This gauge indicates boost under
heavier throttle.
It displays the air pressure level in the
intake manifold before it enters the
engine's combustion chamber.
The gauge is automatically centered at
zero every time the engine is started.
Actual boost is displayed from this
zero point. Changes in ambient
pressure, such as driving in mountains
and changing weather, will slightly
change the zero reading.

(Base Level Cluster Only)
Metric Standard Theme
English Standard Theme
The engine oil pressure gauge shows
the engine oil pressure
in kPa (kilopascals) or psi (pounds per
square inch) when the engine is
running.
Oil pressure can vary with engine
speed, outside temperature, and oil
viscosity.
On some models, the oil pump will
vary engine oil pressure according to
engine needs. Oil pressure may change
quickly as the engine speed or load
varies. This is normal.

If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio and
air conditioner.
Charge Cord Connected
(PLUG-IN Only)
This light comes on when a charge
cord is connected to the vehicle.
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 ignition is in Service Mode. See
Ignition Positions0217.
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,
transmission, 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 an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0298.
If the light is f lashing : 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.

144 INSTRUMENTS AND CONTROLS
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:
. If fuel has been added to the
vehicle using the capless fuel
funnel adapter, make sure that it
has been removed. See “Filling the
Tank with a Portable Gas Can ”
under Filling the Tank 0288. The
diagnostic system can detect if the
adapter has been left installed in
the vehicle, allowing fuel to
evaporate into the atmosphere.
A few driving trips with the
adapter removed may turn off the
light.
. 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
Fuel0286.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
See Add-On Electrical Equipment 0295.
See your dealer if assistance is needed. The vehicle may not pass
inspection if:
.
The light is on when the engine is
running.
. The light does not come on when
the ignition is in Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.

Programmable Charge Modes
This vehicle has three programmable
charge modes. To view the current
charge mode status in the
infotainment display, touch
[in
the infotainment display and then
touch CHARGING at the bottom of
the display.
The Charge Start and Charge
Complete time estimates are also
displayed on the screen. These
estimates are most accurate when the
vehicle is plugged in and in moderate
temperature conditions. Also, to get
an accurate time estimate, the vehicle
uses an internal clock for
programmable charging, not the clock
in the infotainment display.
Charge Mode Status
Immediately : The vehicle starts
charging as soon as it is connected to
an electrical outlet. See Plug-In
Charging (PLUG-IN Only) 0274.
Delay Charge Based on Departure
Time : The vehicle estimates the
charging start time considering the
programmed departure time for the
current day of the week. Charging
begins at the start time and is
complete by the departure time only if
sufficient time is allowed after the
charge cord is plugged in.

154 INSTRUMENTS AND CONTROLS
Delay (Electric Rate and Departure
Time) :The vehicle estimates the
charging start time based on the
utility rate schedule, utility rate
preference, and the programmed
departure time for the current day of
the week. The vehicle will charge
during the least expensive rate periods
to achieve a full battery charge by the
departure time. Electrical rate
information from the utility company
for the charging location is required
for this mode.
Also, if the selected electric rate
settings result in a very long charge
completion time, the vehicle will start
charging immediately upon plug-in.
For example, if the electric rate table
is set up with all “Peak”rates and the
rate preference is to charge during “Off-Peak”
rates only, then the vehicle
will start charging immediately upon
plug-in.
Charge Limit Selection
The Charge Limit Preference setting
allows the customer to select their
vehicle’s charge level so it matches the
capability of their charging location.
If the vehicle consistently stops
charging after plugging in, or if a
circuit breaker continues to trip,
reducing to a lower Charge Limit
Preference may resolve the issue.
The Charge Limit Preference should be
configured to match the electrical
current rating for the electrical outlet
that the charge cord is connected to.
The Charge Limit Preference
settings are: .
Maximum: Limits AC current to
12 amps
. Reduced: Limits AC current to
8 amps
Exact current levels may vary from
the values shown in this manual.
Check the vehicle for the current
available levels.
The Charge Limit Preference setting
can be changed at any time while the
infotainment display is operable.
For some vehicles, the Charge Limit
Preference must be updated prior to
the vehicle being charged and the
Charge Limit Preference will reset to a
default value when the vehicle is
shifted from P (Park).
