2007 BUICK LACROSSE oil level

If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will
provide easier cold starting and better protection
for the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you will need for
good performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and lter.
This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change
will be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A change engine oil light or, if
your vehicle has the Driver Information Center
(DIC), a CHANGE OIL SOON message will come
on. SeeChange Engine Oil Light on page 195
orDIC Warnings and Messages on page 208.
Change the oil as soon as possible within the next
600 miles (1 000 km). It is possible that, if you
are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, the engine
oil and lter must be changed at least once a
year and at this time the system must be reset.
Your dealer has GM-trained service people
who will perform this work using genuine GM parts
and reset the system. It is also important to
check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) 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
The Engine Oil Life System calculates when to
change the engine oil and lter based on vehicle
use. Anytime the oil is changed, reset the system
so it can calculate when the next oil change is
required. If a situation occurs where you change the
oil prior to a change engine oil light or CHANGE OIL
SOON message being turned on, reset the system.
After changing the engine oil, reset the system by
performing the following steps:
Vehicles with Driver Information Center (DIC)
1. Press the option button on the DIC until
ENGINE OIL MONITOR appears on the
DIC screen.
2. Press the set/reset button to reset the
system. The next screen indicates that
the CHANGE OIL SOON message
has been reset.
If the vehicle has the uplevel DIC, when
the gages button is pressed and the
OIL LIFE REMAINING mode appears,
it should read 100 percent OIL LIFE
REMAINING.
3. Turn the key to OFF.
Vehicles without Driver Information
Center (DIC)
1. With the engine off, turn the ignition
key to RUN.
2. Fully press and release the accelerator
pedal slowly three times within
ve seconds.
3. Turn the key to OFF, then start the
vehicle.
If the light or message comes back on when
you start your vehicle, the oil life system has not
reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that
may be unhealthy for your skin and could
even cause cancer. Do not let used oil stay on
your skin for very long. Clean your skin and nails
with soap and water, or a good hand cleaner.
Wash or properly dispose of clothing or rags
containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil
products.

Automatic Transaxle Fluid
When to Check and Change Automatic
Transaxle Fluid
A good time to check the automatic transaxle uid
level is when the engine oil is changed.
Change the uid and lter at the intervals listed
inAdditional Required Services on page 464,
and be sure to use the transaxle uid listed
inRecommended Fluids and Lubricants
on page 470.
How to Check Automatic
Transaxle Fluid
Because this operation can be a little difficult, you
may choose to have this done at the dealership
service department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading
on the dipstick.
Notice:Too much or too little uid can damage
the transaxle. Too much can mean that some of
the uid could come out and fall on hot engine
or exhaust system parts, starting a re. Too
little uid could cause the transaxle to overheat.
Be sure to get an accurate reading if you check
the transaxle uid.

B. Pressure Cap
C. Electric Engine Cooling Fans
{CAUTION:
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. Keep
hands, clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.

How to Add Coolant to the Coolant
Recovery Tank
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.If you have not found a problem yet, but the
coolant level is not at the cold ll line, add a
50/50 mixture of clean, drinkable water and
DEX-COOL
®engine coolant at the coolant
recovery tank. SeeEngine Coolant on page 363
for more information.
Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant
and the proper coolant mixture.
{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
When the coolant level in the coolant recovery
tank is at the cold ll line, start the vehicle.
