Wheel Nut Torque CHEVROLET VOLT 2011 Owner's Manual

Brakes
This vehicle has 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
a crash. 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 12‑2.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer 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.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front
and rear brakes —for the worse.
The braking performance expected
can change in many other ways if
the wrong replacement brake parts
are installed.

10-62 Vehicle Care
Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque” underCapacities
and Specifications on
page 12‑2.
{WARNING
Rust or dirt on a wheel,
or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. When
changing a wheel, remove
any rust or dirt from places
where the wheel attaches to
the vehicle. In an emergency,
a cloth or a paper towel can
be used, however, use a
scraper or wire brush to
remove all rust or dirt. Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change
or tire rotation to prevent
corrosion or rust build-up.
Do not get grease on the flat
wheel mounting surface or
on the wheel nuts or bolts.
When It Is Time for New
Tires
Factors, such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.Treadwear indicators are one way
to tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. See
Tire
Inspection on page 10‑61 and
Tire Rotation on page 10‑61
for additional information.

10-68 Vehicle Care
Replace wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor
System (TPMS) sensors with new
GM original equipment parts.
{WARNING
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling
of the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Notice: The wrong wheel
can also cause problems with
bearing life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle ground
clearance, and tire clearance
to the body and chassis.
{WARNING
Rust or dirt on a wheel,
or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. When
changing a wheel, remove
any rust or dirt from places
where the wheel attaches to
the vehicle. In an emergency,
a cloth or a paper towel can
be used, however, use a
scraper or wire brush to
remove all rust or dirt.
{WARNING
Never use oil or grease on studs
or the threads of the wheel nuts.
The wheel nuts might come loose
and the wheel could fall off,
causing a crash.
{WARNING
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead
to a crash. Be sure to use the
correct wheel nuts. If you have
to replace them, be sure to get
new GM original equipment
wheel nuts.
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 specification.
