transmission PONTIAC G5 2008 Owner's Guide

If the ETS indicator/warning light comes on and stays on
for an extended period of time when the transmission
shift lever is in any position other than LOW (L), your
vehicle may need service.
When this light is on solid, the system will not limit wheel
spin. Adjust your driving accordingly.
Check your DIC messaging to determine whether it is
because of the driver turning off the system, or that the
system may not be working properly and your vehicle
requires service. When this light is turned on, either the
SERVICE TRACTION or TRACTION OFF message will
be displayed.
SEE DIC Warnings and Messages for more information
on the messages associated with this light.
To limit wheel spin, especially in slippery road conditions,
you should always leave the ETS on. But you can turn the
system off if you prefer.
To turn the system off, shift to LOW (L) or REVERSE (R).
When you turn the system off, the ETS indicator/warning
light and message will come on and stay on and
TRACTION OFF message will be displayed when the
gear shift is in LOW (L). The indicator/warning light and
message will not come on when the gear shift is in
REVERSE (R). If the ETS is limiting wheel spin when
you shift to LOW (L) or REVERSE (R) to turn the system
off, the indicator/warning light will come on in LOW (L).
But the system won’t turn off right away. It will wait until
there’s no longer a current need to limit wheel spin.See DIC Warning and Messages for more information on
the messages associated with this light.
You can turn the system back on at any time by shifting to
AUTOMATIC OVERDRIVE (D) or INTERMEDIATE (I).
The ETS indicator/warning light should go off.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
Electronic Stability Control (ESC)
Your vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the driver
maintain directional control of the vehicle in most
driving conditions.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to ensure
there are no problems. You may hear or feel the system
working. This is normal and does not mean there is a
problem with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h).
If the system fails to turn on or activate, the ESC/TCS
light comes on, and the ESC OFF and/or SERVICE ESC
message displays.

Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep your vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
{CAUTION:
If you do not shift down, the brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let the engine assist the brakes on a steep
downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. The brakes will have
to do all the work of slowing down and they
could get so hot that they would not work well.
You would then have poor braking or even
none going down a hill. You could crash.
Always have the engine running and your
vehicle in gear when you go downhill.
Stay in your own lane. Do not swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
Top of hills: Be alert — something could be in your
lane (stalled car, accident).
Pay attention to special road signs (falling rocks
area, winding roads, long grades, passing or
no-passing zones) and take appropriate action.

If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free your
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 4-24.
If your vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to your vehicle’s traction
system in the Index. If the stuck condition is too severe
for the traction system to free the vehicle, turn the
traction system off and use the rocking method.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or others
could be injured. The vehicle can overheat,
causing an engine compartment re or other
damage. Spin the wheels as little as possible
and avoid going above 35 mph (55 km/h) as
shown on the speedometer.
For information about using tire chains on your vehicle,
seeTire Chains on page 5-70.
Rocking Your Vehicle to Get It Out
First, turn the steering wheel left and right to clear the
area around the front wheels. Then shift back and forth
between REVERSE (R) and a forward gear, or with a
manual transmission, between FIRST (1) or SECOND (2)
and REVERSE (R), spinning the wheels as little as
possible. To prevent transmission wear, wait until the
wheels stop spinning before shifting gears. Release the
accelerator pedal while you shift, and press lightly on the
accelerator pedal when the transmission is in gear.
By slowly spinning the wheels in the forward and reverse
directions, you will cause a rocking motion that could free
your vehicle. If that does not get your vehicle out after a
few tries, it might need to be towed out. If your vehicle
does need to be towed out, seeTowing Your Vehicle on
page 4-30.

The Tire and Loading Information label also shows
the tire size of the original equipment tires (C) and
the recommended cold tire ination pressures (D).
For more information on tires and ination seeTires
on page 5-48andInflation - Tire Pressure on
page 5-55.
There is also important loading information on the
Certication label. It tells you the Gross Vehicle
Weight Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axle; see
“Certication Label” later in this section.
Steps for Determining Correct Load Limit
1.Locate the statement “The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle placard.
2.Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4.The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400−750 (5 x 150) = 650 lbs).
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
6.If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity of your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer (Manual Transmission) on page 4-32
orTowing a Trailer (Automatic Transmission)
on page 4-32for important information on
towing a trailer, towing safety rules, and
trailering tips.

