{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push
or might go closer to the floor. It can
take longer to stop. If the light is still
on, have the vehicle towed for
service. See Towing the Vehicle on
page 10‑83.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine 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 ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes. If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light on
page 5‑21.
For vehicles with a Driver
Information Center (DIC), see Brake
System Messages on page 5‑35 for
all brake‐related DIC messages.

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. SeeTire Messages on
page 5‑42. 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 10‑50.
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 10‑52.Engine Oil Pressure Light
Notice: 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.
This light comes on briefly while
starting the engine. 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, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and it might
have some other system problem.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Low Fuel Warning Light
This light, under the fuel gauge,
comes on briefly while the engine is
being started.
This light and a chime come on
when the fuel tank is low on fuel.
The Driver Information Center also
displays a FUEL LEVEL LOW
message. See

The trip odometer can be reset to
zero by pressing the set/reset
button while the trip odometer is
displayed. You can also reset the
trip odometer while it is displayed by
pressing and holding the trip
odometer reset stem.
The trip odometer has a feature
called the retroactive 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 retroactive reset feature,
press and hold the set/reset button
for 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 mi) before it is started
again, and then the retroactive reset
feature is activated, the display willshow 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.
Fuel Range
Press the trip/fuel button until FUEL
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.
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.
Fuel Used
Press the trip/fuel button until 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 the set/reset button while FUEL
USED is displayed.

Speedometer
The speedometer shows how fast
the vehicle is moving in either
kilometers per hour (km/h) or miles
per hour (mph). The speedometer
cannot be reset.
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.
Transmission Temperature
Press the trip/fuel button until
TRANS TEMP displays. This
display shows the temperature of
the automatic transmission fluid in
either degrees Celsius (°C) or
degrees Fahrenheit (°F).
Instantaneous Economy and
Active Fuel Management™
Indicator
If your vehicle has this display,
press the trip/fuel button until INST
ECON V8 displays. This display
shows the current fuel economy at a
particular moment and will change
frequently as driving conditions
change. This display shows the
instantaneous fuel economy in liters
per 100 kilometers (L/100 km) or
miles per gallon (mpg). Unlike
average economy, this screen
cannot be reset.
An Active Fuel Management
indicator will display on the right
side of the DIC, while INST ECON
displays on the left side. Active Fuel
Management allows the engine to
operate on either four or eight
cylinders, depending on your driving
demands. When Active Fuel
Management is active, V4 will
display on the DIC. When Active
Fuel Management is inactive, V8
will display. See
