2007 GMC ACADIA check engine light

AUTOMATIC LIGHT CONTROL ON
This message displays when the automatic
headlamps are turned on. This message clears
itself after 10 seconds.
BATTERY SAVER ACTIVE
This message displays when the system detects
that the battery voltage is dropping below expected
levels. The battery saver system starts reducing
certain features of the vehicle that you may be able
to notice. At the point that the features are disabled,
this message is displayed. It means that the vehicle
is trying to save the charge in the battery.
Turn off all unnecessary accessories to allow
the battery to recharge.
The normal battery voltage range is
11.5 to 15.5 volts.
CHANGE ENGINE OIL SOON
This message displays when the engine oil needs
to be changed. When you change the engine oil, be
sure to reset the CHANGE ENGINE OIL SOON
message. SeeEngine Oil Life System on page 400
for information on how to reset the message.
SeeEngine Oil on page 397andScheduled
Maintenance on page 502for more information.
CHECK TIRE PRESSURE
This message displays when the pressure in
one or more of the vehicle’s tires need to
be checked. This message also displays LEFT
FRONT, RIGHT FRONT, LEFT REAR, or
RIGHT REAR to indicate which tire needs to be
checked. You can receive more than one tire
pressure message at a time. To read the other
messages that may have been sent at the
same time, press the set/reset button or the trip
odometer reset stem. If a tire pressure message
appears on the DIC, stop as soon as you can.
Have the tire pressures checked and set to those
shown on the Tire Loading Information label.
SeeTires on page 435,Loading Your Vehicle
on page 361, andInflation - Tire Pressure
on page 442. The DIC display also shows the
tire pressure values for the front and rear tires by
pressing the vehicle information button. See
“DIC Operation and Displays (With DIC Buttons)”
earlier in this section. If the tire pressure is
low, the low tire pressure warning light comes on.
SeeTire Pressure Light on page 225.

SERVICE TRANSMISSION
This message displays when there is a problem
with the transmission. See your dealer/retailer
for service.
SERVICE VEHICLE SOON
This message displays when a non-emissions
related malfunction occurs. Have the vehicle
serviced by your dealer/retailer as soon as
possible.
SPEED LIMITED TO XXX MPH (KM/H)
This message displays when your vehicle speed
is limited to 80 mph (128 km/h) because the
vehicle detects a problem in the speed variable
assist steering system. Have your vehicle serviced
by your dealer/retailer.
STARTING DISABLED SERVICE
THROTTLE
This message displays when your vehicle’s throttle
system is not functioning properly. Have your
vehicle serviced by your dealer/retailer.
THEFT ATTEMPTED
This message displays if the content theft-deterrent
system has detected a break-in attempt while
you were away from your vehicle. SeeContent
Theft-Deterrent on page 118for more information.
TIGHTEN GAS CAP
This message may display along with the check
engine light on the instrument panel cluster if
the vehicle’s fuel cap is not tightened properly.
SeeMalfunction Indicator Lamp on page 226.
Reinstall the fuel cap fully. SeeFilling the Tank
on page 390. The diagnostic system can determine
if the fuel cap has been left off or improperly
installed. A loose or missing fuel cap allows fuel
to evaporate into the atmosphere. A few driving
trips with the cap properly installed should turn
this light and message off.

But you will use it when you brake. Once the
power assist is used up, it can take longer to stop
and the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. SeeAccessories
and Modifications on page 385.
Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System
(ABS), an advanced electronic braking system that
will help prevent a braking skid.
When you start the engine and begin to drive
away, ABS will check itself. You might hear
a momentary motor or clicking noise while this test
is going on, and you might even notice that the
brake pedal moves a little. This is normal.
If there is a problem
with ABS, this warning
light will stay on.
SeeAnti-Lock Brake
System Warning
Light on page 223.Let us say the road is wet and you are driving
safely. Suddenly, an animal jumps out in front of
you. You slam on the brakes and continue braking.
Here is what happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the
computer will separately work the brakes at each
wheel.
335

You can run the engine to keep warm, but be
careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see
it or smell it, so you might not know it is
in your vehicle. Clear away snow from
around the base of your vehicle, especially
any that is blocking the exhaust pipe.
And check around again from time to time
to be sure snow does not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.
Run the engine only as long as you must.
This saves fuel. When you run the engine, make it
go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat
that you get and it keeps the battery charged.

How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission uid to use. See
Recommended Fluids and Lubricants on page 511.
If the uid level is low, add only enough of the
proper uid to bring the level into the crosshatched
area on the dipstick.
1. Remove the dipstick.
2. Using a long-neck funnel, add enough uid at
the dipstick hole to bring it to the proper level.
It does not take much uid, generally
less than one half of a pint (0.25 L).
Do not overll.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 511.
3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
4. When the correct uid level is obtained,
twist & lock dipstick cap in place.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating or if you need
to add coolant to the radiator, seeEngine
Overheating on page 410.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to
−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
