passenger frontal airbag and knee
airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light 0113 for more information,
including important safety
information.
Charging System Light
(12-Volt Battery)
The charging system light comes on
briefly when the vehicle is started,
as a check to show the light is
working.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the 12-volt battery.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the vehicle is in
Service Mode. See Power Button
0 168.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.

Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
electric drive unit, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’s ability to pass(Continued)

Maintenance test. See
Accessories and Modifications
0237.
If the light is flashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If the light continues to flash, find a
safe place to park. Turn the vehicle
off and wait at least 10 seconds
before restarting the engine. If the
light is still flashing, follow the
previous guidelines and see your
dealer for service as soon as
possible. If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. A loose or missing fuel cap may
cause the light to come on. See
Filling the Tank 0230. A few
driving trips with the cap
properly installed may turn the
light off.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed
up. If this occurs, change the
fuel brand. It may require at
least one full tank of the proper
fuel to turn the light off. See
Recommended Fuel 0229.
If the light remains on, see your

by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
The oil pressure light should come
on briefly as the vehicle is started.
If it does not come on have the
vehicle serviced by your dealer.If the light comes on and stays on, it
means that oil is not flowing through

Programmable Charging
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 plugging into 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 may 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.

174 Driving and Operating
Electric Mode
In Electric Mode, the vehicle does
not use fuel or produce tailpipe
emissions. During this primary
mode, the vehicle is powered by
electrical energy stored in the high
voltage battery. The vehicle can
operate in this mode until the
battery has reached a low charge.
There are some conditions when the
battery charge is high enough to
provide Electric Mode operation, but
the engine still runs. They are:
.Cold ambient temperatures.
. Hot or cold high voltage battery
temperatures.
. The hood being open or not
completely closed and latched.
. Certain high voltage battery fault
conditions.
. Engine Maintenance Mode or
Fuel Maintenance Mode
being run.
Extended Range Mode
When the vehicle reaches the end
of its electric range, it switches to
Extended Range Mode (ERM). In
this secondary mode, electricity is
produced by the fuel-powered
engine. This secondary source of
electric power extends the vehicle
range. Operation will continue in
ERM until the vehicle can be
plugged in to recharge the high
voltage battery and restore
Electric Mode.
The high voltage battery will
continue to provide some power and
work together with the engine to
provide peak performance when it is
required, such as driving up a steep
incline or for high acceleration
maneuvers. The battery will not be
charged nor will electric vehicle
range be restored by the engine.
In either Electric Mode or Extended
Range Mode, when the hood is
open and the vehicle is moving at
low speed or stopped, the engine
will run without turning off if the
vehicle is on, except when the electric drive unit is in N (Neutral).
The engine will turn off or remain off
at low vehicle speed in N (Neutral).
The high voltage battery is not
charged when this occurs. Under
these conditions, the high voltage
battery can still be discharged
based on the vehicle loads such as
A/C, or 12-volt loads.
In either Electric Mode or Extended
Range Mode, if there is a high
voltage battery fault, the engine may
run without turning off to generate
needed electricity. The malfunction
indicator lamp will turn on. See
Malfunction Indicator Lamp (Check
Engine Light)
0114.
Driver Selected Operating
Modes
While driving in Electric or Extended
Range Mode, additional operating
modes can be selected.

Driving and Operating 183
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a
Yor PARK
Electric Parking Brake light, and
a
8Service Parking Brake light.
See Electric Parking Brake Light
0 117 and Service Electric Parking
Brake Light 0117.
Before leaving the vehicle, check for
the
Yor PARK 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. Pull the EPB switch momentarily.
The
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK light
