nope, it clearly stated using lower pressure for winter tires.

hmm, i could have sworn it said less. i was in a 2008, this is from a 2006.

Snow tires should carry 4 psi (28 kPa)
more air pressure than the pressure
recommended for the standard tires on
the tire label on the driver's side of the
center pillar , or up to the maximum
pressure shown on the tire sidewall,
whichever is less.
Do not drive faster than 75 mph (120
km/h) when your car is equipped with
snow tires.

Anyway, a change in pressure is strange.
