Electric Power Management
This vehicle has Electric Power Management (EPM),
an advanced control system. It estimates the battery's
temperature and state of charge and then adjusts the
voltage for best performance and extended life of the
battery.
When the battery's state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When
the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gauge or voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer loads,
and loads plugged into accessory power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator's output
and the vehicle's electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver.
Battery Run-Down Protection
The vehicle has a battery saver feature designed to
protect the vehicle's battery.
When any interior lamp is left on and the ignition is
turned off, the battery rundown protection system
automatically turns the lamp off after 20 minutes.
This prevents draining of the battery.

Speedometer and Odometer
The speedometer shows the speed in both kilometers
per hour (km/h) and miles per hour (mph).
The vehicle's odometer works together with the Driver
Information Center (DIC). Trip A and Trip B can be set
on the odometer. See“Trip Information”underDIC
Operation and Displays on page 4‑46.
The vehicle does not have to be running to check the
odometer mileage. Simply open the driver's door and
the mileage briefly displays.
If the vehicle ever needs a new odometer installed, the
new one will be set to the correct total mileage of the
old odometer.
Tachometer
The tachometer
displays the engine
speed in revolutions
per minute (rpm).
Notice: If the engine is operated with the
tachometer in the red warning area, the vehicle
could be damaged and the damages would not be
covered by the vehicle warranty. Do not operate the
engine with the tachometer in the red warning area.
4-25

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.
