy than heating and cooling
the interior.
Use remote start to heat or cool the interior
when the vehicle is plugged in to maximize
the driving range by utilizing electricity from
the electrical outlet. In hot weather, avoid parking in direct
sunlight or use sunshades inside the vehicle.
Keep the inside of the windows clean to
reduce fogging. Turn off the front defroster
and rear defogger when they are not
needed.
Avoid driving with the windows open at
highway speeds.
Use the Enhanced Battery Gauge on the
Instrument Cluster to view the effect of
climate control settings on your estimated
driving range. See
Battery Gauge (High
Voltage) 081.
Outside Temperature
On colder days, it is best to plug in the
vehicle overnight, then remote start the
vehicle.
Allow the vehicle to warm up for
20 minutes before driving.
If possible, use a level 2 (240 volt) high
power charge station for best results. This
allows the interior of the vehicle and high
voltage battery to warm to the optimal
temperature.

160 Driving and Operating
.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.
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.

Driving and Operating 161
{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, crash).
.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 IceCaution
To avoid damage to the wheels and
brake components, always clear snow and
ice from inside the wheels and
underneath the vehicle before driving.
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:
.Turn off One-Pedal Driving.
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on the Traction Control
System (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.
.Avoid using Regen on Demand paddle.
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
0 289. To get help and keep everyone in
the vehicle safe:
.Turn on the hazard warning flashers.
.Tie a red cloth to an outside mirror.
To save energy, run the vehicle for only
short periods as needed to warm the vehicle
and then shut the vehicle off and partially
close the window. Moving about to keep
warm also helps.

174 Driving and Operating
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
driving may result in injury, death,
or vehicle damage. SeeDefensive Driving
0 157.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) prevents the vehicle from
rolling in an unintended direction during the
transition from brake pedal release to
accelerator pedal apply. The brakes release
when the accelerator pedal is applied. If the
accelerator pedal is not applied within a few
minutes, the Electric Parking Brake will
apply. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.
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 brake system uses regenerative braking,
conventional hydraulic braking, or a
combination of both as appropriate.
The brake controller applies the hydraulic
brakes using a pump. The pump may be
heard during some braking, such as rapid
applies. This is normal.
Regen on Demand
Regen on Demand allows increased
deceleration by pressing and holding the
steering wheel paddle. It works in D (Drive).
Regen on Demand can add additional
regenerative braking when One-Pedal Drive
mode is enabled. The accelerator pedal can
be used to manage deceleration while using
Regen on Demand. See “One-Pedal Driving”
under Electric Drive Unit 0169.
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.
Regenerative power may be limited when
the battery is near full charge or cold.
Cruise control will turn off and the brake
lamps may come on when this feature is
activated.

Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control System
(TCS) and StabiliTrak/Electronic Stability
Control (ESC), 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/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path.
If cruise control or adaptive cruise control is
being used and TCS or StabiliTrak/ESC begins
to limit wheel spin, cruise control oradaptive cruise control will disengage. Cruise
control or adaptive cruise control may be
turned back on when road conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See
“Turning the Systems Off and On”
later in
this section.
The indicator light for both systems is in the
instrument cluster. This light will:
.Flash when TCS is limiting wheel spin.
.Flash when StabiliTrak/ESC is activated.
.Turn on and stay on when either system
is not working. If either system fails to turn on or to
activate, a message displays in the Driver
Information Center (DIC), and
dcomes on
and stays on to indicate that the system is
inactive and is not assisting the driver in
maintaining control. The vehicle is safe to
drive, but driving should be adjusted
accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the vehicle off and wait 15 seconds.
3. Start the vehicle.
Drive the vehicle. If
dcomes on and stays
on, the vehicle may need more time to
diagnose the problem. If the condition
persists, see your dealer.

Adding accessories can affect the vehicle
performance. See Accessories and
Modifications 0217.
Cruise Control
The cruise control lets the vehicle maintain a
speed of about 40 km/h (25 mph) or more
without keeping your foot on the
accelerator. Cruise control does not work at
speeds below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous where
you cannot drive safely at a steady
speed. Do not use cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
With the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC),
the system may begin to limit wheel spin
while you are using cruise control. If this
happens, the cruise control will
automatically disengage. See Traction
Control/Electronic Stability Control 0175. If a
collision alert occurs when cruise control is
activated, cruise control is disengaged. See
Forward Collision Alert (FCA) System 0192.
When road conditions allow you to safely
use it again, cruise control can be turned
back on.
If the brakes or the Regen on Demand
paddle are applied, cruise control
disengages.

