2009 CHEVROLET HHR wheel torque

Region A Gage and Speedometer
Displays
Change the information displayed in Region A by
turning the knob either clockwise or counterclockwise.
The available gages are:
BOOST:Displays positive boost pressure as
determined by the manifold air pressure (MAP) sensor.
AIR/FUEL RATIO:Displays the mass ratio of air
to fuel.
CAM PHASER ANGLES:Displays orientation of the
intake and exhaust cam shafts relative to their park
positions as commanded by the engine control module.
OVERLAP represents the total distance the intake and
exhaust cam shafts have phased.
SPARK ADVANCE/ KNOCK RETARD:The spark
advance gage displays ignition timing. Knock retard
indicates the amount of ignition delay to reduce spark
knock.
ENGINE POWER & TORQUE:Displayed engine power
and torque are engine ywheel output values calculated
by the engine control module. These values are
approximate and may change with the air conditioning
load, generator output, air temperature, air pressure, and
fuel octane.SPEEDOMETER&GFORCE:The G FORCE meter
displays lateral acceleration. While turning right, G forces
are felt on the left, and vice versa. PEAK values are
stored indenitely, and can be reset with a press and hold
of the RPD knob while viewing the G FORCE meter.
SETUP MENU:Press the RPD knob to enter this menu.
The vehicle should be stopped while conguring the
setup menu selections.
SCREEN OFF:Turns the screen off.
Region B Readout Displays
Press the RPD knob to highlight Region B. The
information displayed can be changed by turning
the RPD knob either clockwise or counterclockwise.
Press the RPD knob again, to store the selection.
The selection will also be stored after a few seconds
of no activity. Available modes are:
Readouts #1
SHIFT LIGHTS/GEAR INDICATION:The shift lights
provide visual identication of engine speed for a
transmission gear. Shift light minimum and maximum
RPM settings can be viewed and congured in the
SETUP screen.

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 rmly.
{CAUTION:
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 rst 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 specications in
Capacities and Specifications on page 5-114.
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.
5-37

Any time you notice unusual wear, rotate the tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 5-69
andWheel Replacement on page 5-73.
When rotating the vehicle’s tires, always use the
correct rotation pattern shown here.
Do not include the compact spare tire in the tire
rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the Tire
and Loading Information label. SeeInflation - Tire
Pressure on page 5-61andLoading the Vehicle on
page 4-25.Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 5-64.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-114.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the
vehicle. In an emergency, you can use a
cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if needed, to get all the rust or dirt off.
SeeChanging a Flat Tire on page 5-76.

{CAUTION:
Wheel nuts that are improperly or incorrectly
tightened can cause the wheels to become loose or
come off. The wheel nuts should be tightened with
a torque wrench to the proper torque specication
after replacing. Follow the torque specication
supplied by the aftermarket manufacturer when
using accessory locking wheel nuts. SeeCapacities
and Specifications on page 5-114for original
equipment wheel nut torque specications.Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque
specication. SeeCapacities and Specifications on
page 5-114for the wheel nut torque specication.
10. Tighten the wheel nuts
rmly in a crisscross
sequence as shown.

Storing a Flat or Spare Tire and
Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these in
the proper place.
