2010 GMC TERRAIN window

Driving and Operating 8-41
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade. This feature is designed to
prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. After driver
completely stops and holds the
vehicle in a complete standstill on a
grade, HSA will be automatically
activated. During the transition
period between when the driver
releases the brake pedal and starts
to accelerate to drive off on a grade,
HSA holds the braking pressure to
ensure that there is no rolling back.
The brakes will automatically
release when the accelerator pedal
is applied within the two second
window. It will not activate if the
vehicle is in a drive gear and facing
downhill or if the vehicle is facing
uphill and in R (Reverse).
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
On a front-wheel-drive vehicle, the
system operates if it senses that
one or both of the front wheels are
spinning or beginning to lose
traction. On an All-Wheel-Drive
(AWD) vehicle, the system will
operate if it senses that any of the
wheels are spinning or beginning to
lose traction. When this happens,
the system brakes the spinning
wheel(s) and/or reduces engine
power to limit wheel spin.
The system may be heard or felt
while it is working, but this is
normal.The TCS/StabiliTrak warning light
will flash to indicate that the traction
control system is active.
This warning light comes on if there
is a problem with TCS, and the
system will not limit wheel spin.
Adjust your driving accordingly.
TCS automatically comes on
whenever the vehicle is started.
To limit wheel spin, especially in
slippery road conditions, the system
should always be left on. But, TCS
can be turned off if needed.
Notice:Do not repeatedly brake
or accelerate heavily when TCS is
off. The vehicle's driveline could
be damaged.

9-20 Vehicle Care
Engine Overheating
The vehicle has an indicator to warn
of engine overheating. There is an
engine coolant temperature warning
light on the vehicle's instrument
panel. SeeEngine Coolant
Temperature Gauge on page 4‑14.
The decision may be made not
to lift the hood when this warning
appears, but instead get service
help right away. See Roadside
Assistance Program on page 12‑6.
If the decision to lift the hood is
made, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice: Engine damage from
running the engine without
coolant is not covered by the
warranty.
If Steam Is Coming From The
Engine Compartment
{WARNING
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when your
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop your
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest
fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped.
If it is safe to do so, pull off
the road, shift to P (Park) or
N (Neutral) and let the
engine idle.

Fuse Block
To remove the fuse block cover,
squeeze the clips on the cover and
lift it straight up.
The vehicle may not be equipped
with all of the fuses and relays
shown.
Notice:Spilling liquid on any
electrical components on the
vehicle may damage it. Always
keep the covers on any electrical
component.

Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in psi (pounds per
square inch) or kPa (kilopascal).
Accessory Weight
:This
means the combined weight
of optional accessories.
Some examples of optional
accessories are, automatic
transmission, power steering,
power brakes, power windows,
power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width. Belt
:A rubber coated layer of
cords that is located between
the plies and the tread. Cords
may be made from steel or other
reinforcing materials.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire
:A pneumatic tire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure
:The
amount of air pressure in a tire,
measured in psi (pounds per
square inch) or kPa (kilopascal)
before a tire has built up heat
from driving. See Tire Pressure
on page 9‑52. Curb Weight
:The weight of a
motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil,
and coolant, but without
passengers and cargo.
DOT Markings
:A code molded
into the sidewall of a tire
signifying that the tire is in
compliance with the U.S.
Department of Transportation
(DOT) motor vehicle safety
standards. The DOT code
includes the Tire Identification
Number (TIN), an alphanumeric
designator which can also
identify the tire manufacturer,
production plant, brand, and
date of production.
GVWR
:Gross Vehicle Weight
Rating. See Vehicle Load Limits
on page 8‑22.

Vehicle Care 9-89
At least every spring, flush these
materials from the underbody with
plain water. Clean any areas where
mud and debris can collect. Dirt
packed in close areas of the frame
should be loosened before being
flushed. Your dealer/retailer or an
underbody car washing system can
do this.
Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical
fallout. Airborne pollutants can fall
upon and attack painted surfaces on
the vehicle. This damage can take
two forms: blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.
Interior Care
The vehicle's interior will continue to
look its best if it is cleaned often.
Dust and dirt can accumulate on the
upholstery and cause damage to
the carpet, fabric, leather, and
plastic surfaces. Stains should be
removed quickly as extreme heat
could cause them to set rapidly.
Lighter colored interiors may require
more frequent cleaning.
Newspapers and garments that can
transfer color to home furnishings
can also transfer color to the
vehicle's interior.
Remove dust from small buttons
and knobs with a small brush with
soft bristles.
Your dealer/retailer has products for
cleaning the vehicle's interior. When
cleaning the vehicle's interior, only
use cleaners specifically designed
for the surfaces that are beingcleaned. Permanent damage can
result from using cleaners on
surfaces for which they were not
intended. Apply the cleaner directly
to the cleaning cloth to prevent
over-spray. Remove any accidental
over-spray from other surfaces
immediately.
Notice:
Using abrasive cleaners
when cleaning glass surfaces on
the vehicle, could scratch the
glass and/or cause damage to the
rear window defogger. When
cleaning the glass on the vehicle,
use only a soft cloth and glass
cleaner.
Cleaners can contain solvents that
can become concentrated in the
vehicle's interior. Before using
cleaners, read and adhere to all
safety instructions on the label.
While cleaning the vehicle's interior,
maintain adequate ventilation by
opening the vehicle's doors and
windows.
