Every 10,000 km (6,000 miles) or 12 months. Use 0W-20 or 5W-30 synthetic oil.
Strictly Honda HCF-2 (Hydro-decomposition Continuously Variable Fluid-2). Never use traditional automatic transmission fluid (ATF-Z1 or DW-1) or generic multi-vehicle CVT fluids.
Honda All-Season Antifreeze/Coolant Type 2 (Pre-mixed blue formulation). Never mix this with water; it comes pre-diluted to a 50/50 ratio. honda jazz gk5 service manual
The Honda CVT is highly sensitive to fluid degradation. use generic ATF. Ensure the vehicle is level on jack stands. Remove the plastic underbody splash shield. Remove the CVT drain plug using a 3/8-inch ratchet drive. Clean the magnetic drain plug of any metallic sludge.
A standard workshop manual outlines these critical specifications for the 1.5L powerplant: Specification / Type L15B / L15B1 (Direct Injection) Horsepower ~130 hp @ 6,600 RPM Torque 114 lb-ft @ 4,600 RPM Spark Plugs Iridium (e.g., NGK DILZKAR7C11S) Spark Plug Gap 1.0 – 1.1 mm (0.039 – 0.043 in) Firing Order 1 - 3 - 4 - 2 Transmission Variations
Warm up the engine to operating temperature, then shut it off. Jack up the front of the car safely using jack stands.
Because the L15B engine is direct-injected, fuel does not wash over the intake valves. Over time, carbon deposits can cause rough idling or misfires. The manual details the procedure for cleaning the intake valves via walnut blasting or specialized chemical sprays. A factory manual shines brightest when diagnosing known
0W-20 (API Certified, Full Synthetic). For extremely hot climates, 5W-30 is acceptable, but 0W-20 yields optimal fuel efficiency and immediate cold-start lubrication. Engine Oil Capacity: 3.3 Liters (3.5 US quarts) when changing oil only.
Full specifications for the 1.5L i-VTEC (L15B) engine, including valve adjustment specs , cylinder head disassembly, and manual or CVT transmission fluid change procedures.
The manual emphasizes the use of specific fluids. The GK5 requires for its CVT. The service procedure for the CVT differs significantly from traditional automatic transmissions; the manual outlines a specific "drain and fill" procedure rather than a flush, protecting the internal belt and pulley system from pressure damage. Additionally, the manual specifies the use of Honda Long Life Antifreeze/Coolant Type 2 , warning against the use of silicate-based coolants that can corrode the aluminum engine components.
Park on level ground and lift the vehicle safely on jack stands. Remove the plastic under-engine splash shield. If you share with third parties, their policies apply

Inspect every 20,000 km; replace every 40,000 km.
Verdict
The official manual for the Honda Jazz GK5 (2015–2020) is not typically distributed in a single, complete book to consumers by Honda. However, it can still be accessed through several avenues.
