Trip/Fuel Menu Items
3: Press this button to scroll through
the following menu items:
Odometer
Press
3until XX km (mi) displays. This
display shows the distance the vehicle has
been driven in either kilometers (km) or
miles (mi).
Trip Odometers
Press
3until A or B displays. This
display shows the current distance traveled
in either kilometers (km) or miles (mi) since
the last reset for each trip odometer. Both
trip odometers can be used at the
same time. Each trip odometer can be reset to zero
separately by pressing
Vwhile the desired
trip odometer is displayed.
The trip odometer has a feature called the
retro-active reset. This can be used to set
the trip odometer to the number of
kilometers (miles) driven since the ignition
was last turned on. This can be used if the
trip odometer is not reset at the beginning
of the trip.
To use the retro-active reset feature, press
and hold
Vfor at least four seconds. The
trip odometer will display the number of
kilometers (km) or miles (mi) driven since
the ignition was last turned on and the
vehicle was moving. Once the vehicle begins
moving, the trip odometer will accumulate
mileage. For example, if the vehicle was
driven 8 km (5 miles) before it is started
again, and then the retro-active reset feature
is activated, the display will show 8 km
(5 miles). As the vehicle begins moving, the
display will then increase to 8.1 km
(5.1 miles), 8.2 km (5.2 miles), etc.
If the retro-active reset feature is activated
after the vehicle is started, but before it
begins moving, the display will show the
number of kilometers (km) or miles (mi) that
were driven during the last ignition cycle.

Fuel Range
Press
3until FUEL RANGE displays. This
display shows the approximate number of
remaining kilometers (km) or miles (mi) the
vehicle can be driven without refueling.
The fuel range estimate is based on an
average of the fuel economy over recent
driving history and the amount of fuel
remaining in the fuel tank. This estimate
will change if driving conditions change. For
example, if driving in traffic and making
frequent stops, this display may read one
number, but if the vehicle is driven on a
freeway, the number may change even
though the same amount of fuel is in the
fuel tank. This is because different driving
conditions produce different fuel economies.
Generally, freeway driving produces better
fuel economy than city driving.
If the vehicle is low on fuel, the FUEL LEVEL
LOW message will be displayed.
Average Economy
Press
3until AVG ECONOMY displays.
This display shows the approximate average
liters per 100 kilometers (L/100 km) or miles

Battery Load Management
The vehicle may have 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 gauge 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 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 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
SERVICE BATTERY CHARGING SYSTEM. If this
messages displays, it is recommended that
the driver reduce the electrical loads as
much as possible.
Battery Power Protection
This feature shuts off the interior lamps if
they are left on for more than 10 minutes
when the ignition is off. This helps to
prevent the battery from running down.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.
