transmission CHEVROLET HHR 2009 1.G Owner's Guide

To turn the system off or
on, press and release the
ESC/TCS button located
on the instrument panel.
The DIC displays the appropriate message as described
previously when the button is pressed.
Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses that either of the front wheels are
spinning or beginning to lose traction while driving.
For more information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-48.
Notice:If the wheel(s) of one axle are allowed
to spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, thedifferential could be damaged. The repairs would not
be covered by the vehicle warranty. Reduce engine
power and do not spin the wheel(s) excessively while
these lights and this message are displayed.
Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the drive
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not attempt
to shift when the drive wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the warranty book for additional
information.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, a reduction
in acceleration may be noticed or a noise or vibration
may be heard. This is normal.
If the vehicle is in cruise control while the system
activates, the ESC/TCS light ashes and the cruise
control automatically disengages. The cruise control can
be re-engaged when road conditions allow. SeeCruise
Control on page 3-10.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
4-11

Enhanced Traction System (ETS)
The vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels are spinning
or beginning to lose traction. When this happens, the
system reduces engine power and may also upshift the
transmission to limit wheel spin.
If the vehicle has ETS, there is not an ESC/TCS button
on the instrument panel. To turn the system off, shift
to L (Low) or R (Reverse). There is more information
about how to turn the system off later in this section.
The ETS indicator/warning light ashes and
LOW TRACTION appears on the Driver Information
Center (DIC) when the traction control system is actively
limiting wheel spin. The system may be heard or felt while
it is working, but this is normal. Slippery road conditions
may exist if this message is displayed, so adjust your
driving accordingly.
If the vehicle is in cruise control when the ETS begins
to limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. SeeCruise Control on page 3-10.The ETS indicator/warning light may come on for the
following reasons:
The indicator/warning light ashes while the traction
control system is limiting wheel spin.
If the system is turned off by moving the shift lever
to L (Low), the indicator/warning light comes on
and stays on. To turn the system back on, move
the shift lever back to a position other than L (Low).
The indicator/warning light should go off.
The indicator/warning light will come on when the
parking brake is set with the engine running, and it
will stay on if the parking brake does not release fully.
If the transmission shift lever is in any position other
than L (Low) and the indicator/warning light stays on
after the parking brake is fully released, there is a
problem with the system.
If the traction control system is affected by an engine
related problem, the system will turn off and the
indicator/warning light will come on.
4-12

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 L (Low), the
vehicle may need service.
When this light is on solid, the system will not limit
wheel spin. Adjust your driving accordingly.
Check the 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 the vehicle
requires service. When this light is turned on, either the
SERVICE TRACTION or TRACTION OFF message
will be displayed.
SeeDIC Warnings and Messages on page 3-50for
more information on the messages associated with
this light.
To limit wheel spin, especially in slippery road
conditions, ETS should always be left on. But the
system can be turned off if needed.
To turn the system off, shift to L (Low) or R (Reverse).
When the system is turned off, the ETS indicator/warning
light will come on and stay on and the TRACTION OFF
message will be displayed when the gear shift is in
L (Low). The indicator/warning light and message will
not come on when the gear shift is in R (Reverse).If the ETS is limiting wheel spin when the transmission is
shifted to L (Low) or R (Reverse) to turn the system off,
the indicator/warning light and TRACTION OFF will come
on in L (Low). But the system will not turn off right away.
It will wait until there is no longer a current need to limit
wheel spin. SeeDIC Warnings and Messages on
page 3-50for more information on the messages
associated with this light.
The system can be turned back on at any time by
shifting to D (Automatic Overdive) or I (Intermediate).
The ETS indicator/warning light should go off.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
Limited-Slip Differential
Vehicles with a limited-slip differential can give more
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when traction
is low, this feature allows the drive wheel with the most
traction to move the vehicle. The limited slip design
has minimal impact to the steering feel, but boosts the
traction performance under all conditions.
4-13

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 the 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 N (Neutral) 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 the vehicle in gear when going 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.
4-21

