2007 PONTIAC GRAND PRIX engine

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
the vehicle needs more power for passing, and it is:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator pedal all the way down.
The vehicle will shift down to the next gear and
have more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 301.
Notice:If your vehicle seems to start up
rather slowly or not shift gears when you go
faster, and you continue to drive your vehicle
that way, you could damage the transaxle.
Have your vehicle serviced right away. You can
drive in SECOND (2) when you are driving
less than 35 mph (55 km/h) and DRIVE (D) for
higher speeds until then.THIRD (3):This position is also used for normal
driving. However, it reduces vehicle speed more
than DRIVE (D) without using your brakes. You
might choose THIRD (3) instead of DRIVE (D)
when driving on hilly, winding roads, when towing a
trailer, so there is less shifting between gears, when
going down a steep hill and when driving on
non-highway scenarios (i.e. city streets etc.).
SECOND (2):This position reduces vehicle speed
even more than THIRD (3) without using your
brakes. You can use SECOND (2) on hills. It can
help control the vehicle’s speed as it goes
down steep mountain roads, but then you would
also want to use the brakes off and on.
Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph
(90 km/h), can cause damage to your engine
and/or transaxle. Also, shifting into SECOND (2)
at speeds above 65 mph (105 km/h) can cause
damage. Drive in DRIVE (D) instead of
SECOND (2).
112

FIRST (1):This position reduces vehicle speed
even more than SECOND (2) without using
your brakes. It can be used on very steep hills, or
in deep snow or mud. If the shift lever is moved
to FIRST (1), while the vehicle is moving forward,
the transaxle will not shift into rst gear until
the vehicle is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle.
If you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.
Performance Shifting with TAP-Shift®
If the vehicle is equipped with the 3800 V6
Supercharged engine or the 5.3L V8 engine, your
vehicle may have this feature. It allows you to
change gears similar to a manual transaxle.
To fully use this feature, do the following:
1. The MANUAL (M) position can be selected
while the vehicle is moving. The current
transaxle position will continue to be displayed
on the Driver Information Center (DIC) and
Head-Up Display (HUD), if equipped.2. Move the shift lever
to the MANUAL (M).
3. The paddles are
located on the
steering wheel.
They are used to
up-shift or down-shift
the transaxle.
113

4. Push either paddle once to up-shift to the next
gear. Pull either paddle once to down-shift to
the next gear.
The vehicle will begin moving in rst gear upon
acceleration. For better control in icy or slippery
conditions, the vehicle may start out in
SECOND (2), rather than FIRST (1). This
will only occur if you have “tapped up” to
second gear.
The up-shift light on the
instrument panel cluster,
or the up-shift symbol on
the HUD, if equipped, is
given as a prompt to use
the TAP-Shift
®paddle.
For more information, seeUp-Shift Light on
page 175.
The up-shift light will only appear in the instrument
panel cluster if the HUD is off or if the vehicle
does not have HUD.This prompt to up-shift, as needed, will be given
throughout acceleration. If up-shifting does not
occur when prompted, the vehicle speed will be
limited to protect the engine.
The gear position will display on the DIC and
HUD, if equipped, when in manual mode.
Pressing the accelerator while driving in the
highest gear (FOURTH (4)) between 20 mph
(32 km/h) and 50 mph (80 km/h), will make
the transaxle automatically downshift. As your
speed gets closer to 50 mph (80 km/h), you
will need to increase accelerator pedal travel to
get the vehicle to downshift. At 50 mph (80 km/h),
even with the accelerator fully depressed, the
transaxle will always remain in FOURTH (4). The
transaxle will also automatically downshift as
the vehicle decelerates and comes to a stop.
If a paddle is pushed or pulled and the vehicle
cannot respond to a transaxle gear change,
a chime will sound. The system will not allow either
an up-shift or a down-shift if the vehicle speed
is too fast or too slow, nor will it allow a start from
THIRD (3) or higher gear.

Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
Your vehicle can roll. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move, even
when you are on fairly level ground, use
the steps that follow. If you are pulling a
trailer, seeTowing a Trailer on page 324.
1. Hold the brake pedal down with your right foot
and set the parking brake.
2. Move the shift lever into PARK (P) by holding
in the button on the shift lever and pushing
the shift lever all the way toward the front
of the vehicle.
3. Turn the ignition key to OFF.
4. Remove the key and take it with you. If you
can leave your vehicle with the ignition key in
your hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle
could move suddenly if the shift lever is
not fully in PARK (P) with the parking
brake rmly set. And, if you leave the
vehicle with the engine running, it could
overheat and even catch re. You or
others could be injured. Do not leave your
vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and
your parking brake is rmly set before you leave it.
After you have moved the shift lever into PARK (P),
hold the regular brake pedal down. Then, see if you
can move the shift lever away from PARK (P)
without rst pushing the button.
If you can, it means that the shift lever was not
fully locked in PARK (P).

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the
gas carbon monoxide (CO), which you
cannot see or smell. It can cause
unconsciousness and death.
You might have exhaust coming in if:
Your exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a
collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when
driving over high points on the road
or over road debris.
Repairs were not done correctly.
Your vehicle or exhaust system has
been modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows
down to blow out any CO; and
Have your vehicle xed immediately.
119

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 119.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 311.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your vehicle when the engine is running
unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
always set your parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 116.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 324.
