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 of available 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, the 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 on page 9‑61
for important information on
towing a trailer, towing safety
rules and trailering tips.Example 1
A.
Vehicle Capacity Weight
for Example 1 = 453 kg
(1,000 lbs).
B.Subtract Occupant Weight
@ 68 kg (150 lbs) × 2 =
136 kg (300 lbs).
C.Available Occupant and
Cargo Weight = 317 kg
(700 lbs).

C.Available Cargo Weight =
113 kg (250 lbs).
Example 3
A.
Vehicle Capacity Weight
for Example 3 = 453 kg

B.Subtract Occupant Weight
@ 91 kg (200 lbs) × 5 =
453 kg (1,000 lbs).
C.Available Cargo Weight =
0 kg (0 lbs).
Refer to the vehicle's Tire and
Loading Information label for
specific information about the vehicle's capacity weight and
seating positions. The combined
weight of the driver, passengers,
and cargo should never exceed
the vehicle's capacity weight.
Certification Label
Label Example
A vehicle-specific Certification
label is attached to the lower
center pillar on the driver
side of the vehicle or on the
rear edge of the driver door.
Page 251 of 426

Black plate (25,1)GMC Terrain Owner Manual - 2011
Driving and Operating 9-25
The label shows the size of the
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. This is called
Gross Vehicle Weight Rating
(GVWR). The GVWR includes
the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label also
tells you the maximum weights
for the front and rear axles,
called Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear
axles, you need to go to a weigh
station and weigh the vehicle.
Your dealer can help you with
this. Be sure to spread out the
load equally on both sides of the
center line.Never exceed the GVWR for the
vehicle, or the GAWR for either
the front or rear axle.
If the vehicle is carrying a heavy
load, it should be spread out.
See
“Steps for Determining
Correct Load Limit” earlier in this
section.
{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
shorten the life of the vehicle. Your warranty does not cover
parts or components that fail
because of overloading.
The label will help you decide
how much cargo and installed
equipment your vehicle can
carry.
Using heavier suspension
components to get added
durability might not change your
weight ratings. Ask your dealer
to help you load your vehicle the
right way.

9-26 Driving and Operating
If you put things inside
your vehicle–like suitcases,
tools, packages, or anything
else –they will go as fast as the
vehicle goes. If you have to stop
or turn quickly, or if there is a
crash, they will keep going.
{WARNING
Things inside the vehicle can
strike and injure people in a
sudden stop or turn, or in a
crash.
.Put things in the cargo
area of the vehicle. In the
cargo area, put them as
far forward as possible.
Try to spread the weight
evenly.
(Continued)
WARNING (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
Notice: The 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.
.During the first 1 000 km
(600 mi), avoid using more
than moderate acceleration
in lower gears and avoid
vehicle speeds above
110 km/h (68 mph).
.Between the first 1 000 km
(600 mi) and 5 000 km
(3,000 mi), heavy
acceleration in lower
gears can be used.
Page 253 of 426

Black plate (27,1)GMC Terrain Owner Manual - 2011
Driving and Operating 9-27
Vehicle speeds above
110 km/h (68 mph) should
be limited to five minutes
per use.
.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
breaking-in guideline every
time you get new brake
linings.
.Do not tow a trailer during
break-in. SeeDriving
Characteristics and Towing
Tips on page 9‑58 for the
trailer towing capabilities
of your vehicle and more
information.
Following break‐in, engine speed
and load can be gradually
increased.
Ignition Positions
The ignition switch has four different
positions.
Notice: Using 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 to ON/RUN and apply the
brake pedal.
A (STOPPING THE ENGINE/
LOCK/OFF):
When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9‑30.
This is the only position from which
the key can be removed. This locks
the steering wheel, 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.
Page 254 of 426

Black plate (28,1)GMC Terrain Owner Manual - 2011
9-28 Driving and Operating
In an emergency, if the vehicle must
be shut off while driving:
1. Brake using a firm and steadypressure. 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, shift to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9‑38.{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.
5. If the vehicle must be shut off while driving, turn the ignition to
ACC/ACCESSORY.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from
right to left while turning the key
to ACC/ACCESSORY. If this does
not work, then the vehicle needs
service.
B (ACC/ACCESSORY): This
position provides power to some
of the electrical accessories.
It unlocks the steering wheel and
ignition. To move the key from ACC/ACCESSORY to LOCK/OFF,
push in the key and then turn it to
LOCK/OFF.
C (ON/RUN):
The ignition switch
stays in this position when the
engine is running. This position
can be used to operate the
electrical accessories, including the
ventilation fan and 12‐volt power
outlets, as well as to display some
warning and indicator lights. The
transmission is also unlocked in this
position on automatic transmission
vehicles.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not start if the
battery is allowed to drain for an
extended period of time.
D (START): This position starts
the engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
Page 255 of 426

Black plate (29,1)GMC Terrain Owner Manual - 2011
Driving and Operating 9-29
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.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
vehicle when it is already moving,
use N (Neutral) only.
Notice: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.
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.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key
is turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking
for a few seconds or until the
vehicle starts. If the engine does
not start and the key is held
in START for many seconds,
cranking will be stopped after
15 seconds to prevent cranking
motor damage. To prevent
gear damage, this system also
prevents cranking if the engine
is already running. Engine
cranking can be stopped by
turning the ignition switch
to ACC/ACCESSORY or
LOCK/OFF.Notice:
Cranking the engine for
long periods of time, by returning
the key 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
5 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.

9-30 Driving and Operating
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.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.
Retained Accessory
Power (RAP)
These vehicle accessories can be
used for up to 10 minutes after the
engine is turned off:
.Audio System
.Power Windows
.Sunroof (if equipped) Power to the audio system will
continue to operate for up to
10 minutes or until the driver door
is opened.
Power to the power windows and
sunroof will continue to operate for
up to 10 minutes or until any door is
opened.
All these features will work when
the key is in ON/RUN or ACC/
ACCESSORY.
Engine Coolant Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below
−18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above −18°C (0°F).
To Use The Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is located on
the passenger side of the engine
compartment, in front of the air
cleaner.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a fire. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
