ECO GMC ENVOY DENALI 2007 Owners Manual

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has
been used or how far it has been driven. It
could fail suddenly and cause a crash. If
you have to replace a wheel, use a new
GM original equipment wheel.
Tire Chains
{CAUTION:
Do not use tire chains. There is not
enough clearance. Tire chains used on a
vehicle without the proper amount of
clearance can cause damage to the
brakes, suspension, or other vehicle
parts. The area damaged by the tire
chains could cause you to lose control of
your vehicle and you or others may be
injured in a crash. Use another type of
traction device only if its manufacturer
recommends it for use on your vehicle
and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to
your vehicle, drive slowly, re-adjust or
remove the device if it is contacting your
vehicle, and do not spin your wheels. If
you do nd traction devices that will t,
install them on the rear tires.

1. Attach the appropriate nozzle adapter
to the end of the hose, if required.
{CAUTION:
Inating something too much can make
it explode, and you or others could be
injured. Be sure to read the inator
instructions, and inate any object only
to its recommended pressure.
2. Attach that end of the hose to the object you
wish to inate.
3. Attach the other end of the hose to the outlet.

Secondary Latch System
Your vehicle has an underbody-mounted tire
hoist assembly equipped with a secondary latch
system. It is designed to stop the spare tire
from suddenly falling off your vehicle if the cable
holding the spare tire is damaged. For the
secondary latch to work, the tire must be stored
with the valve stem pointing up. SeeStoring
a Flat or Spare Tire and Tools on page 478
for instructions on storing the spare or at tire
correctly.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack.
If the spare tire does not slide off the jack
completely, make sure no one is behind
you or on either side of you as you pull
the jack out from the spare.
To release the spare tire from the secondary latch,
do the following:
1. Check under the
vehicle to see if
the cable is visible.
If it is not visible,
proceed to Step 6.
475

8. Continue raising the jack until the spare tire
stops moving upward and is held rmly in
place. The secondary latch has released and
the spare tire is balancing on the jack.
9. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack
until the spare tire slides off the jack or
is hanging by the cable.
10. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to
push against the spare while rmly pulling the
jack out from under the spare tire with the
other hand.
11. If the spare tire is
hanging from the
cable, insert
the socket end of
the extension
into the hoist shaft
hole on a 45 degree
angle downward.12. Be sure that the socket end of the extension
connects to the hoist shaft.
Turn the wheel wrench counterclockwise to
lower the spare the rest of the way.
477

13. Tilt the retainer at the end of the cable and pull
it through the wheel opening. 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.
14. Turn the wheel wrench clockwise to raise the
cable back up if the cable is hanging under
the vehicle.
Have the hoist assembly inspected as soon as
you can. You will not be able to store a spare
tire using the hoist assembly until it has been
repaired or replaced.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.
478

{CAUTION:
The underbody-mounted spare tire needs
to be stored with the valve stem pointing
up. If the spare tire is stored with the
valve stem pointing downward, its
secondary latch will not work properly
and the spare tire could loosen and
suddenly fall from your vehicle. If this
happened when your vehicle was being
driven, the tire might contact a person or
another vehicle, causing injury and, of
course, damage to itself as well. Be sure
the underbody-mounted spare tire is
stored with its valve stem pointing up.
Notice:An aluminum wheel with a at tire
should always be stored under the vehicle with
the hoist. However, storing it that way for an
extended period could damage the wheel.
To avoid this, always stow the wheel properly
with the valve stem pointing up and have
the wheel repaired as soon as possible.Follow this diagram to store the
underbody-mounted at or spare tire.
A. Wheel Wrench
B. Hoist Shaft
C. Extension
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 the vehicle has one,
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.

Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its
best if it is cleaned often. Although not always
visible, dust and dirt can accumulate on your
upholstery. Dirt can damage carpet, fabric, leather,
and plastic surfaces. Regular vacuuming is
recommended to remove particles from your
upholstery. It is important to keep your upholstery
from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes
of heat that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and
garments that transfer color to your home
furnishings may also transfer color to your
vehicle’s interior.
When leaning your vehicle’s interior, only use
cleaners specically designed for the surfaces
being cleaned. Permanent damage may result from
using cleaners on surfaces for which they were
not intended. Use glass cleaner only on glass.Remove any accidental over-spray from other
surfaces immediately. To prevent over-spray, apply
cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when
cleaning glass surfaces on your vehicle, you
could scratch the glass and/or cause damage
to the rear window defogger. When cleaning
the glass on your vehicle, use only a soft cloth
and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to all safety
instructions on the label. While cleaning your
vehicle’s interior, maintain adequate ventilation by
opening your vehicle’s doors and windows.
Dust may be removed from small buttons and
knobs using a small brush with soft bristles.
Your GM dealer has a product for cleaning your
vehicle’s glass. Should it become necessary,
you can also obtain a product from your GM dealer
to remove odors from your vehicle’s upholstery.
