BUICK ENCLAVE 2010 Owner's Manual

Driving and Operating 9-29
will be displayed on the Driver
Information Center (DIC):
TRACTION CONTROL OFF,
SERVICE TRACTION CONTROL,
SERVICE STABILITRAK. If these
conditions are observed, turn the
vehicle off, wait 15 seconds, and
then turn it back on again to reset
the system. If any of these
messages still appear on the Driver
Information Center (DIC), the
vehicle should be taken in for
service. For more information on the
DIC messages, seeDriver
Information Center (DIC)
on
page 5‑25.
The StabiliTrak light will flash on the
instrument panel cluster when the
system is both on and activated.
The system may be heard or felt
while it is working; this is normal.
The traction control disable button is
located on the instrument panel
below the climate controls.
The traction control part of
StabiliTrak can be turned off by
pressing and releasing the traction
control disable button.
Traction control can be turned on by
pressing and releasing the traction
control disable button if not
automatically shut off for any other
reason.
When the traction control system is
turned off, the StabiliTrak light and
the appropriate traction control off
message will be displayed on the
DIC to warn the driver. The vehicle
will still have brake-traction control
when traction control is off, but will
not be able to use the engine speed management system. See
“Traction
Control Operation” next for more
information.
When the traction control system
has been turned off, system noises
may be heard and felt as a result of
the brake-traction control working.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle
is stuck in sand, mud, ice or snow,
and you want to “rock”the vehicle to
attempt to free it. It may also be
necessary to turn off the system
when driving in extreme off-road
conditions where high wheel spin is
required. See If the Vehicle is Stuck
on page 9‑11.
Traction Control Operation
The traction control system is part of
the StabiliTrak system. Traction
control limits wheel spin by
reducing engine power to the
wheels (engine speed management)

9-30 Driving and Operating
and by applying brakes to each
individual wheel (brake-traction
control) as necessary.
The traction control system is
enabled automatically when the
vehicle is started. It will activate and
the StabiliTrak light will flash if it
senses that any of the wheels are
spinning or beginning to lose
traction while driving. If traction
control is turned off, only the
brake-traction control portion of
traction control will work. The
engine speed management will be
disabled. In this mode, engine
power is not reduced automatically
and the driven wheels can spin
more freely. This can cause the
brake-traction control to activate
constantly.
Notice:If the wheel(s) of one axle
is allowed to spin excessively
while the StabiliTrak, ABS and
brake warning lights and any
relevant DIC messages are
displayed, the transfer case could
be damaged. The repairs would not be covered by the vehicle
warranty. Reduce engine power
and do not spin the wheel(s)
excessively while these lights and
messages are displayed.
The traction control system may
activate on dry or rough roads or
under conditions such as heavy
acceleration while turning or abrupt
upshifts/downshifts of the
transmission. When this happens, a
reduction in acceleration may be
noticed, or a noise or vibration may
be heard. This is normal.
If cruise control is being used when
the system activates, the StabiliTrak
light will flash and cruise control will
automatically disengage. Cruise
control may be reengaged when
road conditions allow. See
Cruise
Control on page 9‑30.
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system.
If the problem does not clear itself
after restarting the vehicle, see your
dealer/retailer for service.Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
When the brakes are applied, the
cruise control is disengaged.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.

Driving and Operating 9-31

9-32 Driving and Operating
Increasing Speed While Using
Cruise Control
There are two ways to increase the
vehicle speed while using cruise
control:
.Press and hold the +RES button
on the steering wheel until the
desired speed is reached, then
release it.
.To increase vehicle speed in
small increments, press the
+RES button briefly. Each time
this is done, the vehicle goes
about 1.6 km/h (1 mph) faster.
Reducing Speed While Using
Cruise Control
There are two ways to reduce the
vehicle speed while using cruise
control:
.Press and hold the SET– button
on the steering wheel until the
lower speed desired is reached,
then release it.
.To slow down in very small
amounts, press the SET– button
briefly. Each time this is done,
the vehicle goes about 1.6 km/h
(1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase vehicle speed. When you
take your foot off the pedal, the
vehicle will slow down to the
previously set cruise speed.
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to keep the
vehicle speed down. When the
brakes are applied the cruise control
is disengaged. Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal.
.Press the[button.
.Press theTbutton.
Erasing Speed Memory
The cruise control set speed
memory is erased when the cruise
control or the ignition is turned off.

Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it operates at speeds less than
8 km/h (5 mph), and assists the
driver with parking and avoiding
objects while in R (Reverse). The
sensors on the rear bumper are
used to detect the distance to an
object up to 2.5 m (8 ft) behind the
vehicle, and at least 25.4 cm (10 in)
off the ground.
{WARNING
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
.objects that are below the
bumper, underneath the
vehicle, or if they are too
close or far from the vehicle
.children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before and while backing; vehicle
damage, injury, or death could
occur. Even with URPA, always
check behind the vehicle before
backing up. While backing, be
sure to look for objects and check
the vehicle's mirrors.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 5 mph (8 km/h).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeps are
continuous.
To be detected, objects must be at
least 25.4 cm (10 in) off the ground
and below liftgate level. Objects
must also be within 2.5 m (8 ft) from
the rear bumper. This distance may
be less during warmer or humid
weather.
The system can be disabled through
the Driver Information Center (DIC).
See “Park Assist” underVehicle
Personalization
on page 5‑40for
more information.

9-34 Driving and Operating
When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message PARK
ASSIST OFF displays on the DIC
when the shift lever is moved into
R (Reverse). This may occur under
the following conditions:
.The driver disables the system.
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice and slush. For cleaning
instructions, seeExterior Care
on page 10‑88.
.A trailer was attached to the
vehicle, or a bicycle or an object
was hanging out of the liftgate
during the last drive cycle. Once
the attached object is removed,
URPA will return to normal
operation.
.A tow bar is attached to the
vehicle.
.The vehicle's bumper is
damaged. Take the vehicle to
your dealer/retailer to repair the
system.
.Other conditions may affect
system performance, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck.
If the system is still disabled, after
driving forward at least 25 km/h
(15 mph), take the vehicle to your
dealer/retailer.
Rear Vision
Camera (RVC)
The vehicle may have a Rear Vision
Camera system. Read this entire
section before using it.
{WARNING
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
.Detect objects that are
outside the camera's field of
view, below the bumper,
or underneath the vehicle.
.Detect children, pedestrians,
bicyclists, or pets.
Do not back the vehicle by only
looking at the RVC screen, or use
the screen during longer, higher
speed backing maneuvers or
where there could be cross-traffic. (Continued)

Driving and Operating 9-35
WARNING (Continued)
Your judged distances using the
screen will differ from actual
distances.
So if you do not use proper care
before backing up, you could hit a
vehicle, child, pedestrian,
bicyclist, or pet, resulting in
vehicle damage, injury, or death.
Even though the vehicle has the
RVC system, always check
carefully before backing up by
checking behind and around the
vehicle.
