Electric Power
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery’s temperature and
state of charge. It 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 bring the charge
back up. When the state of charge is
high, the voltage is lowered
slightly to prevent overcharging. If
the vehicle has a voltmeter gage or
a 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 fastenough 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 are on, such
as: 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. If so, a Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If this message is displayed, it is
recommended that the driver reduce
the electrical loads as much as
possible. SeeDIC Warnings and
Messages on page 3-37.
Battery Run-Down
Protection
This feature shuts off the dome
lamp if it is left on for more
than 20 minutes when the ignition is
in LOCK/OFF. This helps to
prevent the battery from being
drained.
Instrument Panel 3-17

Speedometer and
Odometer
The speedometer shows the speed
in both miles per hour (mph) and
kilometers per hour (km/h).
The odometer shows how far the
vehicle has been driven, in
either miles (used in the United
States) or kilometers (used in
Canada).
The odometer mileage can be
checked without the vehicle running
by pressing the trip information
stem. See “Odometer” underDIC
Operation and Displays on
page 3-34for more information.
If the cluster is replaced the
new one will automatically detect
and update the vehicle’s
accumulated mileage.
Trip Odometer
The vehicle has a trip odometer that
indicates how far the vehicle has
been driven since the trip odometer
was last set to zero.
See “Trip Odometer” underDIC
Operation and Displays on
page 3-34for more information.
Tachometer
The tachometer displays the
engine speed in revolutions per
minute (rpm).
Notice:If the engine is operated
while the tachometer is in the
shaded 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 shaded
warning area.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
When the engine is started, a chime
sounds for several seconds to
remind the driver to fasten their
safety belt, unless it is already
buckled.
The safety belt light comes on and
stays on for several seconds,
then ashes for several more.
This chime and light are repeated if
the driver safety belt remains
unbuckled and the vehicle is in
motion. If the driver safety belt is
already buckled, neither the
chime nor the light comes on.
3-24 Instrument Panel

An arrow on the fuel gage indicates
the side of the vehicle the fuel
door is on.
Here are three things that can
happen but do not indicate a
problem with the fuel gage:
At the gas station, the gas pump
shuts off before the gage
reads full.
It takes a little more or less fuel
to ll up than the gage indicated.
For example, the gage may
have indicated the tank was half
full, but it actually took a little
more or less than half the tank’s
capacity to ll the tank.
The gage moves a little when
turning a corner or speeding up.
When the fuel in the fuel tank is low,
a LOW FUEL message displays
on the Driver Information
Center (DIC). SeeDIC Warnings
and Messages on page 3-37
for more information.
