toggle Speed Limit sign on or off.
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.
Press
Vwhile this display is active to show

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
pounds per square inch (psi). If the
pressure is low, the value for that tire is
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.

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.

instrument cluster when the high beams
are on.
There is a sensor near the top center of the
windshield that automatically controls the
system. Keep this area of the windshield
clear of debris to allow for best system
performance. The high-beam headlamps remain on, under
the automatic control, until one of the
following situations occurs:
.The system detects an approaching
vehicle's headlamps.
.The system detects a preceding vehicle's
taillamps.
.The outside light is bright enough that
high-beam headlamps are not required.
.The vehicle's speed drops below 20 km/h
(12 mph).
.The IntelliBeam system is disabled by the
button on the turn signal lever. If this
happens, press
bon the turn signal
lever when the exterior lamp control is in
the AUTO or

fog lamps are turned on.
The high beams may not turn off
automatically if the system cannot detect
another vehicle's lamps because of any of
the following:
.The other vehicle's lamps are missing,
damaged, obstructed from view,
or otherwise undetected.
.The other vehicle's lamps are covered
with dirt, snow, and/or road spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust, smoke,
fog, snow, road spray, mist, or other
airborne obstructions.
.The vehicle's windshield is dirty, cracked,
or obstructed by something that blocks
the view of the light sensor.
.The vehicle is loaded such that the front
end points upward, causing the light
sensor to aim high and not detect
headlamps and taillamps.
.The vehicle is being driven on winding or
hilly roads.
The automatic high-beam headlamps may
need to be disabled if any of the above
conditions exist.
Headlamp High/Low-Beam
Changer
Push the turn signal lever away from you
and release, to turn the high beams on. To

Global Positioning System (GPS)
The position of the vehicle is determined by
using satellite signals, various vehicle
signals, and map data.
At times, other interference such as the
satellite condition, road configuration,
condition of the vehicle, and/or other
circumstances can affect the navigation
system's ability to determine the accurate
position of the vehicle.
The GPS shows the current position of the
vehicle using signals sent by GPS satellites.
When the vehicle is not receiving signals
from the satellites, a symbol appears in the
status bar.
This system might not be available or
interference can occur if any of the
following are true:
.Signals are obstructed by tall buildings,
trees, large trucks, or a tunnel.
.Satellites are being repaired or improved.
For more information if the GPS is not
functioning properly, see Problems with
Route Guidance 0149 and
If the System Needs Service 0149.
Vehicle Positioning
At times, the position of the vehicle on the
map could be inaccurate due to one or more
of the following reasons:
.The road system has changed.
.The vehicle is driving on slippery road
surfaces such as sand, gravel, or snow.
.The vehicle is traveling on winding roads
or long, straight roads.
