CHEVROLET HHR 2007 1.G Owners Manual

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 for your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer (Manual Transaxle) on page 276orTowing
a Trailer (Automatic Transaxle) on page 277for
important information on towing a trailer, towing
safety rules, and trailering tips.

272

Certication Label
A vehicle specic Certication/Tire label is found
on the rear edge of the driver’s door.
The label shows the size of your original tires and
the ination pressures needed to obtain the gross
weight capacity of your vehicle. This is called the
Gross Vehicle Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all occupants,
fuel, and cargo.
The Certication/Tire label also tells you the
maximum weights for the front and rear axles,
called the Gross Axle Weight Rating (GAWR).To nd out the actual loads on your front and rear
axles, you need to go to a weigh station and weigh
your vehicle. Your dealer can help you with this. Be
sure to spread out your load equally on both sides
of the centerline.
Never exceed the GVWR for your vehicle or the
GAWR for either the front or rear axle.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it can
change the way your vehicle handles.
These could cause you to lose control and
crash. Also, overloading can shorten the
life of your vehicle.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
273

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.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.
Towing
Towing Your Vehicle
Consult your dealer or a professional towing
service if you need to have your disabled vehicle
towed. SeeRoadside Assistance Program on
page 418.
If you want to tow your vehicle behind another
vehicle for recreational purposes (such as behind
a motorhome), see “Recreational Vehicle
Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your
vehicle behind another vehicle — such as behind a
motorhome. The two most common types of
recreational vehicle towing are known as “dinghy
towing” (towing your vehicle with all four wheels
on the ground) and “dolly towing” (towing
your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).
274

With the proper preparation and equipment, many
vehicles can be towed in these ways. See
“Dinghy Towing” and “Dolly Towing,” following.
Here are some important things to consider before
you do recreational vehicle towing:
What is the towing capacity of the towing
vehicle? Be sure you read the tow vehicle
manufacturer’s recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they
can tow.
Do you have the proper towing equipment?
See your dealer or trailering professional
for additional advice and equipment
recommendations.
Is your vehicle ready to be towed? Just as
you would prepare your vehicle for a long
trip, you will want to make sure your vehicle is
prepared to be towed. SeeBefore Leaving
on a Long Trip on page 260.
Dinghy Towing
You may dinghy tow your vehicle from the front
following these steps:
1. Set the parking brake.
2. Turn the ignition key to ACC to unlock the
steering wheel.
3. Shift your transaxle to NEUTRAL (N).
4. Release the parking brake.
275

To prevent the battery from draining while the
vehicle is being towed, remove the following fuse
from the oor console fuse block: 8 (Ignition
Switch, PASS-Key
®III+). SeeFloor Console Fuse
Block on page 381for more information.
Remember to reinstall the fuse once you have
reached your destination.
Notice:If you exceed 65 mph (105 km/h) while
towing your vehicle, it could be damaged.
Never exceed 65 mph (105 km/h) while towing
your vehicle.
Notice:Towing your vehicle from the rear
could damage it. Also, repairs would not
be covered by the warranty. Never have your
vehicle towed from the rear.
Dolly Towing
Your vehicle cannot be dolly towed, but can be
dinghy towed. See “Dinghy Towing” earlier in this
section.
Notice:Dolly towing your vehicle may cause
damage because of reduced ground
clearance. Always tow your vehicle using the
dinghy towing procedure listed in this
section or put your vehicle on a atbed truck.
Towing a Trailer (Manual Transaxle)
Do not tow a trailer if your vehicle is equipped
with a manual transaxle.
276

Towing a Trailer
(Automatic Transaxle)
{CAUTION:
If you do not use the correct equipment
and drive properly, you can lose control
when you pull a trailer. For example, if the
trailer is too heavy, the brakes may not
work well — or even at all. You and your
passengers could be seriously injured.
You may also damage your vehicle; the
resulting repairs would not be covered by
your warranty. Pull a trailer only if you
have followed all the steps in this section.
Ask your dealer for advice and
information about towing a trailer with
your vehicle.
Your vehicle can tow a trailer if it is equipped with
an automatic transaxle and the proper trailer
towing equipment. If your vehicle is not equipped
as stated above, do not tow a trailer. To identifythe trailering capacity of your vehicle, you should
read the information in “Weight of the Trailer”
that appears later in this section. Trailering
is different than just driving your vehicle by itself.
Trailering means changes in handling,
acceleration, braking, cooling, durability and fuel
economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That is the reason for this part. In it are many
time-tested, important trailering tips and safety
rules. Many of these are important for your safety
and that of your passengers. So please read
this section carefully before you pull a trailer.
Load-pulling components such as the engine,
transaxle, wheel assemblies and tires are forced
to work harder against the drag of the added
weight. The engine is required to operate
at relatively higher speeds and under greater
loads, generating extra heat. Also, the trailer adds
considerably to wind resistance, increasing the
pulling requirements.
277

