2012 GMC CANYON wheel torque

Black plate (14,1)GMC Canyon Owner Manual - 2012
1-14 In Brief
Four-Wheel Drive
Four-wheel drive sends engine
power to all four wheels for extra
traction.
The transfer case buttons are
located to the right of the steering
wheel on the instrument panel.Use these buttons to shift into and
out of four-wheel drive.
2
m(Two-Wheel High):
Use for
driving in most street and highway
situations.
{WARNING
Shifting the transfer case to
N (Neutral) can cause the vehicle
to roll even if the transmission is
in P (Park). You or someone else
could be seriously injured. Be
sure to set the parking brake
before placing the transfer case in
N (Neutral). See Parking Brake on
page 9‑42. N (Neutral):
Use the N (Neutral)
position only when towing the
vehicle. See Recreational Vehicle
Towing on page 10‑91.
4
m(Four-Wheel High): Use when
extra traction is needed in most
off-road situations.
4
n(Four-Wheel Low): Use this
position to deliver extra torque to all
four wheels. Used for extreme off‐
road conditions. See Four-Wheel
Drive on page 9‑37.

Driving and Operating 9-29
{WARNING
If you have four-wheel drive, the
vehicle will be free to roll—even
if the shift lever is in P (Park) —if
the transfer case is in Neutral. So,
be sure the transfer case is in a
drive gear, two-wheel high (2H) or
four-wheel high (4H) or
four-wheel low (4L) —not
in Neutral.
2. Move the shift lever into P (Park) by pulling the lever toward you
and moving it up as far as it
will go.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can leave the vehicle
with the key, the vehicle is in
P (Park).
Leaving the Vehicle With the
Engine Running (Automatic
Transmission)
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set. And, if you leave the
vehicle with the engine running, it
could overheat and even catch
fire. You or others could be
injured. Do not leave the vehicle
with the engine running.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold the
regular brake pedal down. Then,
see if you can move the shift lever away from P (Park) without first
pulling it toward you. If you can, the
shift lever was not fully locked into
P (Park).
Torque Lock
(Automatic Transmission)
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of the
vehicle may put too much force on
the parking pawl in the
transmission. You may find it difficult
to pull the shift lever out of P (Park).
This is called torque lock. To
prevent torque lock, set the parking
brake and then shift into P (Park)
properly before you leave the driver
seat. To find out how, see
“Shifting
Into Park (Automatic Transmission)”
in this section.
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake.
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of

Vehicle Care 10-27
Brakes
This vehicle has front disc brakes
and rear drum 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.
Rear drum brakes 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. Drum brakes
have an inspection hole to inspect
lining wear during scheduled
maintenance. 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 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.

Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on
page 10‑58.
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 time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle.
(Continued)
WARNING (Continued)
In an emergency, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later 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.
Some commercial truck tires
may not have treadwear indicators.

{WARNING
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 specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications on page 12‑2 for
original equipment wheel nut
torque specifications.
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. See
Capacities and Specifications on
page 12‑2 for the wheel nut
torque specification.
12. Tighten the wheel nuts firmly in a crisscross sequence, as
shown, by turning the wheel
wrench clockwise.
Reinstall the center cap when
the regular wheel and tire are
reinstalled. Place the cap on the
wheel and tap it into place until it is
flush with the wheel. The cap only
goes on one way. Be sure to line up
the tab on the center cap with the
indentation on the wheel.
Storing a Flat or Spare Tire
and Tools
{WARNING
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.
Notice: Storing an aluminum
wheel with a flat tire under your
vehicle for an extended period of
time or with the valve stem
pointing up can damage the
wheel. Always stow the wheel
with the valve stem pointing
down and have the wheel/tire
repaired as soon as possible.
Store the tire under the rear of the
vehicle in the spare tire carrier.
1. Put the tire on the ground at the rear of the vehicle with the valve
stem pointed down.
