148 Lighting
When the ignition is on, illuminated
entry is inactive, which means the
courtesy lamps will not come on
unless a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates
the interior for a period of time after
all the doors have been closed.
The ignition must be off for delayed
entry lighting to work. Immediately
after all the doors have been closed,
the delayed entry lighting feature
continues to work until one of the
following occurs:
.The ignition is in ON/RUN.
. The doors are locked.
. An illumination period of about
25 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period is canceled and
the interior lamps remain on.
Delayed Exit Lighting
Delayed exit lighting illuminates the
interior for a period of time after the
key is removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the key
is removed, interior illumination
activates and remains on until one
of the following occurs:
. The ignition is in ON/RUN.
. The power door locks are
activated.
. An illumination period of
20 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period will be canceled
and the interior lamps will remain on
because a door is open.
Parade Dimming
This feature automatically prohibits
the dimming of the instrument panel
displays in daylight while the
headlamps are on so that the
displays are still able to be seen.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the
power needed for very high
electrical loads.

function along with the inside
temperature setting. The outside
temperature is displayed on the
instrument cluster.
(:Turn clockwise or
counterclockwise to turn the climate
control system on or off.
The climate control system will also
turn on if the defrost, AUTO, or air
conditioning buttons are pressed.
Automatic Operation
The system automatically controls
the fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to
the desired temperature.
When AUTO is lit, all four functions
operate automatically. Each function
can also be manually set and the
setting is displayed. Functions not
manually set will continue to be
automatically controlled, even if the
AUTO indicator is not lit. For automatic operation:
1. Press AUTO.
When AUTO is selected, the
current temperature(s) is
displayed and the AUTO
indicator light is on.
When AUTO is selected, the
air conditioning and air inlet are
automatically controlled. The

C (40 °F). The system is
automatically set to outside air,
unless it is hot outside and
then the air inlet changes to
recirculation mode to help
quickly cool the vehicle. The
recirculation indicator light will
come on.
2. Set the temperature for the driver and passenger.
To find a comfortable setting,
start with a 22 °C (73 °F)
temperature setting and allow
about 20 minutes for the
system to regulate. Use the
driver side or passenger side
temperature control to adjust the temperature setting as
necessary. The system will
remain at the selected setting.
Choosing the warmest or
coolest temperatures does not
cause the vehicle to heat or
cool more quickly.
To avoid blowing cold air in
cold weather, the system
delays turning on the fan until
warm air is available. Turn the
fan knob to override this delay
and select the fan speed.
Temperature Control
The driver and passenger side
temperature controls are used to
adjust the temperature of the air
coming through the system. The

Driving and Operating 163
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
for more than 15 seconds,
damage may occur to the power
steering system and there may be
loss of power steering assist.
Curve Tips
.Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable, steady
speed through the curve.
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.
There are some situations when
steering around a problem may
be more effective than braking. .
Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. Antilock Brake System (ABS)
allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
1. Ease off the accelerator and then, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —
too much speed or steering in a
curve causes tires to slip and
lose cornering force.

GMC Acadia Limited Owner Manual (GMNA-Localizing-U.S.-10283134) -
2017 - crc - 3/31/16
164 Driving and Operating
.Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
. Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
. Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues —such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt. .
Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle. (Continued)
Warning (Continued)
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
