2007 HUMMER H3 tow

This light should come on, as a check to show
you it is working, when the ignition is on and
the engine is not running. If the light does
not come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system
on your vehicle. Diagnosis and service may
be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.If the light continues to ash, when it is safe to
do so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service
as soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 318.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose
or missing fuel cap will allow fuel to evaporate into
the atmosphere. A few driving trips with the cap
properly installed should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The
condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.

By slowly spinning the wheels in the forward
and reverse directions, you will cause a rocking
motion that may free your vehicle. If that does
not get your vehicle out after a few tries, it
may need to be towed out. Or, you can use the
recovery loops. If your vehicle does need to
be towed out, seeTowing Your Vehicle
on page 294.
Recovery Loops
{CAUTION:
These loops, when used, are under a lot
of force. Keep people away from the
vicinity of the loops and any chains or
cables during use. Always pull the vehicle
straight out. Never pull on the loops at a
sideways angle. The loops could break off
and you or others could be injured from
the chain or cable snapping back.Notice:Never use the recovery loops to tow
the vehicle. Your vehicle could be damaged
and it would not be covered by warranty.
Your vehicle has
two recovery loops
at the front of the
vehicle and one at the
rear of the vehicle.
You may need to use them if you are stuck
off-road and need to be pulled to some place
where you can continue driving.Rear of Vehicle

If your vehicle has a brush guard, never tow or
apply any loads onto the brush guard.Front of Vehicle

The Tire and Loading Information label also shows
the size of your vehicle’s original equipment tires
(C) and the recommended cold tire ination
pressures (D). For more information on tires and
ination seeTires on page 367andInation - Tire
Pressure on page 375.
There is also important information on the
Certication/Tire label. It tells you the Gross
Vehicle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for the front and
rear axles. See “Certication/Tire Label” later in
this section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle’s placard.
2. Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.4. The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 650 lbs (1400−750 (5 x 150) = 650 lbs).
5. Determine the combined weight of luggage
and cargo being loaded on the vehicle.
That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity of your vehicle.
SeeTowing a Trailer on page 297for important
information on towing a trailer, towing safety,
and trailering tips.

If you put things inside your vehicle — like
suitcases, tools, packages, or anything
else — they will go as fast as the vehicle goes.
If you have to stop or turn quickly, or if there
is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops
of the seats.
Do not leave an unsecured child
restraint in your vehicle.
CAUTION: (Continued)
CAUTION: (Continued)

When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.
There is also important loading information for

Vehicle for Off-Road Driving”underOff-Road
Driving on page 250.
