190 Driving and Operating
{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 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 0206.
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. If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See
Traction
Control/Electronic Stability Control
0 222.
{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

GMC Terrain/Terrain Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-12146071) - 2019 - crc - 7/27/18
Driving and Operating 191
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,
seeTowing the Vehicle 0363.
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 much weight it may
properly carry, the Tire and
Loading Information label and
the Certification/Tire 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 distance,
damage the tires, and shorten
the life of the vehicle.Tire and Loading Information
Label
Example Label
A vehicle-specific Tire and
Loading Information label is
attached to the 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
size of the original equipment

196 Driving and Operating
If the vehicle is in R (Reverse), D
(Drive) or L (Low), the vehicle will
shift to P (Park), the ignition will turn
off, and Retained Accessory Power
(RAP) will remain active. See
Retained Accessory Power (RAP)
0202.
If the vehicle is in N (Neutral), the
ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition system will
turn off.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is turned
off and either front door is opened.
A sound may be heard as the lock
actuates or releases. The steering
column lock may not release with
the wheels turned off center. If this
happens, the vehicle may not start.
Move the steering wheel from left to
right while attempting to start the
vehicle. If this does not work, the
vehicle needs service. 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 turned 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), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop and shift to P (Park).
4. Set the parking brake. See Electric Parking Brake 0219.
Press ENGINE START/STOP
to turn the vehicle off.{Warning
Turning 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,
press and hold ENGINE START/
STOP for longer than two seconds,
or press twice in five seconds.
ACC/ACCESSORY (Amber
Indicator Light) : This mode allows
you to use some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after
five minutes to prevent battery
rundown.

is charged, but the engine still will
not start, the vehicle needs service. If the light does not come on when
the engine is cold, the vehicle
needs service.
If the battery does not have enough
charge to start the engine, see
Battery - North America
0309.
Check that the correct engine oil
has been used and changed at
appropriate intervals. If the wrong oil
is used, the engine may be harder
to start.
Be sure to use the proper fuel for
existing weather conditions. See
Fuel for Diesel Engines 0262.
If the engine starts, runs a short
time, then stops, the vehicle needs
service.
{Warning
Do not use gasoline or starting
aids, such as ether, in the air
intake. They could damage the
engine, which may not be
covered by the vehicle warranty. (Continued)
Warning (Continued)
They could also cause a fire,
which could cause serious
personal injury.
Stop/Start System
If equipped, the Stop/Start system
will shut off the engine to help
conserve fuel. It has components
designed for the increased number
of starts.
{Warning
The automatic engine Stop/Start
feature causes the engine to shut
off while the vehicle is still on. Do
not exit the vehicle before shifting
to P (Park). The vehicle may
restart and move unexpectedly.
Always shift to P (Park), and then
turn the ignition off before exiting
the vehicle.

Diesel Particulate
Filter
The Diesel Particulate Filter (DPF)
system filters soot particles out of
the exhaust gases. The DPF is
under the vehicle in the exhaust
system.
Depending on a number of factors
monitored by the engine computer,
the DPF will need to be cleaned of
accumulated solids. When a
cleaning is needed, the engine
computer will initiate a self-cleaning
function that runs automatically
during driving without any
notification. The filter is cleaned by
periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and
may take up to 25 minutes. Fuel
consumption may be higher during
this period.
While the DPF cleaning is
automatically controlled by the
engine computer, the vehicle will
need to operate continuously for
approximately 25 minutes and atspeeds greater than 50 km/h
(30 mph) to clean the DPF
effectively.
If the vehicle is used for numerous
short trips or extended slow-speed
operation, the engine computer may
not be able to adequately heat up
the exhaust system to clean the
DPF effectively. The engine
computer has been designed to
continuously monitor the condition
of the DPF. When the engine
computer detects that the DPF is
nearly full of particulates and that
the vehicle is not being operated in
a manner that would allow effective
automatic DPF cleaning, a Driver
Information Center (DIC) message
will display. Start the cleaning
process as soon as possible.
Cleaning Process
To activate the cleaning process,
continue driving safely, and keep
vehicle speed above 50 km/h (30
mph) until the warning message in
the DIC turns off.
If the vehicle continues to be driven
with the DPF warning message on,
and the exhaust filter is not cleaned
as required, the malfunction
indicator lamp and the ENGINE
POWER IS REDUCED message
will come on. Dealer service is
necessary.
See
Malfunction Indicator Lamp
(Check Engine Light) 0133.
{Warning
During DPF self cleaning or
during extended idling while
parked, the exhaust system and
exhaust gases are very hot.
Things that burn could touch hot
exhaust parts under the vehicle
and ignite. You or others could be
burned. Do not park, or idle for an
extended period of time, near or
over papers, leaves, dry grass,
or other things that can burn.
Keep the exhaust area clear of
material that could ignite or burn.
See Parking over Things That
Burn 0205 for more information.
