ignition CHEVROLET HHR 2010 1.G Service Manual

Fuel Gauge
The fuel gauge indicates
about how much fuel is
left in the fuel tank.
An arrow on the fuel gauge indicates the side of the
vehicle the fuel door is on.
Here are four things that some owners ask about. None
of these show a problem with the fuel gauge:
.At the service station, the gas pump shuts off
before the gauge reads full.
.It takes a little more or less fuel to fill up than the
gauge indicated. For example, the gauge may
have indicated the tank was half full, but it actually
took a little more or less than half the fuel tank's
capacity to fill it.
.The gauge moves a little when the vehicle turns a
corner or speeds up.
.The gauge does not go back to empty when the
ignition is turned off.
For the fuel tank capacity, see Capacities and
Specifications on page 6‑125.
Boost Gauge
United StatesCanada
For vehicles with this gauge, it indicates vacuum during
light to moderate throttle and boost under heavier
throttle.
4-40

This gauge displays the air pressure level in the intake
manifold before it enters the engine's combustion
chamber.
It is automatically centered at zero every time the
engine is started. Actual vacuum or 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.
Reconfigurable Performance
Display (RPD)
For vehicles with the RPD, the screen displays
information that can be used to monitor vehicle
performance. The RPD knob located next to the screen
is used to configure the display and select information
to be viewed.
A short video plays whenever the ignition key is turned
on. Press the RPD knob to stop the video and go
directly to RPD displays.
RPD Screen Example US Version Shown, CanadaSimilar (French Display Currently Not Available)
The RPD screen displays two divided areas (A, B) of
information called Regions. Advance through Region A
screens to show various gauges and speedometer
displays. Advance through Region B screens to show
digital readouts and indicator information.
The position of these regions can be reversed. See the
SETUP MENU for more information.
When the ignition is turned off and then back on, the
RPD shows the last screen displayed.

Region A Gauge and Speedometer
Displays
Change the information displayed in Region A by
turning the knob either clockwise or counterclockwise.
The available gauges are:
BOOST:Displays positive boost pressure as
determined by the manifold air pressure (MAP) sensor.
AIR/FUEL RATIO: Displays the mass ratio of air to fuel.
CAM PHASER ANGLES: Displays orientation of the
intake and exhaust cam shafts relative to their park
positions as commanded by the engine control module.
OVERLAP represents the total distance the intake and
exhaust cam shafts have phased.
SPARK ADVANCE/ KNOCK RETARD: The spark
advance gauge displays ignition timing. Knock retard
indicates the amount of ignition delay to reduce spark
knock.
ENGINE POWER & TORQUE : Displayed engine
power and torque are engine flywheel output values
calculated by the engine control module. These
values are approximate and may change with the air
conditioning load, generator output, air temperature, air
pressure, and fuel octane. SPEEDOMETER & G FORCE :
The G FORCE meter
displays lateral acceleration. While turning right,
G forces are felt on the left, and vice versa. PEAK
values are stored indefinitely, and can be reset with
a press and hold of the RPD knob while viewing the
G FORCE meter.
SETUP MENU: Press the RPD knob to enter this
menu. The vehicle should be stopped while configuring
the setup menu selections.
SCREEN OFF: Turns the screen off.
Region B Readout Displays
Press the RPD knob to highlight Region B. The
information displayed can be changed by turning the
RPD knob either clockwise or counterclockwise.
Press the RPD knob again, to store the selection. The
selection will also be stored after a few seconds of no
activity. Available modes are:
Readouts #1
SHIFT LIGHTS/GEAR INDICATION: The shift lights
provide visual identification of engine speed for a
transmission gear. Shift light minimum and maximum
RPM settings can be viewed and configured in the
SETUP screen. The gear indication on manual
transmission vehicles is calculated by the engine
control module. The gear is only displayed when
enough torque is available to determine the selected
forward gear.
