2007 GMC ACADIA towing

Gasoline Octane
Use regular unleaded gasoline with a posted
octane rating of 87 or higher. For best performance
or trailer towing, you could choose to use middle
grade 89 octane unleaded gasoline. If the
octane rating is less than 87, you might notice
an audible knocking noise when you drive,
commonly referred to as spark knock. If this
occurs, use a gasoline rated at 87 octane or higher
as soon as possible. If you are using gasoline
rated at 87 octane or higher and you hear heavy
knocking, the engine needs service.
Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 or 3.511 in Canada. Some
gasolines contain an octane-enhancing additive
called methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend against the
use of gasolines containing MMT. SeeAdditives
on page 389for additional information.
California Fuel
If your vehicle is certied to meet California
Emissions Standards, it is designed to operate
on fuels that meet California specications.
See the underhood emission control label.
If this fuel is not available in states adopting
California emissions standards, your vehicle will
operate satisfactorily on fuels meeting federal
specications, but emission control system
performance might be affected. The malfunction
indicator lamp could turn on and your vehicle might
fail a smog-check test. SeeMalfunction Indicator
Lamp on page 226. If this occurs, return to
your authorized dealer/retailer for diagnosis.
If it is determined that the condition is caused
by the type of fuel used, repairs might not
be covered by your warranty.

If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not
come back on, you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. If you still
have the warning, turn off the engine and
get everyone out of the vehicle until it cools down.
Also, see “Overheated Engine Protection
Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
This emergency operating mode lets your vehicle
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an
overheat protection mode which alternates ring
groups of cylinders helps prevent engine damage.
In this mode, there is a signicant loss in power and
engine performance. The temperature gage
indicates an overheat condition exists. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life
system. SeeEngine Oil on page 397.

(g)A fluid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the fluid level checked. Add fluid
if needed.
(h)Change automatic transmission fluid if the
vehicle is mainly driven under one or more
of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F
(32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or
delivery service.
(i)Drain, flush, and refill cooling system.
This service can be complex; you should have
your dealer/retailer perform this service. See
Engine Coolant on page 406 for what to use.
Inspect hoses. Clean radiator, condenser, pressure
cap, and filler neck. Pressure test the cooling
system and pressure cap.(j)Check system for interference or binding and
for damaged or missing parts. Replace parts
as needed. Replace any components that have
high effort or excessive wear. Do not lubricate
accelerator or cruise control cables.
(k)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
(l)If you drive regularly under dusty conditions,
inspect the filter at each engine oil change.
Owner Checks and Services
These owner checks and services should be
performed at the intervals specied to help ensure
the safety, dependability, and emission control
performance of your vehicle. Your dealer/retailer
can assist you with these checks and services.
Be sure any necessary repairs are completed
at once. Whenever any uids or lubricants are
added to your vehicle, make sure they are
the proper ones, as shown inRecommended
Fluids and Lubricants on page 511.

If your vehicle cannot be driven, know where
the towing service will be taking it. Get a
card from the tow truck operator or write down
the driver’s name, the service’s name, and
the phone number.
Remove any valuables from your vehicle before
it is towed away. Make sure this includes your
insurance information and registration if you
keep these items in your vehicle.
Gather the important information you will need
from the other driver. Things like name,
address, phone number, driver’s license
number, vehicle license plate, vehicle make,
model and model year, Vehicle Identication
Number (VIN), insurance company and policy
number, and a general description of the
damage to the other vehicle.
If possible, call your insurance company from
the scene of the accident. They will walk you
through the information they will need. If they
ask for a police report, phone or go to the police
department headquarters the next day and you
can get a copy of the report for a nominal fee. In
some states/provinces with “no fault” insurance
laws, a report may not be necessary. This is
especially true if there are no injuries and both
vehicles are driveable.
Choose a reputable collision repair facility for
your vehicle. Whether you select a dealer/
retailer or a private collision repair facility to x
the damage, make sure you are comfortable
with them. Remember, you will have to feel
comfortable with their work for a long time.
Once you have an estimate, read it carefully
and make sure you understand what work will
be performed on your vehicle. If you have a
question, ask for an explanation. Reputable
shops welcome this opportunity.
