Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the vehicle. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
Service Only Mode, as a check to
show it is working. If it does not,
have the vehicle serviced by your
dealer. SeePower Button on
page 9-16 for more information.
If the malfunction indicator lamp
comes on, while the engine is in
ON/RUN, this indicates that the OBD II system has detected a
problem and diagnosis and service
might be required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the dealer technician in
correctly diagnosing any
malfunction.
{Caution
If the vehicle is continually driven
with this light on, the emission
controls might not work as well,
the vehicle fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.
{Caution
Modifications made to the engine,
electric drive unit, exhaust, intake,
or fuel system of the vehicle or
the replacement of the original
tires with other than those of the
same Tire Performance Criteria
(TPC) can affect the vehicle
emission controls and can cause
this light to come on.
Modifications to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure
to pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications on
page 10-2.

The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on while the vehicle is in ON/
RUN, or if the vehicle is placed
in Service Only Mode and the
malfunction indicator lamp does
not come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed by the
system. If this were to occur, the
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or
run down.
The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of driving. If this
has been done and the vehicle
still does not pass the inspection
for lack of OBD II system
readiness, your dealer can
prepare the vehicle for
inspection.Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
This light comes on briefly when the
vehicle is turned on. If it does not
come on then, have it fixed so it will
be ready to warn if there is a
problem.
If the light comes on and stays on,
there is a base brake problem.

When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds.
Objects Detected by Both the
Front and Rear Sensors (If
Equipped)
In general, if objects are detected at
the same time near both the front
and rear bumpers while backing up, the beeps only sound to indicate
that objects are close to the rear
bumper.
However, if an object comes within
0.3 m (1 ft) of the front bumper while
the vehicle is backing up and at the
same time there is another object
further than 0.3 m (1 ft) from the rear
bumper, then the beeps only sound
to indicate the object that is closer
to the front bumper.

9-46 Driving and Operating
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
the
@LANE DEPART button on the
steering wheel. The control indicator
will light when LDW is on.
When the vehicle is started, the
LDW indicator on the instrument
panel will come on briefly. If LDW is on, the LDW indicator will
appear green if the system detects
a left or right lane marking while the
vehicle is traveling 56 km/h (35 mph)
or greater. If the vehicle crosses a
detected lane marking without using
the turn signal, this indicator will
change to amber and flash. In
addition, three beeps will be
sounded from the left or right side,
depending on the lane departure
direction.
When the System Does Not
Seem To Work Properly
If the LDW symbol does not appear
when the system is on and the
vehicle is traveling at least 56 km/h
(35 mph):
.The lane markings on the road
may not be seen.
.The camera sensor may be
blocked by dirt, snow, or ice.
.The windshield may be
damaged.
.The weather may be limiting
visibility.
This is normal operation; the vehicle
does not need service. Clean the
windshield.
Lane markings may not be detected
on curves, highway exit ramps,
or hills; or due to poor visibility.
If the LDW camera system does not
seem to operate properly, cleaning
the outside of the windshield in front
of the camera sensor may correct
the issue.
{Warning
LDW does not provide a warning
to help avoid a crash, unless it
detects the lane markings. LDW
may not detect the lane markings
if the camera sensor is blocked
by dirt, snow, or ice, or if the
windshield is damaged. It may (Continued)

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.
{Warning
Improper use of portable electric
vehicle charge cords may cause
a fire, electrical shock, or burns,
and may result in damage to
property, serious injury, or death.
(Continued)
Warning (Continued)
.Do not use extension cords,
multi-outlet power strips,
splitters, grounding adaptors,
surge protectors, or similar
devices.
.Do not use an electrical outlet
that is worn or damaged,
or one that will not hold the
plug firmly in place.
.Do not use an electrical outlet
that is not properly grounded.
.Do not use an electrical outlet
that is on a circuit with other
electrical loads.
