2009 CHEVROLET TRAVERSE engine

Towing a Trailer
{CAUTION
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly. For
example, if the trailer is too heavy,
the brakes may not work well — or
even at all. The driver and
passengers could be seriously
injured. The vehicle may also be
damaged; the resulting repairs
would not be covered by the
vehicle warranty. Pull a trailer only
if all the steps in this section have
been followed. Ask your dealer/
retailer for advice and information
about towing a trailer with the
vehicle.To identify the trailering capacity of
the vehicle, read the information
in “Weight of the Trailer” that
appears later in this section.
Trailering is different than just driving
the vehicle by itself. Trailering means
changes in handling, acceleration,
braking, durability and fuel economy.
Successful, safe trailering takes
correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering tips
and safety rules. Many of these are
important for the safety of the driver
and the passengers. So please read
this section carefully before pulling
a trailer.Load-pulling components such as
the engine, transmission, rear axle,
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. What’s
more, the trailer adds considerably
to wind resistance, increasing the
pulling requirements.

Pulling A Trailer
Here are some important points:
There are many different laws,
including speed limit restrictions,
having to do with trailering. Make
sure the 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.
See “Hitches” later in this section.
Do not tow a trailer at all during
the rst 500 miles (800 km) the
new vehicle is driven. The engine,
axle or other parts could be
damaged.
Then, during the rst 500 miles
(800 km) that a trailer is towed, do
not drive over 50 mph (80 km/h)
and do not make starts at full
throttle. This helps the engine and
other parts of the vehicle wear in
at the heavier loads.
Obey speed limit restrictions
when towing a trailer.
The vehicles can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts too
often under heavy loads and/or
hilly conditions. See “Tow/Haul
Mode” later in this section.
The vehicle is designed primarily
as a passenger and load carrying
vehicle. If a trailer is towed,
the vehicle will require more
frequent maintenance due to the
additional load.
Three important considerations have
to do with weight:
The weight of the trailer.
The weight of the trailer tongue.
And the weight on the vehicle’s
tires
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how the rig is used.
For example, speed, altitude, road
grades, outside temperature and
how much the vehicle is used to pull
a trailer are all important. It can
depend on any special equipment on
the 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.
Use the following chart to determine
how much the vehicle can weigh,
based upon the vehicle model and
options.
4-26 Driving Your Vehicle

You may go further and think the
tongue weight should be limited
to less than 1,000 lbs (454 kg) to
avoid exceeding GVWR. But the
effect on the rear axle must still be
considered. Because the rear axle
now weighs 3,100 lbs (1 406 kg),
900 lbs (408 kg) can be put on
the rear axle without exceeding
RGAWR. The effect of tongue weight
is about 1.5 times the actual weight.
Dividing the 900 lbs (408 kg) by 1.5
leaves only 600 lbs (272 kg) of
tongue weight that can be handled.
Since tongue weight is usually at
least 10 percent of total loaded trailer
weight, expect that the largest trailer
the vehicle can properly handle is
6,000 lbs (2 721 kg).It is important that the vehicle
does not exceed any of its
ratings — GCWR, GVWR, RGAWR,
Maximum Trailer Rating or Tongue
Weight. The only way to be sure it is
not exceeding any of these ratings is
to weigh the vehicle and trailer.
Total Weight on the Vehicle’s
Tires
Be sure the vehicle’s tires are
inated to the upper limit for cold
tires. These numbers can be found
on the Certication/Tire label. See
Loading the Vehicle on page 4-16.
Make sure not to go over the GVW
limit for the vehicle, including the
weight of the trailer tongue.
Hitches
It is important to have the correct
hitch equipment. Crosswinds, large
trucks going by and rough roads are
a few reasons why the right hitch is
needed. Here are some rules to
follow:
The rear bumper on the vehicle is
not intended for hitches. Do not
attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If there
are, then be sure to seal the holes
later when the hitch is removed.
If the holes are not sealed, dirt,
water, and deadly carbon
monoxide (CO) from the exhaust
can get into the vehicle. See
Engine Exhaust on page 2-30.

Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the lane.
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move the
trailer to the left, move that hand to
the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and, if
possible, have someone guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.When turning with a trailer, make
wider turns than normal. Do this so
the trailer won’t strike soft shoulders,
curbs, road signs, trees or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
ash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also ash, telling
other drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument panel ash for turns
even if the bulbs on the trailer are
burned out. For this reason you may
think other drivers are seeing the
signal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving on Grades
Because of the added load of the
trailer, the vehicle’s engine may
overheat on hot days, when going up
a long or steep grade with a trailer. If
the engine coolant temperature gage
indicates overheating, turn off the air
conditioning to reduce engine load,
pull off the road and stop in a safe
spot. Let the engine run while
parked, preferably on level ground,
with the transmission in P (Park) for
a few minutes before turning the
engine off.
Reduce speed and shift to a lower
gearbeforestarting down a long or
steep downgrade. If the transmission
is not shifted down, the brakes
might have to be used so much that
they would get hot and no longer
work well.
On a long uphill grade, shift down
and reduce the vehicle speed
to around 55 mph (88 km/h) to
reduce the possibility of the engine
and the transmission overheating.

