maybe this:

pawn Код:

public OnPlayerUpdate(playerid)
{
    if(IsPlayerInAnyVehicle(playerid))
    {
        new id = GetPlayerVehicleID(playerid);
        if(GetVehicleHealth(id) < 300)
        {
            SendClientMessage(playerid, 0xFFFFFFAA, "* You're being removed from your vehicle as it has less health!");
            RemovePlayerFromVehicle(playerid);
        }   
    }
    return 1;
}