If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed
limit restrictions, having to do with trailering.
Make sure your rig will be legal, not only where
you live but also where you will be driving.
A good source for this information can be state
or provincial police.
Consider using a sway control. You can ask a
hitch dealer about sway controls.
Do not tow a trailer at all during the rst
1,000 miles (1 600 km) your new vehicle
is driven. Your engine, axle or other parts
could be damaged.
Then, during the rst 500 miles (800 km) that
you tow a trailer, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps your engine and other parts
of your vehicle wear in at the heavier loads.
Obey speed limit restrictions when towing a
trailer. Do not drive faster than the maximum
posted speed for trailers, or no more than
55 mph (90 km/h), to save wear on your
vehicle’s parts.
Do not tow when the outside air temperature
is above 100°F (38°C).
Do not tow more than 1,000 miles (1 600 km)
per year.
Three important considerations have to do with
weight:
The weight of the trailer
The weight of the trailer tongue
The total weight on your vehicle’s tires
278

Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs
(450 kg). But even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to
pull a trailer are all important. It can also depend
on any special equipment that you have on
your vehicle, and the amount of tongue weight the
vehicle can carry. See “Weight of the Trailer
Tongue” later in this section for more information.
Maximum trailer weight is calculated assuming
only the driver is in the tow vehicle and it has all
the required trailering equipment. The weight
of additional optional equipment, passengers and
cargo in the tow vehicle must be subtracted
from the maximum trailer weight.
You can ask your dealer for our trailering
information or advice, or you can write us at our
Customer Assistance Offices. SeeCustomer
Assistance Offices on page 416for more
information.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total
or gross weight of your vehicle. The Gross Vehicle
Weight (GVW) includes the curb weight of the
vehicle, any cargo you may carry in it, and
the people who will be riding in the vehicle. If you
have a lot of options, equipment, passengers,
or cargo in your vehicle, it will reduce the tongue
weight your vehicle can carry, which will also
reduce the trailer weight your vehicle can tow.
And if you tow a trailer, you must add the tongue
load to the GVW because your vehicle will be
carrying that weight, too. SeeLoading Your
Vehicle on page 269for more information about
your vehicle’s maximum load capacity.
279

If you are using a weight-carrying hitch, the trailer
tongue (A) should weigh 10 to 15 percent of
the total loaded trailer weight (B).
After you have loaded your trailer, weigh the trailer
and then the tongue, separately, to see if the
weights are proper. If they are not, you may be
able to get them right simply by moving some
items around in the trailer.
Trailering may be limited by the vehicle’s ability to
carry tongue weight. Tongue weight cannot
cause the vehicle to exceed the GVWR (Gross
Vehicle Weight Rating) or the RGAWR (Rear
Gross Axle Weight Rating). The effect of additional
weight may reduce your trailering capacity more
than the total of the additional weight.Consider the following example:
A vehicle model base weight is 5,500 lbs
(2 495 kg); 2,800 lbs (1 270 kg) at the front axle
and 2,700 lbs (1 225 kg) at the rear axle. It
has a GVWR of 7,200 lbs (3 266 kg), a RGAWR
of 4,000 lbs (1 814 kg) and a GCWR (Gross
Combination Weight Rating) of 14,000 lbs
(6 350 kg). The trailer rating should be:
You can expect tongue weight to be at least
10 percent of trailer weight (850 lbs (386 kg)) and
because the weight is applied well behind the
rear axle, the effect on the rear axle will be greater
than just the weight itself, as much as 1.5 times
as much. The weight at the rear axle could
be 850 lbs (386 kg) X 1.5 = 1,275 lbs (578 kg).
Since the rear axle already weighs 2,700 lbs
(1 225 kg), adding 1,275 lbs (578 kg) brings the
