service indicator CHEVROLET HHR 2010 1.G Owner's Manual

Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance of
the emission control system could be affected. The
malfunction indicator lamp might turn on. If this occurs,
return to your dealer/retailer for service.
Fuel E85 (85% Ethanol)
The 8th digit of the Vehicle Identification Number (VIN)
shows the code letter or number that identifies the
vehicle's engine. The VIN is at the top left of the
instrument panel. SeeVehicle Identification Number
(VIN) on page 6‑118.
If your vehicle has the 2.2L L4 engine (VIN Code B) or
the 2.4L L4 engine (VIN Code V), you can use either
unleaded gasoline or ethanol fuel containing up to
85% ethanol (E85). See Fuel
on page 6‑5. In all
other engines, use only the unleaded gasoline
described under Gasoline Octane on page 6‑6. Only vehicles that have the 2.2L L4 engine
(VIN Code B) or the 2.4L L4 engine (VIN Code V)
can use 85% ethanol fuel (E85). We encourage the
use of E85 in vehicles that are designed to use it. The
ethanol in E85 is a
“renewable”fuel, meaning it is made
from renewable sources such as corn and other crops.
Many service stations will not have an 85% ethanol
fuel (E85) pump available. The U. S. Department
of Energy has an alternative fuels website
(www.eere.energy.gov/afdc/infrastructure/locator.html)
that can help you find E85 fuel. Those stations that
do have E85 should have a label indicating ethanol
content. Do not use the fuel if the ethanol content is
greater than 85%.
At a minimum, E85 should meet ASTM Specification
D 5798. By definition, this means that fuel labeled E85
will have an ethanol content between 70% and 85%.
Filling the fuel tank with fuel mixtures that do not meet
ASTM specifications can affect driveability and could
cause the malfunction indicator lamp to come on.

7. Start the engine and let it run until you can feel theupper radiator hose getting hot. Watch out for the
engine cooling fan.
8. By this time, the coolant level inside the radiator filler port may be lower. If the level is lower, add
more of the proper DEX-COOL
®coolant mixture
through the fill port until the level reaches the base
of the fill port.
9. Then replace the pressure cap. At any time during this procedure, if coolant begins to flow out of the
fill port, reinstall the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
10. When the engine has cooled, check the coolant in the coolant recovery tank. The level in the coolant
recovery tank should be at the COLD FILL line
when the engine is cold.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
You will find a coolant temperature warning light and a
coolant temperature gauge on your vehicle's instrument
panel. See Engine Coolant Temperature Warning Light
on page 4‑34andEngine Coolant Temperature Gaugeon page 4‑34for more information.
You may decide not to lift the hood when this warning
appears, but instead get service help right away. See
Roadside Assistance Program on page 8‑6.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fans are
running. If the engine is overheating, both fans should
be running. If they are not, do not continue to run the
engine and have the vehicle serviced.
Notice: Engine damage from running the engine
without coolant is not covered by the warranty.
Notice: If the engine catches fire because of being
driven with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered
by the vehicle warranty.

Brake Wear
This vehicle has front disc brakes and could have rear
drum brakes or rear disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound can come
and go or be heard all the time the vehicle is moving,
except when applying the brake pedal firmly.
{WARNING:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to
an accident. When the brake wear warning sound
is heard, have the vehicle serviced.
Notice: Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates can cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
the brakes. Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to torque specifications in
Capacities and Specifications on page 6‑125.
If the vehicle has rear drum brakes, they do not
have wear indicators, but if a rear brake rubbing
noise is heard, have the rear brake linings inspected
immediately. Rear brake drums should be removed and
inspected each time the tires are removed for rotation or
changing. When the front brake pads are replaced,
have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer/retailer if the brake pedal does not
return to normal height, or if there is a rapid increase in
pedal travel. This could be a sign that brake service
might be required.
Brake Adjustment
Every time the brakes are applied, with or without the
vehicle moving, the brakes adjust for wear.
