warning CHEVROLET HHR 2010 1.G Owners Manual

Launch Control (SS Models Only)
Launch Control is a form of traction control, to control
tire spin while launching the vehicle during closed track
events and competitive driving. The feature is activated
when the vehicle is at rest while in Competitive Mode.
At rest, if the accelerator pedal is pressed to the floor
with the clutch engaged, the RPM is limited to a
predetermined level. A smooth, quick release of the
clutch while keeping the accelerator pedal on the floor
will provide controlled wheel spin for consistent
acceleration. Complete shifts as described inManual
Transmission Operation on page 3‑31.
LAUNCH CONTROL displays in the DIC after the
COMPETITIVE MODE message, when the vehicle is
stopped. The system will exit to COMPETITIVE MODE
after the vehicle is launched. See “Competitive Driving
Mode” earlier in this section. The normal Traction
Control System (TCS) will not be operating while in the
Competitive Driving mode and the TCS light on the
instrument panel cluster comes on. Adjust your driving
accordingly. See DIC Warnings and Messages
on
page 4‑48for more information.
Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the front wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power by closing the throttle and managing engine
spark to limit wheel spin.
This light flashes while
the traction control system
is limiting wheel spin.
The system may be heard or felt while it is working.
This is normal and does not mean there is a problem
with the vehicle.
See Electronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light
on page 4‑33for
more information.
5-9

If the vehicle is in cruise control while TCS begins to
limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. SeeTurn Signal/Multifunction
Lever on page 4‑4.
When this light is on and
either the SERVICE
TRACTION or TRACTION
OFF message is
displayed, the system
will not limit wheel spin.
Adjust your driving accordingly. See DIC Warnings and
Messages
on page 4‑48for more information.
The Traction Control System comes on automatically
whenever the vehicle is started. It is recommended to
leave the system on for normal driving conditions, but
it may be necessary to turn the system off if the vehicle
is stuck in sand, mud, ice or snow, and you want to
“rock” your vehicle to attempt to free it. It may also be
necessary to turn off the system when driving in off-road
conditions where high wheel spin is required. See If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑23.
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 flash
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,
see Driver Information Center (DIC) on page 4‑46.
5-10

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, the
differential 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 flashes and the cruise
control automatically disengages. The cruise control
can be re-engaged when road conditions allow. See
Cruise Control on page 4‑8. Adding non‐dealer/non‐retailer accessories can affect
the vehicle's performance. See
Accessories and
Modifications
on page 6‑3for more information.
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 flashes 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. See Cruise Control on page 4‑8.
5-11

The ETS indicator/warning light may come on for the
following reasons:
.The indicator/warning light flashes 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.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.
See
DIC Warnings and Messages
on page 4‑48for
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
5-12

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 4‑48for 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. See Accessories and
Modifications
on page 6‑3for 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.
Steering
Electric Power Steering
If the engine stalls while driving, the power steering
assist system will continue to operate until you are
able to stop the vehicle. If power steering assist is lost
because the electric power steering system is not
functioning, the vehicle can be steered but it will take
more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time, you
may notice a reduced amount of power steering assist.
The normal amount of power steering assist should
return shortly after a few normal steering movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems and/or the POWER STEERING message
comes on, contact your dealer/retailer for service
repairs. See DIC Warnings and Messages
on
page 4‑48.
5-13

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking
reasonable care suited to existing conditions, and
by not overdriving those conditions. But skids are
always possible.
The three types of skids correspond to the vehicle's
three control systems. In the braking skid, the wheels
are not rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip
and lose cornering force. And in the acceleration skid,
too much throttle causes the driving wheels to spin.
If the vehicle has the Traction Control System (TCS) or
the Enhanced Traction System (ETS), remember: It
helps to avoid only the acceleration skid. SeeTraction
Control System (TCS)
on page 5‑9or Enhanced
Traction System (ETS)on page 5‑11. If the vehicle
does not have TCS or ETS, or if the system is off, then
an acceleration skid is best handled by easing your foot
off the accelerator pedal.
If the vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
the vehicle may straighten out. Always be ready for a
second skid if it occurs. If the vehicle has Electronic Stability Control (ESC), the
ESC might activate. See
Electronic Stability Control
(ESC) on page 5‑6.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, slow
down and adjust your driving to these conditions. It is
important to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including reducing vehicle speed by shifting
to a lower gear. Any sudden changes could cause the
tires to slide. You may not realize the surface is slippery
until the vehicle is skidding. Learn to recognize warning
clues —such as enough water, ice, or packed snow on
the road to make a mirrored surface —and slow down
when you have any doubt.
If the vehicle has the Antilock Brake System (ABS),
remember: It helps avoid only the braking skid. If the
vehicle does not have ABS, then in a braking skid,
where the wheels are no longer rolling, release enough
pressure on the brakes to get the wheels rolling again.
This restores steering control. Push the brake pedal
down steadily when you have to stop suddenly. As long
as the wheels are rolling, you will have steering control.
5-16

Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction and
affect your ability to stop and accelerate. Always drive
slower in these types of driving conditions and avoid
driving through large puddles and deep‐standing or
flowing water.
{WARNING:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of the
vehicle.
After driving through a large puddle of water or a
car/vehicle wash, lightly apply the brake pedal
until the brakes work normally.
Flowing or rushing water creates strong forces.
Driving through flowing water could cause your
vehicle to be carried away. If this happens, you
and other vehicle occupants could drown. Do not
ignore police warnings and be very cautious about
trying to drive through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle's tires so they actually ride on the water.
This can happen if the road is wet enough and you are
going fast enough. When your vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about hydroplaning. The
best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in good shape.
.Keep the windshield washer fluid reservoir filled.
.Have good tires with proper tread depth. SeeTireson page 6‑54.
.Turn off cruise control.
5-18

Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on flat or rolling terrain. Tips for driving in
these conditions include:
.Keep the vehicle serviced and in good shape.
.Check all fluid levels and brakes, tires, cooling
system, and transmission.
.Going down steep or long hills, shift to a
lower gear.
{WARNING:
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.
{WARNING:
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.
5-20

Blizzard Conditions
Being stuck in snow can be in a serious situation. Stay
with the vehicle unless there is help nearby. If possible,
use theRoadside Assistance Program
on page 8‑6.
To get help and keep everyone in the vehicle safe:
.Turn on the Hazard Warning Flasherson
page 4‑3.
.Tie a red cloth to an outside mirror.
{WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
.Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
.Check again from time to time to be sure
snow does not collect there.
(Continued)
WARNING: (Continued)
.Open a window about 5 cm (two inches) on
the side of the vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on or under the
instrument panel.
.Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting. See
Climate Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 3‑39.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.
Run the engine for short periods only as needed to
keep warm, but be careful.
5-22

To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine
off and close the window most of the way to save heat.
Repeat this until help arrives but only when you feel
really uncomfortable from the cold. Moving about to
keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator pedal
slightly so the engine runs faster than the idle speed.
This keeps the battery charged to restart the vehicle
and to signal for help with the headlamps. Do this as
little as possible to save fuel.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 5‑24.
If the vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to the vehicle's traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{WARNING:
If the 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 fire or other damage. Spin the
wheels as little as possible and avoid going above
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
see Tire Chains on page 6‑77.
