■Driving range
■ Average fuel consumption
■ Average fuel consumption after refueling
■ Current fuel consumption
■ Average vehicle speed Displays the estimated maximum distance that can
be driven with the quantity of fuel remaining.
This distance is computed based on your average fuel
consumption. As a result, the actual distance that can be
driven may differ from that displayed.
Displays the average fuel
consumption since the
function was reset.
The function can be reset by pushing the DISP switch
for longer than one second when the average fuel con-
sumption is displayed.
Displays the average fuel consumption since the
vehicle was last refueled.

■Gear position display
(vehicles with an automatic transmission only)
Indicates the current gear , and the range of gears
that is available when the shift lever is in the S or D
position. the gear range is shown by the number of
dots ( ) and the current gear is shown as a number.
The transmission automatically selects the gears
within the driver selected gear range.
In the illustration to the left, a range of 6 available gears
(1 through 6) has been selected by the driver. (The shift
lever is in the D or S position with 6 ranges enabled) It is
possible for the transmission to automatically select
between all 6 of the gears. In this case, the transmission
has selected third gear.
■System check display
After switching the engine switch to IG -ON mode, CHECK is displayed while sys-
tem operation is checked. When the system check is complete, COMPLETED is
displayed before returning to the normal screen.
CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver's shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in personal
death or injury.

2-3. Operating the lights and windshield wipers
AFS (vehicles with discharge headlights)AFS (Adaptive Front Lighting System) im proves visibility at intersections
and on curves by automatically adjusting the level of the headlights
according to vehicle speed and the degree of the tire angle that are con-
trolled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■ Deactivating AFS
How to switch: P. 214
The indicator turns on when the AFS is deactivated.
■Daytime running light system
To make your vehicle more visible to other drivers, the headlights turn on automati-
cally (at a reduced intensity) whenever the engine is started and the parking brake
is released. Daytime running lights are not designed for use at night.
■Headlight control sensor
■Automatic light off system
The headlights and tail lights turn off 30 seconds after a door is opened or closed if
the engine switch has been switched to ACC or turned OFF while the headlights
are turned on. (The light turns off i mmediately if the button on the key is
pressed after all doors are locked.)
To turn the lights on again, switch to IG-ON mode, or turn the light switch OFF
once and then back to the or position.
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
