Instruments and Controls 73
English
When the ignition is on, the fuel gauge
indicates the approximate amount of fuel
left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the fuel
door is on.
When the indicator nears empty, the low
fuel light comes on. There still is a little fuel
left, but the vehicle should be refueled soon.
The fuel gauge may:
.Take a little more, or less fuel to fill up
than it indicates. For example, the gauge
may have indicated the tank is half full, but it actually will take a little more,
or less than half the tank's capacity to fill
the tank.
.Moves a little while turning a corner,
speeding up, or braking.
.Take a few seconds to stabilize after the
ignition is turned on and goes back to
empty when the ignition is turned off.
These are normal conditions, none of which
indicate a problem with the fuel gauge.
Engine Oil Pressure Gauge
Metric
English
The oil pressure gauge shows the engine oil
pressure in psi (pounds per square inch)
or kPa (kilopascals) when the engine is
running.
Oil pressure may vary with engine speed,
outside temperature and oil viscosity, but
readings above the low pressure zone
indicate the normal operating range.
A reading in the low pressure zone may be
caused by a dangerously low oil level or
other problem causing low oil pressure.

Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. 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.
Engine Coolant Temperature
Gauge
Metric
EnglishThis gauge shows the engine coolant
temperature.
It also provides an indicator of how hard the
vehicle is working. During a majority of the
operation, the gauge will read 100 °C (210 °F)
or less. If the vehicle is pulling a load or
going up hills, it is normal for the
temperature to fluctuate and approach the
122 °C (250 °F) mark. If the gauge reaches
the 125 °C (260 °F) mark, it indicates that the
cooling system is working beyond its
capacity.

Engine Overheating 0186.

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 every time the
vehicle is started. See Tire Pressure Monitor
Operation 0210.
Engine Oil Pressure Light
Caution
Driving the vehicle with low engine oil
pressure can damage the engine and the
repairs would not be covered by the
vehicle warranty.
If the engine oil pressure light comes on
while driving:
1. Stop in a safe location and turn off the engine.
2. Check the oil level. See Engine Oil
0 179.
(Continued)
Caution (Continued)
3. Add oil if the oil level is below the
normal operating range.
4. Restart the vehicle. If the engine oil pressure light stays on for more
than 10 seconds, turn the vehicle
back off. Do not restart the vehicle.
See your dealer for service.
This light should come on briefly when the
engine starts. When the engine is off and
the vehicle is on, the light should remain
illuminated. If it does not come on under
either condition, contact your dealer.
If the light comes on and stays on when the
engine is running, it may not have adequate
oil pressure. The oil level may be low or
there may be some other oil system
problem. Turn the engine off when it is safe
to do so and contact your dealer.
Low Fuel Warning Light
English Shown, Metric Similar
A Low Fuel Warning Light near the fuel
gauge comes on briefly when the ignition is
turned on as a check to show it is working.
It also comes on, and a chime sounds when
the fuel gauge indicator nears empty. The
light turns off when fuel is added. If it does
not, have the vehicle serviced.

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.

84 Instruments and Controls
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
per gallon (mpg). This number is calculated
based on the number of L/100 km (mpg) recorded since the last time this menu item
was reset. To reset AVG ECONOMY, press
and hold
V. The display will return to zero.
Fuel Used
Press
3until FUEL USED displays. This
display shows the number of liters (L) or
gallons (gal) of fuel used since the last reset
of this menu item. To reset the fuel used
information, press and hold
Vwhile FUEL
USED is displayed.
Timer
Press
3until TIMER displays. This
display can be used as a timer.
To start the timer, press
Vwhile TIMER is
displayed. The display will show the amount
of time that has passed since the timer was
last reset, not including time the ignition is
off. Time will continue to be counted as
long as the ignition is on, even if another
display is being shown on the DIC. The
timer will record up to 99 hours, 59 minutes
and 59 seconds (99:59:59) after which the
display will return to zero.
To stop the timer, press
Vbriefly while
TIMER is displayed. To reset the timer to zero, press and hold
V
while TIMER is displayed.
Average Speed
Press
3until AVERAGE SPEED displays.
This display shows the average speed of the
vehicle in kilometers per hour (km/h) or
miles per hour (mph). This average is
calculated based on the various vehicle
speeds recorded since the last reset of this
value. To reset the value, press and hold
V.
The display will return to zero.

Remember, you must reset the OIL LIFE
yourself after each oil change. It will not
reset itself. Also, be careful not to reset the
OIL LIFE 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, see Engine Oil Life System 0181.
