126 Lighting exterior lamps and dome lamps
remain on after the door is closed
for a set amount of time, then
automatically turn off.
The exterior lamps turn off
immediately by turning the exterior
lamps control off.
This feature can be changed. See
Vehicle Personalization 0 114 .
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.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, rear
window defogger, climate control fan
at high speed, heated seats, engine
cooling fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories. Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a DIC message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible. See
Driver Information Center (DIC)
0 110 .
Battery Power Protection The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery
Saver The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left

Lighting 127on. This protects against draining
the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the off position and then back to
the parking lamp or headlamp
position.
To keep the lamps on for more than
10 minutes, the ignition must be on
or in ACC/ACCESSORY.

= : Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The defogger only works when the
ignition is on. The defogger turns off
if the ignition is off or in ACC/
ACCESSORY.
The rear window defogger can be
set to automatic operation. See
“ Climate and Air Quality ” under
Vehicle Personalization 0 114 .
When Auto Rear Defog is selected,
the rear window defogger turns on
automatically when the interior
temperature is cold and the outside
temperature is about 4 °C (40 °F)
and below. The auto rear defogger
turns off automatically after about
10 minutes. At higher speeds, the
rear window defogger may stay on
continuously.
If equipped with heated outside
mirrors, they turn on when the rear
window defogger button is on and help to clear fog or frost from the
surface of the mirrors. See Heated
Mirrors 0 34 .
CautionDo not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything
else that is sharp. This may
damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.

( : If equipped, press to turn the
heated steering wheel on or off. See
Heated Steering Wheel 0 94 . Remote Start Climate Control
Operation : The climate control
system may run when the vehicle is
started remotely. The system uses
the driver ’ s previous settings to heat
or cool the inside of the vehicle. The
rear defog may come on during
remote start based on cold ambient
conditions. The rear defog indicator
light does not come on during a
remote start. If equipped with front
heated seats, they may come on
during a remote start. The heated
seat indicator lights do not come
on during a remote start.

Driving and Operating 139Other Rainy Weather Tips Besides slowing down, other wet
weather driving tips include:
.
Allow extra following distance.
.
Pass with caution.
.
Keep windshield wiping
equipment in good shape.
.
Keep the windshield washer fluid
reservoir filled.
.
Have good tires with proper
tread depth. See Tires 0 208 .
.
Turn off cruise control.
Hill and Mountain Roads Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips include:
.
Keep the vehicle serviced and in
good shape.
.
Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.
Shift to a lower gear when going
down steep or long hills. { WarningUsing the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{ WarningCoasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering assist. Always
have the engine running and the
vehicle in gear.
.
Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line. .
Be alert on top of hills;
something could be in your lane
(e.g., stalled car, accident).
.
Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving Driving on Snow or Ice Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.
Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
.
Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0 157 .

Buick Cascada Owner Manual (GMNA-Localizing-U.S-11373983) - 2018 -

Driving and Operating 145Warning (Continued).
Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats..
Do not leave an
unsecured child restraint
in the vehicle..
Secure loose items in the
vehicle..
Do not leave a seat
folded down unless
needed. Starting and
Operating New Vehicle Break-In CautionThe vehicle does not need an
elaborate break-in. But it will
perform better in the long run if
you follow these guidelines:
.
Do not drive at any one
constant speed, fast or slow,
for the first 805 km (500 mi).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
.
Avoid making hard stops for
the first 322 km (200 mi) or
so. During this time the new
brake linings are not yet
broken in. Hard stops with
new linings can mean
premature wear and earlier
replacement. Follow this
(Continued) Caution (Continued) breaking-in guideline every
time you get new brake
linings.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
The ignition switch has four different
positions.

Buick Cascada Owner Manual (GMNA-Localizing-U.S-11373983) - 2018 -
CRC - 7/10/17
146 Driving and Operating CautionUsing a tool to force the key to
turn in the ignition could cause
damage to the switch or break the
key. Use the correct key, make
sure it is all the way in, and turn it
only with your hand. If the key
cannot be turned by hand, see
your dealer.
The key must be fully extended to
start the vehicle.
To shift out of P (Park), turn the
ignition on and apply the brake
pedal.
0 : When the vehicle is stopped,
turn the ignition off to turn the
engine off. Retained Accessory
Power (RAP) will remain active. See
Retained Accessory Power (RAP)
0 148 .
This is the only position from which
the key can be removed. This locks
the ignition and automatic
transmission. Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral).
This can be done while the
vehicle is moving. After shifting
to N (Neutral), continue to
firmly apply the brakes and
steer the vehicle to a safe
location.
3. Come to a complete stop. Shift
to P (Park). Turn the
ignition off.
4. Set the parking brake. See
Electric Parking Brake 0 155 .{ WarningTurning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
turn the ignition to ACC/
ACCESSORY.
1 : This position provides power to
some of the electrical accessories.
To move the key from ACC/
ACCESSORY to off, push in the key
and then turn the ignition to off.
2 : The ignition switch stays in this
position when the engine is running.
This position can be used to operate

