Buick 2009 Lucerne - Manual (Page 201)

CHECK TIRE PRESSURE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the pressure in
one or more of the vehicle’s tires needs 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. 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. See Tires
on page 5-57, Loading the Vehicle on page 4-18,
and Inflation - Tire Pressure on page 5-64. The DIC
also shows the tire pressure values. See DIC Operation
and Displays on page 3-52. If the tire pressure is low,
the low tire pressure warning light comes on. See Tire
Pressure Light on page 3-45.
DRIVER DOOR OPEN
This message displays when the driver door is not
closed properly. Make sure that the door is closed
completely.
ENGINE HOT A/C (Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal,
the A/C operation automatically resumes. You can
continue to drive your vehicle. If this message
continues to appear, have the system repaired by
your dealer/retailer as soon as possible to avoid
compressor damage.
ENGINE OVERHEATED IDLE ENGINE
Notice: If you drive your vehicle while the engine
is overheating, severe engine damage may occur.
If an overheat warning appears on the instrument
panel cluster and/or DIC, stop the vehicle as soon as
possible. Do not increase the engine speed above
normal idling speed. See Engine Overheating
on page 5-36 for more information.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle to
idle until it cools down.
