All 2006 Kia Rio and Rio5 models can be equipped with carpeted floor mats, but the more substantial packages are reserved for LX and SX trims. These include a four-speed automatic transmission; an antilock brake package that adds ABS, rear disc brakes, and electronic brake force distribution; a rear decklid spoiler (LX); and a Power Package, which includes power windows, power door locks, keyless entry, power heated mirrors, and tweeters for the sound system.