Driving and Operating 147malfunction indicator lamp as may
be required for emission inspection
purposes. The transmission is also
unlocked in this position.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or on position with the engine off.
The vehicle might not start if the
battery is allowed to drain for an
extended period of time.
3 : This position starts the engine.
When the engine starts, release the
key. The ignition switch will return to
on for normal driving.
A warning tone sounds when the
driver door is opened if the ignition
is still in ACC/ACCESSORY and the
key is in the ignition.
If the ignition becomes difficult to
turn, see Keys 0 21 .
Key Lock Release
The vehicle is equipped with an
electronic key lock release. The key
lock release is designed to prevent
ignition key removal unless the shift
lever is in P (Park). The key lock release is always
functional except in the case of an
uncharged or low voltage (less than
9-volt) battery. If the vehicle has an
uncharged battery or a battery with
low voltage, try charging or jump
starting the battery. See Jump
Starting - North America 0 235 .
If charging or jump starting the
battery does not work, locate the
hole below the ignition lock. Insert a
flat bladed tool or another key from
the key chain into the opening.
When the lever can be felt, actuate
the lever toward the driver, and
remove the key from the ignition. Starting the Engine Move the shift lever to P (Park) or
N (Neutral). To restart the vehicle
when it is already moving, use
N (Neutral) only.
CautionDo not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
CautionIf you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.

148 Driving and Operating CautionIf the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
while starting the vehicle, damage
may occur to the hydraulic power
steering system and there may be
loss of power steering assist.
Starting Procedure
1. With your foot off the
accelerator pedal, turn the
ignition key to START. When
the engine starts, let go of the
key. The idle speed will go
down as the engine warms. Do
not race the engine
immediately after starting it.
Operate the engine and
transmission gently to allow the
oil to warm up and lubricate all
moving parts. CautionCranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start
after five to 10 seconds,
especially in very cold weather
(below − 18 °C or 0 °F), it could
be flooded with too much
gasoline. Push the accelerator
pedal all the way to the floor
and hold it there as you hold
the key in START for a
maximum of 15 seconds. Wait
at least 15 seconds between
each try, to allow the cranking
motor to cool. When the engine
starts, let go of the key and accelerator. If the vehicle starts
briefly but then stops again,
repeat the procedure. This
clears the extra gasoline from
the engine. Do not race the
engine immediately after
starting it. Operate the engine
and transmission gently until
the oil warms up and lubricates
all moving parts.
Retained Accessory
Power (RAP) The following vehicle accessories
may be used for up to 10 minutes
after the engine is turned off:
.
Power windows
.
Accessory power outlets
Power to the infotainment system
will continue to operate for
30 minutes or until the key is
removed from the ignition switch,
regardless of whether any door will
be opened.

Shifting Into Park To shift into P (Park):
1. Hold the brake pedal down and
set the parking brake.
See Electric Parking Brake
0 155 .
2. Hold the button on the shift
lever and push the lever toward
the front of the vehicle into
P (Park).
3. Turn the ignition to LOCK/OFF.
4. Remove the key.
Leaving the Vehicle with the
Engine Running
{ Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
(Continued) Warning (Continued) Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park 0 149 .
If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking
brake set.
Release the button and check that
the shift lever cannot be moved out
of P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not done properly; then it is difficult to
shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see “ Shifting Into Park ”
previously in this section.
If torque lock does occur, the
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).
Shifting out of Park Automatic Transmission
Shift Lock The vehicle has an automatic
transmission shift lock control
system. The shift lock control
system is designed to:
.
Prevent ignition key removal
unless the shift lever is in
P (Park).
.
Prevent movement of the shift
lever out of P (Park), unless the
ignition is on and the brake
pedal is applied.
