9-58 Driving and Operating
When the System Does Not
Seem to Work Properly
The system may not detect lanes as
well when there are:
.Close vehicles ahead.
.Sudden lighting changes, such
as when driving through tunnels.
.Banked roads.
If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
LDW alerts may occur due to tar
marks, shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LDW off if these
conditions continue.
Charging
Plug-In Charging
This section explains the process
for charging the vehicle's high
voltage battery. Do not allow the
vehicle to remain in temperature
extremes for long periods without
being driven or plugged in. It is
recommended that the vehicle be
plugged in when temperatures are
below 0°C (32°F) and above 32°C
(90°F) to maximize high voltage
battery life.
When using a 120-volt AC electrical
outlet, it will take approximately
12.5 hours to charge the vehicle
with the 12 amp AC current setting
or 18 hours using the default 8 amp
AC current setting. When using
a 240-volt charging station, it will
take approximately five hours to
charge the vehicle. Charge times
will vary with outside temperature. There are three ways to program
how the vehicle is charged. See
Programmable Charging on
page 5-29.
The charging system may run fans
and pumps that result in sounds
from the vehicle while it is turned
off. Additional unexpected clicking
sounds may be caused by the
electrical devices used while
charging.
While the charge cord is plugged
into the vehicle, the vehicle cannot
be driven.
Charging
Start Charge
1. Make sure the vehicle is parked
and turned off.
2. Push the rearward edge of the charge port door in and release
to open the door.

2. Disconnect the vehicle plug ofthe charge cord from the vehicle.
3. Close the charge port door by pressing firmly on the rearward
edge of the door surface.
4. Unplug the charge cord from the electrical outlet.
5. Place the charge cord into the storage compartment.
Delayed Charging
Override
To temporarily override a delayed
charge event, unplug the charge
cord from the charge port and then
plug it back in within five seconds.
A single horn chirp will sound and
charging will begin immediately.
To cancel a temporary override,
unplug the charge cord, wait for
10 seconds, and then plug the
charge cord back in. A double horn
chirp will sound and charging will be
delayed.
See Programmable Charging on
page 5-29 for advanced charge
scheduling options.
Charging Status
Feedback
The vehicle has two ways of
monitoring the charging status of
the high voltage battery. The
Instrument Panel Charging Status
Indicator (CSI) is at the center of the
instrument panel near the
windshield. The LEDs in the Outside
Rearview Mirrors (OSRVM) are also
used to monitor charging status.
Some local laws restricting the use
of colored lights on public roads
may apply to the outside rearview
mirrors charging status feedback. To
turn the OSRVM charge indicator
off, see “Charge Status Feedback”
in Vehicle Personalization on
page 5-52.

Important Information About
Portable Electric Vehicle Charging
.Charging an electric vehicle can
stress a building’ s electrical
system more than a typical
household appliance.
.Before you plug in to any
electrical outlet, have a qualified
electrician inspect and verify the
electrical system (electrical
outlet, wiring, junctions, and
protection devices) for
heavy-duty service at a 12 amp
continuous load.
.Electrical outlets may wear out
with normal usage or be
damaged over time, making
them unsuitable for electric
vehicle charging.
.Check the electrical outlet/plug
while charging and discontinue
use if the electrical outlet/plug is
hot, then have the electrical
outlet serviced by a qualified
electrician.
.When outdoors, plug into an
electrical outlet that is
weather-proof while in use.
.Mount the charging cord to
reduce strain on the electrical
outlet/plug.

Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. SeeEngine
Compartment Overview on
page 10-8 for reservoir location.
{Caution
.Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.
.Do not mix water with
ready-to-use washer fluid.
Water can cause the solution
(Continued)
Caution (Continued)
to freeze and damage the
washer fluid tank and other
parts of the washer system.
.When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
.Fill the washer fluid tank only
three-quarters full when it is
very cold. This allows for fluid
expansion if freezing occurs,
which could damage the tank
if it is completely full.
Brakes
This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time when the vehicle
is moving, except when applying the
brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
{Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the

10-22 Vehicle Care
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light on page 5-20.
Checking Brake Fluid
Check brake fluid by looking at the
brake fluid reservoir. See Engine
Compartment Overview on
page 10-8.
With the vehicle not running for at
least one minute, the maximum fluid
level (1) is at the top of the reservoir
body. With the vehicle running, the
fluid level should be in the proper
operating range (2) between the
MIN and MAX marks. If it is not,
have the brake hydraulic system
checked to see if there is a leak. After work is done on the brake
hydraulic system, make sure the
level, with the vehicle running, is in
the proper operating range (2)
between the MIN and MAX marks.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11-12.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{Warning
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid.
