Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transaxle shift lock control system. You must fully apply
your regular brakes before you can shift from PARK (P)
when the ignition is in RUN. If you cannot shift out
of PARK (P), increase pressure on the shift lever by
pushing is all the way in to PARK (P) while keeping the
brake pedal pushed down. Then move the shift lever
out of PARK (P). See
Shifting Out of Park (P) on
page 2-29
Notice:
Shifting to REVERSE (R) while your vehicle
is moving forward could damage your transaxle.
Shift to REVERSE (R) only after your vehicle is
stopped.
REVERSE (R):Use this gear to back up.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transaxle, see If
You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-31.
NEUTRAL (N):In this position, your engine doesn't
connect with the wheels. To restart when you're already
moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
ªracingº (running at high speed) is dangerous.
Unless your foot is ®rmly on the brake pedal,
your vehicle could move very rapidly. You
could lose control and hit people or objects.
Don't shift into a drive gear while your engine
is racing.
Notice:Damage to your transaxle caused by
shifting into a drive gear with the engine racing isn't
covered by your warranty.
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
(
X)for higher speeds.

Daytime Running Lamps/Automatic
Headlamp System
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
®rst sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't covered.
The DRL system will make your front turn signal lamps
come on when the following conditions are met:
·The ignition is on,
·the exterior lamps control is off and
·the parking brake is released.
While the DRL are on, only your front turn signal lamps
will be on. The headlamps, taillamps, sidemarker
and other lamps won't be on. Your instrument panel
won't be lit up either.When it's dark enough outside, your front turn signal
lamps will turn off and your vehicle's headlamps
and parking lamps will turn on. The other lamps that
come on with your headlamps will also come on.
When it's bright enough outside, your headlamps will
go off and your front turn signal lamps will come on.
To idle your vehicle with the DRL and automatic
headlamp control off, set the parking brake while the
ignition is in OFF or LOCK. Then start your vehicle. The
DRL, headlamps and parking lamps will stay off until
you release the parking brake.
To turn off the automatic headlamp feature when it's
dark outside, move the exterior lamps control to
the parking lamp position. Your parking lamps will
remain illuminated and your headlamps will turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Low Oil Level Light
If your vehicle is equipped
with an oil level monitoring
system, the LOW OIL
light will come on brie¯y
when the ignition key
is turned on.
If the light does not come on brie¯y, have it ®xed so it
will be ready to warn you if there's a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. See
Engine Oil on page 5-13.Ifthe
light does not come on brie¯y, have the low oil level
sensor system repaired so it will be ready to warn you if
there's a problem.
The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. It does not monitor engine oil level when
the engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for
a considerable period of time, allowing the oil normally
in circulation to drain back into the oil pan.
Change Engine Oil Light
The CHANGE OIL SOON
light should come on
brie¯y as a bulb check
when you start the engine.
If the light doesn't come
on, have it serviced.
If the CHANGE OIL SOON light comes on and stays on
after you start the engine, have the oil changed.
For additional information, see ªWhen to Change Engine
Oil (GM Oil Life System)º under
Engine Oil on page 5-13.
To reset the CHANGE OIL SOON light, see ªHow to
Reset the Systemº under
Engine Oil on page 5-13.
