2007 PONTIAC GRAND PRIX ABS

But wet ice can be even more trouble because it
may offer the least traction of all. You can get
wet ice when it is about freezing, 32°F (0°C), and
freezing rain begins to fall. Try to avoid driving
on wet ice until salt and sand crews can get there.
Whatever the condition — smooth ice, packed,
blowing, or loose snow — drive with caution.
If you have the Traction Control System (TCS) or
the Enhanced Traction System (ETS), it will
improve your ability to accelerate when driving on
a slippery road. Even though your vehicle has a
traction system you will want to slow down and
adjust your driving to the road conditions. Under
certain conditions, you may want to turn the TCS or
ETS off, such as when driving through deep snow
and loose gravel, to help maintain vehicle motion at
lower speeds. SeeTraction Control System (TCS)
on page 292orEnhanced Traction System (ETS)
on page 293.
If you do not have TCS or ETS, accelerate gently.
Try not to break the fragile traction. If you
accelerate too fast, the drive wheels will spin and
polish the surface under the tires even more.
Unless you have the Anti-Lock Brake System
(ABS), you will want to brake very gently, too.If you do have ABS, seeAnti-Lock Brake System
(ABS) on page 289. This system improves your
vehicle’s stability when you make a hard stop on a
slippery road. Whether you have ABS or not, you
will want to begin stopping sooner than you would
on dry pavement. Without ABS, if you feel your
vehicle begin to slide, let up on the brakes a little.
Push the brake pedal down steadily to get the most
traction you can.
Remember, unless you have ABS, if you brake so
hard that your wheels stop rolling, you will just
slide. Brake so your wheels always keep rolling
and you can still steer.
Whatever your braking system, allow greater
following distance on any slippery road.
Watch for slippery spots. The road might be
ne until you hit a spot that is covered with ice.
On an otherwise clear road, ice patches may
appear in shaded areas where the sun cannot
reach, such as around clumps of trees, behind
buildings, or under bridges. Sometimes the
surface of a curve or an overpass may remain
icy when the surrounding roads are clear. If you
see a patch of ice ahead of you, brake before
you are on it. Try not to brake while you are
actually on the ice, and avoid sudden steering
maneuvers.

Driving On Grades
Reduce speed and shift to a lower gear before
starting down a long or steep downgrade. If
the vehicle is not shifted down, the brakes may
have to be used so much that they would get hot
and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to
reduce the possibility of engine and transaxle
overheating.
If the vehicle has overdrive, it may be driven in
THIRD (3) instead of DRIVE (D).
Parking on Hills
{CAUTION:
You really should not park your vehicle,
with a trailer attached, on a hill. If
something goes wrong, your rig could
start to move. People can be injured, and
both your vehicle and the trailer can be
damaged.
But if the rig ever has to be parked on a hill, here
is how to do it:
1. Apply the regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release
the regular brakes until the chocks absorb
the load.
4. Reapply the regular brakes. Then apply the
parking brake, and then shift to PARK (P).
5. Release the regular brakes.

How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter, remove the lter
from the vehicle and lightly shake the lter to
release loose dust and dirt. If the lter remains
caked with dirt, a new lter is required.
To inspect or replace the engine air cleaner/lter
do the following:
1. Lift the lter cover tabs on top of the engine
air cleaner/lter housing.
2. Push the lter cover housing toward the
engine.
3. Pull out the lter.
4. Inspect or replace the engine air cleaner/lter.

5. To reinstall the cover, position the tabs
through the slots on the housing. If your
vehicle has one of the 3800 V6 engines, a
notch on the sides of the lter cover will
indicate the correct engagement.
6. Push the cover tabs on top of the housing to
lock the cover in place.
{CAUTION:
Operating the engine with the air
cleaner/lter off can cause you or others
to be burned. The air cleaner not only
cleans the air; it helps to stop ames if
the engine backres. If it is not there and
the engine backres, you could be
burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.Notice:If the air cleaner/lter is off, a backre
can cause a damaging engine re. And, dirt
can easily get into your engine, which will
damage it. Always have the air cleaner/lter in
place when you are driving.
Automatic Transaxle Fluid
When to Check and Change Automatic
Transaxle Fluid
A good time to check the automatic transaxle uid
level is when the engine oil is changed.
Change the uid and lter at the intervals listed in
Additional Required Services on page 476, and
be sure to use the transaxle uid listed in
Recommended Fluids and Lubricants on page 483.
