    Hyundai Venue (QX) (2020-2024) Owners Manual: Recommended Cold Tire Inflation Pressures


    All tire pressures (including the spare) should be checked when the tires are cold. “Cold tires” means the vehicle has not been driven for at least three hours or has been driven for less than one mile (1.6 km). Warm tires normally exceed recommended cold tire pressures by 4 to 6 psi (28 to 41 kPa)...

    Hyundai Venue (QX) (2020-2024) Service Manual: Description and operation


    Description An ignition coil is an induction coil in an engine's ignition system which transforms the battery's low voltage to the high voltage needed to create an electric spark in the spark plugs to ignite the fuel. Coils have an internal resistor while others rely on a resistor wire or an external resistor to limit the current flowing into the coil from the battery 12 V supply...
