190 Climate Controls Operation Tips
.
Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.
Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.
Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
.
Do not attach any devices to the
air vent slats. This restricts
airflow and may cause damage
to the air vents. Maintenance Passenger Compartment
Air Filter The filter reduces dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
See Maintenance Schedule 0 344 .
See your dealer regarding
replacement of the filter.
Service This vehicle has the new
environmentally friendly refrigerant,
R1234yf. This refrigerant has a
significantly reduced global warming
impact on the environment,
compared to the traditional
automotive refrigerant, R-134a. All
vehicles have a label underhood
that identifies the refrigerant used in
the vehicle.
The refrigerant system should only
be serviced by trained and certified
technicians. The air conditioning
evaporator should never be repaired or replaced by one from a salvage
vehicle. It should only be replaced
by a new evaporator to ensure
proper and safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.

194 Driving and Operating
Steering Variable Effort Steering The vehicle has a steering system
that varies the amount of effort
required to steer the vehicle in
relation to the speed of the vehicle.
The amount of steering effort
required is less at slower speeds to
make the vehicle more
maneuverable and easier to park. At
faster speeds, the steering effort
increases to provide a sport-like feel
to the steering. This provides
maximum control and stability.
Electric Power Steering The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance
is not required.
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort. See your dealer if
there is a problem. If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If steering assist is used for an
extended period of time, power
assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See specific vehicle steering
messages under Vehicle
Messages 0 146 .
See your dealer if there is a
problem.
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

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-9235592) -

Driving and Operating 195The 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. .
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.

Driving and Operating 197.
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 0 217 . .
Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes
should be applied sooner than
when on dry pavement. See
Antilock Brake System
(ABS) 0 214 .
See Driver Mode Control 0 219
.
Allow greater following distance
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.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside Service.
See Roadside Service 0 364 . To get
help and keep everyone in the
vehicle safe: .
Turn on the hazard warning
flashers.
.
Tie a red cloth to an outside
mirror.
{ WarningSnow 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 snow:
.
Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
.
Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
.
Fully open the air outlets on
or under the instrument
panel.

Driving and Operating 205CautionCranking 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. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you press ENGINE START/
STOP. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts,
release the accelerator. If the
vehicle starts briefly but then
stops again, do the same thing.
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.
Stop/Start System
{ WarningExiting the vehicle without first
shifting into P (Park) may cause
the vehicle to move. You or others
may be injured. Because the
vehicle has the auto engine stop/
start feature, the vehicle's engine
might seem to be shut off;
however, once the brake pedal is
released, the engine will start up
again.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before
exiting the vehicle.
The vehicle has a fuel saving stop/
start system to shut off the engine
and help conserve fuel. Auto Engine Stop/Start

208 Driving and Operating Leaving the Vehicle with the
Engine Running
{ WarningIt 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.
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 0 207 .
If you are towing a trailer, see
Driving Characteristics and
Towing Tips 0 255 . If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking brake
set. After shifting into P (Park), try to
move the shift lever out without first
pushing the button on the shift lever.
If you can, the shift lever was not
fully locked into 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 and 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"
listed previously.
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 This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to
prevent movement of the shift lever
out of P (Park), unless the ignition is
in ON/RUN and the brake pedal is
applied.
The shift 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 0 327 for more information.
To shift out of P (Park):
1. Apply the brake pedal.
2. Release the parking brake.
See Electric Parking
Brake 0 214 .
