Trip 1 or Trip 2 : Shows the current distance
traveled, in either kilometers (km) or
miles (mi), since the trip odometer was last
reset.
If equipped, shows the average fuel
economy since the last reset. This number
reflects only the approximate average fuel
economy that the vehicle has right now,
and will change as driving conditions
change. The average fuel economy can be
displayed as mpg, km/L, or L/100km where
applicable.
If equipped, shows the average speed since
the last reset. This number reflects only the
approximate average speed that the vehicle
has, and will change as driving conditions
change. Average speed can be displayed
as mph or km/h where applicable.

Fuel Information or 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. If equipped,
may also show the instantaneous fuel
economy.
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
0 262. In addition to the engine oil life
system monitoring the oil life, additional
maintenance is recommended in the
Maintenance Schedule. See Maintenance
Schedule 0331.
The Oil Life display must be reset after each
oil change. It will not reset itself. Do not
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 0264. Tire Pressure :
Shows the approximate
pressures of all four tires. Tire pressure is
displayed in either kilopascal (kPa) or in

shown in amber. See Tire Pressure Monitor
System 0294 and
Tire Pressure Monitor Operation 0295.
Air Filter Life : Shows an estimate of the
engine air filter’s remaining useful life and
the state of the system. Engine Air Filter Life
95% means 95% of the current air filter life
remains. Messages will display based on the
engine air filter life and the state of the
system. When the REPLACE AT NEXT OIL
CHANGE message displays, the engine air
filter should be replaced at the time of the
next oil change. When the REPLACE SOON
message displays, the engine air filter
should be replaced at the earliest
convenience.
The Air Filter Life display must be reset after
the engine air filter replacement. To reset,
see Engine Air Filter Life System 0265.
Fuel Economy : The center displays the
approximate instantaneous fuel economy as
a number and bar graph. Displayed above
the bar graph is a running average of fuel
economy for the most recently traveled

Engine Power Messages
ENGINE POWER IS REDUCED
This message displays when the vehicle's
propulsion power is reduced. A reduction in
propulsion power can affect the vehicle's
ability to accelerate. If this message is on,
but there is no observed reduction in
performance, proceed to your destination.
Under certain conditions the performance
may be reduced the next time the vehicle is
driven. The vehicle may be driven while this
message is on, but maximum acceleration
and speed may be reduced. Anytime this
message stays on, or displays repeatedly,
the vehicle should be taken to your dealer
for service as soon as possible. Under certain operating conditions,
propulsion will be disabled. Try restarting
after the ignition has been off for
30 seconds.
Vehicle Speed Messages
SPEED LIMITED TO XXX KM/H (MPH)

118 Lighting
This indicator light turns on in the
instrument cluster when the high-beam
headlamps are on.
Flash-to-Pass
The flash-to-pass feature works with the low
beams or Daytime Running Lamps (DRL) on
or off.
To flash the high beams, pull the turn signal
lever toward you momentarily and then
release it.
Daytime Running Lamps (DRL)
DRL can make it easier for others to see the
front of your vehicle during the day.
The DRL system comes on in daylight when
the following conditions are met:
.The ignition is on.
.The exterior lamp control is in AUTO.
.The light sensor determines it is daytime.When the DRL are on, the taillamps,
sidemarker lamps, instrument panel lights,
and other lamps will not be on. The
instrument cluster will be lit.
The DRL turn off when the ignition is off.
The regular headlamp system should be
turned on when needed.
Automatic Headlamp System
When the exterior lamp control is set to
AUTO and it is dark enough outside, the
headlamps come on automatically.
There is a light sensor on top of the
instrument panel. Do not cover the sensor;
otherwise the headlamps will come on when
they are not needed. The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
When it is bright enough outside, the
headlamps will turn off or may change to
Daytime Running Lamps (DRL).
The automatic headlamp system turns off
when the exterior lamp control is turned to
Oor the ignition is off.
Lights On with Wipers
If the windshield wipers are activated in
daylight with the engine on, and the
exterior lamp control is in AUTO, the
headlamps, parking lamps, and other
exterior lamps come on. The transition time
for the lamps coming on varies based on
wiper speed. When the wipers are not
operating, these lamps turn off. Move the
exterior lamp control to
Oor;to disable
this feature.

(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 of the power
needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, 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 DIC message might bedisplayed and 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 off position
and then back to the parking lamp or
headlamp position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.