Dinghy Towing
You may dinghy tow your vehicle from the front following
these steps:
1. Set the parking brake.
2. Turn the ignition key to ACC/ACCESSORY to
unlock the steering wheel.
3. Shift an automatic transmission to NEUTRAL (N) or
a manual transmission to NEUTRAL.
4. Release the parking brake.
To prevent the battery from draining while the vehicle is
being towed, remove the following fuse from the oor
console fuse block: 8 (Ignition Switch, PASS-Key
®III+).
SeeFloor Console Fuse Block on page 5-97for more
information.Remember to reinstall the fuse once you have reached
your destination.
Notice:If you exceed 65 mph (105 km/h) while
towing your vehicle, it could be damaged. Never
exceed 65 mph (105 km/h) while towing your vehicle.
‘
Notice:Towing your vehicle from the rear could
damage it. Also, repairs would not be covered by
the warranty. Never have your vehicle towed from
the rear.
4-31

Dolly Towing
Your vehicle cannot be dolly towed, but can be dinghy
towed. See “Dinghy Towing” earlier in this section.
Notice:Dolly towing your vehicle may cause
damage because of reduced ground clearance.
Always tow your vehicle using the dinghy towing
procedure listed in this section or put your vehicle
on a atbed truck.
Towing a Trailer
(Manual Transmission)
Do not tow a trailer if your vehicle is equipped with a
manual transmission.
Towing a Trailer
(Automatic Transmission)
{CAUTION:
If you do not use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well — or even
at all. You and your passengers could be
seriously injured. You may also damage your
vehicle; the resulting repairs would not be
covered by your warranty. Pull a trailer only if
you have followed all the steps in this section.
Ask your dealer/retailer for advice and
information about towing a trailer with your
vehicle.
Your vehicle can tow a trailer if it is equipped with an
automatic transmission and the proper trailer towing
equipment. If your vehicle is not equipped as stated
previously, do not tow a trailer. To identify the trailering
capacity of your vehicle, you should read the information
in “Weight of the Trailer” that appears later in this section.
4-32

Trailering is different than just driving your vehicle by
itself. Trailering means changes in handling, acceleration,
braking, durability and fuel economy. Successful, safe
trailering takes correct equipment, and it has to be used
properly.
That is the reason for this part. In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull a trailer.
Load-pulling components such as the engine,
transmission, wheel assemblies and tires are forced to
work harder against the drag of the added weight.
The engine is required to operate at relatively higher
speeds and under greater loads, generating extra heat.
Also, the trailer adds considerably to wind resistance,
increasing the pulling requirements.
If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you will be driving. A good source for this
information can be state or provincial police.
Consider using a sway control. You can ask a hitch
dealer about sway controls.
Do not tow a trailer at all during the rst 1,000 miles
(1 600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the rst 500 miles (800 km) that you tow
a trailer, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps your engine
and other parts of your vehicle wear in at the
heavier loads.
Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted speed
for trailers, or no more than 55 mph (90 km/h), to
save wear on your vehicle’s parts.
Do not tow when the outside air temperature is
above 100°F (38°C).
Do not tow more than 1,000 miles (1 600 km)
per year.
Three important considerations have to do with weight:
The weight of the trailer
The weight of the trailer tongue
The total weight on your vehicle’s tires
4-33

Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with
the vehicle. Your vehicle could be damaged.
Avoid making very sharp turns while trailering.
When you are turning with a trailer, make wider turns
than normal. Do this so your trailer will not strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring. Check
with your dealer/retailer. The arrows on your instrument
panel will ash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
ash, telling other drivers you are about to turn, change
lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It is
important to check occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher than
normal engine and transmission temperatures may
result and damage your vehicle. Frequent stops are
very important to allow the engine and transmission
to cool.
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to reduce
engine load. SeeEngine Overheating on page 5-22.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your vehicle may
experience more transmission shifting. A COOLING
MODE ON message may also appear in the DIC.
This alerts the driver that the shifting mode is in progress
and is aiding engine cooling. SeeDIC Warnings and
Messages on page 3-44DIC Warnings and Messages
for more information.

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 you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) for an automatic transmission, or into
gear for a manual transmission. When parking
uphill, turn your wheels away from the curb. When
parking downhill, turn your wheels into the curb.
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 your
parking brake, and then shift into PARK (P) for
an automatic transmission or REVERSE (R) for a
manual transmission.
5. Release the regular brakes.
4-38

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you are
pulling a trailer. SeeScheduled Maintenance on
page 6-4for more on this. Things that are especially
important in trailer operation are automatic transmission
uid (do not overll), engine oil, drive belt, cooling system
and brake system.
Each of these is covered in this manual, and the Index
will help you nd them quickly. If you are trailering,
it is a good idea to review this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-22.
