wheel hub GMC ENVOY 2006 Owner's Manual

{CAUTION:
If something is between an occupant and an
airbag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the
steering wheel hub or on or near any other
airbag covering. And, if your vehicle has
roof-mounted side impact airbags, never
secure anything to the roof of your vehicle by
routing the rope or tiedown through any door
or window opening. If you do, the path of an
inating side impact airbag will be blocked.
The path of an inating airbag must be
kept clear.
When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal or
near-frontal crashes. But they are designed to inate only
if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a crash is
likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags will
or should deploy is not based on how fast your vehicle is
traveling. It depends largely on what you hit, the direction
of the impact and how quickly your vehicle slows down.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with electronic frontal sensors,
which help the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. For moderate frontal impacts, these airbags
inate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs. If
the front of your vehicle goes straight into a wall
that does not move or deform, the threshold level for
the reduced deployment is about 9 to 16 mph (14
to 26 km/h), and the threshold level for a full deployment
is about 18 to 25 mph (29 to 40 km/h). (The threshold
level can vary, however, with specic vehicle design, so
that it can be somewhat above or below this range.)

What Will You See After an Airbag
Inates?
After a frontal airbag inates, it quickly deates, so
quickly that some people may not even realize
the airbag inated. Roof-mounted side impact airbags
deate more slowly and may still be at least partially
inated minutes after the vehicle comes to rest. Some
components of the airbag module may be hot for a short
time. These components include the steering wheel
hub for the driver’s frontal airbag and the instrument
panel for the right front passenger’s frontal airbag. For
vehicles with side impact airbags, the ceiling of your
vehicle near the side windows may be hot. The parts of
the bag that come into contact with you may be
warm, but not too hot to touch. There will be some
smoke and dust coming from the vents in the deated
airbags. Airbag ination does not prevent the driver from
seeing out of the windshield or being able to steer the
vehicle, nor does it stop people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment, you
should seek medical attention.
Your vehicle has a feature that may automatically
unlock the doors and turn the interior lamps on when
the airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.

Driving in Mud, Sand, Snow, or Ice
When you drive in mud, snow, or sand, the wheels will
not get good traction. You cannot accelerate as
quickly, turning is more difficult, and you will need longer
braking distances.
It is best to use a low gear when you are in mud — the
deeper the mud, the lower the gear. In really deep
mud, the idea is to keep your vehicle moving so you do
not get stuck.
When you drive on sand, you will sense a change in
wheel traction. But it will depend upon how loosely
packed the sand is. On loosely packed sand, such as
on beaches or sand dunes, the tires will tend to sink into
the sand. This has an effect on steering, accelerating,
and braking. Drive at a reduced speed and avoid sharp
turns or abrupt maneuvers.
Hard packed snow and ice offer the worst tire traction.
On these surfaces, it is very easy to lose control.
On wet ice, for example, the traction is so poor that you
will have difficulty accelerating. And if you do get
moving, poor steering and difficult braking can cause
you to slide out of control.{CAUTION:
Driving on frozen lakes, ponds, or rivers can
be dangerous. Underwater springs, currents
under the ice, or sudden thaws can weaken the
ice. Your vehicle could fall through the ice and
you and your passengers could drown. Drive
your vehicle on safe surfaces only.
Driving in Water
Heavy rain can mean ash ooding, and ood waters
demand extreme caution.
Find out how deep the water is before you drive through
it. If it is deep enough to cover the wheel hubs, axles
or exhaust pipe, do not try it — you probably will not get
through. Also, water that deep can damage the axle
and other vehicle parts.

5. Tilt the retainer at the end of the cable when the
tire has been completely lowered, and pull it
through the wheel opening.
6. Pull the tire out from under the vehicle.
Notice:If you drive away before the spare tire or
secondary latch system cable has been reinstalled,
you could damage your vehicle. Always reinstall
this cable before driving your vehicle.
7. Put the spare tire near the at tire.
Removing the Flat Tire and
Installing the Spare Tire
1. If your vehicle has a hubcap that covers the wheel
nuts, position the chisel end of the wheel wrench in
the notch and pry it off.
5-78

{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.
10. Put the nuts on by hand. Make sure the rounded
end is toward the wheel.
11. Tighten each nut by hand until the wheel is held
against the hub. If a nut cannot be turned by
hand, use the wheel wrench and see your dealer
as soon as possible.
12. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.

Follow this diagram to store the underbody-mounted
spare tire.
A. Wheel Wrench
B. Hoist Shaft
C. Extension(s)
D. Retainer
E. Spare or Flat Tire
(Valve Stem
Pointed Up)
1. Put the tire (E) on the ground at the rear of the
vehicle.
2. Remove the hubcap, if equipped, from the at tire
by tapping the backside of the hubcap with the
wheel wrench (A). Store in a safe location until the
at tire is repaired. Once the tire is repaired,
replace the hubcap.
3. Ensure the valve stem is pointed up and to the rear.
4. Pull the retainer (D) through the wheel.
5. Put the socket end of the extension (C), on a
45 degree angle downward, through the hole just
above the rear bumper and connected to the hoist
shaft (B).6. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench (A)
clockwise until you hear two clicks or feel it
skip twice. This indicates that the tire is secure and
the cable is tight. The spare tire hoist cannot be
overtightened.
7. Make sure the tire is stored securely. Push, pull (A),
and then try to turn (B) the tire. If the tire moves,
use the wheel wrench and socket end of the
extension to tighten the cable.