Cruise control will disengage if either TCS or
StabiliTrak/ESC is turned off.
5:Press to turn the cruise control system
on and off. A white indicator comes on in
the instrument cluster when cruise is
turned on.
*: Press to disengage cruise control
without erasing the set speed from memory.
+RES : If there is a set speed in memory,
press briefly to resume that speed or press
and hold to accelerate. If cruise control is
already active, use to increase vehicle speed. −SET :
Press briefly to set the speed and
activate cruise control. If cruise control is
already active, use to decrease vehicle
speed.
Setting Cruise Control
If
5is on when not in use, −SET or +RES
could get bumped and go into cruise when
not desired. Keep
5off when cruise is not
being used.
To set a speed:
1. Press
5to turn the cruise system on.
2. Get up to the desired speed.
3. Press and release −SET. The desired set
speed briefly appears in the instrument
cluster.
4. Remove foot from the accelerator pedal.
The cruise control indicator on the
instrument cluster turns green after cruise
control has been set to the desired speed.
See Instrument Cluster 079.
Resuming a Set Speed
If the cruise control is set at a desired speed
and then the brakes are applied or
*is
pressed, the cruise control is disengaged
without erasing the set speed from memory. Once the vehicle speed reaches about
40 km/h (25 mph) or more, briefly press
+RES. The vehicle returns to the previous set
speed.
Increasing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Press and hold +RES until the vehicle
accelerates to the desired speed, then
release it.
.To increase the speed in small increments,
briefly press +RES. For each press, the
vehicle goes about 1 km/h (1 mph) faster.
The speedometer reading can be displayed
in either English or metric units. See
Instrument Cluster 079. The increment
value used depends on the units displayed.
Reducing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Press and hold −SET until the desired
lower speed is reached, then release it.
.To slow down in small increments, briefly
press −SET. For each press, the vehicle
goes about 1 km/h (1 mph) slower.

178 Driving and Operating
The speedometer reading can be displayed
in either English or metric units. See
Instrument Cluster079. The increment
value used depends on the units displayed.
Passing Another Vehicle While Using Cruise
Control
Use the accelerator pedal to increase the
vehicle speed. When you take your foot off
the pedal, the vehicle will slow down to the
previous set cruise speed. While pressing the
accelerator pedal or shortly following the
release to override cruise control, briefly
pressing −SET will result in cruise control set
to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works on hills
depends upon the vehicle speed, load, and
the steepness of the hills. When going up
steep hills, you might have to step on the
accelerator pedal to maintain the vehicle
speed. When going downhill, you might
have to brake or shift to a lower gear to
keep your speed down. If the brake pedal is
applied, cruise control will disengage.
Ending Cruise Control
There are five ways to end cruise control:
.Step lightly on the brake pedal.
.Press*.
.Shift the electric drive unit to N (Neutral).
.Press5to turn the cruise control system
off completely.
.Activate Regen on Demand. See “Regen
on Demand” underRegenerative Braking
0 174.
Erasing Speed Memory
The cruise control set speed is erased from
memory if
5is pressed or if the vehicle is
turned off.
Adaptive Cruise Control (Camera)
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and
following gap to be selected. Read this
entire section before using this system. The
following gap is the following time between
your vehicle and a vehicle detected directly
ahead in your path, moving in the same
direction. If no vehicle is detected in your
path, ACC works like regular cruise control.
ACC uses a windshield mounted front
camera sensor.
If a vehicle is detected in your path, ACC can
apply acceleration or limited, moderate
braking to maintain the selected following
gap. To disengage ACC, apply the brake. If ACC is controlling the vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC)
system activates, ACC may automatically
disengage. See
Traction Control/Electronic
Stability Control 0175. When road
conditions allow ACC to be safely used, ACC
can be turned back on.
When ACC is braking, a momentary motor
or clicking noise may be heard from the
Antilock Brake System (ABS). This is normal.
Disabling the TCS or StabiliTrak/ESC system
will disengage and prevent engagement
of ACC.
ACC can reduce the need for you to
frequently brake and accelerate, especially
when used on expressways, freeways, and
interstate highways. When used on other
roads, you may need to take over the
control of braking or acceleration more
often.
ACC automatically slows the vehicle down
while navigating the curve and may increase
speed out of the curve, but will not exceed
the set speed.
