For vehicles with the 2.2L (VIN Code V) or 2.4L
(VIN Code B) engines, you can also reset the system
as follows:1. Turn the ignition key to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal slowly three times within five seconds.
3. Turn the key to LOCK/OFF, then start the engine.
If the CHANGE ENGINE OIL SOON message comes
back on when the vehicle is started, the engine oil life
system has not been reset. Repeat the procedure.
Engine Air Cleaner/Filter
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the scheduled
maintenance intervals and replace it at the first oil
change after each 80 000 km (50,000 mi) 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. Replace
filter if appears dusty or dirty.
How to Inspect the Engine Air Cleaner/
Filter
See Engine Compartment Overviewon page 6‑14for
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.
Because this operation can be a little difficult, you may
choose to have this done at the dealer service
department.

Manual Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to a
dealer for service. Have it repaired as soon as possible.
You may also have the fluid level checked by your
dealer when the oil is changed. SeeRecommended
Fluids and Lubricants
on page 7‑8for the proper fluid
to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives fluid from the brake master cylinder
reservoir.
See Brakes
on page 6‑30for more information.
Cooling System
The cooling system allows the engine to maintain the
correct working temperature.

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 5 years or 240 000 km
(150,000 mi), 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 6‑28
What to Use
{WARNING:
Adding only plain water or some other liquid to the
cooling system can be dangerous. Plain water
and other liquids, 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 7‑8for more information.
Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
6-24

Black plate (25,1)Chevrolet HHR Owner Manual - 2011
The coolant recovery tank
cap has this symbol on it.
The tank is located in the
engine compartment
toward the front of the
engine on the
passenger's side of the
vehicle.
See Engine Compartment Overview
on page 6‑14for
more information on location.
Check to see if coolant is visible in the coolant recovery
tank. If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down. If coolant is visible but the coolant level is not at or
above the COLD FILL mark, add a 50/50 mixture of
clean, drinkable water and DEX-COOL coolant at the
coolant recovery tank, but be sure the cooling system is
cool before this is done.
When the engine is cold, the coolant level should be at
the COLD FILL (A) line or a little higher. The COLD
FILL line is near the bottom of the tank and sticks out
from the rear of the tank.
When the engine is cold, the coolant level should be at
or above the COLD FILL line. If it is not, you may have
a leak in the cooling system.
6-25

Black plate (31,1)Chevrolet HHR Owner Manual - 2011
Do not top off the brake/clutch fluid. Adding fluid does
not correct a leak. If fluid is added when the brake
linings are worn, there will be too much fluid when new
brake linings are installed. Add or remove fluid, as
necessary, only when work is done on the brake/clutch
hydraulic system.
{WARNING:
If too much brake fluid is added, it can spill on the
engine and burn, if the engine is hot enough. You
or others could be burned, and the vehicle could
be damaged. Add brake fluid only when work is
done on the brake and/or clutch hydraulic system.
When the brake fluid falls to a low level, the brake
warning light comes on. See Brake System Warning
Light on page 4‑29.
What to Add
Use only new DOT 3 brake fluid from a sealed
container. See Recommended Fluids and Lubricantson
page 7‑8.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This helps keep dirt
from entering the reservoir.
{WARNING:
With the wrong kind of fluid in the brake or clutch
hydraulic system, the brakes or clutch might not
work well. This could cause a crash. Always use
the proper brake fluid.
Notice:
.Using the wrong fluid can badly damage
brake or clutch hydraulic system parts. For
example, just a few drops of mineral-based
oil, such as engine oil, in the brake or clutch
hydraulic system can damage brake or
clutch hydraulic system parts so badly that
they will have to be replaced. Do not let
someone put in the wrong kind of fluid.
.If brake fluid is spilled on the vehicle's
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on the vehicle. If you do, wash it off
immediately. See Washing Your Vehicle
on
page 6‑95

Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed. Tires should be rotated every
12 000 km/7,500 miles. SeeTire Inspection and
Rotation on page 6‑60.
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. See Engine Oilon
page 6‑16. An Emission Control Service.
When the CHANGE OIL SOON message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset. Your
dealer has trained service technicians who will perform
this work and reset the system. If the engine oil life
system is reset accidentally, service the vehicle within
5 000 km/3,000 miles since the last service. Reset the
oil life system whenever the oil is changed. See Engine
Oil Life System on page 6‑19.
When the Change Oil Soon message displays, certain
services, checks, and inspections are required.
Every Engine Oil Change
.Change engine oil and filter. Reset oil life system.
See Engine Oilon page 6‑16andEngine Oil Life
