General description


For the cars equipped with additional restrictive system (pneumopillow):

  • Service of components or wires of system of a pneumopillow and round them should be carried out by only authorized dealer Suzuki. Non-compliance with precautionary measures can lead to inadvertent activation of the system or bring system into a non-working condition. Therefore there can be serious damages.
  • Maintenance should begin not earlier than in 90 seconds after switching off of the ignition key and disconnection of a negative cable from the accumulator. Otherwise, the system can be activated at the expense of reserve energy in the touch and diagnostic module (SDM).

The double top camshaft is established from above cylinder heads: it is actuated by the crankshaft by means of synchronization chains, and in system of a drive of the valve there are no pusher rods.
