Driving Information
Driving for Better Energy
Efficiency
Use the following tips to help
maximize energy efficiency and
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” underEnergy Information
0 115.
Acceleration/Braking/Coasting
Avoid rapid accelerations and
decelerations.
Electric 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, and do not
shift to N (Neutral) to coast.
The vehicle recovers more energy
while coasting and braking in
L (Low) than in D (Drive) mode.
Using the steering wheel paddle
during deceleration recovers more
energy. See
Regenerative Braking
0 194.
Terrain and Vehicle Speed
Higher speeds and grade changes
use more energy and can
significantly reduce electric 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 feature instead
of climate control system. Heating
the seat uses less energy than
heating the vehicle interior.
Use remote start to heat or cool the
interior when the vehicle is plugged
in to maximize the electric 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, and 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 range. See
Battery Gauge (High Voltage)
098.
Outside Temperature
On colder days, it is best to plug in
the vehicle overnight, and then
remote start the vehicle.

172 Driving and Operating
Allow the vehicle to warm up for
20 minutes before driving.
If possible, use a level 2 (32 amp)
high power charge station for best
results. This allows the interior of
the vehicle and high voltage battery
to warm to optimal temperature.
Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the
next drive. This is important when
outside temperatures are extremely
hot or cold.
Maintenance
Always keep the tires properly
inflated and the vehicle properly
aligned.
The weight of excess cargo in the
vehicle affects efficiency and range.
Avoid carrying more than is needed.
Avoid unnecessary use of electrical
accessories. Power used for
functions other than propelling the
vehicle will reduce EV range.Using a rooftop carrier will reduce
efficiency due to additional weight
and drag.
Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local
governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep
your eyes on the road, keep your
hands on the steering wheel, and
focus your attention on driving.
.
Do not use a mobile phone in
demanding driving situations.
Use a hands-free method to
place or receive necessary
phone calls.
. Watch the road. Do not read,
take notes, or look up
information on mobile phones or
other electronic devices. .
Designate a front seat
passenger to handle potential
distractions.
. Become familiar with vehicle
features before driving, such as
programming favorite radio
stations and adjusting climate
control and seat settings.
Program all trip information into
any navigation device prior to
driving.
. Wait until the vehicle is parked
to retrieve items that have fallen
to the floor.
. Stop or park the vehicle to tend
to children.
. Keep pets in an appropriate
carrier or restraint.
. Avoid stressful conversations
while driving, whether with a
passenger or on a mobile
phone.

It is not necessary to regularly
check coolant unless a leak is
suspected or an unusual noise is
heard. A coolant loss could indicate
a problem. Have it inspected and
repaired by your dealer.
The following explains the cooling
systems and how to check coolant
levels.

High Voltage Battery
During vehicle operation and also
during charging, the high voltage
battery cells in the vehicle are kept
within a normal operating
temperature range. If the
temperature rises above this
temperature, the battery cooling
system turns on the air conditioning
compressor and cools the coolant
until the correct temperature is reached. If the temperature falls
below this temperature, a high
voltage heater, located outside the
battery on a cradle, heats the
coolant until the correct temperature
is reached.
Single Power Inverter Module
(SPIM), Accessory Power
Module (APM), and Charger
Module
The SPIM, APM, and charger
module are cooled using a separate
coolant loop. These modules are
kept below a maximum temperature.
If the temperature rises above this
temperature, the electric cooling fan
will turn on to cool the coolant.
Cabin Heating
Cabin heating is maintained by
coolant heated by the Coolant
Heater Control Module (CHCM),
separate from the power electronics
and battery coolant loops. This
module heats the coolant based on
temperature inputs from the cabin
climate control systems.

274 Vehicle Care
Treadwear 200 Traction AA
Temperature A
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one and
one-half (1½) times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart significantly from the
norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.Traction
The traction grades, from
highest to lowest, are AA, A, B,
and C. Those grades represent
the tire's ability to stop on wet
pavement as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning, or peak traction
characteristics.
Temperature
The temperature grades are A
(the highest), B, and C,
representing the tire's resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled
conditions on a specified indoorlaboratory test wheel. Sustained
high temperature can cause the
material of the tire to degenerate
and reduce tire life, and
excessive temperature can lead
to sudden tire failure. The grade
C corresponds to a level of
performance which all
passenger car tires must meet
under the Federal Motor Safety
Standard No. 109. Grades B and
A represent higher levels of
performance on the laboratory
test wheel than the minimum
required by law. Warning: The
temperature grade for this tire is
established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
