wheel BUICK ENCLAVE 2009 Service Manual

Try not to break the fragile traction. If
you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
TheStabiliTrak
®System on page 4-5
improves the ability to accelerate on
slippery roads, but slow down and
adjust your driving to the road
conditions. When driving through
deep snow, turn off the traction
control part of the StabiliTrak
®
System to help maintain vehicle
motion at lower speeds.
TheAntilock Brake System (ABS)
on page 4-4improves vehicle
stability during hard stops on a
slippery roads, but apply the brakes
sooner than when on dry pavement.
Allow greater following distance
on any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of
a curve or an overpass can remain
icy when the surrounding roads
are clear. Avoid sudden steering
maneuvers and braking while on ice.Turn off cruise control, if equipped,
on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program on page 7-6.
To get help and keep everyone
in the vehicle safe:
Turn on theHazard Warning
Flashers on page 3-5.
Tie a red cloth to an outside
mirror.
{CAUTION
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside.
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
Clear away snow from
around the base of your
vehicle, especially any that is
blocking the exhaust pipe.
Check again from time to
time to be sure snow does
not collect there.
Open a window about two
inches (5 cm) on the side of
the vehicle that is away from
the wind to bring in fresh air.
Fully open the air outlets on or
under the instrument panel.

CAUTION (Continued)
Adjust the Climate Control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in
the Index.
For more information about
carbon monoxide, seeEngine
Exhaust on page 2-30.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (carbon
monoxide) gas to get inside. CO
could overcome you and kill you.
You cannot see it or smell it, so
you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.
Run the engine for short periods
only as needed to keep warm,
but be careful.To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat
this until help arrives but only when
you feel really uncomfortable
from the cold. Moving about to keep
warm also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine
runs faster than the idle speed. This
keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do
this as little as possible to save fuel.
If Your Vehicle is Stuck
in Sand, Mud, Ice,
or Snow
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It
Out on page 4-16.If the vehicle has a traction system,
it can often help to free a stuck
vehicle. Refer to the vehicle’s
traction system in the Index. If stuck
too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{CAUTION
If you let your vehicle’s tires spin
at high speed, they can explode,
and you or others could be
injured. The vehicle can overheat,
causing an engine compartment
re or other damage. Spin the
wheels as little as possible and
avoid going above 35 mph
(55 km/h) as shown on the
speedometer.
For information about using tire
chains on the vehicle, seeTire
Chains on page 5-56.
Driving Your Vehicle 4-15

Rocking Your Vehicle to
Get It Out
Turn the steering wheel left and
right to clear the area around
the front wheels. Turn off any
traction or stability system. Shift
back and forth between R (Reverse)
and a forward gear, spinning the
wheels as little as possible. To
prevent transmission wear, wait until
the wheels stop spinning before
shifting gears. Release the
accelerator pedal while shifting, and
press lightly on the accelerator
pedal when the transmission is in
gear. Slowly spinning the wheels in
the forward and reverse directions
causes a rocking motion that
could free the vehicle. If that does
not get the vehicle out after a
few tries, it might need to be towed
out. If the vehicle does need to
be towed out, seeTowing Your
Vehicle on page 4-21.
Loading the Vehicle
It is very important to know how
much weight your vehicle can
carry. This weight is called
the vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on your vehicle show
how much weight it may
properly carry, the Tire and
Loading Information label and
the Certication/Tire label.{CAUTION
Do not load the 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
the 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 the vehicle.
4-16 Driving Your Vehicle

Towing
Towing Your Vehicle
To avoid damage, the disabled
vehicle should be towed with all
four wheels off the ground. Consult
your dealer/retailer or a professional
towing service if the disabled vehicle
must be towed. SeeRoadside
Assistance Program on page 7-6.
To tow the 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 the vehicle behind another
vehicle – such as behind a
motorhome. The two most common
types of recreational vehicle towing
are known as “dinghy towing” (towing
the vehicle with all four wheels on the
ground) and “dolly towing” (towingthe vehicle with two wheels on the
ground and two wheels up on a
device known as a “dolly”).
Here are some important things to
consider before recreational
vehicle towing:
What is the towing capacity of the
towing vehicle? Be sure to read
the tow vehicle manufacturer’s
recommendations.
What is the distance that will be
travelled? Some vehicles have
restrictions on how far and how
long they can tow.
Is the proper towing equipment
going to be used? See your
dealer/retailer or trailering
professional for additional advice
and equipment recommendations.
Is the vehicle ready to be towed?
Just as preparing the vehicle for a
long trip, make sure the vehicle is
prepared to be towed. SeeBefore
Leaving on a Long Trip on
page 4-12.
Dinghy Towing
If the vehicle is front-wheel-drive, it
can be dinghy towed from the
front. These vehicles may also be
towed by putting the front wheels on
a dolly. See “Dolly Towing” later
in this section.
If the vehicle is all-wheel-drive, it
can be dinghy towed from the front.
These vehicles can also be towed by
placing them on a platform trailer
with all four wheels off of the ground.
These vehicles cannot be towed
using a dolly.
Driving Your Vehicle 4-21

