{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. ON/RUN/START (Green Indicator
Light) :
This mode is for starting
and driving. With the ignition off and
the brake pedal applied, pressing
the button once will turn the ignition
on. Once engine cranking begins,
release the button. Engine cranking
will continue until the engine starts.
See Starting the Engine 0181. The
ignition will then remain in on.
Service Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off and
the brake pedal not applied,
pressing and holding ENGINE
START/STOP for more than
five seconds will place the vehicle in
Service Mode. The instruments and
audio systems will operate as they
do in ON/RUN, but the vehicle will
not be able to be driven. The engine
will not start in Service Mode. Press
ENGINE START/STOP again to turn
the vehicle off.
Starting the Engine
Shift the vehicle into P (Park) or
N (Neutral). To restart the engine
when the vehicle is already moving,
use N (Neutral) only.
Caution
Do 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.
Caution
If 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.
See Add-On Electrical Equipment
0 271.

Mexico-13556230) - 2020 - CRC - 9/4/19
182 Driving and Operating
Gasoline Engine Starting
Procedure1. With the Keyless Access system, the Remote Keyless
Entry (RKE) transmitter must
be in the vehicle. Press
ENGINE START/STOP with the
brake pedal applied. When the
engine begins cranking, let go
of the button.
The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it.
If the RKE transmitter is not in
the vehicle, if there is
interference, or if the RKE
battery is low, a Driver
Information Center (DIC) will
display a message. See
Remote Keyless Entry (RKE)
System Operation 08.Caution
Cranking the engine for long
periods of time, by trying to start
the engine 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.
Diesel Engine Starting Procedure
The diesel engine starts differently
than a gasoline engine. 1. With the Keyless Access system, the RKE transmitter
must be in the vehicle. Press
ENGINE START/STOP with the
brake pedal applied to start. If it
is too cold, the wait-to-start
light will come on and there will
be a short delay before
starting. See Wait-to-Start Light
0 121. This light may not come
on if the engine is warm.
The engine has a fast warm-up
glow plug system. The
wait-to-start light will illuminate
for a much shorter time than
most diesel engines, due to the
rapid heating of the glow plug
system.

Driving and Operating 183
Caution
If the wait-to-start light stays on
after starting the vehicle, the
vehicle may not run properly.
Have the vehicle serviced
right away.
2. If the engine does not start after 15 seconds of cranking,
wait one minute for the
cranking motor to cool, then try
the same steps again.
If you are trying to start the engine
after the vehicle has run out of fuel,
follow the steps in Running Out of
Fuel (Diesel) 0256.
When the engine is cold, let it run
for a few minutes before driving.
This lets oil pressure build up. The
engine will sound louder when it
is cold.
Cold Weather Starting (Diesel
Engine)
Use the recommended engine oil
when the outside temperature drops
below freezing. See Engine Oil
0 283. When the outside
temperature drops below –18°C
(0°F), use of the engine heater is
recommended.
See Fuel for Diesel Engines 0250
for information on what fuel to use in
cold weather.
If the Diesel Engine Will Not
Start
If the vehicle has run out of fuel, see
Running Out of Fuel (Diesel) 0256.
If the vehicle is not out of fuel, and
the engine will not start:
Press ENGINE START/STOP.
Immediately after the wait-to-start
light goes off, press ENGINE
START/STOP to start the vehicle.
If the light does not go off, wait a
few seconds, then try starting the
engine again. See your dealer for a
starting system check. If the light comes on and then goes
off, and it is known that the battery
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
0298.
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 0250.
If the engine starts, runs a short
time, then stops, the vehicle needs
service.

{Warning
During DPF self-cleaning or
during extended idling in P (Park),
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.
SeeParking over Things That
Burn 0190.
Caution
Avoid extended idling because
the DPF system is not capable of
self-cleaning at idle. During
extended idling, monitor the
instrument cluster lights and DIC
(Continued)
Caution (Continued)
for messages and take
appropriate action. Continued
idling with the warning light/
message on could cause damage
to the DPF requiring repair and
possible replacement that might
not be covered by the vehicle
warranty.
During self-cleaning there will be a
change in the exhaust sound and
engine idle speed. Along with this, a
burning smell and reduction in fuel
economy may be noticed. This is
normal.
If the vehicle is idled or driven on
very short trips with the DPF
warning message on and the
exhaust filter is not cleaned as
required, the malfunction indicator
lamp and a DIC message will
display. See your dealer. Also see
Malfunction Indicator Lamp (Check
Engine Light) 0115. If equipped with Power
Take-Off (PTO), monitor the
instrument cluster for lights related
to the DPF.
See
Accessories and Modifications
0 275 if you are adding accessories
or modifying the vehicle.
Manual Regeneration of Diesel
Particulate Filter
This feature is only available on
Fleet and Commercial vehicles.
To verify that the vehicle has this
feature, refer to the Vehicle Service
Parts Identification label (SPID) for
RPO code FPF or see
www.gmupfitter.com to contact the
GM Upfitter Integration Group.
If equipped, this feature allows for
manual cleaning/regeneration of the
DPF when it is unable to clean
itself. It may be necessary to
perform manual regeneration if
driving conditions —such as
extended slow speed, stop-and-go
traffic, extended idling, short drive
cycles, or stationary PTO operation
— prevent DPF self-cleaning.