Tow/Haul Mode
Tow/Haul is a feature that assists
when pulling a heavy trailer or
a large or heavy load. The purpose
of the Tow/Haul mode is to:
Reduce the frequency and
improve the predictability of
transmission shifts when pulling
a heavy trailer or a large or
heavy load.
Provide the same solid shift feel
when pulling a heavy trailer or a
large or heavy load as when
the vehicle is unloaded.
Improve control of vehicle speed
while requiring less throttle pedal
activity when pulling a heavy
trailer or a large or heavy load.
Increase the charging system
voltage to assist in recharging
a battery installed in a trailer.Press this button located on the
console to turn on and turn off the
Tow/Haul mode.
The Tow/Haul light on the instrument
panel will come on to indicate that
Tow/Haul mode has been selected.
Tow/Haul may be turned off by
pressing the button again, at which
time the indicator light on the
instrument panel will turn off. The
vehicle will automatically turn off
Tow/Haul every time it is started.
Tow/Haul is designed to be most
effective when the vehicle and
trailer combined weight is at least
75 percent of the vehicle’s Gross
Combined Weight Rating (GCWR).See Weight of the Trailer earlier in
this section. Tow/Haul is most useful
under the following driving
conditions:
When pulling a heavy trailer or a
large or heavy load through rolling
terrain.
When pulling a heavy trailer or a
large or heavy load in stop and go
traffic.
When pulling a heavy trailer
or a large or heavy load in busy
parking lots where improved low
speed control of the vehicle is
desired.
Operating the vehicle in Tow/Haul
when lightly loaded or with no
trailer at all will not cause damage.
However, there is no benet to the
selection of Tow/Haul when the
vehicle is unloaded. Such a selection
when unloaded may result in
unpleasant engine and transmission
driving characteristics and reduced
fuel economy. Tow/Haul is
recommended only when pulling a
heavy trailer or a large or heavy load.

Parking on Hills
{CAUTION
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a at surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not
shift into P (Park) yet. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks
under the trailer wheels.3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then
apply the parking brake and shift
the transmission into P (Park).
5. Release the brake pedal.
Leaving After Parking on
a Hill
1. Apply and hold the brake pedal
while you:
start the engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is
clear of the chocks.
4. Stop and have someone pick up
and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See
Scheduled Maintenance on page 6-3
for more information. Things that
are especially important in trailer
operation are automatic transmission
uid, engine oil, axle lubricant, belts,
cooling system and brake system.
It is a good idea to inspect these
before and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Trailer Wiring Harness
The vehicle is equipped with the
following wiring harness for towing
a trailer.
Driving Your Vehicle 4-33

Basic Trailer Wiring
The trailer wiring harness, with a
seven-pin connector, is located at
the rear of the vehicle and is tied to
the vehicle’s frame. The harness
connector can be plugged into a
seven-pin universal heavy-duty
trailer connector available through
your dealer/retailer.
The seven-wire harness contains
the following trailer circuits:
Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn
Signal
Brown: Taillamps
Black: Ground
Light Green: Back-up Lamps
Red/Black: Battery Feed
Dark Blue: Trailer Brake*
*The fuse for this circuit is installed
in the underhood electrical center,
but the wires are not connected.They should be connected by your
dealer/retailer or a qualied
service center.
If the back-up lamp circuit is not
functional, contact your
dealer/retailer.
If a remote (non-vehicle) battery is
being charged, press the Tow/Haul
mode switch located on the center
console near the climate controls.
This will boost the vehicle system
voltage and properly charge the
battery. If the trailer is too light
for Tow/Haul mode, turn on the
headlamps (Non-HID only) as a
second way to boost the vehicle
system and charge the battery.
Electric Trailer Brake Control
Wiring Provisions
These wiring provisions for an
electric trailer brake controller
are included with the vehicle as
part of the trailer wiring package.The instrument panel contains blunt
cut wires behind the steering column
for the electric trailer brake controller.
The harness contains the following
wires:
Red/Black: Power Supply
White: Brake Switch Signal
Gray: Illumination
Dark Blue: Trailer Brake Signal
Black: Ground
The electric trailer brake controller
should be installed by your dealer/
retailer or a qualied service center.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. SeeEngine Overheating
on page 5-22.