For vehicles being dinghy towed,
the vehicle should be run at
the beginning of each day and at
each RV fuel stop for about
ve minutes. This will ensure proper
lubrication of transmission
components. Re-install the fuse to
start the vehicle.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to tow and
then secure it to the towing
vehicle.
2. Shift the transmission to P (Park)
and turn the ignition to
LOCK/OFF.
3. Set the parking brake.
4. Turn the ignition to
ACC/ACCESSORY.
5. Shift the transmission to
N (Neutral).6. To prevent the battery from
draining while the vehicle is being
towed, remove the 50 amp
BATT1 fuse from the underhood
fuse block and store in a safe
location. SeeUnderhood
Fuse Block on page 5-94.
7. Release the parking brake.
Notice:If the vehicle is towed
without performing each of
the steps listed under “Dinghy
Towing,” the automatic
transmission could be damaged.
Be sure to follow all steps of
the dinghy towing procedure prior
to and after towing the vehicle.
Notice:If 65 mph (105 km/h)
is exceeded while towing
the vehicle, it could be damaged.
Never exceed 65 mph (105 km/h)
while towing the vehicle.Once the destination is reached:
1. Set the parking brake.
2. Reinstall the 50 amp BATT1 fuse
to the underhood fuse block.
3. Shift the transmission to P (Park),
turn the ignition to LOCK/OFF
and remove the key from
the ignition.
4. Disconnect the vehicle from the
towing vehicle.
Notice:Do not tow a vehicle
with the front drive wheels on the
ground if one of the front tires
is a compact spare tire. Towing
with two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.
4-22 Driving Your Vehicle

Dolly Towing (All-Wheel-Drive
Vehicles)
All-wheel-drive vehicles must not
be towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on a
platform trailer with all four wheels off
of the ground or dinghy towed from
the front.
Dolly Towing
(Front-Wheel-Drive
Vehicles Only)
To tow a front-wheel-drive vehicle
from the front with two wheels
on the ground:
1. Put the front wheels on a dolly.
2. Move the shift lever to P (Park).3. Set the parking brake.
4. Clamp the steering wheel in a
straight-ahead position with a
clamping device designed
for towing.
5. Remove the key from the
ignition.
6. Secure the vehicle to the dolly.
7. Release the parking brake.
Driving Your Vehicle 4-23

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.

*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and
trailer including any passengers, cargo, equipment and conversions. The GCWR for the vehicle should not be
exceeded.
Ask your dealer/retailer for our
trailering information or advice, or
write us at our Customer Assistance
Offices. See Customer Assistance
Offices on page 7-4 for 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 gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo carried in it, and the people
who will be riding in the vehicle.
If there are a lot of options,
equipment, passengers or cargo in the vehicle, it will reduce the tongue
weight the vehicle can carry,
which will also reduce the trailer
weight the vehicle can tow. If towing
a trailer, the tongue load must be
added to the GVW because
the vehicle will be carrying that
weight, too. See
Loading the Vehicle
on page 4-16 for more information
about the vehicle’s maximum
load capacity.
If a weight-carrying hitch or a
weight-distributing hitch is being
used, the trailer tongue (A) should
weigh 10-15 percent of the total
loaded trailer weight (B).
Driving Your Vehicle 4-27

Safety Chains
Always attach chains between the
vehicle and the trailer. Cross
the safety chains under the tongue
of the trailer to help prevent the
tongue from contacting the road if it
becomes separated from the
hitch. Instructions about safety
chains may be provided by the hitch
manufacturer or by the trailer
manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains and do
not attach them to the bumper.
Always leave just enough slack so
the rig can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
A loaded trailer that weighs more
than 1,000 lbs (450 kg) needs
to have its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted
and maintained properly.Because the vehicle has antilock
brakes, do not try to tap into
the vehicle’s hydraulic brake system.
If you do, both brake systems will
not work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Get to
know the rig before setting out for
the open road. Get acquainted
with the feel of handling and braking
with the added weight of the
trailer. And always keep in mind that
the vehicle you are driving is now
longer and not as responsive as the
vehicle is by itself.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirror adjustments. If the
trailer has electric brakes, start the
vehicle and trailer moving and then
apply the trailer brake controller by
hand to be sure the brakes are
working. This checks the electrical
connection at the same time.During the trip, check occasionally
to be sure that the load is secure,
and that the lamps and any
trailer brakes are still working.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations that
require heavy braking and sudden
turns.
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.
4-30 Driving Your Vehicle

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.
SeeScheduled Maintenance on
page 6-3for 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.