Rocking Your Vehicle to Get It Out
Turn the steering wheel left and right to clear the area
around the front wheels. Turn off any traction system.
Shift back and forth between R (Reverse) and a forward
gear, or with a manual transmission, between 1 (First) or
2 (Second) and R (Reverse), 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 shifting, and press lightly on the
accelerator pedal when the transmission is in gear.
Slowly spinning the wheels in the forward and reverse
directions causes a rocking motion that could free the
vehicle. If that does not get the vehicle out after a few
tries, it might need to be towed out. If the vehicle does
need to be towed out, seeTowing Your Vehicle on
page 4-31.
Loading the Vehicle
It is very important to know how much weight your
vehicle can carry. Two labels on your vehicle show
how much weight it may properly carry, the Tire
and Loading Information label and the Vehicle
Certication label.
{CAUTION:
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or
either the maximum front or rear Gross Axle
Weight Rating (GAWR). If you do, parts on the
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of the vehicle.
4-25

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’s 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 for your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer (Automatic Transmission) on page 4-34or
Towing a Trailer (Manual Transmission) on
page 4-41for important information on towing a
trailer, towing safety rules, and trailering tips.
4-27

Here are some important things to consider before
recreational vehicle towing:
What is the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer’s
recommendations.
What is the distance that will be travelled? Some
vehicles have restrictions on how far and how
long they can tow.
Is the proper towing equipment going to be used?
See your dealer/retailer or trailering professional
for additional advice and equipment
recommendations.
Is the vehicle ready to be towed? Just as preparing
the vehicle for a long trip, make sure the vehicle is
prepared to be towed. SeeBefore Leaving on a
Long Trip on page 4-20.
Dinghy Towing
Use the following procedure to dinghy tow the vehicle
from the front with all four wheels on the ground:
1. Set the parking brake.
2. Turn the ignition key to ACC/ACCESSORY to
unlock the steering wheel.
3. Shift the transmission to N (Neutral).
4. Release the parking brake.
4-32

Towing a Trailer
(Automatic Transmission)
{CAUTION:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is too
heavy, the brakes may not work well — or even at
all. The driver and passengers could be seriously
injured. The vehicle may also be damaged; the
resulting repairs would not be covered by the
vehicle warranty. Pull a trailer only if all the steps in
this section have been followed. Ask your dealer/
retailer for advice and information about towing a
trailer with the vehicle.
The vehicle can tow a trailer if it is equipped with an
automatic transmission and the proper trailer towing
equipment. If the vehicle is not equipped as stated
above, do not tow a trailer. To identify the trailering
capacity of the vehicle, read the information in “Weight
of the Trailer” that appears later in this section.Trailering is different than just driving the vehicle by itself.
Trailering means changes in handling, acceleration,
braking, cooling, durability and fuel economy. Successful,
safe trailering takes correct equipment, and it has to be
used properly.
The following information has 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 pulling 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.
SS Package
If the vehicle has the SS package, it is neither designed
nor intended to tow a trailer.
4-34

Pulling A Trailer
Here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
the 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.
Do not tow a trailer at all during the rst 500 miles
(800 km) the new vehicle is driven. The engine,
transmission or other parts could be damaged.
Then, during the rst 500 miles (800 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the 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 the 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 the vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (450 kg).
But even that can be too heavy.
It depends on how the rig is used. For example, speed,
altitude, road grades, outside temperature and how
much the vehicle is used to pull a trailer are all important.
It can depend on any special equipment on the vehicle,
and the amount of tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue” later in this section for
more information.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
Ask your dealer/retailer for our trailering information or
advice, or write us at our Customer Assistance Offices.
SeeCustomer Assistance Offices on page 7-6for more
information.
4-35

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 the vehicle. Frequent stops are
very important to allow the engine and transmission
to cool.
When towing under severe conditions such as hot
ambient temperatures or steep grades, the 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 3-50DIC Warnings and Messages
for more information.
Reduce speed and shift to a lower gearbeforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used 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 5-32.
Parking on Hills
{CAUTION:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on a
at surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
brake pedal until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking
brake and shift into P (Park).
5. Release the brake pedal.
