AUTOMATIC OVERDRIVE (D): This position is
for normal driving. If you need more power for passing,
and you're:

Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more,
push the accelerator all the way down.
You'll shift down to the next gear and have more power.
NOTICE:
If your vehicle seems to start up rather slowly,
or if it seems not to shift gears as you go faster,
something may be wrong with a transaxle
system sensor. If you drive very far that way,
your vehicle can be damaged. So, if this happens,
have your vehicle serviced right away. Until then,
you can use SECOND (2) when you are driving
less than 35 mph (55 km/h) and AUTOMATIC
OVERDRIVE (D) for higher speeds.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):

When driving on hilly, winding roads.

When towing a trailer, so there is less shifting
between gears.

When going down a steep hill.

The exterior lamps control has three positions:
(Parking Lamps): Turning the control to this
position turns on the parking lamps, together with
the following:

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights
(Headlamps): Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
AUTO: Turning the control to this position turns the
headlamps, taillamps and parking lamps on and off
automatically, while the ignition is on, by sensing how
dark it is outside. For more information see ªAutomatic
Light Controlº later in this section.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.
The DRL system will make your high
-beam headlamps
come on at a reduced brightness when the following
conditions are met:

The ignition is on,

the exterior lamps control is in AUTO or the parking
lamps only position,

the light sensor detects daytime light,

the parking brake is released, and

the shift lever is not in PARK (P) on vehicles with an
automatic transaxle only.
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps and instrument panel lights will
not be illuminated unless you have turned the exterior
lamps control to the parking lamp position.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-47 Automatic Light Control (ALC)
When it is dark enough outside, your Automatic Light
Control (ALC) will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the top
of the instrument panel under the defroster grill, so be
sure it is not covered which will cause the ALC system
to be on whenever the ignition is on.
The ALC system may also be on when driving through a
parking garage, heavy overcast weather or a tunnel. This
is normal.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the ALC
systems so that driving under bridges or bright overhead
street lights does not affect the system. The DRL and
ALC systems will only be affected when the light sensor
sees a change in lighting lasting longer than this delay.To idle your vehicle with the ALC system off, set the
parking brake while the ignition is off. Then start the
vehicle. The ALC system will stay off until you release
the parking brake.
As with any vehicle, you should turn on the regular
headlamps when you need them.
Headlamps Dim to Park
To turn the headlamps off when it is dark outside, turn
the exterior lamps control to the parking lamp position.
In this position, the parking lamps, sidemarker lamps,
taillamps, license plate lamps and instrument panel
lights will be on, but the headlamps will be off.
To turn on the headlamps along with the other lamps
when it is dark outside, turn the exterior lamps control
to the AUTO or headlamp position.
