and odors.
Pressing this button cancels
automatic recirculation. Press
AUTO to return to automatic
operation; recirculation runs
automatically as needed.
Manual recirculation mode is
not available when in Defrost.
The climate control system
uses a sensor to automatically
detect high humidity inside the
vehicle. When high humidity is
detected, the climate control
system may adjust to outside
air supply, turn on the heater
and air conditioner, increase fan and temperature, and
direct more air to the
windshield. When the climate
control system does not
detect possible window
fogging, it returns to normal
operation. To turn Auto Defog
off or on, select Settings >

covered by the vehicle
warranty.
Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the
solar heat.The climate control system
uses the sensor information to
adjust the temperature, fan
speed, recirculation, and air
delivery mode for best
comfort.
If the sensor is covered, the
automatic climate control
system may not work properly.
Remote Start Climate
Control Operation :
The
climate control system may
run when the vehicle is started
remotely. The system uses the
driver’s previous settings to
heat or cool the inside of the
vehicle. The rear defog may
come on during remote start
based on cold ambient
conditions. The rear defog
indicator light does not come
on during a remote start.
If equipped with heated or
cooled seats, they may come
on during a remote start. See
Remote Start 015 and
Heated and Ventilated Front
Seats 045. Afterblow Feature
If equipped, under certain
conditions, the fan may stay
on or may turn on and off
several times after you turn
off and lock the vehicle. This is
normal.
Air Vents
Use the multi-function joystick
control on the front center
and side air vents to change
the direction of the airflow.
Air vents blow warm air on the
side windows in cold weather.
If floor, defog, or defrost
modes are selected, a small
amount of air will come from
the vents close to the window.
To fully open the front A/C
vents, turn the multi-function

194 Driving and Operating
Acceleration/Braking/
Coasting
Avoid rapid accelerations and
decelerations.
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.
Use the One-Pedal Driving
feature when appropriate to
help recover energy during
coasting and braking.
One-Pedal mode recovers
more energy while coasting
and braking than D (Drive)
mode. See One-Pedal Driving
0214.
Use the steering wheel Regen
on Demand paddle during
deceleration to help recover
energy. See Regenerative
Braking 0220. 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 and ventilated
seat features (if equipped)
instead of the climate control
system. Heating and
ventilating the seat uses less
energy than heating and
cooling the interior. See
Heated and Ventilated Front
Seats
045 and
Heated Rear Seats 049.
Use the Remote Start Climate
Control feature to heat or cool
the interior while the vehicle is
plugged in to use electricity from the electrical outlet
instead of using energy from
the battery. See Remote Start
0
15.
In hot weather, avoid parking
in direct sunlight. 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 Battery Gauge on the
Instrument Cluster to view the
effect of climate control
settings on your estimated
range. See Battery Gauge
(High Voltage) 0110.
Outside Temperature
On colder days, it is best to
plug in the vehicle overnight,
and then remote start the
vehicle.

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. See Tires 0334.

200 Driving and Operating
.Turn off cruise control.
Hill and Mountain
Roads
{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.
If the battery becomes full,
regenerative braking will be
limited or unavailable. The
brakes will have to do all the
work of slowing down the
vehicle and could become(Continued)
Warning (Continued)
too hot. Hot brakes may not
be able to slow the vehicle
enough to maintain speed
and control. To help avoid
the risk of a crash, limit the
battery’s charge and, if you
experience brake fade or
receive a brake warning,
stop the vehicle and allow
the brakes to cool.
See“Charge Now” under
Charging 0123 for
information on setting
charge limits.
Driving on steep hills or
through mountains is different
than driving on flat or rolling
terrain. Be sure to:
.Use regenerative braking to
help slow the vehicle or
maintain speed by keeping
the vehicle in gear and
limiting the initial battery
charge to 80% or less.
.When braking is necessary,
use frequent, light taps of
the brake pedal. This
maximizes regenerative
braking and minimizes the
load on the vehicle brake
system.
.Keep the vehicle serviced
and in good shape.
.Check all fluid levels, brakes,
tires and cooling system.
.Drive at speeds that 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.

216 Driving and Operating
Brakes
Electric Brake Boost
Vehicles equipped with
electric brake boost have
hydraulic brake circuits that
are electronically controlled
when the brake pedal is
applied during normal
operation. The system
performs routine tests and
turns off within a few minutes
after the vehicle is turned off.
Noise may be heard during
this time. If the brake pedal is
pressed during the tests or
when the electric brake boost
system is off, a noticeable
change in pedal force and
travel may be felt. This is
normal.
Antilock Brake
System (ABS)
The Antilock Brake System
(ABS) helps prevent a braking
skid and maintain steering
while braking hard.
ABS performs a system check
when the vehicle is first driven.
A momentary motor or clicking
noise may be heard while this
test is going on, and the brake
pedal may move slightly. This
is normal.
If there is a problem with ABS,
this warning light stays on.
See Antilock Brake System
(ABS) Warning Light0117. ABS does not change the time
needed to get a foot on the
brake pedal and does not
always decrease stopping
distance. If you get too close
to the vehicle ahead, there will
not be enough time to apply
the brakes if that vehicle
suddenly slows or stops.
Always leave enough room
ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just
hold the brake pedal down
firmly. Hearing or feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and
braking at the same time. In
many emergencies, steering
can help even more than
braking.

Electric Parking Brake
The Electric Parking Brake
(EPB) can always be applied,
even if the vehicle is off. In
case of insufficient electrical
power, the EPB cannot be
applied or released. To
prevent draining the battery,
avoid unnecessary repeated
cycles of the EPB.
The system has a red parking
brake status light and an
amber service parking brake
warning light. See Electric
Parking Brake Light0116 and Service Electric Parking Brake
Light
0116. There are also
parking brake-related Driver
Information Center (DIC)
messages.
Before leaving the vehicle,
check the red parking brake
status light to ensure that the
parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The red parking brake status
light will flash and then stay on
once the EPB is fully applied.
If the red parking brake status
light flashes continuously, then
the EPB is only partially
applied or there is a problem
with the EPB. A DIC message
will display. Release the EPB
and try to apply it again. If the
light does not come on,
or keeps flashing, have the
vehicle serviced. Do not drive the vehicle if the red parking
brake status light is flashing,
see your dealer.
If the amber service parking
brake warning light is on,
press the EPB switch.
Continue to hold the switch
until the red parking brake
status light remains on. If the
amber service parking brake
warning light is on, see your
dealer.
If the EPB is applied while the
vehicle is moving, the vehicle
will decelerate as long as the
switch is pressed. If the switch
is pressed until the vehicle
comes to a stop, the EPB will
remain applied.
The vehicle may automatically
apply the EPB in some
situations when the vehicle is
not moving. This is normal, and
is done to periodically check
the correct operation of the
EPB system, or at the request
of other safety functions that
utilize the EPB.
