warning CHEVROLET HHR 2010 1.G Owners Manual

When replacing the fuel cap, turn it clockwise until
it clicks. Make sure the cap is fully installed. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. This would allow
fuel to evaporate into the atmosphere. SeeMalfunction
Indicator Lamp on page 4‑35.
The CHECK GAS CAP message displays on the Driver
Information Center (DIC) if the fuel cap is not properly
installed. See DIC Warnings and Messages
on
page 4‑48for more information.
To close the fuel door securely, push the door to the
closed position.
{WARNING:
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow of fuel by
shutting off the pump or by notifying the station
attendant. Leave the area immediately.
Notice: If you need a new fuel cap, be sure to get
the right type. Your dealer/retailer can get one
for you. If you get the wrong type, it may not fit
properly. This may cause the malfunction indicator
lamp to light and may damage the fuel tank and
emissions system. See Malfunction Indicator Lamp
on page 4‑35.

Filling a Portable Fuel Container
{WARNING:
Never fill a portable fuel container while it is in
the vehicle. Static electricity discharge from the
container can ignite the fuel vapor. You can be
badly burned and the vehicle damaged if this
occurs. To help avoid injury to you and others:
.Dispense fuel only into approved containers.
.Do not fill a container while it is inside a
vehicle, in a vehicle's trunk, pickup bed, oron any surface other than the ground.
(Continued)
WARNING: (Continued)
.Bring the fill nozzle in contact with the inside
of the fill opening before operating the nozzle.
Contact should be maintained until the filling is
complete.
.Do not smoke while pumping fuel.
.Do not use a cellular phone while
pumping fuel.

Checking Things Under
the Hood
{WARNING:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing, and tools away from any
underhood electric fan.
{WARNING:
Things that burn can get on hot engine parts and
start a fire. These include liquids like fuel, oil,
coolant, brake fluid, windshield washer and other
fluids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things
that will burn onto a hot engine.

Cold Temperature Operation
For Vehicles With the 2.2L or
2.4L L4 Engine
If in an area of extreme cold, where the temperature
falls below−20°F (−29°C), use either an SAE 5W-30
synthetic oil or an SAE 0W-30 engine oil. Both provide
easier cold starting for the engine at extremely low
temperatures. Always use an oil that meets the required
specification, GM6094M. See “What Kind of Engine Oil
to Use” for more information.
Engine Oil Additives / Engine Oil
Flushes
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM standards are
all that is needed for good performance and engine
protection.
Engine oil system flushes are not recommended and
could cause engine damage not covered by the vehicle
warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has the Engine Oil Life System, a computer
system that indicates when to change the engine oil
and filter. This is based on engine revolutions and
engine temperature, and not on mileage. Based on
driving conditions, the mileage at which an oil change is
indicated can vary considerably. For the oil life system
to work properly, the system must be reset every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it indicates that an oil change is necessary.
A CHANGE OIL SOON message comes on. See DIC
Warnings and Messages
on page 4‑48. Change the
oil as soon as possible within the next 600 miles
(1 000 km). It is possible that, if driving under the best
conditions, the oil life system might not indicate that an
oil change is necessary for over a year. However, the
engine oil and filter must be changed at least once a
year and at this time the system must be reset. Your
dealer/retailer has trained service people who will
perform this work using genuine parts and reset the
system. It is also important to check the oil regularly
and keep it at the proper level.
6-23

What to Do with Used Oil
Used engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good hand
cleaner. Wash or properly dispose of clothing or rags
containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it in
the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Recycle it by taking it to a
place that collects used oil.
Engine Air Cleaner/Filter
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the MaintenanceII
intervals and replace it at the first oil change after each
50,000 mile (80 000 km) interval. See Scheduled
Maintenance
on page 7‑3for more information. If you
are driving in dusty/dirty conditions, inspect the filter at
each engine oil change. The 2.0L engine inspect at
each oil change. Replace filter if appears dusty or dirty.
How to Inspect the Engine Air
Cleaner/Filter (2.2L and 2.4L Engines)
See Engine Compartment Overviewon page 6‑16for
the location of the engine air cleaner/filter.
To inspect the air cleaner/filter remove the filter from the
vehicle and lightly shake the filter to release loose dust
and dirt. If the filter remains caked with dirt, a new filter
is required. Never use compressed air to clean the filter.
6-25

To inspect or replace the filter, do the following:1. Remove the screws that hold the housing and cover together and lift off the cover.
2. Inspect or replace the engine air cleaner/filter.
3. Reverse the steps to reinstall the system. Be sure to reinstall the housing tightly.
{WARNING:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. Use caution when
working on the engine and do not drive with the
air cleaner/filter off.
Notice: If the air cleaner/filter is off, dirt can easily
get into the engine, which could damage it. Always
have the air cleaner/filter in place when you are
driving.
Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take your vehicle to a dealer/
retailer and have it repaired as soon as possible.
Change the fluid and filter at the intervals listed in the
Maintenance Schedule. See Scheduled Maintenance
on page 7‑3. Be sure to use the transmission fluid
listed in Recommended Fluids and Lubricantson
page 7‑10.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7‑10.

{WARNING:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{WARNING:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them. If you
do, you can be burned.
Do not run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.Notice:
Using coolant other than DEX-COOL
®can
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 50 000 km (30,000 miles)
or 24 months, whichever occurs first. Any repairs
would not be covered by the vehicle warranty.
Always use DEX-COOL
®(silicate-free) coolant in
the vehicle.
Engine Coolant
The cooling system in the vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first.
The following explains the cooling system and how
to check and add coolant when it is low. If there is a
problem with engine overheating, see Engine
Overheating on page 6‑34
6-29

What to Use
{WARNING:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper
coolant mixture will. The vehicle's coolant warning
system is set for the proper coolant mixture. With
plain water or the wrong mixture, the engine could
get too hot but you would not get the overheat
warning. The engine could catch fire and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing else
needs to be added. This mixture:
.Gives freezing protection down to −34°F (−37°C),
outside temperature.
.Gives boiling protection up to 265°F (129°C),
engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine temperature.
Notice: If an improper coolant mixture is used, the
engine could overheat and be badly damaged. The
repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice: If extra inhibitors and/or additives are used
in the vehicle's cooling system, the vehicle could be
damaged. Use only the proper mixture of the engine
coolant listed in this manual for the cooling system.
See Recommended Fluids and Lubricants
on
page 7‑10for more information.

How to Add Coolant to the Cooling
System
{WARNING:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot enough.
Do not spill coolant on a hot engine.
Notice: This vehicle has a specific coolant fill
procedure. Failure to follow this procedure could
cause the engine to overheat and be severely
damaged.
{WARNING:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{WARNING:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the surge tank
pressure cap —even a little —they can come out
at high speed. Never turn the cap when the
cooling system, including the surge tank pressure
cap, is hot. Wait for the cooling system and surge
tank pressure cap to cool if you ever have to turn
the pressure cap.
6-32

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.
