2010 GMC TERRAIN mileage

Instruments and Controls 4-13
Speedometer
The vehicle's speed can be selected
to display on the Driver Information
Center (DIC) and the speedometer
in either kilometers per hour (km/h)
or miles per hour (mph). Telltales on
the speedometer indicate whether
kilometers or miles were chosen.
The DIC will show the vehicles
speed after the limit on the
speedometer has been reached.
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper-resistant
odometer. If the vehicle needs a
new odometer installed, the new
one is set to the mileage of the old
odometer. If this is not possible, it is
set at zero and a label is put on the
driver's door to show the old
mileage reading.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Notice:If the engine is operated
with the tachometer in the shaded
warning area, the vehicle could
be damaged, and the damages
would not be covered by the
vehicle warranty. Do not operate
the engine with the tachometer in
the shaded warning area.
Fuel Gauge
United StatesCanada
When the ignition is on, the fuel
gauge shows about how much fuel
the vehicle has left in the fuel tank. An arrow on the fuel gauge
indicates the side of the vehicle
the fuel door is on.
The gauge will first indicate empty
before the vehicle is out of fuel and
the low fuel light comes on, but the
vehicle's fuel tank should be
filled soon.
Here are some situations that can
occur with the fuel gauge. None of
these indicate a problem with the
fuel gauge.
.At the service station, the fuel
pump shuts off before the gauge
reads full.
.It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.

9-4 Vehicle Care
Vehicle Checks
Doing Your Own
Service Work
{WARNING
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
.Be sure you have sufficient
knowledge, experience,
the proper replacement
parts, and tools before
attempting any vehicle
maintenance task.(Continued)
WARNING (Continued)
.Be sure to use the proper
nuts, bolts, and other
fasteners. English and metric
fasteners can be easily
confused. If the wrong
fasteners are used, parts can
later break or fall off. You
could be hurt. If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see
Service
Publications Ordering Information
on
page 12‑12.
This vehicle has an airbag system.
Before attempting to do your own
service work, see Airbag System
Check on page 2‑40.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
Maintenance Records
on
page 10‑10.

9-12 Vehicle Care
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A“Change Engine Oil
Soon” message comes on.
See Engine Oil Messages
on
page 4‑31. Change the oil as soon as possible within the next 1 000 km
(600 miles). It is possible that,
if driving under the best conditions,
the oil life system might not indicate
that an oil change is necessary for
over a year. However, the engine oil
and filter must be changed at least
once a year and at this time the
system must be reset. Your dealer/
retailer has trained service people
who will perform this work using
genuine parts and reset the system.
It is also important to check the oil
regularly and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
If the vehicle has Driver Information
Center (DIC) buttons:
1. Turn the ignition to ON/RUN, with the engine off.
2. Press the DIC menu button until “Remaining Oil Life” displays.
3. Press and hold the set/clear button until “100%”is displayed.
4. Turn the key to LOCK/OFF.
The system is reset when the
“Change Engine Oil Soon” message
goes off.

Transportation Options
Warranty service can generally be
completed while you wait. However,
if you are unable to wait, GM helps
to minimize your inconvenience by
providing several transportation
options. Depending on the
circumstances, your dealer can
offer you one of the following:
Shuttle Service
Shuttle service is the preferred
means of offering Courtesy
Transportation. Dealers may provide
you with shuttle service to get you
to your destination with minimal
interruption of your daily schedule.
This includes one‐way or round trip
shuttle service within reasonable
time and distance parameters of the
dealer's area.
Public Transportation or Fuel
Reimbursement
If your vehicle requires overnight
warranty repairs, and public
transportation is used instead of the
dealer's shuttle service, the expensemust be supported by original
receipts and can only be up to the
maximum amount allowed by GM
for shuttle service. In addition, for
U.S. customers, should you arrange
transportation through a friend or
relative, limited reimbursement for
reasonable fuel expenses may be
available. Claim amounts should
reflect actual costs and be
supported by original receipts. See
your dealer for information regarding
the allowance amounts for
reimbursement of fuel or other
transportation costs.
Courtesy Rental Vehicle
Your dealer may arrange to provide
you with a courtesy rental vehicle or
reimburse you for a rental vehicle
that you obtain if your vehicle is
kept for an overnight warranty
repair. Rental reimbursement will be
limited and must be supported by
original receipts. This requires that
you sign and complete a rental
agreement and meet state/
provincial, local, and rental vehicle
provider requirements.Requirements vary and may include
minimum age requirements,
insurance coverage, credit card, etc.
You are responsible for fuel usage
charges and may also be
responsible for taxes, levies, usage
fees, excessive mileage, or rental
usage beyond the completion of the
repair.
It may not be possible to provide a
like-vehicle as a courtesy rental.
Additional Program
Information
All program options, such as shuttle
service, may not be available at
every dealer. Please contact your
dealer for specific information
about availability. All Courtesy
Transportation arrangements will be
administered by appropriate dealer
personnel.
