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.
SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
NOTICE:
Don't drive in SECOND (2) for more than 25 miles
(40 km), or at speeds over 55 mph (90 km/h), or
you can damage your transaxle. Use AUTOMATIC
OVERDRIVE (D) or THIRD (3) as much as
possible. Don't shift into SECOND (2) unless you
are going slower than 65 mph (105 km/h) or you
can damage your engine.

See ªTurn Signal/Multifunction Leverº in the Index.
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 lights 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 headlamp switch 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 headlamp
control to the parking lamp position.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
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.

2-46
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
headlamp system when you need it.
Headlamps Dim to Park (If Equipped)
To turn the headlamps off when it is dark outside, turn
the headlamp 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 headlamp control to the
AUTO or headlamp position.
Delayed Headlamps
The delayed headlamps feature will continue to
illuminate the headlamps for 20 seconds after the key is
turned to OFF, then the headlamps will automatically
turn off.
To override the 20 second delayed headlamp feature
while it is active turn the turn signal/multifunction lever
up one position and then back to AUTO.
Fog Lamps (If Equipped)
The button for your fog lamps is located on the
instrument panel, to the left of the steering wheel, beside
the instrument panel intensity control.
When using the fog lamps, the ignition must be on as
well as the parking lamps or the low
-beam headlamps.
Push the button to turn the fog lamps on. An indicator
light on the button will glow when the fog lamps are on.
Push the button again to turn the fog lamps off.
The fog lamps will turn off whenever the high
-beam
headlamps are turned on. When the high beams are
turned off, the fog lamps will come on again.
