instrument cluster light will come
on to indicate the IntelliBeam
system is reactivated.
The high beams may not turn off
automatically if the system cannot
detect another vehicle's lamps
because of any of the following:
. The other vehicle's lamps are
missing, damaged, obstructed
from view, or otherwise
undetected.
. The other vehicle's lamps are
covered with dirt, snow, and/or
road spray.
. The other vehicle's lamps cannot
be detected due to dense
exhaust, smoke, fog, snow, road
spray, mist, or other airborne
obstructions.
. The vehicle's windshield is dirty,
cracked, or obstructed by
something that blocks the view
of the light sensor. .
The vehicle is loaded such that
the front end points upward,
causing the light sensor to aim
high and not detect headlamps
and taillamps.
. The vehicle is being driven on
winding or hilly roads.
The IntelliBeam system may need to
be disabled if any of the above
conditions exist.

Driving Information
Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local
governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, always
keep your eyes on the road, hands
on the wheel, and mind on the drive.
. Do not use a phone in
demanding driving situations.
Use a hands-free method to
place or receive necessary
phone calls.
. Watch the road. Do not read,
take notes, or look up
information on phones or other
electronic devices. .
Designate a front seat
passenger to handle potential
distractions.
. Become familiar with vehicle
features before driving, such as
programming favorite radio
stations and adjusting climate
control and seat settings.
Program all trip information into
any navigation device prior to
driving.
. Wait until the vehicle is parked
to retrieve items that have fallen
to the floor.
. Stop or park the vehicle to tend
to children.
. Keep pets in an appropriate
carrier or restraint.
. Avoid stressful conversations
while driving, whether with a
passenger or on a cell phone.

196 Driving and Operating
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. SeeTraction
Control/Electronic Stability Control
0 220.
{Warning
If the 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 fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Select All-Wheel Drive (AWD)
Mode.
See Driver Mode Control 0222 and
All-Wheel Drive 0216.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a low
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,
see Towing the Vehicle 0327.
Vehicle Load Limits
It is very important to know how
much weight the 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 the vehicle may
show how much weight it may
properly carry, the Tire and
Loading Information label and
the Certification/Tire label.
{Warning
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).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.

Tire and Loading Information
Label
Example Label
A vehicle-specific Tire and
Loading Information label is
attached to the center pillar
(B-pillar). The tire and loading
information label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
size of the original equipmenttires (3) and the recommended
cold tire inflation pressures (4).
For more information on tires
and inflation see
Tires0295
and Tire Pressure 0302.
There is also important loading
information on the vehicle
Certification/Tire label. It may
show the Gross Vehicle Weight
Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for
the front and rear axle. See
“Certification/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 figure equals
the available amount of
cargo and luggage load
capacity. For example, if the
"XXX" amount equals
1400 lbs. and there will be
five 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, load from your
trailer will be transferred to

Buick Enclave Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
10999311) - 2018 - crc - 11/20/17

your vehicle. Consult this
manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.”
See Trailer Towing 0256 for
important information on towing
a trailer, towing safety rules and
trailering tips.
Example 1
1.Vehicle Capacity Weight
for Example 1 = 453 kg
(1,000 lbs).
2.Subtract Occupant
Weight @ 68 kg (150 lbs)
× 2 = 136 kg (300 lbs).
3.Available Occupant and
Cargo Weight = 317 kg
(700 lbs).
Example 2
1.Vehicle Capacity Weight
for Example 2 = 453 kg
(1,000 lbs).
2.Subtract Occupant
Weight @ 68 kg (150 lbs)
× 5 = 340 kg (750 lbs).
3.Available Cargo Weight
= 113 kg (250 lbs).
Example 3
1.Vehicle Capacity Weight
for Example 3 = 453 kg
(1,000 lbs).
2.Subtract Occupant
Weight @ 91 kg
(200 lbs) × 5 = 453 kg
(1,000 lbs).
3.Available Cargo Weight
= 0 kg (0 lbs).
