2009 BUICK ENCLAVE reset

If the temperature overheat gage is
no longer in the overheat zone or an
overheat warning no longer displays,
the vehicle can be driven. Continue
to drive the vehicle slow for about
10 minutes. Keep a safe vehicle
distance from the car in front of you.
If the warning does not come back
on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see “Overheated
Engine Protection Operating
Mode” next in this section.Overheated Engine
Protection
Operating Mode
This emergency operating mode lets
the 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 distances 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. See
Engine Oil on page 5-11.
Power Steering Fluid
The power steering uid reservoir is
located toward the front of the engine
compartment on the passenger
side of the vehicle. SeeEngine
Compartment Overview on
page 5-10for reservoir location.

How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level surface.
If the level is below the bottom of
the ller plug hole, you will need to
add some lubricant. Add enough
lubricant to raise the level to
the bottom of the ller plug hole.
Use care not to overtighten the plug.
What to Use
Refer to the Maintenance Schedule
to determine what kind of lubricant to
use. SeeRecommended Fluids and
Lubricants on page 6-12.Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers ash
their high-beam headlamps at
you (for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your
dealer/retailer for service.
Bulb Replacement
For the proper type of replacement
bulbs, seeReplacement Bulbs
on page 5-35.
For any bulb changing procedure
not listed in this section, contact
your dealer/retailer.
High Intensity Discharge
(HID) Lighting
{CAUTION
The low beam high intensity
discharge lighting system operates
at a very high voltage. If you try
to service any of the system
components, you could be
seriously injured. Have your
dealer/retailer or a qualied
technician service them.
Your vehicle has HID headlamps.
After your vehicle’s HID headlamp
bulb has been replaced, you may
notice that the beam is a slightly
different shade than it was originally.
This is normal. (A) Filler Plug (B) Drain Plug

Tires on page 5-50andWheel
Replacement on page 5-55.
When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.
If the vehicle has a compact
spare tire, do not include it in the
tire rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures as shown on the Tire
and Loading Information label.SeeInflation - Tire Pressure on
page 5-42andLoading the
Vehicle on page 4-16.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 5-45.
Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
Capacities and Specifications on
page 5-98.
{CAUTION
Rust or dirt on a wheel, or on
the parts to which it is fastened,
can make wheel nuts become
loose after time. The wheel
could come off and cause an
accident. When you change a
wheel, remove any rust or dirt
(Continued)
CAUTION (Continued)
from places where the wheel
attaches to the vehicle. In an
emergency, you can use a
cloth or a paper towel to do
this; but be sure to use a
scraper or wire brush later, if
needed, to get all the rust or
dirt off. SeeChanging a Flat
Tire on page 5-71.
Make sure the spare tire, if the
vehicle has one, is stored
securely. Push, pull, and then
try to rotate or turn the tire.
If it moves, tighten the cable.

{CAUTION
Performing maintenance work on
a vehicle can be dangerous. In
trying to do some jobs, you can
be seriously injured. Do your own
maintenance work only if you
have the required know-how and
the proper tools and equipment
for the job. If you have any doubt,
see your dealer/retailer to have a
qualied technician do the work.
SeeDoing Your Own Service
Work on page 5-4.
Some maintenance services can be
complex. So, unless you are
technically qualied and have the
necessary equipment, have
your dealer/retailer do these jobs.
When you go to your dealer/retailer
for service, trained and supported
service technicians will perform
the work using genuine parts.To purchase service information,
seeService Publications Ordering
Information on page 7-13.
Owner Checks and Services on
page 6-8tells what should be
checked, when to check it, and what
can easily be done to help keep
the vehicle in good condition.
The proper replacement parts,
uids, and lubricants to use
are listed inRecommended Fluids
and Lubricants on page 6-12
andMaintenance Replacement
Parts on page 6-14. When the
vehicle is serviced, make sure these
are used. All parts should be
replaced and all necessary repairs
done before you or anyone else
drives the vehicle. We recommend
the use of genuine parts from
your dealer/retailer.
Scheduled Maintenance
When the CHANGE ENGINE
OIL SOON message displays,
service is required for the vehicle.
Have the vehicle serviced as
soon as possible within the next
600 miles (1 000 km). It is possible
that, if driving under the best
conditions, the engine oil life system
might not indicate that vehicle
service 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/retailer
has trained service technicians
who will perform this work using
genuine parts and reset the system.
If the engine oil life system is ever
reset accidentally, service the vehicle
within 3,000 miles (5 000 km) since
the last service. Remember to reset
the oil life system whenever the oil is
changed. SeeEngine Oil Life
System on page 5-13for information
on the Engine Oil Life System and
resetting the system.
