Recommended Fuel

The recommended fuel for Lucerne

models equipped with the 3800 V6

engine is unleaded regular fuel.

Premium fuel is recommended for

Lucerne models equipped with the

Northstar V8 engine. Premium fuel

enables the Northstar V8 to provide

maximum performance, but unleaded

regular fuel may be used with no 

harmful effects to the engine.

See Section 5 of your Owner Manual.

Tire Pressure Monitor

The Tire Pressure Monitor alerts you

when a significant reduction in pressure

occurs in one or more of your vehicle’s

tires by illuminating the  (low tire

pressure) warning light on the instru-

ment panel. The low tire pressure warn-

ing light will remain on until you correct

the tire pressure.

You may also have a CHECK TIRE

PRESSURE message appear on the DIC.

Correcting the Tire Pressure

When the low tire pressure warning light

illuminates, you must fill the tire to the

proper tire inflation pressure. The Tire

and Loading Information label shows the

correct inflation pressure for the tires

when they’re cold. “Cold” means your

vehicle has been sitting for at least three

hours or driven no more than one mile.

You can temporarily remove the DIC

message by acknowledging it with your

DIC controls. However, at the next vehi-

cle start-up, the DIC message will reap-

pear if the tire pressure has not been

corrected.

You may notice during cooler conditions

that the low tire pressure warning light

will appear when the vehicle is first start-

ed and then turn off as you start to drive

the vehicle. This could be an early indi-

cator that your tire pressures are getting

low and need to be inflated to the proper

level.

See Section 5 of your Owner Manual.

very firm and resistant, or anywhere in

between. The result is a suspension that

enables crisp handling, exceptional vehi-

cle control and a premium, refined ride.

See Section 4 of your Owner Manual.

Note: The Tire Pressure Monitor can

alert you about low tire pressure, but it

doesn’t replace normal monthly tire

maintenance.
