2010 CHEVROLET HHR engine

The vehicle has an airbag system. Before attempting to
add anything electrical to the vehicle, seeServicing
Your Airbag-Equipped Vehicle
on page 2‑76and
Adding Equipment to Your Airbag-Equipped Vehicleon
page 2‑77.
Headlamp Wiring
The headlamp wiring is protected by fuses in the fuse
block. An electrical overload will cause the lamps to turn
off. If this happens, have the headlamp wiring checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it fixed.
Power Windows and Other Power
Options
Fuses in the fuse block protect the power windows.
When the current load is too heavy, the fuse opens
protecting the circuit until the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of damage caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and do not have
a spare fuse, you can “borrow”one that has the
same amperage. Just pick some feature of the vehicle
that you can get along without —like the radio or
cigarette lighter —and use its fuse if it is the
correct amperage. Replace it as soon as you can.
There are two fuse blocks in the vehicle: the floor
console fuse block and the engine compartment fuse
block.
There are also one or two fuses located at the back of
the vehicle near the battery.

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 when they have 8 000 to
13 000 km (5,000 to 8,000 miles). SeeTire Inspection
and Rotation on page 6‑69.
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. See Engine Oilon
page 6‑19. 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/retailer 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 6‑23.
When the Change Oil Soon message displays, certain
services, checks, and inspections are required. The
services described for Maintenance Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be
performed when:
.Maintenance Iwas performed the last time the
engine oil was changed.
.It has been 10 months or more since the Change
Oil Soon message has displayed or since the last
service.
