instrument panel and all applicable
illuminated switches in the vehicle
during headlamp and parklamp
operation.
Move the control to the full upright
position, past detent, to turn on the
interior lamps.
Note:If the battery is disconnected,

installed, the dimmer switch requires re-calibration. Rotate the dimmer
switch from the full dim position to the full Dome/ON position to reset.
This will ensure that your displays are visible under all lighting
conditions
AIMING THE HEADLAMPS
Your vehicle may be equipped with a sealed beam or aerodynamic
headlamp system. Sealed beam headlamps may be aimed in the vertical
(up/down) and the horizontal (left/right) directions using the procedures
following. The aerodynamic headlamps can only be aimed in the vertical
direction (up/down) using the following procedures. The headlamps on
your vehicle are properly aimed at the assembly plant and should not
normally need adjusting.
Vertical and horizontal aim adjustment (sealed beam headlamps)
The headlamps on your vehicle are intended to be aimed using
mechanical aimers. If mechanical aimers are used and the cross-car sight
line is in any way blocked, set the legs of the universal adaptor all to the
same setting, such that the cross-car sight line is no longer blocked, per
the instructions for the brand of mechanical aimer used. You can also
aim the headlamps visually using the procedure below.

Powerfold mirror positions, from left to right: Position 1, Position 2,
Position 3
The powerfold mirrors may be folded forward/rearward manually to any
of the three positions shown and electrically to positions 1 and 2 only. If
a mirror is folded manually forward to position 3, you must manually fold
it back to position 1 or 2 in order for the powerfold function to continue
functioning.
Note:Ten or more switch activations within one minute, or repeated
fold/unfolding of the mirrors while holding the switch rearward during
the full travel may cause the system to disable the fold/unfold function to
protect the motors from overheating. Should this occur, wait
approximately 3
1 2minutes for the system to reset and function to return
to normal.
Note:The powerfold mirrors are designed to operate while the vehicle is
stationary or traveling at moderate speeds. If you attempt to powerfold
the mirrors at high speeds, they may not fully fold forward/rearward -
slow down and powerfold or manually fold the mirrors in order to
complete the fold operation.
If the powerfold mirrors feel loose or fold very easily, it is possible that
the powerfold mechanism is out of sync. The powerfold mechanism gets
out of sync when a mirror is manually folded partially in toward the door,
then electrically powerfolded.
Note:The mirrors willnotbe out of sync if the mirrors are manually
folded all the way in or out and then powerfolded.
In order to re-sync the mirrors, manually fold the mirrors toward the
door until a click is heard. Then press the powerfold switch to
electrically fold the mirrors in then out.

Distance to empty (DTE)
Selecting this function from the
INFO MENU estimates
approximately how far you can drive
with the fuel remaining in your tank
under normal driving conditions.
Remember to turn the ignition off
when refueling to allow this feature to correctly detect the added fuel.
The DTE function will display LOW FUEL LEVEL and sound a chime for
one second when you have approximately 50 miles (80 km) to empty. If
you RESET this warning message, this display and chime will return
within 10 minutes.
DTE is calculated using a running average fuel economy, which is based
on your recent driving history of 500 miles (800 km). This value is not
the same as the average fuel economy display. The running average fuel
economy is reinitialized to a factory default value if the battery is
disconnected.

Average fuel economy (AFE)
Select this function to display your
average fuel economy in miles/gallon
or liters/km.
If you calculate your average fuel
economy by dividing miles traveled
by gallons of fuel used (liters of fuel
used by 100 kilometers traveled), your figure may be different than
displayed for the following reasons:
•Your vehicle was not perfectly level during fill-up
•Differences in the automatic shut-off points on the fuel pumps at
service stations
•Variations in top-off procedure from one fill-up to another
•Rounding of the displayed values to the nearest 0.1 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the SELECT/RESET control switch (press and
hold for 2 seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
