INSTRUMENTS AND CONTROLS 127
English
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.
Engine Oil Temperature
Gauge (Performance
Configuration Only)
Metric
English
This gauge shows the engine oil
temperature.
If the gauge pointer moves into the
high end, it means that the engine oil
has overheated. If the vehicle has been
operated under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible.
See Engine Oil 0244.

and it may not be covered by the
vehicle warranty. SeeEngine
Overheating 0253.
The engine coolant temperature
warning light comes on when the
engine has overheated.
If this happens pull over and turn off
the engine as soon as possible. See
Engine Overheating 0253.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information about
tire pressures and the TPMS. When the Light Is On Steady
This indicates that one or more of the
tires are significantly underinflated.
A Driver Information Center (DIC) tire
pressure message may also display.
Stop as soon as possible, and inflate
the tires to the pressure value shown
on the Tire and Loading Information
label. See
Tire Pressure 0279.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light will
come on at every ignition cycle. See
Tire Pressure Monitor Operation 0282.
Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
(Continued)
Caution (Continued)
The repairs would not be covered
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.
This light should come on briefly as
the engine 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
the engine properly. The vehicle could
be low on oil and might have some
other system problem. See your dealer.

Oil Life :Shows an estimate of the
oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low, the
CHANGE ENGINE OIL SOON message
will appear on the display. The oil
should be changed as soon as
possible. See Engine Oil0244. In
addition to the engine oil life system
monitoring the oil life, additional
maintenance is recommended. See
Maintenance Schedule 0322.
The Oil Life display must be reset
after each oil change. It will not reset
itself. Do not reset the Oil Life display
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until the
next oil change. To reset the engine
oil life system, press and hold SEL for
several seconds while the Oil Life
display is active. See Engine Oil Life
System 0246.
Tire Pressure : Shows the
approximate pressures of all four tires.
Tire pressure is displayed in either
kilopascal (kPa) or in pounds per square inch (psi). If the pressure is
low, the value for that tire is shown in
amber.
See
Tire Pressure Monitor System 0281
and Tire Pressure Monitor Operation

Head-Up Display (HUD)
{Warning
If the HUD image is too bright or
too high in your field of view, it
may take you more time to see
things you need to see when it is
dark outside. Be sure to keep the
HUD image dim and placed low in
your field of view.
If equipped with HUD, some
information concerning the operation
of the vehicle is projected onto the
windshield. The image is projected through the HUD lens on top of the
instrument panel. The information
appears as an image focused out
toward the front of the vehicle.
Caution
If you try to use the HUD image as
a parking aid, you may misjudge
the distance and damage your
vehicle. Do not use the HUD image
as a parking aid.
The HUD information can be
displayed in various languages. The
speedometer reading and other
numerical values can be displayed in
either English or metric units.
The language selection is changed
through the radio and the units of
measurement is changed through the
instrument cluster. See “Settings”in
the Infotainment Manual and
“Options” underInstrument Cluster
