Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the vehicle is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light then goes off.
If the light comes on and stays on
while driving, the vehicle may have
a problem with the cooling system.
Stop and turn off the vehicle to
avoid damage to the engine.
A warning chime sounds when this
light is on.
SeeEngine Overheating on
page 10‑18 for more information.
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. See Vehicle Messages on
page 5‑37 for more information. Stop as soon as possible, and
inflate the tires to the pressure value
shown on the Tire and Loading
Information label. See
Tire Pressure
on page 10‑44 for more information.
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 on page 10‑46 for more
information.

show 8 km (5 mi). As the vehicle
begins moving, the display will then
increase to 8.2 km (5.1 mi), 8.4 km
(5.2 mi), etc.
If the retroactive 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) driven
during the last ignition cycle.
RANGE
Press the trip/fuel button until
RANGE displays. This display
shows the approximate number of
remaining kilometers (km) or
miles (mi) the vehicle can be driven
without refueling. The display will
show LOW if the fuel level is low.
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. 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. Fuel range cannot be reset.
AVG (Average) ECONOMY
Press the trip/fuel button until 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
the set/reset button.
TIMER
Press the trip/fuel button until
TIMER displays. This display can be
used as a timer.
To start the timer, press the
set/reset button while 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 the
set/reset button briefly while TIMER
is displayed.
To reset the timer to zero, press and
hold the set/reset button while
TIMER is displayed.
