The Rio is the most popular Kia model worldwide.
The revised front bumper and Tiger Nose grille incorporate 'winglets' into the fog lamp recesses, while at the rear a new shape bumper is "more contoured and elegant".
All Rio models now have alloy wheels – base models previously had steel rims and wheel covers – with 15-inch alloys for the LX manual petrol model, 16-inch alloys for the LX petrol auto and LX diesel, and 17-inch alloys for the EX Rio.
Daytime running lights are standard on all Rio models and two new colours, Urban Blue and Digital Yellow, complete the exterior upgrade.
The car maker says inside, changes to the dashboard include chrome trim around the air vents and changes to the centre console, incorporating simplified controls to make the audio system more user friendly.
"Supervision cluster instrumentation is now adopted for the Rio range, providing the driver with better information.
"The Kia Rio continues to be one of the best equipped small cars in New Zealand, with reverse warning sensors, in-cabin headlamp adjustment, air-conditioning, remote locking with in-built car alarm, a height-adjustable driver's seat, telescopic steering wheel, split folding rear seats, rear luggage cover, auto light control, cruise control and audio controls on a leather wrapped steering wheel, Bluetooth hands-free and an MP3-compatible/radio/CD audio system with USB and AUX ports all included as part of the standard package."
The EX model also features LED daytime running and rear combination lamps, climate air conditioning with an auto de-fog system, electric folding door mirrors (incorporating LED indicators), rain sensing wipers, smart cornering lights and automatic projection-type headlights. A proximity key with push-button engine start is added to the EX model for the 2015 year.