In certain cold conditions, it is
possible to find some frozen DEF in
the DEF fill pipe opening. If this
condition prevents the filling of a
DEF tank, place the vehicle in a
warm garage overnight.
For information on how to fill the
DEF tank, seeFilling the Tank
(Gasoline) 0257 or
Filling the Tank (Diesel) 0258.
Exhaust Fluid Low
A full DEF tank will last for several
thousand kilometers (miles),
depending on vehicle usage. As the
exhaust fluid level drops, warnings
will automatically be displayed in the
DIC. Exhaust fluid level status is
available in the DIC. See “Diesel
Exhaust Fluid (DEF) Level (Diesel
Engine Only)” inDriver Information
Center (DIC) (Base and Midlevel)
0 124 or
Driver Information Center (DIC)
(Uplevel) 0130.
To avoid vehicle speed limitations,
the DEF tank should be refilled at
the first opportunity after a low
warning indication. If DEF is added before the EXHAUST FLUID
EMPTY REFILL NOW message
appears, it may take several km/mi
for the DIC message to update.
If the vehicle speed has been
limited and DEF has been added, it
may take up to 30 seconds after
engine start with the vehicle
stopped for the EXHAUST FLUID
EMPTY REFILL NOW message to
clear. If the vehicle is driven prior to
the DIC message clearing, the
vehicle speed will still be limited.
If the DIC message clears while
driving, the speed limitation will be
removed gradually.
If DEF is added under freezing
conditions, additional time may be
required to remove speed limitations
and it may require less fluid to fill
the DEF tank.
The DIC message EXHAUST
FLUID RANGE: XXXX km (mi)
displays at approximately 1 600 km
(1,000 mi) of fluid range remaining.
This message appears again at
approximately 500 km (300 mi) of
remaining range before the exhaust
fluid tank becomes empty.Below 500 km (300 mi) of range
remaining, these messages will
appear every time the vehicle is
started.
Below 121 km (75 mi) of range
remaining, the DIC message
EXHAUST FLUID LOW SPEED
LIMITED SOON displays. This
message will display every time the
vehicle is started.
If these warnings are ignored and
the DEF tank becomes empty, the
DIC message EXHAUST FLUID
EMPTY REFILL NOW - 563 KM
(350 MI) UNTIL 104 KM/H (65 MPH)
MAX SPEED displays. The
displayed mileage will decrease as
driving continues. A warning light

206 Driving and Operating
The system will automatically
command downshifts to reduce
vehicle speed. The normal shift
pattern will return once the vehicle
is on a low grade or when the
accelerator pedal is pressed.
While in the Electronic Range
Select (ERS) mode, grade braking
is deactivated, allowing the driver to
select a range and limiting the
highest gear available. Grade
braking is available for normal
driving and in Tow/Haul Mode.
SeeAutomatic Transmission 0201.Drive Systems
All-Wheel Drive
For information on All-Wheel
Drive (AWD), see Driver Mode
Control 0214.
Brakes
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while
braking hard.
ABS performs a system check when
the vehicle is first driven.
A momentary motor or clicking noise
may be heard while this test is going
on, and the brake pedal may move
slightly. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
0 118.

GMC Terrain/Terrain Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-13556230) - 2020 - CRC - 9/4/19
Driving and Operating 207
ABS does not change the time
needed to get a foot on the brake
pedal and does not always
decrease stopping distance. If you
get too close to the vehicle ahead,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room ahead to stop,
even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly.
Hearing or feeling ABS operate is
normal.
Braking in Emergencies
ABS allows steering and braking at
the same time. In many
emergencies, steering can help
even more than braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a
Yor PARK
Electric Parking Brake light, and a
8
Service Parking Brake light or
Service Parking Brake message. See
Electric Parking Brake Light
0 118 and
Service Electric Parking Brake Light
0 118.
Before leaving the vehicle, check for
the
Yor PARK light to ensure that
the parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK light
flashes continuously, then the EPB
is only partially applied or there is a
problem with the EPB. A Driver
Information Center (DIC) message
will display. Release the EPB and
try to apply it again. If the light does
not come on, or keeps flashing,
have the vehicle serviced. Do not
drive the vehicle if the
Yor PARK
