The vast majority of Kia Ceed engines across both the JD and CD generations, including the 1.0, 1.4, and 1.5 T-GDi petrols, as well as the 1.6 CRDi diesels, utilise a timing chain. These are designed to be maintenance-free for the life of the vehicle, provided regular oil changes are strictly adhered to.
On JD models, the TPMS usually auto-resets after correcting the tyre pressures and driving above 15 mph for a few minutes. On CD models, there is often a physical 'SET' button located on the lower right dash panel; press and hold this with the ignition on until the warning light blinks and extinguishes.
AdBlue was introduced to the Ceed 1.6 CRDi engines in 2018 with the launch of the CD generation to meet Euro 6d-TEMP emissions standards. Earlier JD generation diesels do not require AdBlue. Ensure the AdBlue tank, located next to the diesel filler, is topped up to prevent non-start countdowns.
