English Uplevel
When the ignition is on, the fuel gauge
indicates about how much fuel is left in
the tank.
An arrow on the fuel gauge indicates the
side of the vehicle the fuel door is on.
When the indicator nears empty, the low
fuel light comes on. There is a small amount
of fuel left, but the fuel tank should be
filled soon.
Here are three things that some owners ask
about. None of these show a problem with
the fuel gauge:
.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 tank's capacity
to fill the tank.
.The gauge moves a little while turning a
corner, speeding up or braking.
.The gauge takes a few seconds to
stabilize after the ignition is turned on
and goes back to empty when the
ignition is turned off.
Engine Oil Temperature Gauge
Metric
English
This gauge shows the engine oil
temperature.
If the gauge pointer moves into the high
end, it means that the engine oil has
overheated. If the vehicle has been operated
under normal driving conditions, pull off the
road, stop the vehicle, and turn off the
engine as soon as possible.
See Engine Oil 0276.

If this happens, pull over and turn off the
engine as soon as possible. SeeEngine
Overheating 0285.
Tire Pressure Light
For vehicles with the Tire Pressure Monitor
System (TPMS), this light comes on briefly
when the engine is started. It provides
information about tire pressures and
the TPMS.
When the Light Is On Steady
This indicates that one or more of the tires
are significantly underinflated.
A Driver Information Center (DIC) tire
pressure message may also display. Stop as
soon as possible, and inflate the tires to the
pressure value shown on the Tire and
Loading Information label. See Tire Pressure
0 307. When the Light Flashes First and Then Is On
Steady
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 at every ignition
cycle. See
Tire Pressure Monitor Operation
0 310.
Engine Oil Pressure Light
Oil pressure can vary with engine speed,
outside temperature, and oil viscosity.
On some models, the oil pump will vary
engine oil pressure according to engine
needs. Oil pressure may change quickly as
the engine speed or load varies. This is
normal. If the oil pressure warning light or
Driver Information Center (DIC) message
indicates oil pressure outside the normal
operating range, check the vehicle's oil as
soon as possible.
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
(Continued)
Caution (Continued)
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.
This light should come on briefly as the
engine is started. If it does not come on,
have the vehicle serviced by your dealer.
If the light comes on and stays on, it means
that oil is not flowing through the engine
properly. The vehicle could be low on oil
and might have some other system
problem. See your dealer.

DIC Info Pages
The following is the list of all possible DIC
info page displays. Some may not be
available for your particular vehicle. Some
items may not be turned on by default but
can be turned on through the Options app.
See “DIC Info Page Options” earlier in this
section.
Speed : Shows the vehicle speed in either
kilometers per hour (km/h) or miles per
hour (mph). A speed limit sign can also be
shown, if equipped.
Trip A or Trip B : Shows the current distance
traveled, in either kilometers (km) or
miles (mi), since the trip odometer was last
reset. This also 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. This number reflects only the
approximate average fuel economy that the
vehicle has right now, and will change as
driving conditions change.
Press and hold
Vwhile this display is active
to reset the trip odometer and the average
fuel economy. Trip A and Trip B can also be
reset by pressing
pand choosing reset.
Fuel Range : Shows the approximate
distance the vehicle can be driven without
refueling. LOW will be displayed when the
vehicle is low on fuel. The fuel range
estimate is based on an average of the
vehicle's fuel economy over recent driving
history and the amount of fuel remaining in
the fuel tank.
Remaining Oil Life : Shows an estimate of
the oil's remaining useful life. If REMAINING
OIL LIFE 99% is displayed, that means 99%
of the current oil life remains.
When the remaining oil life is low, the
CHANGE ENGINE OIL SOON message will
appear on the display. The oil should be changed as soon as possible. See
Engine Oil
0 276. In addition to the engine oil life
system monitoring the oil life, additional
maintenance is recommended in the
Maintenance Schedule. See Maintenance
Schedule 0346.
The Oil Life display must be reset after each
oil change. It will not reset itself. Do not to
reset the Oil Life display at any time other
than when the oil has just been changed.
It cannot be reset accurately until the next
oil change. To reset, see Engine Oil Life
System 0278.
Tire Pressure : Shows the approximate
pressures of all four tires. Tire pressure is
displayed in either kilopascal (kPa) or in
pounds per square inch (psi). If the pressure
is low, the value for that tire is shown in
amber. See Tire Pressure Monitor System
0 309 and
Tire Pressure Monitor Operation 0310.
Average Vehicle Speed : Displays the
average vehicle speed of the vehicle in
kilometers per hour (km/h) or miles per
hour (mph). This average is based on the
various vehicle speeds recorded since the
last reset. Reset the average speed by
pressing
Vwhen it is displayed.
