applied sooner than when on
dry pavement. See Antilock
Brake System (ABS)0287.
.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.
.Select All-Wheel Drive (AWD)
Mode for vehicles equipped
with AWD. Select Snow/Ice
Mode for FWD only vehicles.
See Driver Mode Control
0293 and
All-Wheel Drive 0287.
Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
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 Assistance. See
Roadside Assistance Program
0
489. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine
exhaust under the vehicle.
This may cause exhaust
gases to get inside. Engine
exhaust contains carbon
monoxide (CO), which cannot
(Continued)
Warning (Continued)
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.
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the
highest setting. See
“Climate Control Systems.”
For more information about
CO, see Engine Exhaust

Driving and Operating 261
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the
engine off and partially close
the window. Moving about to
keep warm also helps.
If it takes time for help to
arrive, when running the
engine, push the accelerator
pedal slightly so the engine
runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
The Traction Control System
(TCS) can often help to free a
stuck vehicle. See Traction
Control/Electronic Stability
Control0291. If TCS cannot free the vehicle,
turn TCS off and use the
rocking method. See
“Rocking
the Vehicle to Get it Out”
following.
{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).
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
Transporting a Disabled
Vehicle
0455.
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

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
262 Driving and Operating
much weight it may
properly carry: the Tire and
Loading Information label
and the Certification 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
performance, damage the
tires, and shorten the life
of the vehicle. Tire and Loading
Information Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's
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 tire size of the
original equipment tires (3)
and the recommended cold
tire inflation pressures (4).
For more information on
tires and inflation see Tires
0
418 and
Tire Pressure 0427.
There is also important
loading information on the
Certification 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 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 ofavailable 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 your
vehicle. Consult this
manual to determine
how this reduces the
available cargo and
luggage load capacity of
your vehicle.”
See Trailer Towing (LSY

Starting and
Operating
New Vehicle Break-In
Caution
Follow these recommended
guidelines during the first
2 414 km (1,500 mi) of driving
this vehicle. Parts have a
break-in period and
performance will be better in
the long run.
.Avoid full throttle starts
and abrupt stops. (Continued)
Caution (Continued)
.Do not exceed 4000
engine rpm.
.Avoid driving at any one
constant speed, fast
or slow.
.Do not drive above
129 km/h (80 mph).
.Avoid downshifting to
brake or slow the vehicle
when the engine speed
will exceed 4000 rpm.
.Do not let the engine
labor. Never lug the engine
in high gear at low speeds.
With a manual
transmission, shift to the
next lower gear. This rule
applies at all times, not
just during the break-in
period.
.Do not participate in
racing events, sport
driving schools, or similar
activities during this
break-in period.

266 Driving and Operating
Caution (Continued)
.Check engine oil with
every refueling and add if
necessary. Oil and fuel
consumption may be
higher than normal during
the first
2 414 km (1,500 mi).
.To break in new tires,
drive at moderate speeds
and avoid hard cornering
for the first
322 km (200 mi). New tires
do not have maximum
traction and may tend
to slip.
.New brake linings also
need a break-in period.
Avoid making hard stops
during the first
322 km (200 mi). This is
recommended every time
brake linings are replaced.
.Should the vehicle be used
for racing or competitive
driving (after break-in), the
rear axle lubricant must be
replaced beforehand.See Track Events and
Competitive Driving (V-Series
and V-Series Blackwing)
0246.
On new vehicles, the various
mechanical and electrical
systems experience a
“break-in” period during the
first 6,400 km (4,000 miles) of
routine driving. As the vehicle
is driven, the mechanical
systems adjust to provide
optimal fuel economy and
transmission shift
performance.
Electrical systems will adapt
and calibrate during the
break-in period. A one-time
occurrence of clicks and
similar vehicle noises is normal
during this process.
Normal driving charges the
vehicle’s battery to achieve
the best operation of the
vehicle, including fuel
economy.
Composite Materials
This vehicle may be equipped
with parts containing carbon
fiber, sheet-molding
compound, or other composite
materials. Dealer-installed
accessories may also contain
composite materials.
{Warning
Exposed edges of parts
containing carbon fiber and
other composite materials
can be sharp. Contact with
these parts could result in
injury. Use caution to avoid
contacting these parts,
including when washing the
vehicle. If the parts are
damaged, replace the parts
promptly with replacements
from your dealer.
